摘要： A plurality of materials are rolled in an upstream stand. While the 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. The transfer speed of the succeeding material is controlled by adjusting at least the drive speed of the pinch rolls so that the front end of the succeeding material contacts the rear end of the preceding material at a specified position in a travelling welder. 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 to form a continuous material while letting the travelling welder 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.

摘要： This apparatus has plural fixed grinding machines, which are installed along the direction of travelling line of billets. Facing pairs of grinders are equipped in a manner that the distances between each facing pair of grinders are gradually shorter along the travelling direction of the billets 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 is ground sequentially by the grinders, and the burr on welded part of the right and left side of the billet is ground sequentially by the grinders.

摘要： A method for continuous rolling includes flash-butt welding to form a continuous billet by joining a rear end of a preceding billet with a front end of a succeeding billet, removing burrs from a welded portion of the joined part, and continuously rolling the joined continuous billet in a rolling mill group. The flash-butt welding step includes the use of two travelling welders arranged in series and spaced at a distance along the direction of movement of the continuous billet corresponding to the length of the billet being welded. The travelling welders synchronously move with the continuous billet, and separately and simultaneously weld the continuous billet to another billet by flash-butt welding so as to extend the length of the continuous billet.
