A high rigidity drive system application in the control of the reducing and sizing block

The reducing and sizing block technology represents modern equipment of high speed bar and wire rod mill.It puts forward higher requirements for the electrical control system,which is a high rigidity drive system with small dynamic speed drop and short recovery time.CERISTAR Electric Co.,Ltd.implements a high rigidity drive system with load observer in two ways,using a pre-controlled speed or a pre-controlled torque.This scheme has actually applied on the KOCKS mill in an alloy steel rolling rod production line.The rod production shows good quality.And the users give a very high evaluation to this production line.
