1, high fire resistance. The refractoriness of high alumina brick is higher than that of clay brick and semi-silicon brick, up to 1750ºC ~ 1790ºC;
2. High softening temperature under load. High aluminum brick (AI2O3) content is high and less impurities, so the load softening temperature is higher than clay brick;
3, excellent slag resistance. High aluminum brick (AI2O3) content is high, so it is close to neutral refractory material, which can be corroded by acid and alkaline slag, but high aluminum brick also contains SiO2, so the alkali slag is weak than the acid slag.
4, weak acid slag.
Company main products and profiles:
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
