Refractory Lining of the Electric Arc Furnace

Refractory Lining of the Electric Arc Furnace Refractories are those materials which withstand high temperature without a significant change in chemical or physical properties. Refractory materials are very important to the electric arc furnace (EAF) operation as they allow the containment of the liquid steel in the furnace hearth without damaging the furnace structure. The …
