Ferrous metal (steel) and non-ferrous metals (copper, aluminum);
The transmissions used include constant speed transmission of AC and DC motors, variable speed transmission, pneumatic and hydraulic transmission.
System composition
Control system platform
The drive control and automation control system hub based on ABB, Siemens, A-B and other mainstream control system platforms is the basis for the realization of the entire system function.
Control system structure
Using the principle of distributed control, PLCs and personal computers are used as practical workstations, which are connected to each other through a data bus. The entire control system will be divided into:
System communication/network;
Main control system and on-site control system;
Operator workstation;
Engineer workstation;
Production assistance management system;
System communication network
Communication networks such as TCP/IP, Profinet, Profibus_DP, and Modbus are used to realize communication at all levels of the system.
Operator workstation
Based on the operator interface of the WinCC platform, it is responsible for the monitoring and life-changing interaction of the mill drive system parameter setting and production preparation, mill speed and tension control, and coil diameter measurement.
Engineer workstation
Based on the engineer's interactive interface of the control system windows system platform, it is responsible for controlling and optimizing the parameters related to the rolling mill frame action and thickness automatic control effect, diagnosing system faults, generating production reports, and creating interfaces with the MES system.
