Universal cutting system (УРК)

Application of the foam concrete cutting equipment (УРК)

УРК is used in manufacturing lines for producing autoclaved and non-autoclaved gas concrete for receipt of wall and partition blocks with geometrical imperfection from the specified size not more than ±2мм.
Blocks produced on УРК have smooth surface without oil film. Guaranteed cutting accuracy enables to lay blocks on a thin-layer or adhesive solutions.
УРК design allows to produce blocks with various standard sizes using only one kit of forms.
УРК mold is simple in production process. Cleaning, lubrication and assembly for one mold (0,9 m3) takes about 2-3 minutes.

Materials for foam concrete manufacturing

Cellular concrete with the uniformly-cellulated structure, manufactured according to GOST 25485-89 is used for cutting. Material. cured enough for steady cutting (4-12 hours after filling in the form). is used on УРК.

Technological process / foam concrete cutting

After being filled into moulds foam concrete becomes up to necessary strength (4-12 hours depending on the structure and producing technology) at 20-300°С. After that mold with cured massif is placed onto the transportation trolley of the УРК, the top of the metal mold (a cap) is removed, the operator pushes the START-UP button on the control panel and massif is cut into blocks of the specified size in automatic mode. During this procedure a thin layer of the top and edges of the massif are cut off.
After this the cut massif is removed with the pallet from the transportation trolley of the УРК and cures for another 4-8 hours, then blocks are laid on wooden pallets, packed with film and moved to the warehouse.

Control panel has speed of lowering of cutting cars control system, that allows to establish necessary frequency of the block surface finishing (from smooth up to deep wave).

The nomenclature of produced blocks

The minimal thickness of the block – 75мм.
The maximal thickness of the block – is limited by the linear dimensions of the massif.
Within the massif size it is acceptable to fix any necessary dimensions.

Porous concrete massifs on the automated contour bend machine

Porous concrete massifs on the automated contour bend machine with electro-programming control “ÐÈÔ-1»

The main aim of production porous concrete items is production of quality products with maximally possible level of specified sizes. Concerning physical-mechanical characteristics of products, made of porous-concrete, it’s obvious that they’ve reached rather high level. But if to speak about geometry – dimensions accuracy and surface quality of wall blocks of majority of producers are usually lacking. Geometry and quality of blocks surface are determined by using technology of formation.

There are many different kind of mechanisms for getting foam concrete and gas concrete mixtures, but only four techniques of wall blocks forming are known at the time.

1. Pouring of foam concrete into bar moulds – the simplest and widespread technique. Working under this technique it’s possible to get blocks with accurate geometrical size using only expensive heavy-gage sheets metal moulds. At seeming simplicity of this technique it’s necessary to have great stock of difference size moulds, that unreasonably increases steel consumption and, consequently, equipment cost. While forming a foam concrete block a peelable cement film with hydrophobic properties is generated on the sides, contacting with metal mould walls. This film makes difficulties while plastering. That’s why it’s desirable to make cutting of side surfaces. Besides pouring of foam concrete into metal mould does not give to blocks accurate edges and right angles. This causes their worse positioning while laying and, consequently, degrades its quality.

2. At the present time the structural cutting on a certain stage of getting the plastic strength by cellular-concrete raw-massifs becomes widespread, but this technique possesses a number of considerable shortages.

Firstly, the dimensions accuracy of blocks is not enough because of string walking, especially in cases of its sliding on the side faces of blocks (so-called «barrel» defect), that prevents laying such blocks on clue and lowers the quality of laying on the mortar.

Secondly, short cutting of the middle bottom block part, which is caused by considerable length of the string and impossibility to provide its enough tension, by horizontal position of strings and rounding by string high-density inclusions – leads to breaking off of the corner pieces.

Thirdly, blocks cutting at a certain moment of technological cycle needs thoroughly technology observance and does not allow to accumulate massifs before cutting, that lowers technology flexibility.

