As an important refractory, sleeve brick is widely used in high-temperature industry, especially in steel, glass, aluminum and other industries. The following are the specific applications of sleeve bricks in different high-temperature industrial fields:

I. Steel industry

Sleeve bricks are widely used in iron and steel industry, mainly used in key parts of continuous casting system:

Lining of continuous casting ladle: sleeve brick is used to protect the metal mandrel in ladle, prevent the corrosion of high temperature molten steel and slag, and control the flow of molten steel at the same time.

Protection of tapping hole: sleeve brick is used for tapping hole, which can withstand the erosion of high temperature molten steel and prolong the service life of equipment.

Ladle seat brick and nozzle brick: sleeve brick and nozzle brick are used together to control the flow and direction of molten steel and ensure the stability of continuous casting process.

II. Glass industry

In the process of glass manufacturing, sleeve bricks also play an important role:

Discharge port of glass furnace: sleeve brick is used for the discharge port of glass furnace, which can withstand the erosion of high-temperature glass liquid and ensure the stable outflow of glass liquid.

Bottom and wall of glass tank kiln: Sleeve brick is used to build the bottom and wall of glass tank kiln, and its high corrosion resistance and thermal shock resistance enable it to be used for a long time in high temperature environment.

III. Aluminum industry

In the process of aluminum smelting, sleeve brick is also indispensable:

Aluminum smelting furnace bottom: sleeve brick is used at the bottom of aluminum smelting furnace, which can resist the corrosion of aluminum liquid and its oxides and protect the furnace bottom structure.

Lining of high-temperature induction furnace: sleeve brick is used for lining of high-temperature induction furnace to protect the furnace body from high-temperature aluminum liquid corrosion.

IV. Other high-temperature industrial fields

Sleeve bricks are also widely used in other high-temperature industrial fields:

Metallurgical heating furnace and soaking furnace: sleeve brick is used at the discharge port of these furnaces and can withstand mechanical impact and chemical erosion in high temperature environment.

Discharge port of calcium carbide furnace: sleeve brick is used for the discharge port of calcium carbide furnace, and its high wear resistance and erosion resistance enable it to be used for a long time in harsh environment.

V. Summary

Sleeve brick plays an irreplaceable role in high-temperature industry. Its high fire resistance, corrosion resistance, thermal shock resistance and wear resistance enable it to protect equipment, prolong service life and ensure the stability and efficiency of production process under extreme conditions. With the continuous development of high-temperature industrial technology, the application scope of sleeve brick will be further expanded.
