    摘要： In a continuous hot rolling system, at least one melt-cut torch (6) is set in a predetermined positional relationship with respect to a trailing end of a preceding hot material (1) and a leading end of an adjacent succeeding hot material (2). An injected flow of cutting gas from the melt-cut torch (6) is blown against at least one of the ends to melt-cut the portion. The ends of the materials are forced against each other and are butt-joined to each other. Joining may be made with respect to slabs before rough rolling, or may be made with respect to bars after rough rolling. A slab manufactured by a continuous casting machine is reduced in thickness at a plurality of desired portions. Cutting and joining is made at these portions. Furthermore, the ends, after having been cut, are reduced in thickness with the ends abutted against each other to form thickness-reduced portions. These portions are joined to each other.

    摘要： When a strip (2) of e.g. hot steel is rolled by a rolling or roughing mill, scale develops on the surface of the strip (2) which must be removed. The strip (2) is passed over a bending roller (5) which bends the strip (2) and causes cracks in the scale. Then water is injected (11) on to the strip (2) to wash the roller (5) to lift off the scale. Inertia then causes the water and scale to leave the surface of the strip (2) and pass to a collection means (12) whose water collecting surface (14) is out of contact with the strip (2) and on the opposite side of the bending roller (5) from the water injection (11). In this way the time of contact of the water with the strip can be kept short and the strip is not damaged by contact with the collection means (12). A further bending roller (6), water injection means (15), and collection means (16) may be provided to remove scale from the other side of the strip (2).

    摘要： Methods and apparatus for joining conveyed steel pieces in a hot rolling mill are disclosed. A joining apparatus having a series of fusing torches (6) extending laterally across the steel path is used, either before a rough rolling stage or between rough rolling and finish rolling. The fusing torches (6) which operate at the side edges of the pieces to be joined are controlled to have independent movement by a controller (37), in such a way that the time elapsing between fusing and pressing together of portions at the lateral edges of the join line does not exceed a critical time for regrowth of oxide scale. Various mounting and control techniques for the fusing torches (6) are proposed, including the possibility of two independently-driveable sets (8,8a) the controller can base its control of the torches (6) on steel strip width information obtained from the processing path.
