PROBLEM TO BE SOLVED: To provide a multi-function rolling mill for rolling equipment for wide flange shapes and rolling method using the multi-function rolling mill for the wide flange shapes by which the rolling mills are reduced to two, the cost of equipment is made inexpensive, the line length is shortened and the necessary length of a building is shortened by equivalent length. SOLUTION: Upper and lower roll parts 14, 15 for reducing web thickness, not only right and left rolls 16, 17 for reducing flange thickness but upper and lower roll parts 18, 19, 20, 21 for reducing flange width are integrally incorporated. And, the roll width W of the upper and lower roll parts 14, 15 for reducing the web thickness is made adjustable with screw shafts 75 for adjusting the roll width and also the upper and lower roll parts 18, 19, 20, 21 for reducing the flange width are made movable between the reduction position and the retreat position with eccentric rings. |
