Hot press forging
Forging temperature range refers to the metal forging temperature and the end of forging temperature interval, in order to prevent overheating, over-burning need to correctly determine the initial forging temperature and final forging temperature.

The purpose of hot forging has three aspects:
1, to reduce the deformation resistance of metal, thereby reducing the deformation of the bad forging deformation of the material required to greatly reduce the tonnage forging equipment;
2, changing the cast ingot structure, after recrystallization in the hot forging process, the coarse as-cast microstructure into a new organization, and to reduce the defects of the as-cast structure and improve the mechanical properties of steel;
3, to improve the plasticity of steel, which is more important for some low-temperature more difficult to forging high-alloy steel
