PURPOSE:To correct offset of the web center or to prevent the generation of that by guiding a rolled stock with high accuracy to a universal mill for rolling shapes. CONSTITUTION:Plural guide rolls 6-1, 6-2, 7-1, 7-2 with which the end parts of flange of the rolled stock 1-1 are guided are zigzag arranged and also guide rolls 10, 11 for end part of flange are arranged in symmetric upper and lower positions on the axis of the pass line C just near the rolling mill. After bend of the rolled stock is straightened with the guide rolls which are zigzag arranged, the rolled stock is guided with the guide rolls 10, 11 for end part of flange just near the rolling mill so that the center line C1 of the flange width of the rolled stock is made to coincide with the pass line C2, the position of web is forcibly made to coincide with the center line C1 of the flange width with the rolling mill and the highly accurate H-shape steel without offset of the web center can be manufactured. |
