DC Electric ARC furnace for Casting iron/Metal refining/Fine cabon steel melting. When ferro ore was reduced to sponge iron by blast furnace, it must be melted by Electric Arc Furnace (EAF) to remove the impurities, then adjust the component to your required steel.

Electric arc furnace Wikipedia

An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary steelmaking.

DC Arc Furnaces — Past, Present, and Future | SpringerLink

Abstract. DC arc furnaces were first used industrially for the reductive smelting of chromite fines to produce ferrochromium thirty years ago. Since then, they have been used for a variety of applications, including the smelting of ilmenite to produce titania slag and pig iron, the recovery of cobalt from non-ferrous smelter slags, and the smelting of nickel laterite ores to produce ferronickel.
