Different Forged Valves
Forging supercritical valves Supercritical valves are mainly used in thermal power projects, there is no difference for forging processes for small forgings and conventional forging processes. Large forgings weigh several tons, and forging processes are as follows: ⑴ It is necessary to ensure the correctness of the heating process and a sufficient and suitable forging ratio, because if the forged valve is re-heated, the grains will recrystallize and grow through the external...
