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
- Light weight character
- Lower creep rate in high temp
- Good thermal shock resistance performance
- Higher temperate resistant with good refractoriness
Applications Of Insulating Brick
The refractory linings of hot surfaces or backing heat-insulating layers of other refractory materials. The refractory linings or heat-insulating materials of the industrial furnaces in the petroleum or chemical industries , such as , ethylene pyrolysis furnaces, tubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high-temperature shuttle kilns, etc.

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.

Cold Face Insulation brick is a lightweight insulating material with SiO2 above 67% and bulk density below 1.2g/cm3. The refractoriness and softening temperature under load are not much different from ordinary silica bricks with the same composition. However, due to the large number of pores, the compressive strength, slag resistance and corrosion resistance are not as good as ordinary silica bricks, but the thermal shock resistance is improved. Cold Face Insulation bricks use finely divided silica as raw materials, and the critical particle size is usually not more than 1mm, and the particles smaller than 0.5mm are not less than 90%. Add flammable substances to the ingredients or use the gas generation method to form a porous structure, which is obtained by firing. Can also be made into non-fired products. It is mainly used in various parts of the kiln that require heat insulation or weight reduction without direct contact with the melt, without the action of corrosive gases, and without sudden temperature changes. Use at high temperature and cannot contact with alkaline refractory materials. According to different materials, the maximum operating temperature is 1200 .
Mainly used for Back up Lining hot blast furnace top, blast furnace stack and bottom, glass furnace regenerator, ceramic sintering kiln, dead corner lining of petroleum cracking system,ethylene pyrolysis furnaces, tubular furnaces,reforming furnaces of synthetic ammonia,gas generators,linings or heat-insulating materials of the industries,etc.
Performance:
- Strong resistance to acid erosion.
- Good thermal shock resistance.
- High resistance to wear.
- Resistance to spalling.
- Complete monolithic refractory.
- Easy to construct..
