Description

Brief introduction of corundum mullite brick

Corundum and mullite bricks refer to high-alumina refractory products composed of main crystal phases of corundum and mullite. Corundum-mullite bricks refer to refractory products made of high-purity or relatively pure raw materials. The presence of low melting point oxide impurities will reduce its high temperature performance. Use industrial alumina powder and pure clay, bauxite or silica as raw materials to synthesize pure mullite raw materials, especially the content of alkali metal oxides should be as low as possible.


Composition of corundum mullite brick

Corundum and mullite bricks are made of corundum and mullite as the main raw materials, and are fired at high temperature in an oxidizing atmosphere by adding appropriate amounts of alumina, silica ultrafine powder and additives. The content of AL2O3 is 72%~90%.


Advantages and characteristics of corundum mullite brick

(1) High temperature resistance, high refractory temperature and high load softening temperature.

(2) Chemical resistance, strong resistance to acidic solutions or molten slag.

(3) Antioxidant. It is not easy to react with O2, H2, CO and other gases.

(4) Good thermal stability, stable volume at high temperature, not easy to expand or shrink.

(5) Good thermal shock resistance, resistance to rapid cold and heat and not easy to peel off.

(6) High compressive strength at room temperature, and it is not easy to wear when handling or unloading.


Application of corundum mullite brick

white corundum mullite brick can be directly exposed to flame, peel off, and high temperature resistance. They can be used as heat insulation linings for high-temperature industrial furnaces and working layers for other industrial high-temperature furnaces. They are mainly used in petrochemical industry and large and medium-sized synthetic ammonia gasification. Furnace and magnetic materials, gas furnace materials, high-temperature industrial furnace supporting facilities materials.


Production Equipment
