Common knowledge of magnesia carbon brick manufacturers

The PN series of magnesium aluminum carbon bricks use high-grade bauxite or corundum as aggregates, with a focus on strengthening the matrix, phenolic resin as a binder, and machine pressed forming. They have the characteristics of corrosion resistance, peeling resistance, and high strength, and are suitable for steel ladle bottom and wall parts.


The PN series magnesium aluminum carbon bricks have adjusted the process and technology based on aluminum magnesium carbon bricks, enhancing the material's corrosion resistance and peeling resistance. They are suitable for the bottom and wall of steel ladles, and can significantly improve the service life of steel ladles. The application of carbon in refractory materials has been quite extensive in the current metallurgical industry. In the past, many new products have been developed to adapt to new metallurgical processes and the development of refractory material technology. Refractory experts have long understood the excellent performance of magnesium aluminum carbon bricks exhibited by different forms of carbon in refractory materials. In refractory oxides, carbon can reduce the wettability of slag, molten steel, and refractory materials, increase their thermal conductivity, and reduce their expansion, thus making refractory materials have excellent thermal shock resistance. In addition, carbon has high thermal stability, with a sublimation temperature of about 4000 ℃. At a pressure of 110-140 bar, the three-phase point (solid/liquid/gas) of carbon in the phase diagram approaches 4020 ℃. Therefore, when the pressure is below 110 bar, carbon sublimates but does not melt. Due to the oxidation of carbon at high temperatures, the above research results can only be applied under specific conditions.
