METHOD FOR CONTROLLING TORQUE BALANCE OF DRAWING-OUT ROLL FOR CAST SLAB IN CONTINUOUS CASTING EQUIPMENT, DETECTION OF SLIPPAGE AND DEVICE FOR CONTROLLING TORQUE BALANCE

摘要

PURPOSE: To obtain a cast slab having high quality by preventing the slippage of drawing-out rolls with respect to the cast slab in continuous casting equipment. ;CONSTITUTION: A slippage monitor means 27 extracts a prescribed signal from a driving control means 10 which can individually control the rotating speed of each drawing roll 7a to monitor the presence of slippage. At the time of detecting the slippage, a rolling reduction force control device 26 controls the rolling reduction means 25 based on the driving signal outputted from the slippage monitor means 27 and the rolling reduction force of the drawing-out roll 7a developing the slippage is raised.;COPYRIGHT: (C)1995,JPO
