摘　　要：计算和实测了１８７３Ｋ、气相总压为０．１、０．２、０．３ＭＰａ时的碳—氧平衡曲线，并分析了两者偏差的原因。研究表明，随着气相总压的提高，碳—氧平衡曲线上移，这可很好地解释密封转炉在炉腔高压下吹氧时脱碳的强化。Carbon oxygen equilibrium curves under the condition of 1 873 K and the total pressure of 0.1, 0.2, 0.3 MPa are calculated and measured respectively. The difference between experimental results and calculated values is discussed. It is concluded that, with the increase of the total pressure, the equilibrium curves move upwards. This can be used to elucidate the decarburization reinforcement in a sealed convertor the pressure of which chamber is raised up to a higher level by O 2 blowing.
