Product Description
Aluminum Refractory Balls for Regenerative Pit Furnaces
Refractory ball are made from Alpha Alumina and refractory kaolin and produced by scientific formula, shaping and firing at high-temp.
Refractory ball has a lot of advantages, such as:
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 to 1900ºC
Technical Specification
Application
1) Specially used as support and covering packing for catalyst in the High-Low Temperature Shift Furnace, Converter, Hydrogenation Shift Furnace, Desulfurization Furnace, etc
2) Used as packing in hot blast heater and heat transformer in steel industries
