ABSTRACT:
A method of continuous rolling comprises the steps of: forming a continuous billet 20 by joining a rear end of preceding billet 21 with a front end of succeeding billet 21 by flash-butt welding 3; removing burr on welded portions of the continuous billets 20; then rolling the continuous billet 20 in a rolling mill line 6; wherein locally cold portions produced by clamping at welding are reheated after removing the burr using a travelling induction-heating unit 5 running at a speed synchronously with a running speed of the continuous billet 20, which travelling induction-heating unit 5 is provided with induction-heating coils arranged at the same distance with that of the locally cold portions.
