High Quality Silica Brick For Glass Furnace

High Quality Silica Brick For Glass Furnace

Product Parameters

Silica Bricks
Silica bricks are mainly made from chamotte, being high pressure pressed and sintered in high temperature. Main minerals compositions are mullite phases. These products are widely used in all parts of furnace lining for middle and small capacity blast furnaces because of their excellent physical and chemical properties in high temperature. It also can be used in lining for other kinds of furnace with good resistance to acidic slag erosion.
Product Features
High Refractoriness: Up to 1690℃ – 1730℃, stable at high temperatures, providing reliable fire – resistant protection for glass kilns.
High Load – Bearing Softening Temperature: Generally 1620℃ – 1670℃, not easily deformed under high – temperature pressure, ensuring the long – term structural stability of glass kilns.
Strong Acid – Erosion Resistance: Effectively resists acidic gases and furnace slags in glass kilns, extending the service life.
Moderate Thermal Shock Stability: Relatively weak, but can meet the needs of parts with stable temperature changes through proper design.
Good High – Temperature Volume Stability: Small volume change at high temperatures, ensuring the integrity and tightness of glass – kiln masonry and improving thermal efficiency.
Main Application Areas
The regenerators of glass kilns: With high load – bearing softening temperature and acid – erosion resistance, it works stably in high – temperature and acidic – gas environments, improving heat – recovery efficiency and reducing energy consumption.
The small furnaces of glass kilns: High refractoriness and high – temperature volume stability enable it to withstand high – temperature flame scouring and temperature fluctuations, ensuring normal operation and stable heat supply.
The flue ducts of glass kilns: Acid – erosion resistance and high – temperature stability enable it to resist acidic – gas erosion in waste gas, ensuring normal use of flue ducts and smooth waste – gas discharge.
