Ladle Refractories

Magnesia Chrome Brick Magnesia Chrome Brick, Chrome Brick   Magnesia Chrome Brick Magnesia chrome brick is made of some preliminary synthesis high purity raw materials. The high purity raw refractories should be high pressure formed, ultra high temperature fired and then go through some other post-treatment process and system, finally made the magnesite chrome brick. The magnesia chrome brick has high room temperature compressive strength, low porosity, strong erosion resistance and scouring resistance, etc. Usually it is used for bottom part of VOD. http://www.ruizhirefractory.com/en/product/magnesia-chrome-brick.html Email: sales@ruizhirefractory.com

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...

magnesia carbon brick Magnesia Carbon Brick Ladle magnesia carbon brick takes use of fused magnesia sand, high carbon graphite as raw material, adding proper amount of antioxidants, bonded with phenolic resin,made by high pressure molding. Good erosion resistance and shock resistance. Generally used in furnace lining.

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...

The magnesia chrome brick has high room temperature compressive strength, low porosity, strong erosion resistance and scouring resistance, etc. Usually it is used for bottom part of VOD. Magnesia chrome brick types Production of magnesia chrome brick with raw materials are: natural raw materials, synthetic raw materials and industrial chromium oxide and industrial alumina and other natural raw materials. Such as various grades of sintered magnesia, ordinary chrome ore and low impurity content of chromium concentrate synthetic raw materials: from the magnesite and chrome concentrate by grinding, mixing, compacting, and then calcined at high temperature made a total of Sintered magnesia chrome material; and by the magnesite and chrome ore by the fused fused refractory brick company magnesia chrome material; there are fused magnesia synthetic materials should generally be low impurities in raw materials. The above raw materials are used differently. Combination and formula can be mad...
