Thermal Shock Resistance Magnesia Carbon Bricks Refractory Brick Custom Made
Factory Price Magnesia Carbon Bricks Refractory Brick Top Quality Custom Made
Magnesium-chromium refractory brick is a magnesia-based refractory material containing chromium trioxide. By solid-melting chromium oxide in periclase and forming low-expansion magnesia-chromium spinel, it can increase the wetting angle of the liquid relative to the refractory phase and improve the The degree of direct bonding produces an ideal periclase-magnesium-chromium spinel-microcrack composite structure, so that the magnesia-chromium refractory brick has good load temperature, high temperature strength, corrosion resistance, thermal shock stability, and low thermal conductivity. rate and better hanging kiln skin. Magnesia-chromium refractory bricks have a high performance/price ratio among the existing fired zone refractories, and thus become a widely used refractory material.