Wavy sides surface after cutting can be estimated as advantage of string cutting technique. The products surface after cutting has small tracery, which promotes better adhesion between masonry mortar and mortar for plastering. Packed surface layer has variotrop structure, its peeling wasn’t observed.

3. Cutting with circular blade saw also has a number of considerable shortages:
– to cut 600 mm height monoblock it needs one disk with large diameter or two disks precisely matched in the cutting line. Either the first, or the second decisions are rather expensive. Disks wobbling leads to low-quality cutting.
– disk (disks) sharpening requires special equipment and is expensive procedure;
– coming in and out of the spinning disk into massif body results in extraction of foam concrete pieces – chippings on blocks are formed. To solve this problem the monoblock needs to harden more, but in this case much dust will be generated during gutting process and cutting saw teeth are abraded faster.

4. Cutting of massifs with closed chain and belt saws has recently acquired more and more adherents. Different Russian manufacturers developed several types of cutting lines and machines. The specific feature of cutting technology on such lines is the necessity to separate massif from the pallet and further multiple tipping of sawn half-finished blocks on several sequentially set contour bend saws during cutting process. The massif should have enough mechanical strength (1.0 MPa and higher up to final strength of the type). This implies the necessity the prolongation of the process of porous concrete mixture curing in metal mould, that reduces to lowering of their turnover, increasing of metal moulds stocks, increasing of volume and area of heat-humidity treatment chambers. Besides, tipping process need additional equipment installation and because of heightened strength of cutting massifs it’s necessary to use expensive belt saws with special carbide teeth, which abraded too fast and this causes abrupt increase of the prime cost of the cutting process.

Besides heightened energy consumption this technique has one more disadvantage – dusting.
In spite of shown disadvantages, in existing value system, when the quality of the product is the first importance fact and becomes the main competitive advantage, producing wall blocks made of porous concrete using mechanical technique comes to the foreground.

On the basis of analysis of the wall blocks production on various famous Russian equipment using belt saw, OOO “IIC” specialists came to the conclusion that majority of abovementioned disadvantages can be eliminated if massifs are sawn after stage of gaining plastic strength within the stage of hardening beginning, when the string cutting technique can not be used by this time.

Firstly, massifs can be cut on the bottom part of the ôîðìîîñíîñòêè, thereby exclude operations of separating and tipping of monoblock and semiblocks.

Secondly, the necessity to use expensive imported carbine saw falls away, cutting process is carried out by cheap Russian belt metal saw in standard model, without carbine teeth.

Thirdly, only one saw is used for cutting.

Fourthly, there is no dusting, because cellular-concrete mixture has certain humidity at cutting moment.

Besides this, it’s important that time period for cutting fulfilment is considerably longer if to compare with string cutting and it’s possible to accumulate dismantled massifs before cutting.
Starting developing of a new contour band machine OOO “IIC” specialist used their own long experience of developing and manufacturing string cutting machines (“ÓÐÊ-2”, “ÓÐÊ-2ì”, “ÓÐÊ-3”). There were produced more then 70 such machines since 2002 up to 2007. At the same time permanent experimental-designing works and researches of new in essence technique of porous concrete raw-massifs cutting using different types of belt saws took place. After prolonged and numerous tests they were managed to find the optimal parameters of cutting mode and choose the most multipurpose type of belt saw. At the end of 2006 as the result of done work the unique cutting equipment of a new generation was created – automated bandsaw cutting machine with electronic-programmed control «Ðèô-1» for cutting large, 1240?12400?610 mm sized, cellular-concrete massifs.

The machine set includes unit for cutting the top side of the massif, one horizontal contour band module and è coordinating-transporting unit. All the mechanisms variable-frequency electric drive. «Ðèô-1» is equipped with convenient and easy-to-work control panel. Necessary dimensions of cut (block dimensions) are set on electric panel of operator. None of additional operations for machine changeover for new sizes are necessary. Besides, the display on the operator panel shows the analysis of machine work in real-time mode. Manual control is provided for adjustment the machine or for working in semiautomatic mode. Positioning and transporting of the cutting massif takes place on the coordinating table of the machine.

