Electric arc furnace carbon steel slag (EAF)

An Electric arc furnace (EAF) produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current Lime added (as flux) combine with silicates and oxides to form liquid slag. EAF slag has a lower density than steel and therefore floats on top of the molten steel.
