摘要

Roll stand for production of rolled strip (1) including working rolls (10,11,15,16), supported on backing rolls (30, 31) or intermediate rolls (20,21), or both of these rolls. The body length of of each intermediate roll, in a 6-high or each working roll in a 4-high stand consists of a cylindrical roll body section and a convex curved section, where the transition point (A) from cylindrical to curved rolls can be selected withen the region L/2less than x less than L.
