测定了1300,1400,1500℃温度下,在铁液中Sb对碳的溶解度的影响,碳的溶解度随Sb量的增加而减小,推算出碳饱和铁液中Sb与C的相互作用系数与温度的关系。＊e_C~(Sb)=11.309/T+0.0025 ＊e_(Sb)~C=128.023/T-0.0219 Fe基稀溶液中Sb与C的相互作用系数与温度的关系: e_C~(Sb)=14.204/T+0.025;e_(Sb)~C=120.541/T+0.227 ε_C~(Sb)=ε_(Sb)~C=6026.75/T+11.958 估算出1600℃时＊e_C~(Sb)=0.0085,e_C~(Sb)=0.033,e_(Sb)~C=0.295,ε_C~(Sb)=ε_(Sb)~C=15.36。结果表明,相互作用系数随温度的变化不明显。
The effect of Sb on the solubility of carbon in molten iron was investigated at 1300, 1400 and 1500 ℃. The solubility of carbon decreased with the increase of Sb. The interaction coefficients between Sb and C in carbon saturated molten iron The relationship between temperature. The relationship between the interaction coefficient of Sb and C in Fe-based dilute solution is: e_C ~ (Sb) = 14.204 / T = 0.0025 * e Sb (Sb) (Sb) = 0.0085, e_C ~ (Sb) = 0.0085 at 1600 ℃ is calculated by the following formula: T + 0.025; (Sb) = 0.033, e_ (Sb) ~ C = 0.295, ε_C ~ (Sb) = ε_ (Sb) ~ C = 15.36. The results show that the interaction coefficient with the temperature changes is not obvious.
