Refractory ball with smooth surface, corrosion resistance, wear resistance, high strength, thermal conductivity and thermal capacity, high thermal efficiency, good thermal stability and storage temperature change is not easy to fracture, etc. Refractory ball usually used in shift converter and reformer in ammonia plant. Refractory ball has a lot of advantages, such as:
High strength, long use period.
Chemical stability, it won't react with the materials.
Good performance of resistance high temperature, resistance high temperature up to 1900ºC.
