Insulating Fire Brick
Insulating fire brick，also known as light weight fire brick,or IFB.Insulating fire brick is white color,light weight,widely used in kilns,forges and high temperature applications ranging from 1050C to 1760C.
Color: White
Package:Carton,Pallet
Usage:Insulation or fire lining in kiln,furnace
Overview of Insulating Fire Brick
Insulating firebricks are light weight and have good insulation properties.Insulating fire bricks are made from refractory clay and alumina.Light weight fire bricks are porous,their weight is equal to 20-25% of dense hard brick.The porous nature is the key to good insulation,and prevent heat loss,and improve the efficient in high temperature furnace.

Features
Light weight and good insulating values
Low thermal conductivity and energy efficient
Accurate size and machining
Different density to meet various insulation application
Easy of handing because of light weight
High Mullite content,stable against chemical attach and good resistance in reducing atmospheres
Application
Usually the furnace lining use different grade fire brick and refractories to as a combination. Insulating fire brick normally used as back up lining brick behind dense hard brick or castable,also could be used as fire face brick for example kilns.
Fire box in gas and electric powered kilns
Wood and oil burning kilns
Safety lining in salt kilns and other applications
Waste recovery
Incinerators
Combustion chambers
Crucible furnace
Glass and ceramic industries
