Hot rolling mill process and hot rolled steel sections

Apr 05, 2017 Hot rolling is an industrial process for reworking principally steels but also stainless steels Steelworks melt the material To make it transportable, the melted steel cools down in different shapes The process of hot rolling sections These shapes can be either blooms, billets or slabsThe Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next processThe Hot Rolling Process California SteelThere are certain types of the rolling process, whereas, in the hot rolling process, the metal is heated at its desirable temperature, when the metal is properly heated then the metal should be passed between the one or more rolling mills to gain the proper desirable shape This process is vastly used in respect of any other rolling processRolling Process: Working, Application, Defects, Type of
