Product Description

 

Product Description

 

The bulk density of JM series lightweight heat-insulating brick is 0.6~1.25g/cm3. Working temperatures range from 1300ºC to 1600ºC . 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.
