Magnesia Carbon (MgO-C) Bricks for EAF
Classification:
Product Introduction
The electric furnace magnesia carbon brick series is designed and manufactured by our company according to the different parts and different conditions of use of the electric furnace. It uses high purity and high density fused magnesia or large crystalline fused magnesia, high purity graphite and so on as the main raw materials, adds special antioxidants, uses phenolic resin as binder, and is formed by high pressure.
The product is mainly used in the lining of electric furnace and is in direct contact with molten steel and slag. It has the advantages of high strength, strong slag resistance, good thermal shock stability and high refractoriness. According to the smelting conditions, different grades of magnesia carbon bricks are selected for different parts of the electric furnace.
