Product Introduction
Gunning material is an amorphous refractory material that is gunned by a jet machine. It consists of refractory aggregates and powders with a certain particle size, binders and admixtures.
According to the material, it can be divided into alkaline, aluminum silicate, zirconium-containing and silicon carbide-containing materials.
According to the composition of the gunning material, it is divided into: high aluminum, high silicon, magnesia, magnesium chromium, silicon carbide, etc. The choice of gunning material type and classification mainly depends on the specific application scenario, the highest temperature that can be reached in the kiln, the temperature fluctuation range, the slag properties, and the material of the furnace lining itself.
