The present invention is a method and apparatus for the production of thin metal strip by the hot rolling process. Significant improvements in the finished products can be made by the arrangement of the apparatus and the method of the present invention. The apparatus of the present invention is a metal processing line having a roughing reversing mill stand and a finishing reversing mill stand, each with different sized working rolls. A heating furnace precedes each mill stand. The apparatus in the present invention has the advantages of producing desired thin metal strip in the thickness range of about 0.4 to about 1.2 mm at temperatures appropriate for the specific metal being rolled.

[ What is claimed is:] [1.] A hot-rolling process for producing thin metal strip comprising:heating a metal slab of an initial thickness to a first temperature suitable for rolling in a roughing mill;rolling the resultant heated slab of said initial thickness in at least one roughing reversing mill stand having work rolls of a first diameter to produce a strip of an intermediate thickness;re-heating said strip of said intermediate thickness to a second temperature suitable for working in a finishing mill, said second temperature being less than said first temperature; androlling said strip of said intermediate thickness in a finishing mill having at least one finishing reversing mill stand having work rolls of a second diameter, less than the first diameter of said work rolls of said at least one roughing reversing mill stand, to produce a strip of a final thickness of about 0.4 mm to about 1.2 mm.
