The bulk density of HFK series lightweight heat-insulating brick is 0.6~1.25g/cm3. Working temperatures range from 1300??? to 1600??? . Each grade of products has unique design to meet different thermal, physical and chemical demands.GM series lightweight heat-insulating bricks are made from good quality and super-pure raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of manufacture.Each face of the brick is machined to the required accurate size.this material profitable by lessening fuel costs, construction costs and reducing the amount of time spent in the high temp furnace.
Features Of Insulating Brick
- Lower thermal conductivity
- Lower bulk density

Insulating refractory brick (IRB) is the term used for heat insulating bricks and covers those heat insulating materials which are applied up to 1000 deg C. IRBs are often mistakenly referred to as rear insulation materials. These bricks are assigned to the group of lightweight refractory bricks and are manufactured on the basis of naturally occurring lightweight raw materials.
IRB is a class of brick, which consists of highly porous fireclay or kaolin. IRBs are lightweight, low in thermal conductivity, and yet sufficiently resistant to temperature to be used successfully on the hot side of the furnace wall, thus permitting thin walls of low thermal conductivity and low heat content. The low heat content is particularly important in saving fuel and time on heating up, allows rapid changes in temperature to be made, and permits rapid cooling. IRB is characterized by the presence of large amount of porosity in it. The pores are mostly closed pores. The presence of porosity decreases the thermal conductivity of the insulating bricks.

Mullite insulation brick holds special grade mullite (3Al2O3•2SiO2) as the major crystal phase. The content of alumina in mullite insulating brick is 42%-72%. The service temperature could be 1250 -1600 .
Performance Characters:
1.High porosity.
2.Small volume density.
3.Good insulation effect.
4.High mechanical intensity.
5.Small thermal conductivity.
Application:
Mullite insulating brick is widely used in different types of high temperature furnaces or kilns. For example, it is widely used for hot-blast furnace, regenerative chamber of glass melting furnace, ceramic kiln, blind angle furnace lining of petroleum cracking system, shuttle kiln, roller kiln and petrochemical burning pits and so on.
