ABSTRACT:
The present invention is a method and apparatus for the production of both discrete metal plate and coiled metal plate products. In a mill having at least two in-line reversing plate mill stands, a reheated slab can be rolled on a first reversing plate mill in several reversing flat passes. The rolled product can then be sent to a second in-line reversing plate mill for additional rolling followed by winding in a downstream coiler. In the present invention, while the rolled product is sent to the second reversing plate mill, a virgin reheated slab can be introduced and rolled on the first reversing plate mill in several reversing flat passes. This product, subsequent to a slab which is rolled and sent to the second reversing plate mill, can be sent upstream along runout tables for further processing in finishing equipment. When the first reversing plate mill is again clear of rolled product, another virgin reheated slab can be introduced to the first mill and the above process can be repeated. By this method and apparatus, at least two reversing plate mill stands can be operated to produce both discrete metal plate product and coiled metal product.
