Abstract
The method of processing soft metal slabs to strip thickness on a processing line including providing a hot reversing mill having coiler furnaces on either side thereof along the processing line; heating the slab to a hot working temperature; passing the heated slab through the hot reversing mill at least one time to reduce the thickness thereof to form an intermediate product of a coilable thickness; coiling the intermediate product in one of the coiler furnaces; passing the intermediate product back and forth through said hot reversing mill and between the coiler furnaces to reduce the intermediate product to a product having a strip thickness; processing the product of strip thickness through a quench; and surface cleaning the quenched product. No subsequent hot rolling, hot milling, cold reduction or anneal takes place prior to forming the product of strip thickness.
