Abstract

PURPOSE:To effectively prevent the upward and downward cambers of the material, and to prevent the surrounding installation from breakage and the material itself from being injured, by changing the specified pass of the horizontal roll pass line when the material's camber is detected, in operating the universal roughing mill. CONSTITUTION:The rolling condition like as the roll gap, etc., is previously inputted to the arithmetic memory unit 55, and its command is transmitted to the automatic position controller 51 in order to give a signal to the motor 52 for vertically moving the horizontal roll 4. The position of the horizontal roll 4 is detected by the synchro 53, and its signal is inputted to the controller 51 as feedback through the A/D converter 54. When the material's camber is detected in the specified pass, the digital switch 10 sets the number of this specified pass, and the digital switch 11 sets the pass line variation and the changing direction; and the motor 52 is driven by a specified extent at the specified pass, and the horizontal roll 4 is transferred for changing the pass line.
