Abstract
Official abstract text for this publication.
In cold-rolling a steel sheet coil, when a tail end portion of a steel sheet coil ( 7 ) is wound around a tension reel ( 3 ) prior to second-pass rolling after the completion of first-pass rolling, the tail end portion is heated to a temperature within a range of not lower than 50° C. nor higher 350° C. with a heater disposed between a rolling stand ( 1 ) and the coil tail end-side tension reel ( 3 ).
First claim
Opening claim text (preview).
What is claimed is: 1. A cold-rolling facility for cold-rolling a steel sheet coil comprising: a pay-off reel from which the steel sheet coil is uncoiled; a single-stand reverse rolling mill; a first tension reel on the opposite side of the reverse rolling mill from the pay-off reel; a second tension reel on the same side of the reverse rolling mill as the pay-off reel; a deflector roll disposed between the reverse rolling mill and the second tension reel, and a heater d…
