Research and Improvement of Slab Slipping Problem at the Entrance of Widening Machine
According to the problem of slippage of the width sizing machine in the hot rolling line 2050,optimization of the anti-slip procedure of the width sizing machine is adopted,by adding the comparison procedure of the guide rolls of the width sizing machine,formulating the standard billet and the calibration standard,inputting the measured deviation of the width sizing machine during the fixing and repairing period into the control program to make comparison and correction,and comparing the actual dimensions of the repaired billet with the dimensions recorded in the corresponding system,and inputting the deviation coefficients of the deviation to the control system.Eliminate the deviation between the equipment action and the field clearance,adjust the value of the short stroke of the inlet side guide plate and the pressure value of the pinch roller,optimize the field testing conditions,adjust the automatic trimming coefficient of slab thickness and other measures to solve the problem of steel jamming in the width setting machine and improve the production efficiency.
