Jun 09, 2017· A rolling mill is the place where the rolling of steel in carried out. It consists of one or more rolling stands along with some auxiliary equipment where auxiliary operations associated with the rolling of steels are performed. Rolling of steel in small and medium sized rolling mills is generally carried out in cross-country rolling mills.
Large scale mills are required to manufacture in this way and produce large batches of profiles for their customers: typically, large mills may demand a minimum order of 100 tons per year per section for carbon steel. This is due to the important tooling costs and to the set-up of the mill for rolling the section ensuring defined tolerances.
When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon steel and stainless steels) and non-ferrous (copper, brass, lead, etc.) integrated or electric arc furnace (EAF) steel mill of today, to small manually cranked rolling devices used at jewelers to reduce the thickness of
