The finishing of complex forgings may be accomplished

The finishing of complex forgings may be accomplished with only a process or several processes. After the hot working forging process, the casting organization deforms, and the original coarse dendrite and columnar grains turn into the equiaxed recrystallization with thinner grains and uniform size because of the deformation and recrystallization of the metal. It is also one of the two major components of forging (forging and stamping). 

The forging process builds a refined particle structure and improves the physical properties of the metal. The basic working procedure of free forging includes upsetting, pulling, punching, cutting, bending, torsion, dislocation shifting and forging. Special forging. Hot forging is adopted in free forging. However, it should be noted that the blank can not be completely restricted. These methods are suitable for the production of some certain special shape parts. Free forging refers to the processing methods that use simple, general tools, or directly exert forces to the blank between the upper and lower anvil iron in the forging equipment in order to obtain the required geometrical shape and internal quality of forgings from the deformation of the billet. 

As the name suggests, the material is individually ferrous metals like carbon and steel, non-ferrous metal like copper and aluminum, and powder metallurgy materials.Forging categoriesAs mentioned above, forging can be divided into hot forging, warm forging and cold forging according to the forging temperature. In the actual use of parts, a correct design can make the particle flow in the direction of the main pressure. Ring rolling refers to the ring-shaped parts with different diameters that is produced through a dedicated equipment mill, and it is also used to the production of wheel parts such as automobile wheels and train wheels. Warm forging and cold forging are the future development direction of die forging, which also represent the level of forging technology.
