Supplier's note

  1. Technical Breakthroughs:

    • Al₂O₃ Content: The ≥75% alumina ensures structural stability at 1770°C, outperforming standard firebricks.
    • Ultra-Low MgO: ≤0.1% MgO minimizes chemical erosion, extending lifespan in acidic environments.
    • CE Compliance: Meets EU safety standards for industrial kilns and incinerators.

  2. Version Selection Guide:

    • Base Model: Ideal for standard kilns (≤1770°C) where cost-efficiency is prioritized.
    • Advanced Model: Choose for chemical plants needing corrosion resistance (e.g., 40% Cro content) and moderate thermal demands.
    • Pro Model: Required for extreme applications like steel smelting furnaces, where 2050°C resistance and high load-bearing are critical.

*Pro Model’s refractoriness exceeds industry benchmarks by 20%, enabling use in ultra-high-temperature foundries.
