2.Product Introduction
1. High mechanical strength and long service life;
2. Good chemical stability, no chemical reaction with materials;
3. Good high-temperature resistance, the highest heat resistance temperature of the refractory ceramic ball can reach 1900 degrees.
It is particularly suitable for high and low-temperature shift furnaces, reformers, hydroconverters, desulfurization tanks, and merchandizers in chemical fertilizer plants, and plays the role of dispersing gas and liquid, supporting, covering, and protecting catalysts. Refractory ceramic balls can also be used in hot blast stoves and heating conversion equipment in the iron and steel industry.
Refractory ceramic balls are divided into ordinary refractory balls and high alumina refractory balls. Common refractory balls are suitable for converters and converters in the sulfuric acid and fertilizer industries, and high alumina refractory balls are suitable for hot blast stoves, heating converters, and other equipment in urea, steel, and other industries.
