Performance Advantages and Applications of Corundum Thermal Storage Balls- Zhejiang Shangguijuli Special Material Technology Co., Ltd.

Corundum thermal storage balls, a highly efficient and heat-resistant thermal storage material, play a crucial role in modern industries. Primarily composed of alumina (Al₂O₃), these balls are widely used in steel, chemical, and energy industries due to their unique physical and chemical properties.

Performance Advantages

High-Temperature Stability
The maximum operating temperature of corundum thermal storage balls can reach up to 1800℃, making them highly effective in high-temperature storage systems. Unlike traditional thermal storage materials, corundum does not undergo chemical decomposition or structural damage at high temperatures, ensuring long-term stability and reliability.

Excellent Thermal Conductivity
Corundum has excellent thermal conductivity, allowing thermal storage balls to quickly absorb and release heat in a short time, significantly improving the energy efficiency of systems. Especially in steel smelting and high-temperature furnaces, its high thermal conductivity helps reduce energy consumption and enhances production efficiency.

High Mechanical Strength
Due to the dense structure of corundum, the thermal storage balls exhibit outstanding compressive strength, maintaining stability under high temperatures and heavy loads. Their wear resistance and impact resistance make them suitable for long-term use with low maintenance costs.

Strong Corrosion Resistance
Corundum thermal storage balls have excellent corrosion resistance in atmospheric environments and in the presence of some acidic and alkaline gases. This allows them to maintain a long service life in harsh industrial environments, reducing material replacement frequency and lowering maintenance costs.

Applications

Steel Industry
Effective heat management is critical in steel smelting processes. Corundum thermal storage balls are commonly used in blast furnace hot stoves and converters to assist in heat storage and heat exchange, improving energy efficiency and extending the life of equipment.

Chemical Industry
In the chemical industry, some high-temperature reactors and furnaces require a consistently stable high-temperature environment. Corundum thermal storage balls, due to their heat resistance and excellent thermal conductivity, are widely used in processes such as high-temperature cracking and catalytic reactions.

New Energy Sector
With the rapid development of renewable energy sources like solar power, corundum thermal storage balls play an important role in energy storage systems. They can store solar heat during the day and release it at night, ensuring stable energy supply.
