Abstract

PURPOSE:To manufacture efficiently rough formed billets used respectively for plural kins of H-beams, by forming a continuously cast slab of the same dimensions into a rough formed stock of specific dimensions and correcting its cross-sectional dimensions and shape by using the same forming rolls. CONSTITUTION:A continuously cast slab (a) having comparatively small thick ness and small width is edged by a 2-Hi break down mill BD, to form a dog- bone-shaped rough formed stock (d) having a web inside-dimension smaller than the minimum dimension of an aimed product dimension. The thickness of web is subjected to rolling reduction to enlarge its inside dimension and the shapes of flange parts are corrected by a 2-Hi forming mill R1 provided with plural caliber rolls for enlarging the web inside-dimension, and the inside dimension of web is enlarged in sequence as shown by (f), (g), (h) to obtain an aimed rough formed steel for an H-beam. Thereafter, the aimed H-beams (f'), (g'), (h') are obtained by the rolling of a series of universal mills U1, E1. UF.
