Abstract

PURPOSE:To greatly increase the alterability of breadth of the salb, by installing a couple of horizontal rolls and a couple of specially shaped, combined work rolls on the upstream side of the hot roughing mill. CONSTITUTION:A slab 5 is heated to described temperatures by the heating furnace 4, and is fed to a couple of combined work rolls 11 provided with a box caliber and one or more annular projections. The box caliber of this combined work roll 11 is assigned to the edging work for the slab 5, and the annular projections are assigned to the broadside rolling work. Required number of passes of said edging work and broadside rolling work is respectively applied to the slab 5 in a reverse rolling method. Then, the slab 5 is rolled by the horizontal rolls 10 through a required number of passes, and following to it, the slab 5 is passed through the hot roughing mill 6, the crap shear 7 and the hot finishing mill 8 in this order, and is coiled by the coiler 9.
