Desulfurization of molten steel with molten slag using the electrochemical method

The desulfurization in metallurgical process is electrochemical reaction nature. Desulfurization using the method was proposed with CaO-MgO-Al2O3 molten slag covering steel. Effect of an applied external DC voltage, which varied from 0 to 8V, discussed. results indicated that sulfur steel could be removed effectively voltage. According mechanism analyses under kinetics formulae were developed, and model calculated agreement experimental values. transfer coefficient electromigration conditions approximately 2.09?10-5 m?s-1?V-1. can promoted by increasing reducing partial pressure atmospheric oxygen, strengthening stirring intensity system, optimizing composition properties slag.
