摘要
根据热力学原理分析了铬矿直接合金化的合理性及其影响因素,并对熔渣碱度、铬矿加入量和还原剂的影响进行了实验研究。其结果表明,熔渣碱度控制在1.5左右,加人铬矿后熔渣中Cr_2O_3含量低于30％,先用碳还原再用硅还原,可以获得较好的冶金效果。
The reasonableness of direct alloying with chrome ores is discussed with thermodynamical analysis as well as the influencing factors, such as the burden of chrome ores, basicity of slag and reductants. The results of experiments have shown that the basicity of slag should be around 1.5 and the chrome ore burden was limited up to 30% of Cr2O3 in slag. Carbon was used as reductant first and then silicon to continue for better metallurgical effect.
