Zirconium fire-resistant products
|
Zirconium brick, the aluminium-zirconium-silicate brick, subjected to repeated sintering, and 333-production are characterized by high characteristics of fire resistance, good thermostability, and also stability to corrosion and erosion of glass mass. This kind of fire-resistant production is applied in high-temperature elements of glass-manufacturing furnaces, steel-pouring ladle and so forth 333-production is made of a high-quality material and used in devices of a feeder.
