What should we pay attention to when forging?

Jun 14,2024

When considering the forging temperature, the temperature drop during the contact process between the blank and the mold should be taken into account, and the mold should be preheated.

For alloys with high degree of difficulty in deformation, slow deformation should be used as much as possible, and the deformation amount of each stroke of each hammer or press should be controlled, generally around 20%. For speed sensitive materials, the selection of deformation speed should also consider the effect of Hebei Wenzhou Railway forgings on the quality of the entire railway.

The plasticity of closed die forging is better than that of open die forging, and open die forging is better than free forging. In the free forging process, the elongation of the die anvil and the upsetting with the ring are more able to exert the plasticity of the metal than the elongation of the flat anvil and the upsetting without the ring.
