采用热模拟技术，对于铸件不同模数，就Ｃｒ２７抗磨白口铸铁中的锰、钼、镍（铜）等 合金元素对铸铁硬度的影响进行了研究．对于中等壁厚铸件，找到了合适的Ｃｒ２７抗磨白口的 化学成分和热处理规范．用研制的合金成分生产杂质泵铸件，其使用寿命长．
The effects of alloying elements, such as manganese, molybdenum and nickel (copper), on the hardness of cast iron in Cr27 anti-wear white cast iron were studied by using thermal simulation technique. For medium-wall castings, the chemical composition and heat-treatment specifications for a suitable Cr27 anti-wear white finish were found. Impurity pump castings are made from the alloying components developed for long service life.
