Ladle Refractories

Alumina magnesia carbon brick With the development of new technologies such as refining and continuous casting, the temperature of molten steel and the residence time of molten steel in ladle can be prolonged, and the refractory material of steel ladle refractory lining is more serious. So the alumina magnesia carbon brick is developed and achieved the expected effect. Al2o3-mgo-c brick is characterized with simple construction, moderate cost, convenient unpacking and good use effect. According to the production need, ladle bricks must have good comprehensive performance.In the high alumina matrix, adding MgO powder, aluminum magnesium spinel can be formed at high temperature, improve the performance of the refractory brick . In order to improve alumina magnesia brick slag resistance, thermal shock resistance, adding the right amount of carbon materials. In order to improve the oxidation resistance of the refractory brick, adding the amount of antioxidant. Alumina magnesia carbo

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
