The advantage of hot rolling is that it can eliminate certain defects in the cast metal, such as welding pores, refining coarse grains and changing the distribution of inclusions, so that the compactness and mechanical properties of the metal are improved.

The main factors affecting rolling pressure are absolute rolling reduction, mill roll diameter, rolling piece width, thickness of rolled piece, rolling temperature, Coefficient of friction, the chemical composition of the rolled product and rolling speed.

An operation in which steel is heated above a critical point or recrystallization temperature for a period of time and then slowly cooled to a cooling rate less than that in still air is called annealing. After the steel is austenitized and rapidly cooled at a rate greater than the critical cooling rate, the supercooled austenite can be transformed into martensite. This operation is called quenching.
