General Information of Insulating Fire Brick GJM23
Insulating fire bricks GJM23 are made from high purity alumina and low iron content raw materials. The insulating fire bricks are produced by mixing, casting or extruding, drying, sintering and grinding. Our insulating fire bricks GJM23 temperature is 1260℃(2300℉). A variety of type could be done according to customer’s request.
To make our firebricks more energy and cost effective, we have different manufacturing methods for our insulating fire bricks casting and extruding method.
For insulating fire bricks GJM23,we choose the casting methord.The casting insulating fire bricks offering the lowest density, the lowest thermal conductivity for the application above 1000℃.
Characteristics of Insulating Fire Brick GJM23
Our insulating fire bricks exhibit the following characteristics:
Light weight and low thermal conductivity allows thinner furnace walls
Low heat storage results in rapid cooling and heating operation
Low iron and impurities to enhance reducing atmosphere
Typical Application of Insulating fire bricks GJM23
Ceramic shuttle kilns
Oil refinery heaters
Laboratory furnaces
Backup insulation for all furnaces
