Abstract

Continuously cast thin slab ingots are coiled, cut, uncoiled and rolled down to thin strip material. For a single casting line a single back and forth rolling stand is used; multiple continuous casting lines can service a single unidirectional rolling mill. The rolling temperature is attained by heat retention in the coils.
