Product description of AZS Ramming Mass
Amorphous refractory materials are divided into two types. Azs and pure zirconium, which can be used for the bottom and heating of silicate furnaces. It has the characteristics of high density, good chemical stability, good thermal stability and high plasticity.
Features of AZS Ramming Mass
AZS compactor is an amorphous zirconium refractory divided into azs – 50h, azs – 06h and azs – 04h. Due to the use of several glass furnaces, the product has a good construction performance and a high resistance to glass corrosion. Meanwhile, the service life of the furnace has also been improved considerably. Therefore, it is widely used for thermal insulation and thermal repair of the bottom and tank wall of glass furnace, glass fibre furnace and rock wool furnace.
