| 摘要 |
This invention relates to a rolling mill apparatus and process which utilizes the creation of a differential friction force in at least the most downstream one of a plurality of roll bites for a variety of purposes. In a first embodiment, a differential friction force is created at the most downstream roll bite for reducing the maximum strip tension and forward strip tension thereby increasing the maximum attainable reduction in strip thickness per pass and reducing the size of the recoiler used for applying the forward tension. In a second embodiment, differential friction forces are created at the most upstream roll bite and the most downstream roll bite for increasing strip tension at all of the roll bites while decreasing the separating force required to obtain given strip reductions without increasing the maximum strip tension.
