Metal strip continuous line stripping control method and metal strip continuous line

摘要

PROBLEM TO BE SOLVED: To wind a metal strip and accelerate the tension reel, and when deceleration or stop of the metal strip occurs at the center of the line, the winding speed of the tension reel conflicts with the speed limit and the metal strip is wound. Provided is a technique capable of avoiding a sudden deceleration of the speed. SOLUTION: When the winding speed of the tension reel is increased to reach the continuous line exit side set speed, the speed limit of the tension reel is set when there is a deceleration at the center of the continuous line or a stop of the continuous line. When the difference between the speed limit and the winding speed of the tension reel falls below a predetermined threshold value, the tension reel The winding speed is held constant, and when the reduced speed limit and the held winding speed match, the holding of the winding speed is released, and the tension reel winding speed is decelerated according to the speed limit.
