Chrome zircon mullite brick adopts mullite and chrome sand as raw material with adding material. This brick is mainly used for the important part of glass furnace. This kind of brick has good acid-resistance, anti-stripping, shock resistance and many other features which could solve the problems resulted from the unstableness of glass kiln refractory and extent the longevity of glass furnace.
Because the erosion of glass metal the wall of glass furnace will become thinner and the wall will cracking then the glass metal will spread out of the furnace. As a kind of repairing brick, Chrome Zircon Mullite Brick could directly close to high temperature without explosion, resist the erosion of glass metal and extent the longevity of glass furnace about 3-5 years.
Not only used for the tongue arch, crater arch, wall hook and spray nozzle arch of glass furnace chamber, but the regenerator upper checker in glass kiln or glass wool. It is also used for the arch brick of spray nozzle in electrical kiln, ceramic kiln, enamel kiln, alkali kiln, glass wool kiln, fiberglass kiln, float glass kiln, end fire furnace etc.
