High alumina brick is one of refractory materials. The main component of this refractory brick is Al2O3.
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
Al2O3 in high alumina brick is close to neutral refractory, and it can resist acid slag and alkaline slag erosion.
