摘要

Billets 10 which were continuously cast in a continuous casting machine 1 are directly supplied to the joining line 12. The scale on the billets is removed by the de-scaling apparatus 3. Then the rear end of the preceding billet is welded with the front end of the succeeding billet using a travelling flash butt welder 4 to produce a continuous billet. The burr on the welded part 15 is removed by the grinders 51-53 in the travelling burr-removing apparatus 5. The continuous billet is heated in an induction heater 6, then is continuously rolled in the rolling mill line.
