    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).

    摘要： An apparatus for joining billets in continuous rolling mill comprises a pair of parallel rails 14, a travelling welding machine 4 having first support rolls 54,55, a travelling grinding machine 5 having second support rolls 56a, 56b,57, a first group of carriages 41,42,43 each of which has a third support roll 51,52,53 for support billets, and a second group of carriages 44,45,46 each of which has a fourth support roll 58,59,60 for support billets. The travelling welding machine welds a rear end of a preceding billet with a front end of a succeeding billet while moving on the pair of rails. The travelling grinding machine removes burr on weld zone of the billets while moving on the pair of rails. The first group of carriages is arranged at upstream of the travelling welding machine and is connected with the travelling welding machine by a flexible joint member. The second group of carriages is arranged at downstream of the travelling grinding machine and is connected with the travelling grinding machine by a flexible joint member.

    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.
