通过添加氮化合金氮化铬和氮化锰冶炼高氮钢,对氮化铬和氮化锰中的夹杂进行对比实验。从增氮效果上来看,氮化锰增氮效果明显不如氮化铬,说明氮化锰的夹杂含量要多于氮化铬,通过对所冶炼钢锭相同部位取金相试样做夹杂物分析,采用氮化锰增氮钢锭最终的夹杂物含量也要多于采用氮化铬增氮的夹杂物含量。实验结果表明,氮化铬比氮化锰更纯净。 By adding nitrogen nitride alloy chromium nitride and manganese nitride smelting high nitrogen steel, chromium nitride and manganese nitride inclusions for comparative experiments. From the point of increasing nitrogen effect, the effect of increasing nitrogen by manganese nitride is obviously not as good as that of chromium nitride, indicating that the content of manganese nitride is more than the content of chromium nitride. By taking the metallographic sample from the same part of the smelting ingot as inclusion analysis, The content of inclusions in the ingot with manganese nitride increased more than that of inclusions added with chromium nitride. The experimental results show that chromium nitride is purer than manganese nitride.
