High alumina firebricks are classified according to the alumina content which is from lowest 48% to highest 95%, manufactured from mineral of bauxite, corundum, etc. by mixing, press-forming, drying, sintering and machining... High alumina firebricks are classified according to the alumina content which is from lowest 48% to highest 95%, manufactured from mineral of bauxite, corundum, etc. by mixing, press-forming, drying, sintering and machining. High alumina bricks feature stable mechanical strength and thermal shock resistance, with high refractoriness of no lower than 1880℃, High alumina bricks are commonly used as refractory lining exposed to heat directly or backup insulation linings in various types of industrial kiln or laboratory furnace. Advantages of NR high alumina firebricks Low thermal conductivity -High refractoriness -Excellent acid and base slagging resistance -Excellent thermal shock resistance -Excellent mechanical strength -Non standard sizes and shapes are available upon request. Applications of high alumina firebricks Blast Furnace -Cement Rotary Kiln -Lime Calcination Kiln – Glass Tank Furnace -Anode Baking Furnace -Anode Baking Furnace -Blast Furnace Hearth -Glass Tank Furnace -Anode Baking Furnace -Blast Furnace Stove -Blast Furnace Bottom – Blast Furnace Stove Checkers -Secondary Steel-making Vessel- Chemical, Petrochemical and Fertilizer -Secondary Steel-making Vessel -Chemical, Petrochemical and Fertilizer -Secondary Steel-making Vessel
