Abstract
A method of hot rolling steel slabs of thin to standard thickness into hot mill band is carried out on a hot reversing mill having a coiler furnace upstream and downstream of the reversing mill. A twin stand hot reversing mill is used and the slab is introduced into the first stand of the mill without any breakdown pass. Flat passes of the slab back and forth through the first stand and the second stand occur to form an intermediate product having a thickness capable of being coiled. Thereafter, the intermediate product is coiled on one of the upstream or downstream drums. The product is then passed back and forth between the first and second stand in tandem. An edging stand is positioned between the reversing stands to edge the product during the flat passes. The final product is removed from the hot mill band in one of sheet, plate or coil form.
