The halfproducts are then fed to cold reduction mills. The metal is rolled to the thickness of mm in case of mild steel and mm in case of stainless steel. The material is cooled by the use of oil which also acts as a lubricant during the rolling process. As the metal sheet gets thinner between the rolls, its speed increases.

There 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 process.

11/09/2014· Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes.

Rolling starts with blooms that may be 150 millimetres by 200 millimetres by 5 metres long. The blooms are received, either cold or hot, directly from the blooming mill or continuous caster. They are charged into a pusher or walkingbeam continuous furnace and heated for up to three hours to 1,200° C.
