Ladle Refractories

magnesia carbon bricks Magnesia carbon bricks is a high melting point of basic oxide oxide (melting point 2800 ℃) and difficult to be slag invasion of high melting point carbon material as raw material, add a variety of non-oxide additives. With carbonaceous binder combination of non-burning carbon composite refractory material . The traditional magnesia carbon brick produced by the synthetic tar binder in the cold mixing process is hardened during the damage of the tar and the necessary strength is obtained, thus forming isotropic glassy carbon. The carbon does not exhibit thermoplasticity, and the thermoplastic properties are eliminated in a large amount of stress during lining or during operation. The bituminous carbon bricks produced by the asphalt binder has a high high temperature plasticity due to the formation of anisotropic graphitized coke during the asphalt carbonization process. Therefore, the use of asphalt combined with the brick crack resistance is higher than the...

magnesia carbon brick Magnesia carbon brick is a kind of important refractory material used in steelmaking converter, steel making electric furnace, steel refining furnace and its ladle as lining (lining). As the erosion resistance, not easy to slag, so the use of magnesia brick can significantly improve the life of steel-making furnace (bag). Magnesia carbon bricks is the use of high-quality fused magnesia, high purity flake graphite, metal additives and other raw materials, phenolic resin as a binder by high-pressure molding, about 200 ℃ heat treatment made of a refractory material . High quality magnesia carbon bricks to ensure the service life and safety, the use of poor quality magnesia carbon brick masonry furnace easy to burn, the occurrence of running steel, leakage of steel, casualties and other vicious accidents, so the procurement must be good Quality off. Magnesia carbon refractory brick the classification of magnesia carbon bricks and provides the correspondin...
