INSULATING FIREBRICK

GJM insulating firebrick is classified under temperature between 1300 to 1700, manufactured from high purity alumina clay by mixing, press-forming, drying, sintering and machining. Brick contains carefully-graded organic fillers which are burned out during sintering to give a uniform controllable porous structure. This technique makes product feature low thermal conductivity and excellent heat insulation.

GJM insulating firebrick can be used as a hot face lining directly exposed to the heat or as a backup insulation layer in iron and steel mills, non-ferrous foundries, petrochemical,
ceramic, glass and oil fire.

ADVANTAGES

* Light weight and low thermal conductivity allows thinner furnace walls;

* Maintain stable structural strength throughout ambient to maximum service temperature;

* Low heat storage results in rapid cooling and heating operation;

* Low iron and impurities to enhance reducing atmosphere;

* High thermal shock resistance in preventing spalling;

* Non standard sizes and shapes available upon request;
