Abstract

PURPOSE:To produce the slabs of various compositions of arbitrary widths without decreasing the yield at the rolling in the later process by combining the continuous casting machine provided with an electromagnetic stirrer along both longer sides of the slab mold of rounded inside circumference and the width-changing rolling mill which performs broadside screw-down through utilization of casting heat. CONSTITUTION:A slab mold 1 of rounded inside circumference consists of the electromagnetic stirrer 3 disposed along its longer sides 2. The slab 7 from the mold 1 goes through a continuous casting machine 5 and is heated in a recuperator 8, after which it is introduced into a broadside screw-down rolling mill 6, thence it is treated by horizontal rolls 9. According to this method, the horizontal sectional shape of the mold is rounded to the form suited for giving horizontal rotating flow and therefore even if edging of the slab 7 is done, the horizontal sectional shape of the slab does not become excessive dog-bone shape. Even if this slab 7 is supplied to the hot rolling of the later process, the occurrence of fishtails becomes minimum and the decrease in the yield which accompanies with the broadside screw-down becomes minimum.
