The existing metallurgical industries have stockpiles of raw materials and finished products understaffed with the required equipment, as well as separate sections of technological conversions, which does not allow the creation and implementation of new economic technologies and requires additional operational, material and capital costs, as well as the involved production facilities and complex transfer systems and interconnecting devices.

Known stand-alone continuous casting lines for flat products from Krupp-Tekhnika (1), continuous casting and rolling units for metals - prototype (2), semi-continuous and continuous hot rolling mills (3), reversible blanking mills, final cold rolling mills, as well as drives and systems for automated control, management and regulation of technological processes (4), ... (16) and other sources of domestic and foreign technical information.

Known lines, continuous casting and rolling units of metals, rolling mills and finishing lines for various purposes are made by specialized ones, which are intended mainly to perform one or two technological operations, defined by the name of the mill or unit in a narrow range of thicknesses and widths of the metal being processed. Famous mills operate in a roll or sheet-fed process and for a specific technological purpose. The equipment is equipped sequentially and on the same level.

The closest in technological and technical essence to the claimed invention is the source of information selected as a “prototype” (2) L.I. Sofiysky, I.M.

which allows you to combine technological processes and produce marketable metal products obtained on procurement, finishing, multi-roll, cladding, tempering mills and jointing and finishing units from roll or strip billet in the line of one UMPMI rolling module. The layout of the section of the universal mill is shown in the drawings sheets 2 and 3.

3.1. The work of a universal mill from a roll stock.

For harvesting or finishing rolling, the Quarto system rolls are installed in the work stand 53 of the universal mill. Before starting work, the solution of the rolls of the working stand 53 is adjusted to the required thickness of the first pass, for which the upper rolls are adjusted using an electromechanical pressure device to a given solution.

Rolls 37 obtained from a continuous casting line or from a hot rolling mill and / or other lines outside the UMPMI complex are fed one at a time from loading device 36 to a two-cone type unwinder 39 and are fixed on it. With the help of the end-of-band extractor 40, the front end of the strip is separated from the roll 37 and due to the rotation of the roll by the unwinder 39, the use of the correctly-pulling rollers of the flexor 40 is transferred to the correct machine 41 and the scraper 42 for preliminary straightening of the curvature of the strip and the necessary stripping of the specified strip, pinch roller at this time, presses against the unwinding roll 37, preventing it from fluffing. Then the specified strip is centered by the rollers 43, the defective part of the strip, if any, is cut off by the guillotine shears 46 and the flat front end of the strip through the specified wire, the feed and swivel rollers 47 and the bending-pulling rollers 51 are set by the roller table into the work stand 53.

When leaving the stand 53, the strip enters the target of the bending-pulling rollers 55 and further, moving along the rotary roller table 59, which is lifted to the upper position, the thick strip is transferred to the slot of the double support drum of the upper level winding device 58. The drive of the working stand 53 and the drum of the winder 58 are turned on, where more than one turn of the strip is wound, which ensures the necessary set tension, and the rotary roller table 59 is returned to the horizontal initial position. Then carry out rolling according to a given technology. After leaving the rear stand of the strip held by bendingly pulled rollers 55 from the working stand 53, the required solution of the rolls of the working cage is produced, the drives of the working stand 53 and the bending and pulling rollers 55 are also reversed, and the strip is fed to the working stand 53 with its rear end and then bending pulling rollers 51 with the help of a rotating roller table 47, located in the upper position, is set in the slot of the drum device winding 48 of the upper level, for winding a thick strip. Reverse rolling of the workpiece is carried out according to the scheme: winding device 58 of the upper level - work stand 53 - winding device 48 of the upper level, etc. to achieve a predetermined thickness of metal, according to the requirement of the card technology rolling. The solution between the work rolls of the stand 53 is set for each pass using an electromechanical push device.

When finishing rolling the roll strip, in addition to electromechanical, an electrohydromechanical pressing device is used to set up and adjust the solution of the work rolls of stand 53, including hydraulic cylinders interacting with the screw through a spherical thrust bearing, and a linear cylinder rod displacement sensor, which makes it possible to use a system for automatically controlling the thickness of the rolled strip by passes .

In partial rolling, winding devices 49 and 56 of the lower level with cantilever drums are used, and the task of a thin strip in their pharynx is carried out, respectively, by the rotary roller tables 47 and 59, which are in the lowest position. Pinch rollers of the bending pulleys 51 and 55 are used to reduce the roll curvature of the rear end of the strip in the roll. Reverse rolling is carried out according to the scheme: winding device 56 of the lower level - work stand 53 - winding device 49 of the lower level - work stand 53, etc. until the specified thickness is reached.

