Abstract
PURPOSE:To uniformly polish outside and inside surfaces of steel pipe, and to improve the yield, by detecting the reaction force of the plug polishing inside surface of steel pipe and the roughness of outside surface, and by controlling the rolling reduction of main roll depending on the deviation of above detected value from the aim value. CONSTITUTION:The reaction force of the plug 1 polishing the steel pipe A is detected by the load cell 22. Hereupon, the temperature of steel pipe A is detected by the sensor 24, and the detecting signal for the reaction force of plug 1 is compensated by the temperature compensating circuit 23. This temperature compensating signal is taken as the feedback signal for the plug's reaction force controller 25. Then the controller 25 compares this feedback signal with the aim value, and produces the control signal to the screw-down devices 6, 7, so as to make minimum the deviation between above two values. Meanwhile, the roughness of outside surface is detected by the detector 26, and the detected value is taken as the feedback signal for the roughness controller 27, which then produces the control signal to the screw-down devices 6, 7, so as to make minimum the deviation of the roughness of outside surface from the aim value; and hereby, the rolling reduction of main rolls 4, 5, is controlled.
