摘要
针对船用柴油机机体球化率要求高的特点,从原材料的选用、球化处理、孕育处理、球墨铸铁的球化衰退控制等几方面就如何提高船用柴油机机体球化率进行了分析。指出:球墨铸铁的生产过程比较复杂,必须在各个环节按规范操作运行,才能保证铸件的质量。
Aimed at high nodularity of marine diesel engine block, analysis was carried out on how to im- prove the nodularity from the aspects of material, spheroidization, inoculation, as well as nodularity fading of nodular cast iron. cedure should follow Keywords： marine It is pointed out that nodular cast iron has complex production process and every pro- the operation rules to ensure the quality of casting.