Depending on the number of passes, the rolled roll is removed by the unloading device 50 from the cantilever drum of the winding device 49 or, respectively, by the unloading device 57 from the winder 56. Finishing cold rolling according to the above-described scheme can be carried out in the presence of the initial roll on the drum of one of the winding devices 48 or 58 of the upper level.

3.2. Work of the mill from a strip blank.

Piece blanks 34 in the form of strips, sheets or cards, hot-rolled or cast, milled, are fed from the machine of the stripping 30 continuous casting line, hot rolling mill or laying device 33 one at a time to the feed roller 32, and then through the removable roller 38 and centering rollers 35, the pulling rollers 40 are set into the open multi-roll machine correct 41, where, after the rollers are brought together, the strip is straightened, centered by the rollers 43 and, through the opened stripping machine 42 and the guillotine shears 46, are fed into the solution of bending-pulling rollers 47 Olika 51 that define the front end of the workpiece 34 in the boxed working cage 53, wherein the work rolls are configured to passage thickness. The back tension of the strip during rolling is created by a roller table located at stand 53. The rolling strip 34 emerging from the stand is placed on roller tables 59 and 63, and its rear end is held by a roller table. Then, the work rolls of the working stand 53 are adjusted to the thickness of the next passage, the drive of the working stand and other corresponding machines are reversed and the next passage is carried out. The process is repeated until the required thickness is reached, and then the strip with bending and pulling rollers 55 is conveyed along the movable rolls 59 and 63 to the stop of the movable 67, set to the required measured length, flying scissors 66 are turned on and the cut measuring strip is passed through the rolling table of the cutting section 64 until the retractable 70 stops where they stop. The stacker 69 stacks the cut measuring strips in the feet. The sprinkler 65 is used when cutting short strips, as well as to dump the substandard rear ends of the strips into the box.

3.3. Work of the mill during the combined roll-strip rolling process.

The work of the mill in the UMPMI module during the combined cold rolling process is carried out similarly to work from a strip billet (Section 3.2) until the required strip thickness is reached, which is then not cut into measuring sheets and cards, and when the stop is removed, the movable 67 and retractable 70, through The opened flying scissors are set in a rolling machine 72, where the strip is rolled up into a roll 74 and transferred to the drive 73 for further technological processes. If necessary, the winding of the rolled strip can be carried out by the device winding 58 (48) of the upper level or device winding 56 (49) of the lower level.

3.4. Work of the mill during the final cold rolling of thin and thinnest tapes and strips.

Instead of working rolls of the Quarto system, a work stand 53 is filled up with the installation kit for a multi-roll cassette 75, drawings of sheets 2 and 3, containing rotary cassettes fixed with wedges with a rack and pinion moving mechanism placed on the support beams. Installation of the roll gap and the selection of all backlash is carried out by hydraulic cylinders mounted on the supporting beams and interacting with the work rolls through the levers, as well as by turning the eccentric axes. The lower work roll of the multi-roll cassette 75 is set to the rolling level by the same mechanism as the lower work roll of the Quarto system (Section 3.1). Axial movement to adjust the profile of the strip and fixing the pillows of the intermediate rolls of the multi-roll cassette 75 is carried out by the drive provided through a screw pair and a kinematically connected axial displacement sensor.

The loading of the rolls, the transfer of the front end of the strip to the work stand 53, its task in the winding device 56 of the lower level is carried out similarly to cold rolling of a roll stock (Section 3.1). Rolling is carried out according to the scheme: winding device of the lower level 56 - work stand 53 - winding device 49, according to the requirements of the card of the technological process of rolling.

The thickness of the rolled strip in each passage is continuously monitored by 52 m thickness gauges and is controlled by the “automatic strip thickness control system” using a built-in quick-acting electro-hydromechanical push device. The rolls are removed after rolling, depending on the number of passes, from the winding device 49 or 56 of the lower level using the unloading device 50 or 57.

3.5. The work of the mill in training mode.

Using a work stand 53, where the pressure devices adjust the pressure to a compression ratio of 1-8%.

