CASTING METHOD OF MANUFACTURING A STEEL STRIP WITH A TWIN ROLL, CAPABLE OF REDUCING THE CASTING THICKNESS CHANGE WIDTH ACCORDING TO THE ROTATION CYCLE OF A CASTING ROLL

摘要

PURPOSE: A casting method of manufacturing a steel strip with a twin roll is provided to increase an error rate and to reduce the casting thickness change width according to the rotation cycle of a casting roll.;CONSTITUTION: A casting method of manufacturing a steel strip with a twin roll comprises next steps. The casting thickness variation is reduced by making the phase difference between the fixed roll and a moving roll by differently controlling the rotation speed of the fixed roll and moving roll in an initial casing step. The rotation speed of the moving roll is normalized as 60m/min after raising 58m/min for 1 minute.;COPYRIGHT KIPO 2011
