摘要
介绍了刹车盘类铸件的结构、技术标准和工艺要求，分析了单层浇注工艺存在的问题，包括工艺出品率和生产效率较低，制造成本较高，改进了原有的铸造工艺。生产实践表明，采用双层浇注法生产刹车盘类铸件，砂铁比降低，工艺出品率和生产效率提高，铸件质量符合标准要求，为企业带来了很大的经济效益。
The structure, technical standards and process requirements of brake disc castings were introduced. The problems of single-deck casting process were analyzed, including lower process yield and production efficiency, higher manufacturing cost. The original casting process was improved. The production practice shows that the brake disc castings produced by double-deck casting process can lower sand metal ratio and improve process yield and production efficiency. The casting quality of compliance with requirements has brought great economic benefits for the enterprise.