4. UMPMI IN THE MODE OF LAYING OF MULTILAYER COMPOSITIONS AND ALLOYS (drawing sheet 2, figures 1 and 2)

4.1. The work of the universal mill when cladding a trimetallic or bimetallic strip.

Cold rolled production of a rolled multilayer strip is more productive and economical. Consider the operation of mill equipment, for example, for cladding a trimetallic or bimetallic strip consisting of a base (middle layer) and cladding components (extreme upper and lower layers). To do this, adjust the working stand 53, load the roll 37 of the base strip and transfer its front end to the stripping machine 42, which is pre-adjusted to the thickness of the base strip, and then transported to the bending pulleys 51, where it is stopped by the sequence described in (clause 3.1). Rolls of strips of cladding components are loaded into unwinders of upper level 44 and lower level 45. The front ends of strips of cladding components are fed to the rollers by bending-pulling 51 so that the front end of the strip of upper cladding component is aligned with the front end of the base strip and the front end of the strip the lower clad component protruded beyond the front ends of the other two bands. The bending pulling rollers 51 are closed by clamping the strips with the pinch roller movement, the front protruding end of the lower cladding component is bent around the front ends of the base strip and the upper cladding strip, and then all three strips are fed with bending pulling rollers 51 to the rolls of the work stand 53, where they are compressed to 60-80% per pass, depending on the technology and structure of the specified cladding strip compositions. Next, the strip is sent to the target of the bending-pulling rollers 55, which, by means of the pinch roller and the rotary live roller 59 with movable wiring, define the front end of the trimetallic strip in the throat of the cantilever drum of the lower-level winding device 56. Separated from the trimetallic strip as a result of rolling, the edges of the strips of the cladding components of the upper and lower left and right sides are transferred through special wires for winding with the edge coiler 54 to the scrap waste bay for further remelting.

The slagged roll of the trimethal strip is rewound to reduce the inter-turn tension of the strip from the winding device 56 to the drum of the winding device 49 with a low tension of the slag strip, from where the roll with the trimetal is removed by the unloading device 50 and transferred for further processing.

The cladding process of monometals can be carried out with one-sided or two-sided coating of the base strip.

4.2. The work of the universal mill of the UMPMI module in the production of multilayer compositions with a different number of layers and special alloys.

The use of technological equipment of the mill in the mode of production of multilayer compositions with a different number of layers and special alloys and monometals, i.e. more than three layers of incoming components, carried out similarly to that described in (clause 4.1), while for the task of components in an amount, for example, up to five or more can be used as unwinder clad components prepared for this process, additional special unwinding devices, structurally executed on the basis of coilers 49 of the lower level and 48 of the upper level. The rest, similar to the cladding process by the method of cold rolling, is described earlier in (Section 4.1). Such a technical solution to the designs of devices of equipment layout machines is aimed at creating new technologies for the production of rolled metal and products for the electronic, instrument-making industry and a number of other special purposes.

The UMPMI module complex provides equipment 60 for preparing technological components for cladding of multilayer metals.

5. OPERATION OF THE “UMPMI” MODULE IN REWIND UNIT

Rewinding the strip into rolls to reduce interturn specific tension and controlling the surface quality of the strip and tape, including in the production of multilayer metals, as well as thin and thinnest tapes, is traditionally carried out on separate units. This invention provides for the purpose of optimizing the use of combined production technologies, the composition of the use of equipment, working areas and operating costs, to combine the use for technological processes of rewinding and control of the roll strip, using lower-level winding devices 49 and 56 with cantilever drums and unloading devices 50 and 57 universal cold rolling mill module "UMPMI". This technical solution eliminates the phenomenon of sintering of the strip coils in a roll at high specific strip strains during the rolling process.

When rewinding the rolls of the working stand, 53 is bred to a gap exceeding the thickness of the rewound strip, and the electric drive of the winding device that performs the function of the unwinder is adjusted to the minimum tension value specified by the technology. It is possible to rewind the strip from the winding top level device to the drum of the winding lower level device, if required by the process.

6. OPERATION OF THE “UMPMI” MODULE IN THE MODE OF THE TRANSVERSE CUTTING UNIT OF ROLLED ROLLS AND STRIPES FOR DIMENSIONAL SHEETS AND CARDS (drawings sheet 2, 3 and 4)

The initial roll, depending on the thickness of the continuously cast, hot-rolled, cold-rolled and clad strip and the previous technological operation, is fed to one of the unwinding devices - winders 39, or 49, or 48, or the original continuously cast or hot-rolled straight strip, the front end of the strip which is carried out to the rollers of the bending-pulling 51, then the cage of the working 53. The roller of the pinch bending-pulling rollers 51 and the repeated roller conveyor 47 are set in the horizontal initial position, turning on the role electric drives of bending-pulling 51, work stand 53 and other machines at working speed, they begin to transport the rolled strip along the roller tables 59 and 63 through the open guillotine shears 61 and centering rollers 62. A follower roller with a sensor for controlling the length of the moving strip is connected using a tracking automation system dimensional cut with a pulse encoder encoder electric flying scissors 66, ensure their synchronization with the speed and length of the cut strip, and also automatically give the command to execute the device in and the required cutting of the strip into sheets and cards of measured length, which are fed to the live rolls of the cutting section 64 and 68 to the raised stop 70. From the live roll 68 of the cutting section, the cut sheets and measured length cards are removed by the stacker 69 and placed in the finished product stops, which are then packed at section 82 and then transferred to the finished product warehouse 89 for automated accounting by system 90 and shipping to consumers. Cutting strips into measuring sheets and cards, as well as their stacking in the stacks of finished products is described in the description (Section 3.2).
