48% 55% 65%Al2O3 Standard Slag resistant High Alumina Fire brick for hot blast stove
High alumina Fire brick, alumina content above 48%, is a kind of aluminosilicate refractories. Bauxite and other raw materials with high aluminum content are calcined and shaped into high alumina bricks. High alumina brick belongs to aluminosilicate refractories. The main mineral composition of such products is aluminum oxide, mullite and corundum. High alumina brick has relatively high physical properties.
High alumina Fire brick, with its refractoriness above 1700℃, have high thermal stability, good slag resistance,high strength, good volume stability, low creep rate etc.
High alumina bricks are widely used in industries of blast furnace, hot blast stove, electric furnace, refining furnace and glass furnace and so on.
