摘要： A steel-strip production apparatus 1 includes a continuous annealing furnace 2, a snout 6 connected to the continuous annealing furnace 2, a contact-type seal plate device 10 and a noncontact-type seal roll device 20 that are arranged on the entry side of the snout 6 along the transfer direction of a steel strip S in this order, a hot-dip-plating tank 5 that is movable, and an in-tank immersion sink roll 31 configured to turn the path direction of the steel strip S after passing through the snout 6. The steel-strip production apparatus includes a hot-dip-plated steel strip production unit configured to produce a hot-dip-plated steel strip by bringing the steel strip S continuously annealed in the continuous annealing furnace 2 into the hot-dip-plating tank 5, and a cold-rolled steel strip production unit configured to produce a cold-rolled steel strip by transferring the steel strip continuously annealed in the continuous annealing furnace 2 without causing the steel strip to pass through the hot-dip-plating tank 5, configured to be switchable with one another.

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.
