PURPOSE:To promote labor-saving, high efficiency and high quality, in continuous strip-making, by arranging a recoiler, a water cooler, a condition-rolling mill and a precise detector at the back of a continuous box-annealing oven. CONSTITUTION:After a cold-rolled steel strip is annealed under an opened coil condition, the steel strip is carried to a recoiler 5 by a coil truck 2 and then uncoiled. Thereafter, the strip is welded to the preceding strip S by a welder 6, and rapidly cooled to a temperature to enable condition-rolling by a water cooler 8. The strip is then condition-rolled by a condition-rolling mill 11, carried through a trimmer 12, an oil applicator 13, a detector 14, a shearer 15, etc. to a coiler 16 and coiled. Due to this mechanism, a coil-handling number in a continuous strip-making line by continuous box-annealing is lowered, and the cost of installation is also lowered. |
