Hot rolling of steel:

Hot rolling of steel is the metallurgical process when billets are reduced to rolled products in high temperature condition. Hot rolling is used mainly to produce sheet metal or simple cross sections from steel billets. In this method metal is passed or deformed between a set of work rolls and the temperature of the metal is generally above its re-crystallization temperature.

It permits easily large deformations of steel to be achieved with a low number of rolling cycles. Because the steel is worked before the formation of crystal structures, it does not itself affect its micro-structural properties. Hot rolling is primarily concerned with manipulating material shape and product’s geometry. It does not affect the mechanical properties of the steel.

Hot rolling is done by heating a component or material to its upper critical temperature and then applying controlled load which forms the material to a desired specification or size.
