9 RSA - Roll Spalling Alarm and Quick Stop System

During the rolling production process of the rolling mill, the rollers are in a complex stress state. The periodic thermal stress caused by contact heating between the rollers and the rolled piece, water cooling of the rollers, contact stress caused by rolling load, shear stress, and residual stress, etc., such as unreasonable material selection, design, manufacturing process, or local heating caused by steel sticking during rolling, can easily cause roller failure. Roll peeling is the primary form of roller failure.

Based on the characteristics of the process data before roll peeling, the Roll Spalling Alarm and Rapid Stop System can issue warning and rapid stop signals. At this time, only the roll needs to be pulled out for inspection normally to avoid the impact of complete roll peeling on other systems and long-term fault handling.
