1, hot forging in the metal recrystallization temperature above the forging process.
2, hot rolling in higher than the recrystallization temperature of the rolling process.
3, cold rolling: plastic deformation temperature below the recovery temperature of the rolling process.
4, annealing: the metal is slowly heated to a certain temperature, maintained for a sufficient period of time, and then cooled at an appropriate rate (usually slow cooling, sometimes controlled cooling) of a metal heat treatment process.
5, pickling: immersed in an aqueous solution of sulfuric acid, etc., to remove oxides and other thin films on the surface of the metal. Is plating, enameling, rolling and other processes of pretreatment or intermediate treatment.
