Abstract

PURPOSE:To make operation stable by setting the rolling reduction at a final stand by a table interpolation and setting the draft schedules of other stands so as to determine the distribution of the electric currents of respective driving motors to a prescribed ratio. CONSTITUTION:In a continuous cold rolling mill consisting of plural stands; the target inlet sheet-thickness of a final stand of plural ones is set by a table interpolation, and the target interstand sheet-thickness are set so as to determine the distribution of the currents of respective driving motors of said stands excluding the final one to a prescribed ratio, to decide the draft schedules. In this way, the optimum rolling speed at the final stand is decided, and also the generation of heat scratch at other rolls is prevented, to make the stable operation possible.
