AI Technical Summary

Problems solved by technology

[0003] The traditional method of testing the cold and heat fatigue performance of metal materials needs to consume most of the manual operation time. The traditional heating furnace is not closed, so the required temperature or holding time cannot be reached during the heating and heat preservation process.

Moreover, the traditional cooling barrel can only hold one kind of cooling reagent, and the environment is relatively single, which cannot simulate various experimental environments well. In addition, the cooling liquid will cause deviations in the experimental results due to the increase in water temperature during quenching.
