Abstract

PURPOSE:To roll the captioned products of good quality efficiently from rectangular slabs by using the roll set which specifies the taper of the upper flange portion of the material to be rolled in an edge shear rolling mill and rolling the material within the specific difference range of the mean drafts of the flange and web in universal rolling. CONSTITUTION:The rough-shape slab obtained through rolling of a rectangular slab in a break-down rolling mill 1 is subjected to two-way rolling of plural passes in the (u) rolling mill set 2 consisting of a universal (U) rolling mill 3 and an edge shear rolling mill 4, whereby it is made to an intermediate product. In the rolling mills 3, 4, the hole die widths for molding and the angles that the taper of the inner side portion of the upper flange and the perpendicular upper line in the web perpendicular line assume are made respectively equal. The roll set having the upper roll shape wherein the perpendicular upward forming angle of the upper flange portion of the upper roll making contact with the upper flange of the material to be rolled is made 40 to 105 deg. and the angle that the taper on the upper flange inner side and the perpendicular line in the web perpendicular upper direction assume is made 15-35 deg. is used for the rolling mill 4. Further, in the rolling mill 3, the rolling is done in a 1-6% range of the mean drafts difference of the flange and web.
