Abstract

PURPOSE:To obtain a uniform surface roughness over the entire region in the rolling direction of a temper rolled plate by adjusting adequately rolling force according to rolling speeds. CONSTITUTION:The rolling speed signal of a strip 1 detected with a speed detector 3 connected to the work roll 2a' of the No.2 stand is converted by a signal converter 4. The converted signal thereof and the blank material conditions of the strip 1 as well as the rolling force signal fed from a rolling down force detector 8 with a converter 9 for rolling force signal are added and the rolling down force satisfying the relation P=f(V) (P; rolling down force, V; rolling speed) is calculated with an arithmetic device 5. The output thereof is amplified with an amplifier 6 and is delivered to a control mechanism 7 for rolling down force so that the strip is rolled under the prescribed rolling down force.
