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. So EAF can be used to produce Pure iron, Fine carbon steel, Casting iron, Metal refining, also can be used to hold Temperature for using.
