What should be noted during forging?

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

For alloys with high deformation difficulty, slow deformation should be adopted as much as possible, and the deformation amount of each hammer or press stroke should be controlled, generally around 20%. For speed sensitive materials, the selection of deformation speed should also consider the impact of Hebei Wenzhou Railway forgings on the overall quality of the 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 process of free forging, the elongation of the die anvil and the upsetting with a ring can better exert the plasticity of the metal than the elongation of the flat anvil and the upsetting without a ring.
