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℃.
General Information of Insulating Fire Brick GJM26
Insulating fire brick GJM26 are produced by mixing, casting or extruding, drying, sintering and grinding. Our insulating fire bricks GJM23 temperature is 1430℃(2600℉). We could supply a wide range of shapes.
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 GJM26,we choose the extruding method. Extruding insulating fire bricks have better strength and offering great performance in load bearing applications and in conditions where abrasion from mechanical abuse or flow of hot gases.
General Information of Insulating Fire Brick GJM28