The machine works like that: pallet-trolley with massif, hardened enough, is taken by special positioning transporter and goes to cutting machine «ÐÈÔ-1». At the first stage the top side of the massive is cut off by screw cutter (up to 30 mm) and block length is formed (600 mm). The bottom side of the massif has strictly horizontal surface due to usage of rigid thick-walled bakelized veneer sheet in the pallet. At the second stage cross and length cutting of the massif by horizontal saw with sequential number of cycles of cutting module lifting and lowering takes place; cutting step and width and height dimensions are fixed by the coordinating table operation. After this parted into blocks massif is rolled on the overpassing trolley to the pushing transporter to be places into tunnel thermos chambers for heat and humidity treatment.

Besides this, «Ðèô-1» can be equipped with a belt knife for calibration of top and bottom sides of massif under special order.

Machine can operate with saws of two types:
– cutting massifs with gained plastic strength;
– cutting massifs with gained designed strength.

Wall blocks, produced of not-cured gas concrete using progressing vibroimpact technology

This is the first time in world-wide practice of production of porous concrete, when the technological production scheme, which provides integration of best Russian technological achievements in the sphere of porous concrete mixture forming on the basic of impact technology and technology of raw massifs cutting out on contour band machine of a new generation with quickly programming adjustment for getting practically any set size wall blocks, which does not have any analogs among world practices, are integrated.
Due to using impact technology this technological production scheme provides reducing of cement consumption up to 150 – 200 kg / 1 m3 of final product (if ash of power station and blast-furnace slag are used), reducing of the final concrete humidity and shortening of massif hardening period before cutting it into products of the set size – this in turn reduce considerably metal consumption for necessary board equipment. Besides this, implementation of impact technology and automating control system of the concrete mixture dosing allows to produce porous-concrete products with bulk density 350-700 kg / m3 with high physical-technical characteristics of final products up to domestic and world standards. Cutting machine “ÐÈÔ-1” with further massifs cutting into products of the set size with accurate within ± 1- 1,5 mm allows to produce blocks, using which it becomes possible to make masonwork on the building clue not more then 3 mm throat thickness.

Technological process description

Preparation and raw materials storage
Cement and è fine-dispersed filler from cement trucks or near-railroad discharge device with the help of compressor system of pneumatic transport are fed into silos. Cement silo and filler silo are placed in immediate proximity to components dosing-mixing unit (CDMU).

Cement and filler go from silos to the measuring hopper along horizontal or combined lifting screw. Dry and liquid components dosing is made with the help of industrial processor.
At the beginning of each shift water is poured into special tanks of dosing unit for liquid components “3ï” through piping system. Aluminium suspension is prepared in the mixer (unit for suspension preparation) from aluminium powder, surface-active materials and water. Water, aluminium powder and surface-active materials, which are continuously mixed, enter the mixer through the dosing unit. For permissibility the mixture has ventilation, double coating for water cooling and emergency sewer. The mixture also has thermal reley which switch on automatically all emergency equipment if the temperature level becomes higher the 20°Ñ. Portion of suspension, volume accordingly to receipt, is sent by pump to special tank for weighting in mixing compartment.

The powder and surface active materials solution are added into the tank with mixing unit or preparation of aluminium suspension. All necessary reagents are added into the tank for chemical admixtures solution. Liquid components (aluminium suspension solution and chemical admixtures solution) are mixed, brought up to the set temperature and are dosing into the mixer in accordance with the program. To keep efficiency and energy saving it’s recommended to pour into the ÑÄÆÊ (dosing unit for liquid components) – “3ï” warm water (not less then 10-12°Ñ).
Components mixing.
Mixing of all dry and liquid components has several stages. Control, processing and managing of all important functions takes place on the central control panel of the plant at all stages of gas concrete mixture preparation. The preparation of porous-concrete process in whole is managing from the control panel, located under the mixing tower and near the post of pouring mixture into moulds. Components dosing and process of porous-concrete mixture blending go on fully-automatically and are controlled by managing computer, where all receipts programs for producing of porous concrete of requested quality.

