摘要： [Problem] To realize efficient and stable production of a steel H-beam product having a greater flange width than conventional products, and to avoid producing defective shapes during a shaping operation using flat shaping grooves in a rough rolling step. [Solution] A rolling machine that carries out the rough rolling step has engraved therein a plurality (five or more) of grooves for shaping a material to be rolled. These grooves are used to carry out single- or multi-pass shaping of the material to be rolled. A protruding section for forming a cut in a direction perpendicular to the width direction of the material to be rolled is formed in a first groove and a second groove among the plurality of grooves. At the second groove and the grooves subsequent thereto among the plurality of grooves, reduction in pressure is carried out in the shaping performed in one or more passes while the edge surface of the material to be rolled and the groove peripheral surface are in contact with each other. At a third groove and the grooves subsequent thereto but excluding the final groove among the plurality of grooves, a step is performed for sequentially bending split parts formed by the cut. The final groove among the plurality of grooves is of a flat-shape type, and the roll shaping by the flat-shape groove is conducted under a condition in which the pull-down rate is 1.0 or lower.

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.
