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.
