Abstract

PURPOSE: To derease the deflection of plate width along the total length of rolling material, by controlling the velocity and rolling reduction of the last stand of hot finish rolling mill based on the period from arriving the rolling material at down coiler to passing through the last stand and exit side tension of the last stand etc.
