In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products ( reinforcement bars, steel plates) only require hotrolling, some others may require both hot– and cold ...
