Abstract：A 9Cr2Mo roller shaft forging has been successfully developed using a 65 t mold ingot and reasonable planning of smelting,forging,and heat treatment processes.The casting process parameters for smelting were optimized.Forging increases high-temperature diffusion,reduces segregation,and ensure compacts and penetrates in the forging process.Heat treatment and tempering spheroidization ensure sufficient tempering time.The forgings pass the flaw detection,and the microstructure and hardness can meet the technical requirements.
