🌟 Kerui Mullite Insulation Brick Production – Advanced Solutions for High-Temperature Efficiency! 🌟
At Kerui Refractory, we are proud to manufacture a full range of Mullite Insulation Bricks—including JM23, JM26, JM28, and JM30—designed to meet the rigorous demands of steel, ceramics, petrochemical, and power generation industries. Our state-of-the-art production process ensures every brick delivers outstanding performance, energy savings, and long-term durability.
Our Product Grades:
JM23 (KR-23): For applications up to 1260–1300°C, with low thermal conductivity and excellent insulation for general industrial furnaces.
JM26 (KR-26): Withstands up to 1400°C, ideal for higher temperature zones in kilns and furnaces.
JM28 (KR-28): Suitable for service up to 1500°C, perfect for glass and ceramic kilns.
JM30 (KR-30): Handles extreme environments up to 1600°C, recommended for the most demanding high-temperature applications.
Why Choose Kerui Mullite Insulation Bricks?
High Purity & Low Impurities:
Made from premium raw materials, our bricks contain 38–73% Al₂O₃ and minimal Fe₂O₃ (as low as 0.55%), resulting in stable, reliable performance even in the harshest environments.
Superior Insulation & Energy Efficiency:
With bulk densities from 0.6–1.2g/cm³ and thermal conductivity as low as 0.17 W/(m·K), Kerui bricks help maintain furnace temperatures and minimize heat loss, boosting your operational efficiency.
Excellent High-Temperature Resistance:
Classification temperatures range from 1250°C (JM23) up to 1600°C (JM30), with refractoriness up to 1790°C. These bricks are ideal for continuous use in hot blast stoves, glass furnaces, rotary kilns, and more.
Outstanding Mechanical Strength:
Cold crushing strength from 3.0–4.5MPa ensures the bricks withstand mechanical stress during installation and operation, while their low creep and high thermal shock resistance guarantee a long service life.
Strong Chemical & Erosion Resistance:
Kerui mullite insulation bricks are highly resistant to acid and alkali attack, making them suitable for corrosive environments in steel, glass, and petrochemical industries.
Lightweight & Easy to Install:
Their low density and excellent workability make handling, cutting, and installation fast and convenient, reducing labor costs and downtime.
Typical Applications:
Steel Industry: Hot blast stoves, blast furnaces, annealing furnaces, aluminum reduction cells.
Building Materials: Glass melting furnaces, heat storage chambers, cement rotary kilns, ceramic sintering kilns.
Petrochemical: Fractionation furnaces, ethylene pyrolysis, combustion pits, and reactors.
Power Generation: Boilers, incinerators, and high-efficiency furnace linings.
Kerui’s Commitment to Quality:
Strict Quality Control: Every batch is tested for density, strength, thermal conductivity, and chemical composition to ensure consistent, reliable performance.
Global Reach: Exported to 50+ countries and trusted by over 1000 partners worldwide.
Fast Delivery: Standard sizes (23011465mm) and custom shapes available, with delivery in 15–30 working days.
