Abstract (en)

[origin: WO9305897A1] An intermediate billet, which has been rolled by a rough roll train of a bar rolling mill, is finish rolled to obtain N pieces of strands connected to one another through thin connecting portions. Next, strands at opposite ends are cut off at the connecting portions by slit rolls, and subsequently, strands at opposite ends out of a plurality of intermediate strands, which have not been cut off, are cut off at the connecting portions by the slit rolls. Thenceforth, the cut-off of strands at opposite ends at the connecting portions is repeated, whereby all of the strands are cut off at the connecting portions by the slit rolls, and subsequently, the strands thus cut off are simultaneously rolled, to thereby manufacture N pieces of metal bars at the same time.
