对变压器钢真空脱硫的机理,曾提出了几种解释,包括硫的直接挥发,氧化硫的挥发和 sis 的挥发。和的部份意见相反,Aksoy 用热力学计算证明钢中 s 和 SO_2的蒸汽压很低,认为此二者的挥发很不可能。并曾对冷凝物进行了 x 射线衍射分析和化学分析,从后者发现冷凝物含有 Si 及 s,但从前者 There have been several explanations for the mechanism of vacuum desulfurization of transformer steels, including direct sulfur volatilization, sulfur oxide volatilization, and sis volatilization. Contrary to some of the observations, Aksoy used thermodynamic calculations to demonstrate that the vapor pressures of s and SO2 in steels are low, and it is unlikely that the volatilisation of both will be possible. Condensate was x-ray diffraction analysis and chemical analysis, the latter found that the condensate contains Si and s, but from the former
