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