Performance characteristics and uses
Refractory ball is industrial alumina refractory clay as the main raw material, made by scientific formula forming and high-temperature calcination, it has:
1, high mechanical strength, long life cycle;
2, good chemical stability, do not react chemically with the material;
3, high temperature performance, and the highest heat resistance temperature can reach 1900 degrees Celsius. Particularly applicable to the fertilizer plant high and low temperature transformation furnace reformer, hydroconversion, desulfurization groove and methanation furnace, since the dispersed gas-liquid and support, covering and protection of the role of catalyst. Can also be used in the stove and heating of the steel industry in the conversion equipment.
