The MKW Cold rolling mill (Partial eight-roll mill )can be used as a roughing mill before the twenty-roll mill. Therefore, the eight-high mill has a faster development and a wider range of applications. It can be used for rolling carbon steel, stainless steel, silicon steel, alloy steel and cold-rolled hard-to-deform steel, as well as thin strips and foils for non-ferrous metals.
MKW Rolling Mill (Biased 8 roller Cold Rolling Mill)
The MKW rolling mill is a kind of small diameter working roll and a unique cold rolling mill. It is a multi roll rolling mill on the basis of the four roll mill of the supporting roll. Because of adopting small diameter work roll and roller adjusting device, the working roll position is relatively stable, and the horizontal rigidity is high. The maximum reduction is up to 40-60%, which is a non-traditional multi roll cold rolling mill appeared in modern times. The output of eight high rolling mill can meet the requirements of strength and rigidity of rolling needs and overcoming the lateral bending of working roll. It also has simple structure, easy adjustment, good working stability, reversible rolling, increasing the pressure, reducing the pass and simplifying the cold rolling process (that is, reducing the intermediate annealing times) and improving the output quality, etc. The eight-high mill can be used as the roughing mill before the 20-high mill. Therefore, The MKW rolling mill is developing rapidly and has a wide range of application. It can be used for rolling carbon steel, stainless steel, silicon steel, alloy steel and cold rolled refractory steel, etc. It is also suitable for non-ferrous metal strip and foil.
1450mm MKW Reversible Cold Rolling Mill
The production of this unit is to roll picked stainless steel coils with the thickness of 1.5～3.5mm into high precision cold rolled coils with the thickness of 0.3～1.0mm through several time of rolling. It adopts single-stand MKW reversible cold rolling mill, The large tension coiler and thickness gauge etc, which can realize large tension rolling and guarantee high-speed and stable production with specified thinness.

4. Equipment Level
1) The main rolling mill and coiler drive system adopts Siemens 6RA80 full digital DC speed regulation, thyristor power supply and unit PLC control.
2) The basic automation system of the unit is composed of Siemens S7-400 series PLC as the main controller, which is combined with the corresponding remote I/O (ET-200M) to control the operation of the rolling line and auxiliary equipment.
3) The AGC is an automated thickness control system with FM458 function modules. Full hydraulic pressure. It has constant roll gap control, constant rolling force control, adjustment control, automatic prepressure control, thickness precontrol AGC, thickness monitoring AGC, tension / speed AGC, acceleration and deceleration AGC compensation control, roll eccentricity compensation and so on, as well as rolling process database, data display and operation control, product quality tracking function, high speed rolling Process management functions such as automatic data recording, automatic report generation, fault alarm and recording.
4) The upper and lower support rollers are separately driven to reduce the consistency of the roller diameter.
5) The rolling mill electrical system has safety protection measures such as overload protection, broken belt protection and emergency stop; the unit has automatic deceleration with tail, accurate parking and multi-point parking function; the coiler has lap number memory, belt length calculation, and accurate support roller shaft GPS.
6) The unit has functions of presetting process parameters, detecting process parameters and key parameters of equipment, displaying, alarming and storing records.
7) The main operation console is equipped with man-machine interface, which completes the rolling mill status screen display (winding tension value, current value, speed value and other main process parameters) and manual adjustment, rolling process parameter setting, fault alarm and printing report.
8) The gear adopts five grade precision 20CrMnMo alloy steel carburized quenching gear and oil injection cycle lubrication.
9) Low-voltage hydraulic system components are well-known products produced by domestically introduced technologies; key components of high-pressure AGC systems use imported products.
