实验在MoSi2电阻炉内用饱和浓度法测试了FeCN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FeCN金属熔体作用浓度计算模型。实验测得1 485 ℃碳饱和的FeCN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FeCN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。
In MoSi2 high temperature furnace the concentration and activity of N in FeCN system were measured, and according to the coexistent theory about metal melt structure containing compounds, the computational model of action concentration of FeCN 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 FeCN metal melt. This model shows that high carbon content in metal melt is beneficial to the denitrification.
