Unfired alumina-magnesia brick is a new type of refractory material, which has the advantages of high refractoriness, high strength and high wear resistance. The application of unburned alumina-magnesia bricks in the ladle lining can effectively improve the purity of molten steel, reduce the impurity content in molten steel, and improve the quality of steel.
The unfired alumina-magnesia brick also has excellent corrosion resistance and can resist the erosion of chemical composition in molten steel, thus prolonging the service life of the ladle. At the same time, the construction of non-burning alumina-magnesia bricks is simple and easy to maintain, which can meet the requirements of rapid replacement of ladle lining.
Aluminum-magnesium-carbon brick is also an important refractory material, which has the advantages of high refractoriness, high strength and corrosion resistance. The application of aluminum-magnesium-carbon bricks in the ladle lining can effectively improve the purity of molten steel, reduce the impurity content in molten steel, and improve the quality of steel.
Aluminum magnesia carbon brick corrosion resistance is also good, can resist the corrosion of the chemical composition of molten steel, so as to extend the service life of the ladle. At the same time, aluminum magnesia carbon brick also has good thermal insulation performance, can reduce the temperature fluctuation of molten steel, improve the stability of steel.
When unfired alumina-magnesia bricks and alumina-magnesia-carbon bricks are used in ladle lining, appropriate materials need to be selected according to different use conditions. For example, in a high-temperature environment, it is necessary to select a material with high refractoriness; in a condition that needs to withstand a large pressure, it is necessary to select a material with high strength, etc.
In short, unfired alumina-magnesia bricks and alumina-magnesia-carbon bricks have important application value in the ladle lining, which can improve the quality of steel and the service life of the ladle. With the continuous development of science and technology, the performance and types of these refractories will continue to be improved and perfected.
