How Much Do You Know About Insulation Bricks?

Whether you need to insulate a commercial building or your home, there are a variety of insulation materials that can help you keep the heat in so that the room stays warm and comfortable. Often referred to as refractory bricks, they are one of the most common types of insulating refractory bricks and are widely used in high temperature environments, such as burners and kilns.

Due to their high thermal conductivity, insulating bricks are used in furnaces and kilns.

In addition, these refractory bricks are suitable for high temperature environments because they require the least amount of energy.

On average, refractory insulating bricks offer many advantages. On the other hand, choosing the ideal refractory brick can be tricky.

Therefore, in this blog, we will discuss how to choose the best insulating bricks. Read on!

The kind of brick that will perform great for you will be determined solely by the application. Here are three categories and their applications.

Super-Duty Firebricks

In extremely high temperatures, super-duty firebricks are employed for insulation material. Most super-duty firebricks are constructed of silica, which is extremely robust and heat resistant. Numerous sorts of super-duty bricks are used in industries such as the glass and steel industries.

High-Alumina Firebrick

Because of their corrosion resistance and efficiency in high-temperature burners, high-alumina firebricks are a great replacement. They’re employed in and around blast furnaces, concrete, limestone, ceramics kilns, and glass tanks, among other places. Refining, petrochemical, and refractory sectors all employ high-alumina firebricks.

Lightweight insulating firebricks are being used in cold weather. Unlike other refractories, they do not absorb heat. They can, though, be utilized to retain surrounding heat furnaces.

List of applications for insulating bricks

Metallurgy: Blast furnace, hot blast stove, reheating furnace, etc.

Petrochemical: Ethylene cracking furnace, primary reformer furnace, reheating furnace, hydrogen production furnace, etc.

Ceramics: Roller kiln, pusher kiln, etc.

Glass: Glass furnace regenerator, etc.

Carbon: Carbon roaster, etc.

Principles for selecting insulation bricks include.

1) It should not affect the service life of the entire refractory masonry.

2) For continuously working high temperature furnaces, it is generally reasonable to insulate a large area to reduce heat loss. However, for some special areas, such as the roof of an open-air furnace, insulation can reduce the service life. For furnaces that work periodically, regenerative heat loss is a major factor in heat loss. Insulation can increase the temperature of the masonry and increase the regenerative heat loss. Therefore, whether a regularly working furnace should be insulated is determined after calculating the regenerative and heat losses.

3) Due to their high porosity, insulated bricks cannot be subjected to excessive loads and cannot come into direct contact with molten metal, slag and high temperature dust.

4) The strength of the insulated bricks is low. Brick joints and expansion joints should be properly handled to avoid damage caused by volume expansion. Insulated refractory bricks should not be subjected to strong mechanical vibration, impact and friction.

5) Due to the large linear shrinkage of the insulated bricks after reheating, the maximum working temperature should be 100 degrees lower than the firing temperature.

It is also important to choose the best supplier of insulated refractory bricks.

It is vital that you choose the best insulated bricks for your project, regardless of their use. While this information may help you choose the right blocks, you should always consult an expert to ensure that you are using the right blocks.

Choosing the right brick supplier is just as important as choosing the right insulation bricks. Choosing refractory bricks is easy when you choose the right refractory manufacturer.

While we hope you find this information useful, we recommend that you consult a specialist refractory company in India to ensure that you get the desired results.
