Features
1.They are small in size and easy to change and operation.
2.They have the advantages of good flexibility,high intensity,high temperature and air plume impingement resistance,high refractoriness,big volume concentration,high heat storage capality,anti-clinkering property,and anti-oxidation and erosion resistance.
3.The good thermal conductivity,small thermal resistance,good heat shock stability and long life.
Applications
Ceramic regenerative balls are widely used in the regenetative heating furnace,hot blast stoves,heat treatment furnaces,depolymerizing furnaces,roasters,melting furnaces,soaking pit furnaces and oil and gas boiler of smelt steel iron,machinery,building materials,petrochemicals,non-ferrous metal metallurgy etc industries.
