【摘要】 试验研究了德国牌号GGG40球铁的生产方法。确定了铸件成分、熔炼工艺,对材料的力学性能和金相组织进行了测试和简要分析。通过了装车测试,各项性能指标均达到并超过进口铸件的标准,完全实现了国产化。更多还原

【Abstract】 The production process of GGG40 grade Germany Standard ductile iron was researched. The composition of casting melting process was determined through experiments mechanical properties and structure of the material was tested examined and analyzed. The bus running test showed that all properties have reached or surpassed the level of imported castings so the production of this type castings in China has been realized.更多还原
