METHOD FOR CONTROLLING TEMPERATURE OF STRIP INTO FINISHING MILL STAND

摘要

A method for controlling the temperature of a hot rolled steel sheet threaded from an head of a finishing mill to a tail of the fishing mill includes: a calculation step for calculating the lengthwise temperature deviation (K) of a hot rolled steel sheet in the head; and a heating step for increasing the heating temperature for heating the hot rolled steel sheet from the front end to the rear end of the hot rolled steel sheet.
