Hot rolled steel is the most basic form of carbon steel product produced by the steel mill and is applied to appliions where surface finish is not critical. The process to create hot rolled steel begins with heating slabs of steel to a high temperature. When the hot material is transferred from the furnace it reacts with the oxygen in the air.
26/10/2021 · The roller mills apply force to the top and bottom of the slab. They continue to do so until the slab reaches the desired thickness. Depending on the final thickness of the aluminum, the resulting product will be classified in one of three ways, as defined by the Aluminum Association .
