Special forging. Special forging including roll forging, wedge rolling, radial forging, forging the way liquid forging steel forgings and other standards, these methods are more suitable for the production of certain special shape parts. For example, a standard flange forgings, roll forging can be used as an effective pre-forming process, dramatically reducing the subsequent molding pressure; wedge rolling ball can be produced, drive shafts and other parts; radial forging can produce a large barrel, stepped shaft, etc. forgings. Forging materials mainly carbon steel and alloy steel of various components, followed by aluminum, magnesium, copper, titanium and its alloys. The original state of the material has bars, ingots, metal powder and liquid metal. In the cross-sectional area of ??the metal before deformation and the ratio of the cross sectional area of ??the deformed called forging ratio. Correct choice of forging ratio, reasonable heating temperature and holding time, reasonable initial forging temperature and the final forging temperature, reasonable amount of deformation and deformation rate to improve product quality, reduce costs a great relationship.
