Technical Level of the Set

Total digital DC timing, supply of electricity with thyristor, PLC control

of the set. Full hydraulic pressure, AGC automatic control.The electronic

control system of the rolling mill is equipped with security protection system,such as overload protection, band breakage protection, emergency shutdown, etc. and both rolling mill and coiler have the functions of shutting down accurately, recording number of coils, automatically decelerating and shutting down in band tail. Automatic alignment of CPC of uncoiler. Adjustment of positive and negative bending roll of working roll and of positive bending roll of intermediate roll; the set of lateral movement of intermediate roll matches with the segmental cooling of rolls, so as to make better profile shape available. Rapid change of rolls of working roll and intermediate roll. Automatic control and digital displays of rolling speed and tension. Once the elevation of rolling line is pressed down, the screws are being adjusted at high speed.Oil-mist lubrication in bearing of rolling mill.

The equipment has the system for presetting of process parameters, detections and displays of technological process parameters and key equipment parameters, and automatically diagnosing and warning failures. The sets production processing chain and failure warning adopt Programable Logical Controller (PLC) to achieve automation.
