Steel is made in steel melting shop in the refractory lined vessels called LD Converters by blowing oxygen through the hot metal bath. While iron making is a reduction process, steel making is an oxidation process. The oxygen reacts with impurities like carbon, silicon, phosphorous, sulphur etc. present in hot metal to produce steel. No external fuel is required as the silicon & carbon releases huge amount of heat energy.Also the carbon reaction releases large quantities of gas rich in carbon monoxide along with huge amount of dust.
Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands. According to this, the profiles are performed through a series of passes. This is allowing a high design flexibility. Furthermore, the rolls of the stands have a particular shape for the specific step within the rolling process. So the final shape of the profile determinates the amount of stands. They are needed for transforming the large raw material block into the smaller section.
Heat treatment is the process of heating metal without letting it reach its molten, or melting, stage, and then cooling the metal in a controlled way to select desired mechanical properties. Heat treatment is used to either make metal stronger or more malleable, more resistant to abrasion or more ductile.
