| 摘要 |
The invention is aimed at enlarging the production range of an installation for the cold rolling of metal strip, incorporating at least two rolling cages (L1, L2) operating in tandem. At least one of the cages (L1) is equipped with a transformation means allowing the configuration of the cage to be changed, whilst conserving the same means for the application of the rolling effort, in a manner to arrange at least two configurations each corresponding to a production range. The configuration of the transformable cage is chosen as a function of the characteristics of the product to be rolled, the production range being thus enlarged. An Independent claim is also included for a rolling mill installation for putting this method of enlarging the production range into service. |
