Magnesia carbon brick series products are designed and manufactured according to different use parts and different use conditions, using high-purity, high-density, or large crystalline magnesia, graphite, resin, etc. as the main raw materials, and forming process by high-tonnage press produce. This product is mainly used for electric furnace lining, and has the advantages of high strength, strong slag resistance, good thermal shock stability, and high refractoriness. According to different smelting conditions, different grades of magnesia carbon bricks can be selected for different parts of the furnace。