Operator in the real-time mode keeps track for all processes on the machine. In case of need the operator will be able to modify or change for a short time current composition, mixing time, temperature mode and other technological parameters on the main electronic control panel or using PC. Besides this the operator can change the operating mode to semiautomatic or manual control mode.

Massifs formation, cutting and transportation
Ready mixture is unloaded into metal mould through the bottom orifice of the mixture. The massif mould consists of two parts: a pallet and removable mould. The pallet is a kind of trolley with four steel wheels with basic made of bakelized plywood, which juts out over metal frame. The removable mould consists of two “Ã-shape” parts, which form four sides of massive when they are assembled. Before pouring of gas concrete mixture the removable mould is assembling, lubricated by special lubricant or is interlaid with oiled paper and set to the mould.

Moulds are sized with special sealant to provide tight connection. To prevent damages
during transportation the sealant is delivered separately from moulds and is sized himself by the Client.

After vibroimpact treatment the mould. Filled with gas concrete mixture with the help of positional conveyor is transferred to the place, where it gets stripping strength. Time for gaining the stripping strength depends on many factors (specific composition, cement type, temperature, filler type and so on) and varies from 4 till 8 hours. To provide high level of strength characteristics of material it’s very important to keep rigid thermal mode. Dependently on used materials it’s necessary to keep temperature on the level 40-50°Ñ on the side before massif cutting (3-4 hours) and 90°Ñ n the side after massif cutting (up to 20 hours). More precise thermal mode the Client set accordance with results of control check-up. When the time for gaining stripping strength runs out the removable mould is disassembled and massif on the pallet is sent to the cutting place. The mould is taken off and assembled again, set on a free pallet and sent for pouring under ÄÑÊ (dosing-mixing unit).

When the massif gains necessary plastic strength it’s taken by special position transporter and taken to cutting machine. The top part of a massif (till 5 mm) is cut off via screw cutting or belt saw at the first stage. The horizontal cutting of the bottom massif part on the special contour band machine is made on the second stage. Length and cross cutting of the massif on the cutting machine “ÐÈÔ-1” occurs at the third stage. After these operations parted massif is transported to the pushing transporter on a overpassing trolley to be sent to chambers of heat and humidity treatment. To keep thermal node of heat and humidity treatment the Client is recommended to build air-tight tunnel chambers with heat insulation of all surfaces. Due to thermal treatment in thermos mode heat energy and steam, which exude during exothermal reaction of cement hydration, are used maximally. We have such rested experience to install such “thermos”-type chambers to use exothermal effect of reaction of cement hydration. After stage of heat and humidity treatment parted massif on the trolley is rolled out for disassembling. Blocks are laid on transportation pallets, tighten with binder tape and are taken to the storage platform or storage room by loaders. Further maturing time for ready blocks at positive temperature is set by the Client and varies from 1 till two weeks. Free pallet is cleared, covered by polyethylene film or oiled paper and is taken to the pouring zone.

Besides chemical agents are applied to acceleration the structurization of plastic durability, solidification, etc., and also foam former manufactured by Limited Company “IIC”.

