Abstract

PURPOSE:To automatically interchange the stand whose roll caliber has worn away with another controlled stand, in order to contrive the improvement of the working rate, by arranging the detector for wear of the roll caliber and the interchanger for the stand of controlled rolling reduction, in the finishing mill for the seamless steel pipe. CONSTITUTION:In the finishing mill for the seamless steel pipe, plural units of the sizer 1 are made the controlled stand for purposing the dynamic correction, and are controlled by the temperature controller 6, the arithmetic unit 5, the rolling reduction controller 3, the driver 2, etc.; at the same time, the outer diameter G of the rolled steel pipe is detected by the detector 8, and is inputted to the outer diameter data collector 9, whose data H is given to the control-learning-arithmetic unit 10 which gives the learned amount K to above stated arithmetic unit 5. At the same time, when this value K exceeds the specified value, the data for anomalous wear of the roll is given to the controlled stand interchanger 11 through the roll wear detector 12, in order to automatically interchange this stand with the stand being provided with the same roll as that of the sizer 1; thus the controller is constituted.
