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 burrs therefrom. After removing the burrs, the continuous material is continuously rolled by a down-stream stand.

摘要： A continuous rolling method includes the steps of: de-scaling billets sent directly from a continuous casting machine; continuously welding the billets using a travelling flash butt welder; grinding a burr on a welded part of the billets to remove the burr using a travelling grinding machine; heating the billets to an elevated temperature using an induction heater; and conducting continuous rolling. The travelling flash butt welder and the travelling grinding machine are separately movable along a running line of the billets, and are moved together during flash butt welding. The flash butt welding is carried out while the flash butt welder and the grinding machine travel a specified stroke for welding. The travelling grinding machine and the travelling flash butt welder are moved together to meet the welded part of each of the billets, and the travelling flash butt welder is returned to a waiting position after the flash butt welding is completed. The burr on the welded part of each of the billets is removed while the travelling grinding machine independently changes travelling direction and travels a specified stroke, after the welded part arrives at a specified position.
