摘要： A plurality of materials are rolled in an upstream stand (10). While transfer speed of a succeeding material and the front end position thereof are detected, the transfer speed and the rear end position of a preceding material are detected by a measuring roll (28). The transfer speed of the succeeding material is controlled by adjusting at least the drive speed of the pinch rolls (27) so as the front end of the succeeding material to contact with the rear end of the preceding material at a specified position in a travelling welder (24). The rear end of the preceding material is joined with the front end of the succeeding material by flash-butt welding using the travelling welder (24) to form a continuous material while letting the travelling welder (24) move at a speed synchronous with the transfer speed of the continuous material. The welded portion on the continuous material is ground and/or cut to remove burr therefrom. After removing the burr, the continuous material is continuously rolled by a down-stream stand (11), and apparatus for carrying out the above-described method.

摘要： This apparatus has plural fixed grinding machines (10,11), which are installed along the direction of travelling line of billets (1). And, facing pair of grinders (3,4) are equipped in a manner that the distances between each facing pair of grinders (3,4) are gradually shorter along the travelling direction of the billets (1) from the upstream side to the downstream side. In such a multiple-stage grinding machine, the burr on the welded part of the top and bottom side of the billet (1) are ground sequentially by the grinders (3,4), and the burr on welded part of the right and left side of the billet are ground sequencially by the grinders (3,4).
