| 摘 要： | 实验在MoSi2电阻炉内用饱和浓度法测试了Fe C N体系氮的浓度和活度，并根据含化合物的金属熔体结构的共存理论模型，推导了Fe C N金属熔体作用浓度计算模型。实验测得1 485 ℃碳饱和的Fe C N熔体中在氮分压01 MPa时氮的溶解度为0006 5%，并且计算的作用浓度与相应的实测活度相符合，从而证明所得模型可以反映Fe C N金属熔体的结构本质，由模型得出金属熔体高碳含量有利于脱氮。 |

| Abstract: | In MoSi2 high temperature furnace the concentration and activity of N in Fe C N system were measured, and according to the coexistent theory about metal melt structure containing compounds, the computational model of action concentration of Fe C N system is got. The experimental result shows that at 1 485 ℃ the nitrogen solubility in this carbon saturation melt is 0006 5% for nitrogen partial pressure of 01 MPa. The computed action concentration accords with the relevant measured activity, which proves that the model can express the structural quality of Fe C N metal melt. This model shows that high carbon content in metal melt is beneficial to the denitrification. |
