Abstract
PURPOSE:To eliminate a need for an exchange of guide from one to another and cut a time necessary for an alternation of product size by preparing roll pass of both series with similar passes which are in a range allowing these passes to use the same guide, in two series of bar steel mill stand having different finish pass-sizes. CONSTITUTION:In a bar steel mill having both series A, B of different finish pass- sizes, a radius of curvature of an oval pass of each stand of N, N+2 and N+4 in the A series is designed so as to have the same radius of curvature on the same stand in the B series. In case of an alternation of sizes from the A series to the B series to be made, for example, an inlet guide 1' of the stand N+1 is not needed to alter because a radius of curvature of a rolled material is the same for both series A, B, and the rolling of different products are performed by adjusting a gap l of guide to fit a gap l' alone. Further, in case of a diamond groove, the method is, also, applied in the completely same manner by replacing the radius of curvature of the oval pass with a vertical angle of the diamond groove.
