Refractory Balls Hot Air Stove/Heating Heat Exchange Equipment Heat Storage Balls
The main materials of refractory ball are industrial alumina and
fire-proof kaolin, it is made by scientific formula, molding and
high temperature calcination. Its maximum refractoriness can reach
1900℃. It is of high mechanical strength, long service life, good
chemical stability, high temperature resistance, etc
