Corundum ramming mix, a high-performance refractory material composed of high-purity corundum (Al₂O₃) as the main raw material, combined with advanced bonding agents and additives, is renowned for its exceptional high-temperature resistance, wear resistance, corrosion resistance, and excellent thermal shock stability. As a key material in high-temperature industrial production, it plays an irreplaceable role in extending equipment service life, reducing maintenance costs, and improving production efficiency. Whether in metallurgy, building materials, chemicals, or other fields, corundum ramming mix has become the preferred refractory solution for enterprises pursuing high-quality and stable production.
Core Applications of Corundum Ramming Mix Across Industries
1. Metallurgical Industry: The Backbone of High-Temperature Smelting
The metallurgical sector is the largest application field of corundum ramming mix, especially in steelmaking, non-ferrous metal smelting, and ferroalloy production.
Steelmaking Equipment: It is widely used for lining and repairing electric arc furnace bottoms, ladle bottoms, tundish working layers, and tapholes. The material`s high density and strong erosion resistance can withstand the scouring of molten steel and slag, effectively preventing molten steel penetration and extending the service life of smelting equipment by 30%-50% compared to conventional refractories.
Non-Ferrous Metal Smelting: In aluminum, copper, zinc, and other non-ferrous metal smelters, corundum ramming mix is applied to the linings of blast furnaces, reverberatory furnaces, and electrolytic cells. Its excellent thermal stability adapts to the frequent temperature changes during smelting, while its resistance to chemical corrosion from molten metals and fluxes ensures the purity of the final product.
Ferroalloy Production: For ferrochrome, ferromanganese, and other ferroalloy smelting furnaces, the material`s high-temperature resistance (up to 1800℃) and wear resistance can endure the harsh working environment of high-temperature reduction reactions, reducing furnace maintenance downtime.
2. Building Materials Industry: Ensuring Stability in Kiln Operations
In the building materials industry, corundum ramming mix is essential for cement, glass, and ceramic production kilns, where it faces long-term high temperatures and material erosion.
Cement Kilns: It is used for lining the transition zone, burning zone, and tertiary air duct of cement rotary kilns. The material`s strong resistance to alkali erosion and thermal shock can effectively resist the corrosion of cement clinker and alkali metals, reducing kiln skin peeling and extending the kiln`s service cycle.
Glass Kilns: For glass melting furnaces, corundum ramming mix is applied to the bottom, side walls, and throat parts. Its high density and low porosity prevent glass liquid penetration and volatilization, ensuring the transparency and quality of glass products, while also reducing energy consumption due to its good thermal insulation performance.
Ceramic Kilns: In high-temperature ceramic sintering kilns, the material`s uniform texture and stable high-temperature performance ensure consistent furnace temperature distribution, improving the sintering quality of ceramics and reducing product defect rates.
3. Chemical Industry: Resisting Corrosion in Harsh Environments
The chemical industry often involves high-temperature, high-pressure, and corrosive media reactions, making corundum ramming mix an ideal refractory material for reactors, furnaces, and pipelines.
Chemical Reactors: For hydrogenation reactors, cracking furnaces, and other equipment, corundum ramming mix`s resistance to acid, alkali, and organic solvent corrosion ensures the safety and stability of chemical reactions, avoiding equipment leakage caused by refractory failure.
Petrochemical Furnaces: In oil refining and petrochemical cracking furnaces, the material`s high-temperature resistance and wear resistance can withstand the scouring of high-temperature oil and gas, extending the service life of furnace tubes and reducing maintenance costs.
Waste Incineration Furnaces: For hazardous waste and municipal solid waste incineration furnaces, corundum ramming mix`s resistance to high-temperature corrosion and ash erosion effectively prevents furnace body damage, ensuring the continuous operation of incineration equipment and meeting environmental protection emission standards.
4. Other Emerging Applications: Expanding to New High-Temperature Fields
With the development of high-temperature industrial technology, corundum ramming mix is also expanding into emerging fields such as new energy, aerospace, and thermal power.
New Energy Industry: In solar thermal power generation systems, it is used for lining high-temperature heat storage tanks and heat exchangers, leveraging its excellent thermal stability and heat storage performance to improve energy conversion efficiency.
Aerospace Industry: For rocket engine test stands and high-temperature component processing equipment, the material`s ultra-high temperature resistance (up to 2000℃ in short-term) and mechanical strength meet the extreme environmental requirements of aerospace manufacturing.
Thermal Power Plants: In coal-fired and gas-fired power plant boilers, corundum ramming mix is applied to the combustion chamber and flue linings, reducing boiler wear and corrosion, and improving the efficiency and safety of power generation equipment.
