In the field of high-temperature industrial production, the ability to withstand extreme environments and ensure stable equipment operation directly determines production efficiency and corporate benefits. Corundum Bricks, with their outstanding performance, have become an indispensable core material in numerous high-temperature industries. Their applications cover key sectors such as metallurgy, petrochemicals, and building materials, providing strong support for the safe and efficient operation of industrial production.
I. Metallurgical Industry: A "Solid Defense Line" for Metal Smelting
Equipment in the metallurgical industry, such as blast furnaces, hot blast stoves, and steel rolling heating furnaces, operates in environments characterized by high temperatures, high pressure, severe wear, and chemical corrosion for long periods. This places extremely strict requirements on refractory materials. Corundum Bricks, with their high refractoriness (capable of withstanding temperatures above 1800℃ at maximum), high strength, and excellent slag resistance, are the ideal choice for such equipment.
In the blast furnace lining, Corundum Bricks can effectively resist the erosion and scouring of molten iron and slag, preventing premature damage to the lining and extending the service life of the blast furnace. As the "heart" of the blast furnace, the hot blast stove needs to continuously supply high-temperature hot air. The excellent thermal insulation performance and stability of Corundum Bricks ensure uniform and stable temperature inside the hot blast stove, reduce heat loss, increase the temperature of the hot air, and thereby improve the smelting efficiency of the blast furnace. In addition, in steel rolling heating furnaces, Corundum Bricks can withstand the high-temperature impact and friction during the heating of steel billets, ensuring the integrity of the furnace structure, maintaining the continuous operation of steel rolling production, and reducing equipment maintenance costs.
II. Petrochemical Industry: A "Safety Barrier" for Reaction Equipment
Core equipment in the petrochemical industry, including gasifiers, carbon black reactors, and cracking furnaces, involves high-temperature chemical reactions during production, and most of the media are highly corrosive. This imposes high demands on the temperature resistance and corrosion resistance of refractory materials. Corundum Bricks, with their excellent high-temperature resistance and chemical erosion resistance, provide reliable protection for such equipment.
In gasifiers, raw materials undergo gasification reactions under high temperature and high pressure, with temperatures reaching above 1500℃, and corrosive gases containing sulfur and dust are generated. Corundum Bricks can effectively resist the scouring and corrosion of high-temperature gases, prevent damage to the furnace wall, avoid safety hazards such as gas leakage, ensure the stable progress of the gasification reaction, and provide stable raw materials for the subsequent production of ammonia, methanol, and other products. Inside carbon black reactors, hydrocarbons undergo pyrolysis at high temperatures to produce carbon black. The high density and wear resistance of Corundum Bricks can reduce the adhesion of carbon black on the furnace wall, lower the frequency of furnace cleaning, and at the same time withstand temperature fluctuations during the high-temperature pyrolysis process, ensuring the long-term stable operation of the reactor and improving the output and quality of carbon black.
III. Building Materials Industry: An "Efficient Assistant" for Kiln Production
Equipment in the building materials industry, such as glass kilns and cement rotary kilns, is crucial for the production of building materials like glass and cement. Their operating environment is high-temperature and accompanied by the erosion of molten materials. Corundum Bricks play an important role in such equipment due to their excellent performance.
The melting tanks and runners of glass kilns are in long-term contact with high-temperature molten glass, with temperatures reaching above 1600℃, and the molten glass has strong corrosiveness. Corundum Bricks can resist the erosion and penetration of molten glass, prevent nodulation and material leakage of the kiln body, ensure the purity and quality of the molten glass, and at the same time extend the service life of the glass kiln, reduce downtime for maintenance, and improve glass production efficiency. In the burning zone of cement rotary kilns, temperatures can reach above 1400℃, and the kilns are subject to wear and chemical corrosion from cement clinker. The high strength and slag resistance of Corundum Bricks can withstand the scouring and erosion of clinker, maintain the roundness and structural stability of the kiln body, ensure the burning quality of cement clinker, and increase cement output.
IV. Other High-Temperature Fields: A "Reliable Choice" for Special Scenarios
Beyond the above-mentioned major industries, Corundum Bricks also have wide applications in special high-temperature scenarios such as waste incinerators and ceramic sintering kilns. When waste incinerators handle waste, high-temperature flue gas and corrosive substances are generated. Corundum Bricks can resist high temperatures and corrosion, prevent damage to the furnace wall, and ensure the safe and environmentally friendly operation of waste incineration. Ceramic sintering kilns require precise control of the high-temperature environment to ensure the sintering quality of ceramic products. The excellent thermal insulation performance and temperature stability of Corundum Bricks can help the kilns maintain a uniform high-temperature atmosphere and improve the yield and quality of ceramic products.
