Abstract

PURPOSE:To improve the quality of a rolled product and to reduce an equipment cost and the production cost of the product by disposing a cluster rolling mill having large power to control a crown shape to the post stage of a tandem rolling mill so that high-draft rolling is permitted. CONSTITUTION:The cluster rolling mill is disposed to at least >=1 stands of the post stand of the tandem rolling mill. At least one of a pair of work rolls 2 of such cluster rolling mill is formed to have the smaller diameter and is supported by a pair of intermediate rolls 3. These rolls are further supported by plural back up rolls 4. Roll benders 71, 81 are used in combination during rolling with said cluster rolling mill to improve the capacity to control the crown shape of a metallic strip 1. Since the work rolls 2 are formed to the smaller diameter, the effects of reducing the rolling load and decreasing the edge drops of the strip 1 are multiplied.
