Shandong Luming New Materials Technology Co., Ltd. is one of the leading manufacturers and suppliers of fire clay block in China. We have world-leading production equipment and strong manufacturing capabilities. Please feel free to buy premium fire clay block at competitive price from our factory.
Fire clay block is large-sized refractory products made primarily from fire clay (e.g., kaolin or other aluminosilicate minerals), typically used for linings, flooring, or other surfaces requiring high-temperature resistance and erosion resistance in industrial furnaces or kilns. Compared to traditional fire clay bricks or standard fire clay tiles, fire clay large panels feature larger dimensions, higher construction efficiency, and enhanced overall performance.

Performance Advantages of Jumbo Fireclay Brick
High Refractoriness: Typically withstands temperatures of 1600°C–1700°C, suitable for medium-to-high-temperature industrial environments.
Excellent High-Temperature Strength and Load Softening Temperature: Maintains high strength and structural stability at elevated temperatures, resisting deformation.
Good Thermal Shock Resistance: Can withstand drastic temperature changes without cracking or spalling.
Strong Resistance to Erosion and Abrasion: Their dense structure and excellent chemical stability allow them to resist corrosion from molten slag, molten metals, and abrasive materials.
Good Dimensional Stability: Exhibits minimal volume changes at high temperatures, resisting shrinkage or expansion.
Low Porosity: Apparent porosity ranges from 15%–25%, falling between low-porosity clay bricks (10%–17%) and ordinary clay bricks (20%–30%). High-performance panels can achieve lower porosity through process optimization.
Good Thermal Conductivity: Moderate thermal conductivity (approximately 1.0–1.5 W/m·K), balancing insulation and heat transfer needs.
Structural Integrity: Large dimensions reduce the number of joints, decrease thermal stress concentration, and improve overall furnace strength.
Construction Efficiency: Large dimensions (e.g., 500x500 mm, 1000x500 mm, or larger), reducing joints and improving construction efficiency.And reduces masonry workload, shortens construction period, and lowers labor costs.
Sealing Performance: Fewer joints improve furnace airtightness and reduce heat loss.
Application Areas
Fire clay large panels, with their large size, high construction efficiency, and high-temperature resistance, are widely used in the following areas:
1.Iron and Steel Industry:
1).Hot Blast Stove Linings: Especially the lower section and checkerwork of hot blast stove regenerators, where large slabs provide better airtightness and strength.
2).Blast Furnace Bottom and Hearth: Used to construct critical sections of the furnace bottom and hearth, minimizing joints and enhancing penetration resistance.
3).Ladle Linings: Used in specific sections of some large ladles to improve overall lifespan.
4).Heating furnaces :Insulation or working layers
5).Non-critical linings in ladles or tundishes.
2.Non-Ferrous Metals Industry:
1).Aluminum Electrolytic Cell Side Walls and Bottom Linings: Provides excellent resistance to molten aluminum corrosion.
2).Copper, Lead, Zinc, and other Smelting Furnaces: Used for linings in molten pools and critical erosion-prone areas.
3).Reverberatory furnaces, converter hearths, and sidewall masonry.
3.Glass Industry:
1).Glass Melting Furnace Bottom and Walls: Withstands prolonged contact with molten glass at high temperatures; large slabs reduce permeation and extend furnace life.
2).Regenerator Checkerwork: Used in high-temperature regenerators to improve heat storage efficiency and stability.
4.Cement Industry:
1).Rotary Kiln Burning Zone Linings: Used in the high-temperature zone of cement rotary kilns, resisting high temperatures, abrasion, and chemical attack.
2).Waste Incinerators: In critical parts of incinerators, resisting high-temperature corrosion and abrasion.
5.Petrochemical Industry: Catalytic cracking units, heating furnaces, and other high-temperature equipment.
6.Ceramic kilns and other Industrial Kilns and Furnaces: Any industrial kiln or furnace requiring large-area, high-strength, and long-life refractory linings may consider using large fireclay slabs.
