In industrial applications and laboratory studies, it has been shown that the use of water spray may significantly reduce the amount of fume generated from the oxidation process of liquid high carbon ferromanganese alloy. However, in our recent study, it was shown that the oxidation rate of liquid silicon alloy increases with increasing water content in the atmosphere. Therefore, in this paper, the effect of moisture on the oxidation and fume formation of a liquid silicomanganese alloy was investigated. The fuming rate, fume characteristics, and experimental observations from wet air experiments on the silicomanganese melt were compared with those obtained from dry air experiments, and with the results of wet air experiments conducted on high carbon ferromanganese and silicon melts. In addition, the oxidation process of the silicomanganese and high carbon ferromanganese melts was modeled under the experimental conditions, using FactSage 8.1 thermochemical software, to better understand the equilibrium thermodynamic principles of the experimental results. In general, there was good agreement between the simulated and experimentally observed oxidation behavior of silicomanganese and high carbon ferromanganese melts under moist air conditions.

在工业应用和实验室研究中，已经表明使用喷水可以显着减少液态高碳锰铁合金氧化过程中产生的烟雾量。然而，在我们最近的研究中，表明液态硅合金的氧化率随着大气中水分含量的增加而增加。因此，本文研究了水分对液态硅锰合金氧化和烟雾形成的影响。将湿空气实验对硅锰熔体的发烟率、烟雾特性和实验观察结果与干空气实验得到的结果进行比较，并与高碳锰铁和硅熔体湿空气实验的结果进行比较。此外，使用 FactSage 8.1 热化学软件在实验条件下对硅锰和高碳锰铁熔体的氧化过程进行了建模，以更好地理解实验结果的平衡热力学原理。一般来说，模拟和实验观察到的硅锰和高碳锰铁熔体在潮湿空气条件下的氧化行为有很好的一致性。
