A transient three-dimensional comprehensive numerical model was developed to clarify the effect of electro-emulsification on sulfur mass transfer during the electroslag remelting process of rejected electrolytic manganese metal scrap. The magnetohydrodynamic thermal two-phase flow and solidification behavior were numerically clarified. The kinetics module was established to assess the sulfur mass transfer rate between molten manganese metal and molten slag. Furthermore, variations of the alternating current (AC) magnitude and direction were taken into account. A reasonable agreement between the experimental and simulated results was observed. The surface area of molten droplets was shown to enlarge and it regularly fluctuates under the Lorentz force action. At the constant frequency of 50 Hz, the desulfurization rate rises from 54.7 to 71.0 pct when the AC root mean square (RMS) value of the AC is increased from 3000 to 4000 A, while at the constant AC RMS value of 3500 A, it dropped from 63.4 to 58.5 pct with the frequency increases from 5 to 500 Hz.

电乳化对电渣重熔过程中废电解金属锰脱硫的影响

建立了瞬态三维综合数值模型，以阐明电乳化对废电解锰金属废料电渣重熔过程中硫传质的影响。磁流体动力热两相流动和凝固行为被数值阐明。建立动力学模块以评估熔融锰金属和熔融炉渣之间的硫传质速率。此外，还考虑了交流电 (AC) 幅度和方向的变化。观察到实验和模拟结果之间的合理一致性。熔融液滴的表面积显示出增大并且在洛伦兹力作用下有规律地波动。在50Hz的恒定频率下，脱硫率从54.7上升到71。
