TENSION CONTROL DEVICE FOR A COLD ROLLED STEEL SHEET WHICH COMPENSATES LOSS OF TENSION BY PASSING A PINCH ROLL THROUGH A TENSION LEVELER

摘要

PURPOSE: A tension control device for a cold rolled steel sheet is provided to prevent overlap and buckle of sheets by balancing the tension of a strip with a pinch roll.;CONSTITUTION: A tension control device for a cold rolled steel sheet comprises a pinch roll(20) which supports a strip and ascends and descends between inlet side bridle rolls to adjust tension, and a position control member(50) which moves the pinch roll up and down. The pinch roll compensates the loss of tension while passing through a tension leveler. The position control member comprises a slider(52), a screw jack(54), a support frame(56), and a drive motor(58). The slider supports a rotary shaft of the pinch roll. The screw jack is fitted with a screw axis for moving the slider up and down.;COPYRIGHT KIPO 2010
