twin roll casting roll of sheet metal repulsion in the casting process and speed control methods

摘要

The present invention is a constant role in the repulsion between the twin roll strip casting process, two casting rolls while performing the reaction force control method and roll roll roll cheokgaep / rate control method for controlling a constant cheokgaep for holding, due to a foreign substance introduced between the two casting rolls, such as the skull of the roll cheokgaep whether a change occurs above a certain level detect and, when the roll change has occurred more than a certain level of cheokgaep roll cheokgaep / rate control method for controlling a roll cheokgaep abnormal cheokgaep roll as feedback is interrupted, the flowing out of the material is completely out of the casting rolls and the repulsive force cheokgaep Roll change is detected, whether that is a certain level or less, and if the change in the roll cheokgaep occur below a certain level, the switching control method of the twin roll strip casting process of the cylinder casting rolls in a roll on the roll reaction force control method cheokgaep control method by cheokgaep to be restored to the original condition, restored to its original position when the roll cheokgaep, twin roll by switching to the normal control methods to control the roll repulsive force control method and roll cheokgaep / speed control method of casting roll cylinder of the strip casting process, which cast to provide a constant, while maintaining the thickness of the thin plate pairs to prevent damage to the casting rolls at the same time rolls in a roll type strip casting process reaction force control method and roll cheokgaep / rate control method.
