Ladle Magnesia Carbon Brick Introduction：
Magnesia carbon brick is made of fused magnesia and high carbon graphite, with antioxidant was added, and the phenolic resin was used as the binder for high pressure molding. MgO-C refractory bricks are widely used in steel industry. General magnesia-carbon bricks are made of high-quality magnesia with high-purity graphite, silicon, silicon carbide and other additives, and phenolic resin as a binding agent.
Magnesia carbon bricks are widely used in steel industry, the primary consumer of refractory linings, such as basic oxygen furnaces, electric arc furnaces, and ladle furnaces.
Ladle Magnesia Carbon Brick Advantages：
Anti-erosion, anti-stripping, high strength. When MgO-C bricks are used for refining ladle furnaces and ladles, they are mainly used in headroom and slag lines. According to the operating conditions, the refractory materials used in these parts must have high temperature resistance, thermal shock resistance, and resistance to mechanical corrosion caused by slag erosion.
Ladle Magnesia Carbon Brick Features：
1. The melting point of high temperature -resistant graphite is 3850 ° C ± 50 ° C, and the boiling point is 4250 ° C. Even after burning with high arcs, the quality loss is small, and the line expansion coefficient is small. Graphite strength is strengthened with the temperature. At 2000 ° C, the graphite strength is doubled to double the turning furnace with magnesium carbon bricks
2. Conductive and thermal conductivity. The conductivity of graphite is twice as high as ordinary non -metal ore. Thermal conductivity exceeds more than steel, iron, lead and other metal materials. The thermal guidance rate decreases with the increase in temperature, and even at extremely high temperatures, graphite is a thermal body.
3. Lubrication. The lubrication of graphite depends on the size of the graphite scales. The larger the scales, the smaller the friction coefficient, and the better the lubrication performance
4. Chemical stability, graphite has good chemical stability at room temperature, can resist acid, alkali resistance, and organic solvent corrosion
5. Plasticiac. Graphite is very tough and can be crushed into thin thin slices.
6. Anti -heat shock. Graphite can withstand the severe changes in the temperature at high temperature without damage. When the temperature mutations, the volume of the graphite does not change much and does not cause cracks. The combination agent plays the role of connecting the matrix and particles. In the process of actual production and use, the matrix and binding agent system is two weak links.
