mechanical forging process

Forging is a common forming method in mechanical manufacturing. The as-cast looseness and welding holes of the metal can be eliminated by forging, and the mechanical properties of forgings are generally better than castings of the same material. For important parts with high load and severe working conditions in machinery, forgings are mostly used except for plates, profiles or weldments that can be rolled with simple shapes.X6432 X6436 UNIVERSAL ROTARY HEAD MILLING MACHINE Forging can be divided into cold forging and hot forging according to the temperature of the blank during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the blank metal. Sometimes it is also called warm forging when it is heated but the temperature does not exceed the recrystallization temperature. However, this division is not completely uniform in production.XQ6432 SERIES UNIVERSAL SWIVEL HEAD MILLING MACHINE The recrystallization temperature of steel is about 460°C, but 800°C is generally used as the dividing line, and hot forging is above 800°C; it is called warm forging or semi-hot forging between 300 and 800°C.Analysis of carbon content on the surface of carburized parts Forging materials are mainly carbon steel and alloy steel with various components, followed by aluminum, magnesium, copper, titanium and their alloys. The original state of the material is bar stock, ingot, metal powder and liquid metal.Precision carburizing heat treatment of gears
