摘要： A horizontal roll guide device HG or a friction guide device FG is disposed in front, and in the proximity, of a finish universal mill FU of a rolling process of a shape steel having a flange and a web so as to restrict the center portion of the web in the transverse direction, the finish universal mill includes barrel width-variable horizontal rolls 1a and 1b, and axes XV of vertical rolls 2a and 2b are moved by a distance d on the entry side of the rolling direction relatively to the axes XH of the barrel width-variable horizontal rolls 1a and 1b to as to restrict the web. Due to the synergistic effect of these two restriction effects, web curving and web off-center of the web when the web of the shape steel is rolled from axial direction by the vertical rolls 2a and 2b by setting the roll width of the barrel width-variable horizontal rolls can be restricted. Accordingly, a variety of shape steels having a flange and various web heights can be produced very accurately.