The description of technological process

Preparation and warehousing of raw material
Cement and milled inert filling from cement carriers with compressor installation are loaded into silos. The silo of cement and the silo of filling are located in immediate proximity from ÄÑÊ (dosing unit amalgamator of components).
From silos cement and filling move to dosing units bunkers by means of horizontal or combined screw conveyors. Dosing of dry and liquid components is carried out by means of the industrial processor.
Water through the system of pipelines is filled in special tanks ÑÄÆÊ-3Ï before the shift beginning. In a tank for foam former aperture the concentrate of foam former, and in a tank for chemical agents necessary reagents are added. Liquid components (the concrete chemical agents) are mixed up, lead up to the set temperature and under the program are dosed out in the amalgamator. Thus the concentrate of foam former automatically mixes up with air in special foam generator up to the set frequency rate and as technological foam moves into the amalgamator. For maintenance of productivity and economy of the electric power it is recommended to fill in ÑÄÆÊ – 3Ï with warm water (not below 10-12° Ñ).

Mixing of components
Mixing of all dry and liquid components occurs in several stages. On the central control panel the factory makes the control, processing and management of all important functions of installation over all sites of preparation of aerated concrete mixes. The operator in the real time mode of traces all processes of operation of installation. In case of need the operator in a short period of time can correct or change the current structure, time of mixing, a temperature mode and other technological parameters on the electronic panel of the main board or by means of a computer. Also the operator can transfer the operation of installation in semi-automatic or manual control mode.

Formation, cutting, transportation
The ready mix through the bottom mouth of the amalgamator is unloaded into the metal form. The form of a file will consist of two parts – the pallet and a demountable curb. The pallet represents the carriage on four steel wheels with the wooden basis projecting above a metal skeleton. The demountable curb will consist of two parts the “ã” -shaped form and in assembled state forms four sides, forming the massif. Before filling with aerated concrete mixes, the demountable curb is assembled, lubricated with a special solution or laid by an oiled paper and put on the pallet. For maintenance of tightness, joints of the form are glued by a special sealant. In order to prevent damages during transportation, the sealant is delivered separately from forms and pasted by the Customer.
After filling with aerated concrete mix, the form by means of the positional conveyor, is delivered to a place of ensembling of stripping strength. Time of ensembling of stripping strength depends on many factors (concrete structure, brand of cement, temperature, etc.) and changes from 4 up to 8 hours.
For maintenance of highly strengthening characteristics of a material it is very important to provide a rigid temperature mode at the moment of strength ensembling. Depending on used materials it is necessary to maintain temperature of 40-50° C the section before massif cutting (4-8 hours) and 60-90° C the section after massif cutting (up to 16 hours). More exact temperature schedule is established by the Customer in an operating mode according to the results of control supervision. For providing of conditions of a mode heat and humidity processing, it is recommended to the Customer to organize hotbed designs or stationary tunnel chambers.
At the expiration of the strength ensembling period the demountable curb is disassembled, the pallet with the massif moves to a cutting section. The curb is cleaned, assembled, oiled, and installed on the free pallet and moves to filling under ÄÑÊ.
The massif, which has gained necessary plastic strength, is captured by the special positional conveyor and moves for cutting. At the first stage by means of screw milling cutter the top is sheared off the massif (up to 5 mm). At the second and third stage cross and longitudinal massif cutting occurs. After that the massif cut into blocks is rolled to a pushing conveyor for submission into chambers of heat and humidity processing. There is an experience of the tested variant of the arrangement of such chambers as “thermos” with use of exothermal effect of reaction of cement hydration.
If the Customer uses sand or large screening as fillers, there is a probability of pilling of material with subsidence of larger particles on the massif bottom that can result massif undercut. In this case in the wooden basis of the pallet technological flutes are slitted for passing of cutting strings up to the metal skeleton.

After the stage of heat and humidity processing, the cut massif is rolled out on the carriage on disassembly. Blocks are stacked on shipping pallets, pulled together with a fastening-tape and with the help of transporting mechanisms move to warehouse platform or to warehouse. The further curing period of finished blocks at positive temperature is determined by the Customer and makes from one to two weeks. The released pallet is cleaned, interlaid with layer or with oiled paper and brought into filling zone.
