Title:
不等辺山形鋼の短辺端部の成形方法、及びその装置
Document Type and Number:
Japanese Patent JP5884498
Kind Code:
B2
Abstract:
A short-side end molding device has a molding roller (20) that, in a hot rolling step for an unequal angle steel, presses and molds an end part (201b) of the short side (201) of an unequal angle steel (200) that has undergone an intermediate rolling step or a finishing rolling step using a molding part (22), as the end part (201b) is caused to pass over the molding part (22), which is formed in an outer peripheral surface (21), in the circumferential direction of the molding part. The molding part (22) is formed in a recessed shape over the entire circumference of the outer peripheral surface (21) of the molding roller (20). The shape of the molding roller (20) along the axial direction is an arc shape and a linear shape adjacent to the arc shaped portion (22a), and the linear shaped portion (22b) matches the tangent (t) of the adjacent end part (22c) of the arc shaped portion (22a).
