and the mold. With the continued passage of the electric current, the slag becomes superheated. The electrode tip is immersed in this superheated slag and begins to melt. The immersion of the electrode in the slag is precisely maintained and a controlled melt rate is established. An advanced computer control system slags that form in electric furnace melting result from complex reactions between silica (adhering sand on casting returns or dirt), iron oxide from steel scrap, other oxidation byproducts from melting, and reactions with refractory linings. The resulting slag will thus consist of a complex liquid phase of oxides
