48% 55% 65% Al2O3 High-Al fire bricks wedge shaped for Steel industry
High Alumina refractory 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.
High Alumina refractory brick has relatively high physical properties: with its refractoriness above 1700℃, have high thermal stability, high strength, good slag resistance, good volume stability, low creep rate etc.
High Alumina refractory bricks are widely used in industries of blast furnace, hot blast stove, electric furnace, glass furnace etc.
