Abstract

PURPOSE:To prevent the fishtail formed at the broadside rolling and make the scale of rolling equipment and buildings smaller by disposing a pressing machine between the broadside rolling mills and horizontal rolling mills. CONSTITUTION:The slab 1 conveyed from a heating furnace 1 passes the broadside rolling mills 12 with opened rolls 18, 18', and its leading end is taper-worked to a predetermined rate by the pressing tools 14, 14' of a pressing machine 10. When the slab 1 is next moved to the state of a slab 6, the trailing end part is taper-worked. Next, the rolls 18, 18' of the broadside rolling mills 12 are set to predetermined screw-down positions and the slab 6 having been taper-formed at both end parts is reverse-fed and is subjected to predetermined broad-side screw-down by a reversible system. Thence, it undergoes predetermined rolling in the horizontal rolling mills 13. With this equipment, the formation of fishtail is prevented, and the yield of rolling is improved.
