FLOW STOP CONTROL METHOD FOR CASTING WITHDRAWAL CONTROL OF HORIZONTAL CONTINUOUS CASTING MACHINE

摘要

In a horizontal continuous casting machine having a casting withdrawing cycle consisting of withdrawing, stopping and push-back periods, a method of controlling the stop of the flow of a casting during the stopping period of the withdrawing cycle so as to stop the flow of the casting within a predetermined period. The desired braking torque is calculated in consideration of the load variations due to the casting condition of the horizontal continious casting machine and the braking torque is applied to the pinch roll shafts upon the termination of the withdrawing period thereby effecting the stop of the flow of the casting during the stopping period within the predetermined time.
