The Differences Between Hot and Cold Rolled Steel ...

NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000° F.

Rolling (metalworking) - Wikipedia

Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal, like semi-finished casting products, such as slabs, blooms, and billets.

Production process

During the hot strip' process route, slabs are heated in two walking-beam furnaces and subsequently reduced in the roughing mill to a transfer bar of 27 mm which is coiled in a coil box. This coiled transfer bar is rolled in the finishing train to produce a hot rolled coil in the dimensions required by the customer.
