Product characteristics of thermal storage alumina balls
Thermal storage alumina balls
The Thermal storage alumina balls is made of industrial alumina and refractory kaolin as the main raw materials through scientific formula, forming and high-temperature calcination.
Thermal storage alumina ballss are divided into ordinary Thermal storage alumina ballss and high-alumina Thermal storage alumina ballss. Ordinary Thermal storage alumina ballss are suitable for converters and converters in the sulfuric acid and fertilizer industries. High-alumina Thermal storage alumina ballss are suitable for hot blast stoves and heating converters in urea, steel and other industries.

Product characteristics of Thermal storage alumina balls
1. High mechanical strength;
2. Long service life;
3. Good high temperature resistance, the highest heat resistance temperature can reach 1900 ℃;
Thermal storage alumina ballss are suitable for high and low temperature shift furnaces, reforming furnaces, hydroconverters, desulfurization tanks and methanation furnaces in chemical fertilizer plants. They can disperse gas and liquid, and support, cover and protect catalysts. It can also be used in hot blast stoves and heating transformation equipment in the steel industry.
