Abstract
A process for casting an ingot of pre-alloyed metal from a consumable electrode. It includes the steps of: providing a consumable electrode corresponding to the desired metallurgical composition of the to-be-cast ingot; providing a second electrode; striking an arc between the consumable electrode and the second electrode to melt the consumable electrode and thereby form a molten pool; maintaining the arc between the consumable electrode and the molten pool; rotating or oscillating the consumable electrode about its axis during melting; providing a controlled atmosphere for the melting of the consumable electrode; delivering molten metal into a fluid cooled mold; and withdrawing the ingot from the mold.
