High alumina brick is a kind of refractory material, and the main component of this refractory brick is Al2O3.
1, refractoriness. High alumina brick refractory clay brick and brick than refractoriness to high, up to 1750~1790 DEG C, which belongs to high-grade refractory materials.
2, load softening temperature. Because of the high Al2O3 high aluminum products, low impurity content, the formation of fusible vitreous body less so than the clay brick high load softening temperature.
3, slag resistance. High alumina brick Al2O3 more, close to the neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkaline slag resistance than acid resistant slag ability is weaker.
We can also supply the high alumina brick, insulating brick, alumina ceramic roller etc. Welcome to contact us.
