Product Description

Automatic Gauge Control Metal Cold Rolling Mill has Automatic Control System of Cold Rolling Process.

Main composition:
Electric control of main drive
Electric control of auxiliary drive
Basic automatic control

Composed of Siemens SIMATIC S7-400 PLC, ET200M slave station and HMI system, the rolling mill automation system is a kind of distribution automation.
S7-400 PLC and several remote I/O slave stations ET200M fulfill all logic control and order control of the rolling mill, while HMI system is to set and monitor working parameters.

The main drive are DC motors, auxiliary drive are AC frequency motors, the non-regulating AC motors are normal asynchronous motors.
Three DC motors are controlled by Siemens 6RA80 DC controller
AC frequency motors are controlled by Siemens SIMOVERT MA

Cold Rolling Mill Automatic Control System

our 4hi reversible cold rolling mill line comply with high Quality Standards (Acceptance Standards for Domestic Well-known Enterprises such as Antai, MCC, North Heavy Industry, etc.) and match with Danieli, Andritz mills precision.
