Abstract
PURPOSE:To prevent the generation of overlapping, and to improve the yield of the bloom, by executing the rolling work after previously forming the head and bottom of the ingot into a shape of truncated pyramid or a truncated cone. CONSTITUTION:The hot ingot 1 being dragged out of the soaking pit is conveyed by the ingot car 2 and is weighed by the ingot scale 4 after passing the turntable 3. The portions 1a to be truncated later are formed in the head and bottom of the ingot 1 by the press machine 5; hereby, the truncated pyramid or truncated cone type ingot is prepared. Next, above prepared ingot is rolled by the blooming mill 6 and the billet is manufactured.
