Abstract
PURPOSE:To effectively reduce the amount of crop loss to be generated in the top and the bottom of slab, by giving a rolling reduction to the slab with a roll group comprising a couple of vertical rolls and a couple of horizontal rolls whose roll axes are arranged in the same plane, before feeding the slab to the final roughing pass. CONSTITUTION:The universal rolling mill 14 is installed in the same line as the hot roughing mill 7, and comprises a couple of vertical rolls 15 and a couple of horizontal rolls 16 arranged between these vertical rolls 15; hereupon, the roll axes of the vertical rolls 15 and the horizontal rolls 16 are arranged in the same plane perpendicular to the slab 6. A slab 6 is heated by the heating furnace 5 to prescribed temperatures and is fed to the universal rolling mill 14 in which the slab 6 receives a rolling reduction by the vertical rolls 15 and the horizontal rolls 16 in the directions of thickness and breadth at the same time; thereafter the slab 6 is roughed by the roughing mill 7. In the present method, it is desirable to install the universal mill 14 on the upstream side of the hot roughing mill 7 so far as circumstances permit.
