合成铸铁熔炼过程中增碳剂与碳化硅的最佳配伍

Optimum Compatibility of Carburizer and Silicon Carbide in the Melting Process of Synthetic Cast Iron

合成铸铁熔炼,增碳剂与碳化硅除了调整碳量,并在铁液中生成大量弥散分布的非均质结晶核心,特别是碳化硅的成核效果和伴生功能,强化铁液的孕育预处理,对改善基本组织和石墨形态提高铸件综合性能,具有重要意义。

Synthetic cast iron smelting,carbonizing agent and silicon carbide not only adjust the amount of carbon,but also a large number of dispersed and distributed heterogeneous crystalline cores are formed in the molten iron.In particular,the nucleation effect and associated function of silicon carbide,strengthening the inoculation pretreatment of molten iron.It is of great significance to improve the basic structure and graphite morphology of casting.
