EAF(Electric Arc Furnace) is mainly used for steelmaking with steel scrap as the main raw material. Accordingly to power types, EAF are mainly divided into DC EAF and AC.
Same as other high temperature induction furnaces, refractory materials are widely used for EAF. EAF refractory materials are mainly as following,
Magnesia, magnesia carbon, magnesia aluminum and magnesia chrome refractories are widely used in DC EAF. Alkaline bricks without carbon is widely used in Europe, while in Japan, thermal shock resistance is thought as a great question, so they prefer to use magnesia carbon brick with high carbon content. In order to improve thermal shock resistance and corrosion resistance of metallurgical equipment, magnesia spinel materials and magnesia-chrome brick are widely used in Europe.
For small AC EAF, asphalt brick, magnesia carbon brick, magnesia gun mix are widely used at furnace wall. For ultra-high power electric AC EAF, high-quality magnesia carbon brick would be used for furnace wall, while for slag line, higher performance high-magnesia carbon brick would be needed. Out of magnesia carbon bricks, magnesia gun mix would be used to repair furnace wall during working.
