What is the difference between magnesia carbon brick and aluminum magnesia carbon brick

What is the difference between magnesia carbon brick and aluminum magnesia carbon brick? The difference between magnesia carbon brick and aluminum magnesia carbon brick is the use of different raw materials. Magnesia carbon brick is a resin bonded brick made of fused magnesia sand and graphite. If necessary, antioxidants can also be added. Magnesia carbon bricks perform well in terms of heat resistance, corrosion resistance, corrosion resistance, and peel resistance. Magnesia carbon bricks are mainly used as linings for converters, electric arc furnaces, DC electric arc furnaces, and slag lines in steel ladles. Magnesium aluminum carbon bricks are made of high-quality bauxite, corundum, fused magnesia, and graphite. Aluminum magnesium carbon bricks have appropriate residual expansion, low thermal conductivity, and better insulation performance. Aluminum magnesium carbon brick is used for the slag line of the ladle, the lower part of the ladle wall, the bottom of the ladle, and the free zone of the ladle.
