The use of alumina ceramic heat storage balls is very extensive, and they have become an indispensable product in the chemical industry. They have significant characteristics such as low shrinkage rate during heavy burning, high softening temperature under high temperature load, corrosion resistance, high strength, large heat storage and release, good thermal shock stability, good thermal conductivity, and small coefficient of thermal expansion. They are excellent refractory materials.

Fireballs are widely used in the precision and deep processing of thick and hard materials in various types of ceramics, glazes, glass, chemical plants, etc. due to their excellent characteristics such as high strength, high hardness, high wear resistance, high specific gravity, small size, high temperature resistance, corrosion resistance, and no pollution.

Regenerative balls are suitable for use in combustion systems of gas and non gas fuel industrial furnaces, especially for virtual heating furnaces in the steel industry, regenerative ladle roasters, air separation equipment regenerators in the air separation industry, and regenerative melting furnaces in the non-ferrous metal industry. They can also be used as thermal storage carriers in large forging plant regenerative trolley furnaces, regenerative electric boilers, regenerative incinerators, and other industries. Regenerative balls are divided into solid balls and concave convex perforated balls.

Under the same raw materials, formula, and firing temperature, the finer the powder after grinding, the higher the specific gravity and wear resistance. The specific gravity of high alumina balls is mainly affected by the powder and firing process. Factors such as undercooking, coarse powder, and the addition of impurities can lead to insufficient specific gravity of the ball stones. Low specific gravity spherulites are not wear-resistant and prone to cracking, but high specific gravity does not necessarily mean that spherulites are wear-resistant, as excessively sintered spherulites can also achieve higher specific gravity.
