熔模铸造碳钢件过滤技术研究

The Research of the Filtration Technique on Investment Carbon Steel Castings

介绍了采用耐高温纤维过滤网净化熔模碳钢件的新方法及其生产试用效果。研究表明,所用过滤方法能改善碳钢件的组织和性能,有效去除非金属夹杂物,对提高熔模铸造碳钢件质量有实用意议。

A new process of the refinement invetment carbon steel castings and its applycation effects are introduced in this paper. The research shows that the filtration technique can improve structure and properties of the carbon steels, reduce such casting defects as inclusion and gas hole in carbon steel castings, and improve the quality of
