Product Description
Insulating fire clay 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.
Advantages of our light weight fireclay insualting brick(YZFC-IFB):
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
Two type of our Alumina Insulating Fire Brick (LG-IFB):
Ordinary type (PLG-IFB)
Low iron type (DLG-IFB)
Two produce methods of our LG-IFB:
Fast foam setting technology
Method of burning up adding object
Characteristics of our LG-IFB:
High cold crushing strength
High softing temperature under load
Accurate dimension
Good thermal shock resistance
Application:
Widely used in insulating layers of various thermal equipments and linings where no high temperature melt corrosion occurs.
