Types of zirconium ramming materials and their application in glass kiln

Zirconium ramming material is mainly composed of zirconium aggregates, powders, binders, and additives. It is an amorphous refractory with low plasticity and is used in glass kilns.
There are two commonly used zirconium ramming materials for glass kilns, namely zircon ramming materials and fused AZS ramming materials. Although the two zirconium ramming materials have similar resistance to glass liquid corrosion, the content of AM) in the zircon ramming materials is extremely low, and the apparent porosity of the two ramming materials is different. Through analysis and comparison , Fused AZS ramming material is more suitable for soda lime silica glass, electric vacuum glass and other alkaline glass furnace bottom ramming layer, while zircon ramming material is more suitable for borosilicate, etc. The bottom ramming layer of the weakly alkaline glass furnace.
