Acid Resistant Brick
CMAX firebricks are classified under temperature between 1300℃ to 1700℃, manufactured from high purity alumina clay.
Insulation bricks are classified under temperature between 1300ºC and 1700ºC, manufactured from high purity alumina clay by mixing, press-forming, drying, sintering and machining. Bricks contain carefully-graded organic fillers which are burned out during sintering to give a uniform controllable pore structure. This technique makes product feature low thermal conductivity and excellent heat insulation.
Refractory Insulation brick 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, cement and oil fired electric power generating plants.
Features
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 are available upon request
Application
Ceramic shuttle kilns
Metal heat treatment furnaces Steel billet reheating furnaces Oil refinery heaters
Laboratory furnaces
Our insulating bricks mainly include fireclay insulating brick, high alumina insulating brick, mullite insulating brick etc.
