High quality zircon brick for glass furnace
Zircon refractory brick is made of natural zircon sand (ZrSiO2) as raw material. The zircon silicate brick is fired in 1600℃ furnace with the zircon content more than 65%. The Zircon bricks have compact crystal structure, high density and high mechanical strength. Since it has good thermal shock stability, low re-fire shrinkage and high temperature creep, and has extremely high chemical stability and resistance to alkaline media, it is widely used in glass industry.
As a professional zirconia bricks manufacturer, we have exported different zircon refractory bricks to more than 30 countries. Please kindly read the following more information and makeIn
Scope of application:
lZircon Silicate bricksis widely used inLining of alkali-free or low-alkali glass, sodium-calcium glass, boron-silicate glass, ceramic glass,lead glass, and other technical glass melting furnace.
Advantage:
lGood slag resistance
lLow thermal expansion rate
lThermal conductivity decreases with increasing temperature
lHigh load softening temperature
lHigh abrasion resistance
lGood thermal shock resistance
lLong using life
