EQUIPMENT FOR MANUFACTURING A COLD-ROLLED MATERIAL, AND COLD-ROLLING METHOD

Document Type and Number:

WIPO Patent Application WO/2011/074080

Kind Code:

A1

Abstract:

For a small-to-mid-sized production facility with an annual output between around 300,000 and 600,000 metric tons, the disclosed cold-rolling equipment and method provided an excellent ROI while maintaining high efficiency and yield. Input coils (101a to 101c) paid out from a pay-out device (2) are spliced together by a splicing device (5), a build-up coil (102) having a diameter of 3000 mm or less is formed at a take-up/pay-out device (6), and the build-up coil (102) is reversibly cold-rolled a prescribed number of times by a cold-rolling mill (1) between take-up/pay-out devices (3 and 4) until a desired product thickness is reached. On the last pass, while being slow-rolled (for example at 2 mpm) by the cold-rolling mill (1), the build-up coil (102) is segmented by a segmentation device (7a or 7b), thereby forming a plurality of output coils (103a to 103c) that are extracted from the take-up/pay-out device (3) and carried out.
