提供了一种新的钢液无污染脱氧的方法。对比研究了在钢液与CaO(35%)-Al2O3(55%)-MgO(10%)(质量分数)熔渣间不加电压(断路),外加电压U=0.5 V和U=1.0 V 3种条件下的脱氧情况,试验结果表明脱氧速率随着外加电压的增加而增加。此外,推导并分析了电化学脱氧的机制方程,发现可以通过增强钢液搅拌强度,加大外加电压,选择高电导率、高碱度、低黏度的渣系,降低外电路电阻等措施来加快电化学脱氧的速度。
A new method of pollution-free deoxidation of molten steel is provided. The comparison between the molten steel and CaO (35%) - Al2O3 (55%) - MgO (10%) (mass fraction) slag without voltage (open circuit) and the applied voltages U = 0.5 V and U = 1.0 V 3 Under the conditions of deoxidation, the test results show that the deoxy rate increases with the increase of applied voltage. In addition, the mechanism equation of electrochemical deoxidation is deduced and analyzed. It is found that the mechanism of electrochemical deoxidation can be accelerated by increasing the stirring intensity of molten steel, increasing the applied voltage, choosing the slag system with high conductivity, high alkalinity and low viscosity, and reducing the external circuit resistance Electrochemical deoxidation speed.
