1,Description
The Mullite regenerative ball, mainly composed of mullite phase, is used as regenerative filler in blast furnace gas heating furnace. By double preheating of gas and air, the combustion temperature can quickly meet the requirements of billet heating. The product has high heat capacity,excellent suddenly-changing temperature resistance, high hardness and good wear resistance.
