建立了RH碳氧反应模型,计算值和实际测量值吻合较好,可以模拟实际RH精炼过程中的碳氧反应.在一定的初始碳含量范围内,初始碳含量对RH脱碳结束的碳含量基本没有影响,同时,RH脱碳反应达到14min后其脱碳速度小于1.5×10-6min-1,脱碳反应接近平衡.随着钢包渣TFe含量的增高,RH脱碳反应降低的氧含量和碳含量的比值在降低.当钢包渣TFe含量为8%时,实际计算的碳氧线和理论的碳氧线接近.
The RH carbon-oxygen reaction model was established, and the calculated value is in good agreement with the actual measured value, which can simulate the carbon-oxygen reaction in the actual RH refining process.In a certain range of initial carbon content, the carbon content While the decarburization rate is less than 1.5 × 10-6min-1 after RH decarburization reaction reaches 14min, and the decarburization reaction is close to equilibrium.With the increase of TFe content of ladle slag, the oxygen content decreased by RH decarburization reaction and The ratio of carbon content is decreasing.When the TFe content of ladle slag is 8%, the actual calculated carbon-oxygen line is close to the theoretical carbon-oxygen line.
