AI Technical Summary
In the existing technology, the forging method for martensitic stainless steel journal forgings has problems such as poor billet consistency, many production steps, high difficulty in manual operation, and difficulty in controlling the final temperature, resulting in unqualified grain size of the forgings.
The tooling cavity constraint method is adopted. By designing a special anvil and cavity, the billet size and shrinkage rate are controlled. Forging is carried out using a free forging hammer, which simplifies the billet preparation process and ensures the consistency of the internal structure of the forging.
It improved the grain size qualification rate of forgings, simplified the production process, reduced the operation difficulty, and met the microstructure requirements of forgings.
