Research and control for rolling torque of the heavy plate mill

Sometimes main driver motors' torque exceeds the maximum limit in Baosteel's 5 m heavy plate mill. Experience showed that torque overloaded occurred in cases of some special rolling sequence and special rolling plate dimension.Most of the overloaded occurred only instantaneous at some time point during the rolling pass, which especially easily happened at the bite and motor acceleration time after the bite.This paper analyzes the impact factors for motor torque overload and carefully studies the key details...
