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

What is the difference between magnesia-carbon brick and aluminum-magnesium-carbon brick? The difference between magnesia-carbon brick and aluminum-magnesium-carbon brick is that the raw materials used are different. Magnesia-carbon brick is a kind of resin-bonded brick made of fused magnesia. Made of sand and graphite. The price of magnesia carbon bricks, if necessary, you can also add antioxidants, magnesia carbon bricks are good in heat resistance, corrosion resistance, corrosion resistance and peeling resistance. Magnesia-carbon bricks are mainly used for linings of converters, electric arc furnaces, DC electric arc furnaces, and ladle slag lines. Magnesia-aluminum carbon bricks are made of high-quality bauxite, corundum, fused magnesia and graphite. Aluminum-magnesium-carbon bricks have proper residual expansion, low thermal conductivity and better insulation properties. The aluminum-magnesium-carbon bricks are used in 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. Light burnt magnesia powder
