Product Details
Amorphous refractory pounding material is divided into two types: AZS and pure zirconium, which can be used for bottoming and hot patching of silicate kilns. It has the characteristics of high density, good chemical stability, thermal stability and good plasticity.
AZS ramming mass is indefinite zirconium refractory material, divided into AZS-50H, AZS-06H and AZS-04H. Through the use of many glass furnaces, the product has good construction performance and strong resistance to glass erosion. At the same time, the service life of the furnace is also obviously improved. Therefore, it is widely used in glass kiln, glass fiber kiln and rock wool kiln in the bottom and wall of the pool insulation, thermal patching.
