Abstract

PURPOSE:To obtain products of steel bar and wire rod having high dimensional accuracies, by calculating the deviation between the dimensions in the width direction of a material to be rolled at the inlet and outlet sides of a stand, and adjusting the deviation to a prescribed value by controlling the rolling loads at said stand and a stand prior to it. CONSTITUTION:A rolling load at the (i-1)th stand is detected by a load detector 21, and its detecting signal is fetched to a calculator 10 through a delay circuit 6 to calculate the dimension in the direction of rolling reduction at the outlet side of the (i-1)th stand. Further, the calculator 10 calculates simultaneously a rolling load at the (i)th stand so that the deviation DELTAHi between the dimensions in the width direction at the inlet side of the (i)th stand and the dimension at its outlet side satisfies a prescribed value alpha, and adds a control signal with which said rolling load is obtained to a rolling reduction controlling device 42 of the (i)th stand. Next, the device 42 drives a rolling reduction device 32 to control a roll gap.
