Refractory Ceramic Balls are produced by using industrial alumina and fire-resistant kaolin as the main raw materials through scientific compounding, shaping and high-tempreature calcination. Fire resistance ceramic ball has high mechanical strength and long service life, and refractory ceramic balls have good chemical stability, It has excellent high tempreature resistance and the highest heat-resistant tempreature which can reach as high as 1900 °C.It is usually used in shift converter and reformer in plant.
refractory ball Characteristics and advantages
1.High mechanical strength (Monolithic spheres will not split, crack or spall in use)
2.High temperature resistance
3.Lower water absorption
4.Quite excellent chemical stability
5.Can resist corrosion of acid, alkali and other organic solvent
6.Excellent thermal shock resistance (can withstand the temperature urgent changes occurred in production process)
7.Trouble-free reactor filling due to high crush strength
8.Will not plug catalyst bed, optimizing the process efficiency by keeping the pressure drop low and catalyst activity high
9.No contaminate catalyst due to maximize resistance to attrition, extending the catalyst Activity life and reduce the operation cost
