摘　　要：针对25Cr2Ni4MoV大型风机轴用钢探伤要求较严格且不采用电渣重熔工艺生产的特点,分析了该钢种冶炼控制难点,制订了相对应的关键工艺控制点,确定采用双真空工艺生产25Cr2Ni4MoV风机轴用钢,经检测化学成分、力学性能、超声波探伤完全满足标准要求,完全可以替代电渣钢。For the strictly requirements on UT and no adopting the ESR production process, the smelting control difficulties of this steel grad had been analysis, and accordingly the key control points had been made. And the use of double vacuum process to produce 25Cr2Ni4MoV fan shaft steel had been also determined finally. The final steel product quality after testing had fully met the standard requirements on the chemical composition, mechanical properties, ultrasonic testing, and can completely replace the ESR steel.
