Cold Rolling Mill Automation System – Detailed Case Study

Cold Rolling Mill Automation System – Detailed Case Study

The ITC system consists of separate control modes for initial mill threading and steadystate rolling. The threading control mode is configured specifically to establish interstand tension during initial threading. The steadystate or run control mode is configured to reduce interactions between interstand tension and strip thickness.
