What is Importance of Foamy Slag in EAF about?

Slags play an important role in electric arc furnace (EAF) steelmaking. They form from oxides in the scrap, refractories, and added lime and magnesia. An optimal slag covers the electric arcs to improve efficiency, removes impurities from the steel, and protects refractories and metal. It achieves good foaming from carbon monoxide bubbles generated at the metal-slag interface and optimized viscosity/surface tension through saturation with calcium oxide or magnesium oxide. Controlling slag composition and pr
