摘要： A method of rolling raw materials inclusive of slabs for the manufacture of beam blanks, and a roll to be used therefor, are disclosed. This method includes the steps of (a) subjecting a raw material, whose section consists of a web portion and a flange portion(s) having a width wider than the thickness of the web portion, to such a partial rolling that the web portion is partially rolled at regions inclusive of at least the joints of the flange portion(s), except the remaining central region, among a plurality of regions divided in the widthwise direction of the web portion, and (b) subjecting only the remaining central regions to a rolling. In the practice of this method, there is used a roll consisting of a single cylindrical drum including a first segment and a second segment arranged side by side to each other; the first segment having at least one relief of circumferential grooves facing the web portion; a plurality of rolling collars separated apart from each other through the relief in the axial direction, and serving for the partial rolling of the web portion, and a circumferential groove(s) dividing a side of the rolling collar for the web portion near the joint and enclosing the flange portion; and the second segment having a pair of reliefs each composed of a wider circumferential groove facing the flange portion, and a rolling drum extending between the reliefs and serving for the rolling of only the remaining central region of the web portion.
