以VD脱氢热力学和动力学为基础,分析了众多因素吹氩流量、真空度、保持真空时间、炉渣碱度和初始氢含量对VD脱氢的影响。对120 t VD的吹氩流量、真空度和保持真空时间等参数进行了优化。结果表明,VD的脱氢效果得到了显著提升,脱氢率基本都稳定在70%以上,平均脱氢率由优化前的56.2%提高到82.6%,最高脱氢率达92.8%。 Based on VD dehydrogenation thermodynamics and kinetics, the effects of argon blowing, vacuum, vacuum time, slag basicity and initial hydrogen content on VD dehydrogenation were analyzed. Parameters such as the argon flow at 120 t VD, the degree of vacuum and the vacuum time were optimized. The results showed that the dehydrogenation effect of VD was significantly improved, the dehydrogenation rate basically stabilized at above 70%, the average dehydrogenation rate increased from 56.2% before optimization to 82.6%, and the maximum dehydrogenation rate reached 92.8%.
