Xintai Glass Kilns Fire Clay Bricks are specially designed for glass melting furnaces and regenerators where excellent thermal stability, resistance to creep deformation, and long service life are essential. Manufactured from high-quality bauxite clinker, andalusite, and fused mullite through advanced grading and high-temperature firing processes, these bricks provide outstanding performance under continuous high-temperature conditions.
Compared with ordinary fire clay bricks, Glass Kilns Fire Clay Bricks offer higher refractoriness under load, superior resistance to thermal shock, and enhanced resistance to alkali vapor and slag attack. They are widely used in regenerators, partition walls, checker chambers, and other critical areas of glass furnaces requiring stable operation and dimensional accuracy.

Product Features of Glass Kiln Fire Clay Bricks
- Excellent Resistance to High-Temperature Creep: With a creep rate below 0.4%, the bricks maintain dimensional stability during prolonged service in glass furnace regenerators and checker chambers.
- High Refractoriness Under Load: The load softening temperature exceeds 1450°C, ensuring reliable performance under continuous thermal and mechanical stress.
- Dense Structure and Low Porosity: Apparent porosity below 17% effectively minimizes penetration of molten materials and alkali vapors, improving corrosion resistance.
- Superior Thermal Shock Resistance: Optimized particle distribution and selected raw materials provide excellent resistance to repeated heating and cooling cycles.
- High Mechanical Strength: Cold crushing strength above 40 MPa enables the bricks to withstand heavy loads and maintain structural integrity throughout furnace campaigns.
- Long Service Life: Outstanding high-temperature properties help reduce shutdown frequency, lower maintenance costs, and extend furnace operating cycles.
Applications
- Glass Melting Furnaces: Widely used in critical sections requiring excellent thermal stability and long-term resistance to deformation.
- Regenerators: Suitable for checker chambers, partition walls, and regenerator walls where continuous heat exchange occurs.
- Glass Furnace Checker Chambers: Provide excellent load-bearing capability and resistance to thermal cycling.
- Side Walls and Partition Walls: Maintain structural stability under high-temperature and corrosive atmospheres.
- Other Industrial Furnaces: Hot blast stoves, Coke ovens, Ceramic kilns, Metallurgical furnaces, Petrochemical furnaces, Lime and cement kilns
