99% Alumina Ceramic Ball for Thermal Storage
It is widely used in heating furnace, aluminum melting furnace, forging furnace and other industrial furnaces in iron and steel, metallurgy industry. It is especially suitable for the regenerator of air separation equipment and blast furnace gas heating furnace of iron and steel works as heat storage filler. By double preheating of gas and air, the combustion temperature can quickly meet the requirements of billet heating for steel rolling.
Main specifications of high aluminum heat storage ball: 3mm, 6mm, 8mm, 10mm, 13mm, 16mm, 19mm, 25mm Advantages of Bomai products: high strength, wear resistance, cold and hot resistance, long service life, higher cost performance with imported ceramic balls
Our innovative Ceramic balls for ball mill, High Purity Ultrafine Alumina Lining Sheet, Zirconia Ceramic Lining Brick can not only meet the current needs of many manufacturing and research customers, but also meet their future needs. While constantly improving ourselves, we will adopt a sincere service attitude and a high degree of responsibility. Our modern management model, unity and progressive spirit, and tireless dedication are a powerful guarantee for the development of our company.
Product Introduction
The thermal storage ceramic ball is a ceramic product made of α-alumina as the basic raw material, which is rolled or pressed, and sintered at high temperature.High-alumina heat storage balls are many small balls that divide the airflow into small streams. When the airflow flows through the heat conductor, a strong turbulent flow is formed, which effectively breaks through the boundary layer on the surface of the heat conductor. Good thermal conductivity, so it can meet the requirements of frequent and rapid reversing of heat conduction burners.
High-alumina heat storage balls are also called spherical heat storage bodies. Spherical heat storage bodies have the advantages of good thermal shock stability, large heat storage, high strength, easy cleaning, and reusability.
Advantage
1. The heat conductor can be reversed 20~30 times/h. After the high-temperature air flows through the heat conductor bed, the flue gas can be reduced to about 130°C and discharged.
2. High-temperature natural gas and air can be preheated to only about 100°C lower than the flue gas temperature in the same path through the heat conductor, and the temperature efficiency is as high as more than 90%.
3. Due to the very small size of the heat conductor and the strong flow capacity of the high-alumina heat storage ball bed, even if the resistance increases after dust accumulation, the heat exchange index will not be affected.
4. Thermal storage ceramic ball have the characteristics of strong oxidation resistance and slag resistance.
5. The replacement and cleaning of high alumina heat storage balls are very convenient and can be used repeatedly.

Application
The thermal storage ceramic ball is suitable for the selection of the heat storage ball combustion system of gas and non-gas fuel industrial furnaces, especially for the virtual heat heating furnace in the iron and steel industry, the heat storage ladle baker, the air separation equipment heat accumulator in the air separation industry, and the nonferrous metals. The regenerative smelting furnace in the metal industry can also be used as a regenerative carrier in large-scale forging plants such as regenerative trolley furnaces, regenerative electric boilers, and regenerative incinerators.
Alumina Ceramic Balls We are more concerned about the quality of, so the quality of those elements should be explained here.
1. The compressive strength and strength of ceramic balls are very important technical parameters. The strength can be tested by equipment. When foreign customers inspect, the ceramic balls fall freely from high altitude, directly fall on the steel plate of specified thickness at the specified height, and see how many pieces are broken within 10.
2. The aluminum content of ceramic balls and the main components of inert alumina ceramic balls are aluminum oxide and silicon dioxide. According to the national standard, the proportion of the two is more than 90%. The aluminum content is a very important test item, because the higher the aluminum, the higher the strength and other indicators are correspondingly improved.
3. Luster of ceramic ball. If the raw material of ceramic ball exceeds the standard of iron after high temperature sintering, there will be stains on the surface of ceramic ball, which will directly affect the first impression of customers.
