Insulating Brick: An Excellent Product Used To Reduce Heat Loss And Maximize Heat Conservation Within Various Industrial Kilns And Furnaces

Posted by Admin on June, 17, 2019

Insulating bricks are the soft bricks having low thermal conductivity and high porosity, used to reduce heat loss and thus to maximize heat conservation within the furnace. These insulating bricks are made up of high-temperature resistant material which has been foamed while wet. When the bricks are made, the entrapped air provides excellent insulation. Generally, Insulating bricks are soft and light in weight and can be easily cut by any handled tool. These bricks have come in normally brown, white or light brown shades.

Most of the insulating bricks are produced from high-purity refractory clay with granulated additions of alumina and are ideal for the higher temperature-rated products. These bricks are suitable for applications at service temperatures ranging from 1250 degree Celsius to 1850 degree Celsius and can be directly exposed to combustion and flame products. These bricks exhibit a unique combination of chemical, mechanical stability, and insulating properties. These bricks are often used in lining furnaces, and pottery kilns to make them more efficient.

Insulating brick exporters bring forth a wide range of insulating bricks including high alumina insulating bricks or high alumina heat insulating bricks that are used in various industrial applications. The high alumina insulating bricks are the new type of lightweight insulating material which contains approximately 48% alumina, mullite and glass phase or corundum. These lightweight alumina insulating bricks adopt inorganic matter as ignition loss substance so as to increase the porosity of refractory. They have advantages like high porosity, good insulation effect, small volume density, high mechanical intensity, small thermal conductivity, and long service life. For several industrial kilns and furnaces, these bricks are a kind of essential refractory for energy saving and temperature preservation.

Some of the features of insulating bricks are as follows: -

The insulating bricks have very high refractoriness and structural strength.

These bricks have low thermal conductivity and provide excellent good thermal insulation that enables the use of thin-walled constructions.

They have high resistance to reducing atmosphere.

They have uniform pore size and distribution.

They are durable in nature.

They have low heat storage and absorb minimal heat ensuring energy savings in cyclically- operated kilns.

They contain low iron and alkali flux content.

Applications of insulating bricks: -

The insulating bricks are extensively used in industries like-

Furnaces

Glass industry

Concast plants

Rolling Mills

Forging units

Auto parts industry

Hand tool industry

Kilns

Chimneys

Flues and buck stays

Boilers in thermal power stations

Cold storage walls

Hot gases beds in coke oven batteries of steel plants

Petrochemical industry

Machinery industry

Ceramic industry

Carbon black stove, gasifier, hydrogen manufacturing furnace, and shuttle kiln, etc.
