Product Introduction
The zirconium corundum ramming mass is prepared by fused zirconium corundum particles and a small amount of additives. This product has the characteristics of convenient use, hardening at room temperature, high strength at high temperature, low thermal expansion rate, and strong resistance to glass liquid corrosion.
Features
1.High temperature resistance.
2.High pressure resistance.
3.Small thermal expansion and thermal contraction.
4.Strong thermal shock resistance.
Application
Mainly used for lining the bottom of glass kiln, filling of silica brick masonry, transition between high-alumina material and siliceous material, lining of induction furnace and fluid tank.
