The bulk density of GM series lightweight heat-insulating brick is 0.6~1.25g/cm3. Working temperatures range from 900℃ to 1600℃ . Each grade of products has unique design to meet different thermal, physical and chemical demands.GM series lightweight heat-insulating bricks are made from good quality and super-pure raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of manufacture.Each face of the brick is machined to the required accurate size.this material profitable by lessening fuel costs, construction costs and reducing the amount of time spent in the high temp furnace.
Features Of Insulating Fire Bricks
Lower thermal conductivity
Lower bulk density
