Supplier's note

  1. Technical Breakthroughs:

    • Material Blend: Diatomite-MgO-silica composition reduces weight by 20% compared to traditional firebricks while maintaining structural integrity.
    • Refractoriness Range: The Base Model’s 1580–1770°C tolerance aligns with 80% of industrial furnace standards, while the Pro Model’s 2000°C rating exceeds API RP 530/531 benchmarks for extreme environments.
    • Precision Cutting: Customizable edges enable seamless integration into legacy systems, minimizing gaps and heat loss.

  2. Optimal Version Selection:

    • Base Model: Suitable for standard kilns or boilers where cost-efficiency is prioritized.
    • Advanced Model: Ideal for cement rotary kilns or glass melting tanks needing 15–20% higher thermal resistance than baseline.
    • Pro Model: Required for steelmaking ladles or petrochemical cracking furnaces where temperatures exceed 1800°C. With its 20% lower thermal conductivity than traditional bricks, the Pro Model reduces energy consumption by up to 12% in high-demand scenarios.
