High Alumina fire brick, the Al2O3 content is above 48%, which is a kind of aluminosilicate refractories. Bauxite and other raw materials with high aluminum content are calcined and shaped into high alumina bricks. The main mineral composition of such products is aluminum oxide, mullite and corundum.
They are widely used in steel industry of blast furnace, hot blast stove and other industrial kilns.
High Alumina fire brick has relatively excellent physical properties:
1, High refractoriness, its refractoriness is above 1700℃,
2, High thermal stability, and high strength,
3, Good slag resistance
4, Good volume stability
4, Low creep rate etc
