Product Introduction
The refractory ball is made primarily from industrial alumina and refractory kaolin, processed through scientific formulation, shaping, and high-temperature calcination. It features 1. High mechanical strength and long service life; 2. Good chemical stability, no chemical reaction with materials; 3. Excellent high-temperature resistance, withstanding temperatures up to 1900 degrees Celsius. It is especially suitable for fertilizer plant high and low temperature shift furnaces, conversion furnaces, hydroconversion reactors, desulfurization tanks, and methanation furnaces, serving to disperse gas-liquid phases, support, cover, and protect catalysts. It can also be used in hot blast furnaces and heating conversion equipment in the steel industry.
