Embodiment Construction
[0017] According to the target temperature of strip steel finish rolling exit (less than 830°C) and finished product thickness (greater than 7mm), it is used as a selection mark to complete the corresponding high-strength steel judgment process; and then complete the logic chain function according to the strip steel tracking signal, so as to satisfy the looper Automatic control requirements.
[0018] Under normal circumstances, the looper control between the racks after the looper is set is torque control, which can solve the technical control problem of looper adjustment. For high-strength steel looper control, the variable coefficient looper automatic control is realized by computer. By changing the coefficient C of the looper torque regulator, the control matching between the looper regulator control and the hydraulic looper system is realized, which meets the requirements of strip steel. Control process requirements. Through calculation and actual debugging, the control p...
