我厂从1978年以来铸造高温合金的合格率逐年上升,特别是1980年以来生产的高温合金,无论在产量上还是质量上都创造了历史最好水平。产量与1979年同期相比增长了72.6％,合格率与同期相比提高了12％,尤其是K_1合金合格率为100％,消灭了废品。K_(17)合金的不合格率也从攻关前的35.6％下降到3.82％,满足了生产需要。 The success rate of our foundry superalloy since 1978 has been increasing year by year. Especially the superalloy produced since 1980 has created the best record in history both in terms of output and quality. Compared with the same period in 1979, the output increased by 72.6% and the passing rate increased by 12% over the same period. In particular, the passing rate of K_1 alloy was 100%, which eliminated the waste products. K_ (17) alloy failure rate also dropped from 35.6% before the research to 3.82%, to meet the production needs.
