Title:
COLD ROLLING APPARATUS AND METHOD FOR COLD ROLLING
Document Type and Number:
WIPO Patent Application WO/2011/055458
Kind Code:
A1
Abstract:
An apparatus and method of cold rolling for a small sized or medium-sized plant with a capacity from 300thousand to 600 thousand tons of product per year are proposed that have a high efficiency, a high yield and a high cost-efficiency. A strip is directly fed to a cold rolling mill (1) from a coil (101a) at an uncoiler (2) to be cold-milled and then to be rewound by a rewinder (4). When the trailing end of the coil (101a) reaches a splicer (5), the end is joined to a leading end of next coil (101b) uncoiled by the uncoiler(2) and the next coil (101b) is cold-milled. The cold-milling and joining operations are repeated for following coils at the cold rolling mill (1) and the splicer (5) in a first path to form a buildup coil (102). The buildup coil (102) is then repeatedly rolled down in a reversing rolling to a desired thickness. In the final path, the build up coil (102) is divided into several coils (103) by means of a cutter (6a) or (6b).
