Title:
冷間圧延材製造設備および冷間圧延方法
Document Type and Number:
Japanese Patent JP4864172
Kind Code:
B2
Abstract:
Disclosed are cold-rolled material manufacturing equipment and a cold rolling method by which a high investment cost-effectiveness is realized while maintaining a high efficiency and a high yield in a small- to medium-scale plant with a capacity of about 300,000 to 600,000 tons of product per year. Input coils 101a to 101c unwound from a unwinding device 2 are joined together by a joining device 5, a buildup coil 102 having an outside diameter of not more than ¦3000 is formed at a winding/unwinding device 6, and the buildup coil 102 is subjected to reversible cold rolling a predetermined number of times by a cold rolling mill 1 between winding/unwinding devices 3 and 4 until a desired product strip thickness is reached. In the final pass, while being rolled at a slow speed for example, 2 mpm by the cold rolling mill 1, the buildup coil 102 is cut up by a cutting device 7a or 7b, thereby forming a plurality of output coils 103a to 103c, which are extracted from the winding/unwinding device 3 and carried out.
