The difference between magnesia carbon bricks and aluminum magnesia carbon bricks, the raw materials used are different

What is the difference between magnesia carbon bricks and aluminum magnesia carbon bricks? The difference between magnesia carbon bricks and aluminum magnesia carbon bricks is that the raw materials used are different. Magnesia carbon bricks are resin-bonded bricks made of fused magnesia. Made of sand and graphite. Magnesia-carbon brick manufacturers, if necessary, can also add antioxidants, magnesia-carbon bricks perform well in heat resistance, corrosion resistance, corrosion resistance and peeling resistance. Magnesia-carbon bricks are mainly used in converters, electric arc furnaces, linings of DC electric arc furnaces, ladle slag lines and other parts. Magnesia brick manufacturers

Magnesia alumina carbon bricks are made of high quality bauxite, corundum, fused magnesia and graphite. Alumina magnesia carbon bricks have proper residual expansion, low thermal conductivity and better edge properties. Aluminum-magnesium-carbon bricks are 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. The magnesia contained in magnesia-carbon bricks is determined according to what material is used. Common magnesia-carbon bricks are mainly 72% magnesia, 74% magnesia, 76% magnesia, 80% magnesia, 82% magnesia, 85% magnesia % magnesia, magnesia-carbon brick manufacturers, the main raw materials used in the production of magnesia-carbon bricks are fused magnesia, graphite, metal aluminum powder, metal silicon powder, liquid phenolic resin mixed by a sand mixer and pressed by a press. Carbon bricks are used in refining ladle slag lines, and magnesia carbon bricks are also used in furnace linings such as AC electric arc furnaces, DC electric arc furnaces, and converters.

Magnesia-carbon bricks are made of magnesia, dead-burned magnesia, fused magnesia, high-purity magnesia and high-quality graphite and bauxite additives. The price of magnesia-carbon bricks and its performance have a lot to do with the graphite content in the bricks. As the graphite content increases, the strength of the brick decreases, the thermal expansion rate decreases, and the residual expansion rate increases.

Therefore, the graphite content in the brick should be controlled at about 20%. Magnesia-carbon bricks have low wettability to slag, and have excellent resistance to spalling and erosion. They are suitable for the slag line of the ladle, especially in the case of multi-furnace continuous casting. In order to meet the needs of producing clean steel, the application part of magnesia-carbon bricks has been expanded from the slag line to the side wall during refining in the ladle. Ladle magnesia carbon brick

When laying magnesia-carbon bricks on the ladle, care should be taken not to mix with bricks containing high SiO2. Otherwise, the local melting loss of magnesia-carbon bricks will be increased, and the melting loss mechanism is:

It is mainly used for the lining and tapping port of the steel-making oxidation reformer, the hot spot of the furnace wall of the high-power electric furnace, the lining of the refining furnace outside the furnace, the slag line of the steel ladle, etc.
