1600马力柴油机的汽缸套,结构是比较复杂的,不但铸件本身很薄,尤其在隔层的 地方厚度更薄,所以在铸造上有一定的困难。由於在生产前经过几次详细周密的研究, 才确定了铸造方法,并编制了工艺卡片,因此试造情况很好。投入生产后,合格率达到 97%。 1600 horsepower diesel engine cylinder liner, the structure is more complicated, not only the casting itself is very thin, especially in the thickness of the compartment where the thinner, so the casting has some difficulties. Due to several detailed and careful studies before production, the casting method was determined and a process card was prepared, so the test was very good. Put into production, the pass rate of 97%.
