摘要： A pair of upper and lower electrode wheels (1, 2) are disposed so that their axes (17, 18) are tilted in a horizontal plane in respective directions opposite to each other with respect to a straight line (Y) perpendicular to a welding line (X) defined on overlapping portions (L) of two metal plates (5, 6), and mash seam welding is performed while positively driving electric motors (61, 62). This can reduce the increased amount of thickness and step gradient of a joint portion to reduce a stress concentration factor to ensure a high degree of joint strength. The metal plates are joined to each other such that a nugget (N) is not deviated from a joint interface. The respective tilting directions of the axes (17, 18) of the electrode wheels (1, 2) are made to face in the horizontal plane toward the extending direction of a metal plate with which the electrode wheels (1, 2) first come into contact. Therefore, it is possible to prevent respective ends of the metal plates at the overlapping portions L from biting into and scratching the corresponding electrode wheels (1, 2) and to prevent the occurrence of spattering during the welding.
摘要翻译：一对上，下电极轮（1,2）被布置成使得它们的轴线（17,18）相对于垂直于焊接的直线（Y）在彼此相反的方向上在水平面内倾斜（5）的重叠部分（L）上限定线（X），并且在正向驱动电动机（61,62）的同时执行压薄滚缝焊接。这可以减小接头部分的增加的厚度和阶梯度，以减小应力集中系数以确保高度的接合强度。金属板彼此接合，使得熔核（N）不会从接合界面偏离。使电极轮（1,2）的轴（17,18）的各个倾斜方向朝向水平面朝向电极轮（1,2）首先进入的金属板的延伸方向联系。因此，可以防止重叠部分L处的金属板的相应端部咬入并刮擦相应的电极轮（1,2），并防止在焊接期间发生飞溅。

摘要： Disclosed are cold-rolled material manufacturing equipment and a cold rolling method by which a high efficiency, a high yield and a high investment cost-effectiveness are realized in a small- to medium-scale plant with a capacity of about 300,000 to 600,000 tons of product per year. A strip of a coil 101a unwound from a unwinding device 2 is guided directly to a cold rolling mill 1 to be rolled and then wound onto a winding/unwinding device 4. Upon arrival of the tail end of the coil 101a at a joining device 5, the coil 101a and the leading end of a coil 101b subsequently unwound from the unwinding device 2 are joined. Subsequently, rolling and joining for the coil 101b and following coils are repeated to perform first-pass rolling by the cold rolling mill 1 and joining by the joining device 5, thereby forming a plurality of coils into one buildup coil 102. The buildup coil 102 is subjected to reversible rolling a predetermined number of times until a desired product strip thickness is reached. In the final pass, the buildup coil 102 is cut by a cutting device 6a or 6b, to form a plurality of coils 103.

摘要： A pair of upper and lower pressure rollers (3, 4) is disposed so that their axes (15, 16) are tilted in a horizontal plane in respective directions opposite to each other with respect to a straight line perpendicular to a welding line of a joint portion J. The pressure rollers (3, 4) are positively driven by corresponding electric motors (63, 64) to thereby roll the joint portion. Thus, steps defined at the joint portion can be smoothed and a step gradient can be reduced to ensure a high degree of joint strength. The respective tilting directions of the axes (15, 16) of the pressure rollers (3, 4) are such that respective travel-directional portions (3A, 4A) of the pair of pressure rollers (3, 4) face in the horizontal plane toward the corresponding directions opposite to the extending directions of metal plates (5, 6) concerning a metal material with which the pressure rollers (3, 4) first come into contact. Thus, it is possible to prevent a step portion from being interfolded into the base material of the metal plates (5, 6). Thus, a stress concentration factor can be reduced and the steps S defined at the joint portion can be smoothed, thereby enhancing the quality of the joint portion.
