Product overview
Fused cast AZS 41 brick is the most excellent product in fused cast AZS series, it has the best corrosion resistibility to the molten glass, the glass phase exudation temperature is extremely high, and the pollution to the molten glass is extremely low. Therefore, it is usually recommended to be used in quick wear positions of glass kilns to balance the life of kiln, such as sidewall of the furnace hot point, doghouse corner, throat, weir block, Bubble block, etc and the furnace that require very high corrosion resistibility, like the whole electric furnace.
Character
Best corrosion resistance, very high glass exudation temperature, suitable for the important position of furnace to balance the furnace life. Such as doghouse corner, throat, weir block, bubble block and the whole electric furnace.
