Silicon brick is a kind of high-performance refractory material, which is widely used in many high-temperature industrial fields because of its excellent refractoriness, acid corrosion resistance and volume stability. The following are the main application industries of silicon bricks:

I. Coking industry

Coke oven: Silicon brick is the main refractory material for the bottom, wall and top of coke oven. Coke oven running at high temperature needs to withstand the double tests of high temperature and chemical erosion. Silicon brick has high refractoriness (usually ≥1650℃) and good resistance to acid slag corrosion, which makes it an ideal material for coke oven.

Application advantages: Silicon brick can effectively prevent the damage of the internal structure of coke oven, prolong the service life of coke oven and reduce the maintenance cost.

II. Glass industry

Glass melting furnace: In the process of glass production, the glass melting furnace needs to operate at extremely high temperature (usually above 1500℃) and needs to remain stable for a long time. The high refractoriness and low thermal expansion rate of silicon brick make it an ideal choice for glass melting furnace.

Application advantages: Silicon bricks can withstand the erosion of high-temperature melt, while maintaining the structural stability of the furnace and ensuring the continuity of glass production and product quality.

III. Steel industry

Hot-blast stove: Hot-blast stove is an important equipment to provide high-temperature hot air in iron and steel production, which usually needs to run at a high temperature of 1000℃-1300℃. Silicon brick can withstand the impact of high temperature flame while maintaining its structural integrity.

Application advantages: the high refractoriness and good thermal stability of silicon brick are helpful to improve the thermal efficiency of hot blast stove and reduce energy consumption.

IV. Ceramic industry

Tunnel kiln: Tunnel kiln is a kind of continuous high-temperature sintering equipment, which is widely used in the sintering process of ceramics, refractories and other industries. Silicon brick can withstand high temperature and chemical erosion in tunnel kiln, while maintaining the structural stability of kiln body.

Application advantages: the volume stability of silica brick is helpful to improve the service life of kiln body and reduce the maintenance cost of equipment.

V. Non-ferrous metal smelting industry

Smelting furnace: In the process of smelting nonferrous metals, such as copper, aluminum, zinc and other metals, refractory materials are needed to protect the furnace body. The resistance of silicon brick to acid slag erosion makes it an ideal material for nonferrous metal smelting furnace.

Application advantages: Silicon brick can effectively prevent the corrosion of slag on furnace wall, reduce the maintenance cost of equipment and prolong the service life of furnace body.

VI. Chemical industry

Acid reaction furnace: In chemical production, some acid reaction furnaces need refractory materials to resist the corrosion of acid substances. The acid corrosion resistance of silicon brick makes it widely used in these equipments.

Application advantages: Silicon brick can effectively prevent the corrosion of acid substances to the furnace body and ensure the stable operation of the equipment.

VII. Building materials industry

Cement kiln: In the process of cement production, the cement kiln needs to run at high temperature and bear chemical erosion. The high refractoriness and corrosion resistance of silicon brick make it have a good application prospect in cement kiln.

Application advantages: Silicon brick can effectively prolong the service life of cement kiln and reduce the maintenance cost of equipment.

VIII. Other high-temperature equipment

Ceramic fiber furnace: In the process of ceramic fiber production, high temperature furnace needs refractory materials to protect the furnace body. The high refractoriness and low thermal expansion rate of silicon brick make it an ideal choice for ceramic fiber furnace.

Application advantages: Silicon bricks can effectively withstand high temperature and chemical erosion, ensuring the stable operation of equipment.

IX. Summary

Silicon bricks are widely used in many high-temperature industrial fields such as coking, glass, steel, ceramics, nonferrous metal smelting, chemical industry, building materials and so on because of their excellent refractoriness, acid corrosion resistance and volume stability. It plays a key role in these industries, which can effectively prolong the service life of equipment, reduce maintenance costs and improve production efficiency.
