Abstract

PURPOSE:To roll a flat steel material in the direction of breadth in order to give an excellent shape and suitable breadth to the flat steel material, by applying a rolling work on the basis of a computed value of a peak position of a dog bone formed by a rolling work ih the direction of breadth given to ghe flat steel material, and also one the basis of a computed value of the rolling load. CONSTITUTION:A material 2 to be rolled in rolled in the direction of breadth by upper and lower flanged vertical rolls 1 in order to form side edges of the material 2 into a dog bone shape. Hereupon, a peak position (l) of the dog bone is computed from the equation I. A rolling load P to be given to the material 2 at this position (l) is computed from the equation II. On the basis of this rolling load P, the vertical roll 1 applies a rolling work in the direction of breadth to the material 2, that is a flat steel material. As a result, the generation of flaws in the material 2 is prevented, and the quality and yield are improved.
