Corundum-mullite Refractory Regenerative Ball
Corundum-mullite Refractory Regenerative Ball is featured with high strength, high chemical stability and thermal stability. It is resistant to high temperature, high pressure, corrosion of acid, alkali and various organic solvent, applied to petroleum industry, chemical industry, fertilizer industry, natural gas industry and enviroment protection and capable of supporting catalysts, covering materials and buffering impact of liquid and gas to catalysts in a reactor to protect the catalysts and improve the distribution of liquid and gas in the reactor.
Advantages
1.High strength, long use period
2.Chemical stability, it won't react with our materials
3.Good performance of resistance high temperature, resistance high temperature up to1900 Centigrade.
Application
Specially used in hot blast stove, the high-low temperature shift furnace, converter, hydrogenation shift furnace, desulfurization furnace, etc
Used in the hot wind furnace and heat up shift appliance in steel plant.
