What Do You Know About Fire Insulate Bricks

Refractory bricks are used as a means of reflecting heat back to the combustion chamber, so that the heat can be circulated in the stove and released into the room in a controlled environment.

When you remember that the temperature in the stove may exceed 400 ° C, we are talking about extreme temperatures. Fire insulation bricks manufacturers make bricks that are made of materials that reflect heat, while the outside of the refractory bricks will remain extremely cold.

It’s important to protect the stove from extreme temperatures. These bricks are used for this purpose too.

When exposed to such extreme temperatures, even the strongest cast iron stoves wear out relatively quickly. According to general experience, in the combustion chamber, when the temperature in the combustion chamber is 400 ° C.It is equivalent to about 250 ° C in the flue when the flue gas is released.

Therefore, even after cooling, the gas flowing from the flue into the atmosphere begins to fly at a temperature of 250 ° C!

Once you find any signs of general wear on the refractory bricks, they should be replaced immediately regardless of their size.

When the refractory bricks are damaged, not only will less heat be reflected back to the interior of the stove, thereby increasing the temperature, but also some parts of the stove will be exposed to high temperatures.

Generally, refractory bricks are relatively easy to install, and you can buy them from the most stocked stoves.

Fire bricks are lightweight and relatively soft They can be easily cut using any other hand tools such as a handheld hacksaw or chisel or even a drill bit. These bricks come in different colors and types; colors include white, light brown, etc.

Among the refractory materials, air is the best insulation material, which is why the insulating refractory bricks have excellent thermal insulation properties. Their bodies are composed of tiny voids similar to the honeycomb effect.

How to use fire bricks?

Lightweight firebricks are used widely in industries for gas burner, wood burning, etc. furnaces and amateur furnaces heated by furnaces, whether used for hot surface lining or external backup insulation materials.

If you’re looking for insulation bricks for sale, we have them ready and stocked.

Don't confuse lightweight insulating refractory bricks with bulky refractory bricks

Insulating bricks are also refractory materials. Of course, they can withstand a very high temperature range, but their thermal conductivity is very low and they cannot absorb heat at all.

These are the purpose of heat insulation. For example, if you use them for hot noodles used for cooking in a wood-burning oven (for cooking), the oven will not be able to cook because it will hardly store and hold any heat.

However, you can use these insulating refractory bricks on the outside (heavier refractory brick walls, vaults or under floor tiles and floors) to prevent the heat soaked in the indoor weight from escaping and achieve excellent results.

It means a well-insulated oven, which keeps the heat absorbed in its whole, so it should be cooked for a long time.
