Description

Product Specifications: 230*114*65mm

High alumina bricks are close to neutral, can resist acidic and alkaline corrosion, have high refractory degree and high load softening temperature, and are widely used refractory bricks at present.

High alumina brick is a kind of refractory material, and the main component of this refractory brick is Al2O3.

characteristic

A, fire resistance

The refractoriness of high-alumina bricks is higher than that of clay bricks and semi-silica bricks, reaching 1750~ 1790 ° C, which is an advanced refractory material.

B. Load softening temperature

Because of the high Al2O3 in high aluminum products, less impurities, and less fusible glass body, the load softening temperature is higher than that of clay bricks, but because mullite crystals do not form a network structure, the load softening temperature is still not as high as that of silica bricks.

C. slag resistance

There is more Al2O3 in high alumina brick, which is close to neutral refractory material, and can resist the erosion of acid slag and alkaline slag. Because it contains SiO2, the ability of alkaline slag resistance is weaker than that of acid slag.
