Abstract

PURPOSE:To make the thickness and width of a rolling material at its outlet side constant by installing three means for detecting a horizontal work-roll pressing force, etc. and a sensor for rolling load, etc. and eliminating the variation of rolling load caused by the change of the horizontal force. CONSTITUTION:A titled equipment consists of a rolling reduction device 15 for generating a rolling down force by the change of a rolling-reduction driving body 10, a horizontal bending device 11, a rolling-reduction control device, detecting means 231-237 for detecting a pressing force to be provided to corresponding work rolls 3, 4 by said device 11 or the position of the direction of said pressing force, a load sensor 13, and a level control means 26. Said device 11 generates a bending by providing a force to the rolls 3, 4. Further, said rolling- reduction control device inputs a draft-position setting signal SR required for setting the position of body 10, and drives the device 15 so as to make the sheet thickness of a rolling material at its outlet side constant. Then an output of said means 26 is supplied to an inputting point of the signal SR to eliminate the change of rolling load.
