Abstract

PURPOSE: To perform rolling at ordinary prescribed rolling speeds on outlets side even while the mills of specific stages are not in operation by using electric motors operating at the prescribed driving speeds under sharing of rolling load in the max. longest period where the stop of operation if forecast as driving sources for stands.
CONSTITUTION: For example, as driving sources for tandem mills 21W25 of 5- stage stands, electric motors withstanding overloading for 2 hours at 125% are used. At the stage of changing the 5th stand 25, the entire rolling load is shared by the 1stW4th stands 21W24, and the rolling is continued at the speed equal to the max. rolling speed of the 5-stage stands. Hence, working performance is improved without requiring the stopping of the line during roll changing. When the specific stand stops on account of a fault, it is handled in the similar manner.
