PROBLEM TO BE SOLVED: To provide a bend correction method that enables a bend of shape steel to be efficiently removed by imparting a proper rolling load.SOLUTION: A relational expression between a rolling load applied to a flange and the amount of change of a bent of H-shaped steel, which is caused by rolling applying the rolling load, is predetermined. When the H-shaped steel (shape steel to be corrected) with the bend is subjected to bend correction, the rolling load required to correct the bend of the shape steel to be corrected is calculated by using the relational expression. The calculated rolling load is applied to the flange and rolled so that the shape steel to be corrected can be subjected to the bend correction. |
