Fire brick and its use

Definition of firebrick

Refractory brick and its use, which is produced from porcelain and refractory soils and is made with a dense and delicate molecular structure at a temperature above 1500 degrees Celsius. and industrial insulation is widely used.

Of course, its normal type is also used in brick facades of buildings today.

fireproof brick ingredients

The basic materials of Amiran refractory bricks are very special minerals and mineral pumice which are refractory. That is, they have high temperature resistance. The raw materials for the production of refractory bricks are called refractory materials, which are usually ceramic and other metal materials that can be stable at high temperatures. Have.

Use of fireproof brick in the facade of the building

With the use of refractory bricks in the facade of the building, you can be sure that the facade of your building will remain attractive and the same as the first day for future generations and your children. Of course, this is only possible in one case, and that is the use of firebricks with standard formulations and standards. Unfortunately, the market is filled with all kinds of facade bricks called refractory bricks, but they do not have the necessary quality in the long term and change color or shape after a few years of installation. Algae or dandruff, it is recommended to ask the seller for the color stability and anti-dandruff standards of the fireproof brick at the time of purchase.

Application fireproof brick

The most important feature of fireproof brick is their high resistance to heat, and this issue makes this material used as the inner lining of industrial furnaces and can even be used in fireplaces. In fact, fireproof brick can be used in spaces with high temperature. Note that there are different types of refractory bricks according to the type of material used in their compositions, and each of them can withstand different ranges of heat according to the materials used in them.

What was used to cover furnaces until the 1960s was carbon and refractory clay, but currently the use of refractory bricks in the inner lining of furnaces is very wide.

Refractory brick texture

There are different types of fireproof brick, depending on the type of material used in their compositions, they can tolerate different ranges. Until the 1960s, carbon and refractory soil were used to cover furnaces, but today, with the production of various types of refractory bricks, they are used in the inner lining of furnaces.

Silicon brick, special refractory brick, aluminum brick, alkaline refractory brick

Silicon brick

Bricks made of siliceous soil are called siliceous bricks. Of course, siliceous soils are also called quartzites, whose constituents include silicon oxide in a very large amount, and the rest are calcium oxide, titanium oxide, and iron oxide, which use pure quartz to prepare this composition. This type of refractory bricks are used for the inner lining of steelmaking furnaces. Even silica refractory bricks are used in the production of glass, ceramics, and also in coke ovens, the reason being that these types of bricks have high thermal conductivity and are impervious to gases.

Special refractory brick

These bricks are a type of refractory bricks that are made of transition metals and have special uses in the industry
Types of special refractory bricks are:

Chromium Oxide – Corundum Refractory Brick

The ingredients of this type of brick are 90 to 95 percent aluminum oxide and 5 to 10 percent chromium oxide. This brick is used in the inner part of the iron smelting blast furnace.

Zirconium refractory brick

This brick has a high heat resistance, that’s why it is mostly used in aluminum iron smelting furnaces and molten glass furnaces

Chrome oxide refractory brick

This brick has 90 to 95% chromium oxide and it is used in the furnaces of the glass industry.

Aluminum brick

The main ingredient of these bricks is aluminum oxide or aluminum, which has a suitable heat resistance up to 1750 degrees Celsius and is used in the inner lining of metal and iron smelting furnaces and large glass factories.

Alkaline refractory brick

Alkaline bricks are composed of magnesium oxide and silicon dioxide, and if they want to increase the heat resistance of these types of bricks, some chromium oxide and iron oxide are added to this mixture. The application of this type of bricks is in the inner lining of open steel furnaces, rotary cement furnaces, the upper part of glass melting furnaces, as well as the preparation of non-ferrous metal industries.

How to install refractory bricks

Note that you can use glue to install firebricks, but they can also be installed using mortar and cement. The important thing is that the design and combination of colors, as well as the combination of stone and brick, will make you present a beautiful work in the end. Note that if you use the most expensive firebrick for the facade of the building, but do not consider the proper design and composition at the time of execution, it will be useless and all the expenses you have spent will be wasted. Therefore, we recommend that you consider and implement a suitable and beautiful design for the facade of the building with the help of designers.

Among the advantages of firebrick in the exterior of the building, the following can be mentioned:

Color of refractory bricks

The most famous colors of refractory bricks are red and brown, but don’t forget that there are many color variations in refractory bricks and they can change color from black to white. Even the existence of vivid colors and the color of nature can be seen in firebricks, which creates a unique look.

The price of refractory bricks

The price of refractory bricks is higher than other bricks and the reason is the high price of fireclay. Of course, the price of refractory soil is high due to the difficulty of its production.
