Uses of Refractory Bricks in Different Industries

Refractory bricks have a wide range of applications in many high-temp industries because of their excellent high temperature resistance and corrosion resistance. They play an important role in modern industry. The following is about the application of refractory brick in high-temp industries.

Refractory Bricks Used for Petrochemical Industry

Refractory Bricks Used for Iron Steel Industry

Uses of Refractory Bricks in Steel Industry

In the steel industry, refractory bricks are suitable for use in the construction of blast furnaces, hot blast furnaces and ladles. These bricks are arranged on the inner walls of the blast furnace. During the smelting of iron ore, they withstand temperatures in excess of 1600°C (2912°F). Their ability to withstand high temperatures and chemical reactions ensures efficient iron production.

Uses of Refractory Bricks in Aluminum Industry

Refractory bricks are often appropriate for aluminum smelting in the lining of electrolytic cells for the extraction of aluminum. These bricks provide insulation and chemical resistance to highly reactive electrolytes and molten aluminum at temperatures in excess of 900°C (1652°F). In addition, refractory bricks are used in holding furnaces and crucibles for metal casting in the aluminum industry.

Uses of Refractory Bricks in Cement Industry

In the process of cement production, refractory bricks play an important role, especially in the sintering area of rotary kiln and cement kiln. These bricks isolate and protect the inner walls of the kiln, where heat the raw material to temperatures of around 1450°C (2642°F) to produce clinker. Meanwhile, the heat resistance of the bricks contributes to energy-efficient cement production.

Uses of Refractory Bricks in Glass Industry

Glass manufacturing depends on refractory bricks as linings for melting furnaces, tank furnaces and heat storage furnaces. This type of brick allows for the continuous production of glass at temperatures above 1600°C (2912°F) because it provides insulation and prevents the molten glass from being contaminated by the furnace materials.

Uses of Refractory Bricks in Petrochemical Industry

Kerui Refractory bricks play a vital role in the petrochemical sector. These bricks are suitable for cracking furnace lining that produces ethylene, propylene and other important petrochemical products. These refractory bricks can withstand temperatures above 800°C (1472°F) and harsh chemical reactions, to ensure a safe-cracking production and the longevity of heat equipment.

Uses of Refractory Bricks in Power Industry

In the field of power generation, refractory bricks have wide usage in boilers and furnaces where they line the combustion chambers to provide thermal insulation. The high temperature and thermal shock resistance of these refractory bricks help in maintaining efficient energy conversion and contribute to the smooth operation of power plants.

Uses of Refractory Bricks in Furnaces

Many industries use refractory bricks in various parts of the furnace to withstand high temperatures, protect the furnace structure, and ensure efficient heat transfer. Let’s see the uses of refractory bricks in the furnace:

Uses of Refractory Bricks in Furnace

Used for Heating Area (Furnace Chamber)

The main heating area or furnace chamber can use refractory bricks. Meanwhile, this lining acts as a protective barrier against extreme temperatures and chemical reactions that occur during the heating process. Refractory bricks have excellent insulating performance. So it can prevent heat loss from the furnace and maintain the required high temperatures needed for industrial processes.

Used for Burners

Refractory bricks are appropriate in the construction of burner blocks in furnaces. The burner block provides a stable base for the burner. The burner is responsible for introducing the fuel and air (or oxygen) required for combustion. The bricks in this area must be resistant to high temperatures and chemical attacks in order to withstand the working conditions of the combustion process.

Used for Regenerators

Regenerative furnaces use refractory bricks in the regenerator chambers. The regenerators alternate between storing heat from the exhausted flue gases and preheating the incoming combustion air. The uses of refractory bricks here must have good thermal and conductive properties to transfer and store heat efficiently.

Used in Doors and Openings

Furnaces have doors or openings for loading and unloading the materials. Refractory material suppliers bricks are appropriate in the lining of furnace doors and openings to form effective seals. These seals prevent excessive heat loss during operation and ensure a safe working environment for the furnace operator.

Used in Stack or Chimney

In some cases, refractory bricks are suitable for use in the construction of chimneys or stacks. These bricks provide insulation and protect the structural integrity of the chimney. Chimneys are under hot flue gases during venting, so the excellent properties of refractory bricks extend the life of the chimney.

Used in Cooling Systems

The cooling system of the furnace can protect sensitive components. In certain high-temperature furnaces, such as steel-making, refractory bricks are suitable for use as part of the cooling system. These bricks help to cool specific furnace components and prevent damage caused by extreme heat exposure.

Why are Kerui Refractory Products Widely Used?

Kerui Refractory bricks are widely used for various industrial applications due to their unique properties that make them indispensable in high-temp and harsh environments. The key reasons for refractory bricks uses are as follows:

  • High Temperature Resistance: Refractory bricks can withstand extreme temperatures. Besides, they can also withstand hundreds to thousands of degrees. This makes them suitable for use in industries such as steel, cement, glass and ceramics.
  • Chemical and Corrosion Resistance: These bricks have excellent resistance to chemical and harsh corrosive environments. This property is essential in industries where corrosive properties are present, such as in the production of chemicals, petrochemicals and metallurgical processes.
  • Thermal Insulation: Its excellent insulation properties help to maintain high temperatures within industrial furnaces and prevent heat loss. This property is essential to ensure energy efficiency and cost-effectiveness in high-temperature processes.
