Abstract
PURPOSE:To prevent the defective convex roll mark to be printed on the strip by the work roll during the cold rolling work at a high rolling reduction, by specifying the hardness of the intermediate roll to be arranged in the multiroll mill, and by applying the dulling work to this intermediate roll. CONSTITUTION:In the five or more-high multiroll mill, the roll of 72-75 degrees Shore hardness is employed for the intermediate roll to be built in the mill, and the dulling work is applied to this intermediate roll's surface. Hereby, even if the contact pressure between the intermediate roll 2 and the work roll 1 in the cold rolling work at a high rolling reduction increases to an extent of 1.2TON/mm., the generation of the dent flaw in the work roll 1 to be caused by the scum, etc., is prevented; as a result, the defective convex roll mark to be formed in the rolled strip can be prevented.
