The process of hot rolling steel starts with a billet of metal, which is a thick, long sheet. This billet is heated, followed by being flattened into a roll. The billet remains heated as it is sent through a group of rollers to give it an ideal shape. For hot rolling sheet metal, the steel is rolled into coils and then left alone to cool down.
