Effects of slag composition and additive type on desulfurization of rejected electrolytic manganese metal scrap by Na2O-containing electroslag

The recycling rate of rejected electrolytic manganese metal (EMM) scrap can be increased by inhibiting the manganese metal (MM) vaporization during the remelting process with electroslag. However, if the latter is achieved by reducing the remelting temperature, the desulfurization behavior will deteriorate. Therefore, Na2O-containing electroslag and metallic additive were used to increase the rejected EMM scrap recovery ratio. The respective...
