Product Description GENERAL INFORMATION: High alumina firebricks are classified according to alumina content ranging from *8% to *5%, manufactured from such mineral as bauxite, corundum, etc. By mixing, press-forming, drying, sintering and machining. High alumina bricks feature stable mechanical strength and good thermal shock resistance, with high refractoriness of no lower than ***0ºC. They are commonly used as refractory lining exposed to heat directly or backup insulation linings in various types of industrial kiln or laboratory furnace. ADVANTAGES: 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 reques APPLICATIONS: Blast furnace Hot-blast stove Annealing furnace Laboratory furnace Cement kiln Electric stove roof and ladle backup layer TECHNICAL DATA: Item: GL*8 GL*5 GL*5 RL*5 RL *5 RL *5 RL *8 Al2O3 &#***5;%: *8 *5 *5 *5 *5 *5 *8 Fe2O3 &#***4;%: 2 2 2 xxxxx.
