PRODUCT DESCRIPTION

High Density Low Porosity Silica Brick

High density low porosity silica bricks are designed to meet the rigorous demands, such as high thermal conductivity, high strength, and long service life of modern large-scale, high-output coke ovens and ironmaking hot blast stoves. It’s a high-end material with cross-industry applications.. Engineered with high-purity quartz and optimized particle grading, these blocks offer unmatched density, superior mechanical strength, and exceptional thermal stability for modern high-temperature kilns and furnaces.

Advantages

l  Excellent Corrosion Resistance: Low porosity reduces slag and chemical gas penetration channels, improving acidic slag resistance and extending lining life.

l  Absolute Structural Integrity: Near-zero residual quartz keeps permanent linear change within 0–0.2% at 1500°C, completely preventing internal lining cracks or brick dropping.

l  High Refractoriness Under Load: Extreme crushing strength prevents high-load creep deformation, while the dense structure creates an airtight seal that eliminates fuel gas leaks and lowers furnace energy loss.

Applications

Coke Ovens

• Application: Combustion chamber and carbonization chamber lining walls.

• Value: High thermal conductivity shortens coking time, maximizing plant capacity while extending the total oven service life.

Glass Melting Furnaces

• Application: High-temperature superstructures, breast walls, ports, and regenerators.

• Value: Low-calcium composition stops rapid alkali-vapor corrosion in modern Oxy-Fuel combustion zones,lowering total energy consumption via low gas permeability.

Hot Blast Stoves

• Application: High-temperature linings and upper checker brick zones.

• Value: Endures continuous 1300°C hot air friction without creep deformation, ensuring consistent output of high-temperature blast air to boost blast furnace efficiency.

Specialty Kilns

• Application: Carbon baking furnaces and industrial ceramic kilns.

• Value: Serves as the definitive replacement for standard silica bricks in zones requiring high resistance to acidic corrosion and long-term volume stability.
