    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.

    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.
