In addition, refractory bricks are also suitable for use in lining furnaces, kilns, combustion chambers and other high-temp equipment. Made from high quality refractory raw materials, Kerui refractory bricks play a key role in the heart of various high temperature industries.
What are Refractory Bricks Used for?
The uses of high temperature refractory bricks are wide due to their unique performance. They mainly have wide applications in the lining and construction of furnaces and reactors in industries such as steel, cement, glass, ceramics, and petrochemical. Kerui refractory bricks can withstand extreme temperatures and harsh working environments, to ensure the safety and efficiency of these key industrial processes. Overall, refractory bricks play a critical role in enabling vital industrial processes and applications across various sectors.
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.
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.
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.
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.
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.
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.
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:
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.
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.
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.
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.
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.
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 Bricks 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.
- Mechanical Strength: Refractory bricks maintain their mechanical strength and structural stability even if exposed to extreme temperatures and chemical reactions. So it provides long-lasting, reliable performance in demanding industrial environments.
- Thermal Conductivity: Due to the low thermal conductivity of the cheap refractory brick, it reduces the heat transfer through the lining material. This property facilitates the prevention of overheating from reaching the furnace shell, to protect the equipment.
- Customizability: Kerui Refractory bricks can manufacture in a variety of shapes and sizes to suit the specific needs of different applications. So Kerui can offer customized services to accommodate complex furnace designs and configurations.
