    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： In a tandem mill system, at least one first type rolling mill is arranged in the upstream side and at least one second type rolling mill is arranged in the downstream side. The first type rolling mill is of the so-called work roll crossing mill in which a pair of work rolls are inclined with respect to a pair of back-up rolls supporting the work rolls and simultaneously crossed each other in a horizontal plane to control transverse thickness distribution of a strip. The second type rolling mill is of the so-called HC mill which controls the strip crown and shape by a combination of axial movement of intermediate rolls and work roll bending. Such an arrangement makes it possible to increase a capability of controlling the strip crown and shape, particularly, a capability of correcting the quarter buckle, and eliminate a fear of causing scratches on the strip and roll surfaces, with the result of improved production efficiency. Plural lines of lubricant supply device are also provided to stop supply of a lubricant immediately before biting of the strip into the work roll crossing mill and start the supply again after the biting. A system of lubricating the work roll crossing mill is thereby improved.

    摘要翻译： 在串联轧机系统中，至少一个第一类型的轧机设置在上游侧，并且至少一个第二类轧机设置在下游侧。 第一类轧机是所谓的工作轧辊交叉轧机，其中一对工作辊相对于支撑工作辊的一对支承辊倾斜，同时在水平面上彼此交叉以控制横向 条的厚度分布。 第二种轧机是所谓的HC轧机，它通过中间轧辊的轴向运动和工作辊的弯曲来组合控制带材的顶部和形状。 这样的布置使得可以增加控制带材凸厚和形状的能力，特别是修正四分之一带扣的能力，并且消除了在带材和辊表面上产生划痕的担心，结果提高了生产效率。 还提供多条润滑剂供应装置，以便在将条带咬入工作辊交叉磨机之前立即停止供应润滑剂，并在咬合之后再次开始供应。 从而提高了工作辊交叉磨机的润滑系统。
