摘　　要：针对某典型锻件前期试制中无损检测不合格问题,采用真空碳脱氧(VCD)和铝脱氧方式相结合,使钢锭气体含量、夹杂物评级结果及宏观偏析都得到了明显改善。大大提高了钢锭冶金质量,锻件无损检测合格率达100%。Aiming to the unqualified problem of some typical forging in nondestructive test during trial - manufac- ture, vacuum carbon deoxidation method （VCD） and aluminum deoxidation method are combined to make gas content, inclusion grade and macroscopic segregation of ingot achieve obvious improvement. The metallurgy quality of ingot has been improved and the qualified rate of nondestructive test for forging is 100%.
