在机械工业材料应用技术中,合理选材是十分重要的研究课题。特别是合理选材与结构设计及制造工艺相结合,更是提高机械工业科技水平的一项综合技术。热处理炉用耐热钢是机械工业中使用量大面广的关键材料之一,但由于缺少数据和选材依据,更没有形成完整的用钢体系,因此,材料选用缺少科学依据。此外,炉用构件绝大部分又为砂型铸件,精铸件很少,材料利用率低,
In the application of mechanical industrial materials technology, the rational selection is a very important research topic. In particular, a reasonable selection of materials and structural design and manufacturing processes combined, but also to enhance the level of science and technology machinery industry an integrated technology. Heat-treated furnace heat-resistant steel is one of the most important materials used in the machinery industry. However, due to the lack of data and materials selection, a complete steel system is not formed. Therefore, the selection of materials lacks scientific basis. In addition, the vast majority of furnace components and sand casting, casting few, low material utilization,
