An electroslag remelting process for manganese-base alloys. The process includes the steps of: partially immersing a consumable electrode of a manganese-base alloy in a layer of molten slag and passing current between the consumable electrode and a second electrode. The current is passed through the slag layer under conditions which gradually melt the consumable electrode so that drops of molten metal from the consumable electrode move downwardly through the slag layer and resolidify as an ingot thereunder. The slag is characterized by a fusion temperature of more than 300.degree. F. (149.degree. C.), and often more than 350.degree. F. (177.degree. C.), above the melting point of the consumable electrode. It is preferably comprised of Al.sub.2 O.sub.3, CaO and CaF.sub.2.
