Customized MKW / Biased 8 roller stainless steel Reversible Cold Rolling Mill /Production line/Equipment/Machine
- Brief Introduction
The MKW Cold rolling mill ( or called partial 8-hi Cold rolling mill/Biased 8 roller cold rolling mill) is a unique cold rolling mill with small diameter work roll. It is a multi-roll mill that adds side support rolls to the work rolls on the basis of a four-roll mill supported by a backup roll.

5. Equipment Level
- The main rolling mill and coiler drive system adopts Siemens 6RA80 full digital DC speed regulation, thyristor power supply and unit PLC control.
- 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.
- 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.
- The upper and lower support rollers are separately driven to reduce the consistency of the roller diameter.
- 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.
- The unit has functions of presetting process parameters, detecting process parameters and key parameters of equipment, displaying, alarming and storing records.
- 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.
- The gear adopts five grade precision 20CrMnMo alloy steel carburized quenching gear and oil injection cycle lubrication.
- Low-voltage hydraulic system components are well-known products produced by domestically introduced technologies; key components of high-pressure AGC systems use imported products.
