Lightweight Insulating Fire Clay Brick Heat Resistant Refractory Bricks for Chimney Furnace Kiln Wall Lining

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Temperature Resistance: Engineered from clay and alumina, these bricks withstand temperatures between 1580°C and 1770°C, making them ideal for furnaces, kilns, and industrial ovens.
  • Versatile Construction: Available in brick and block shapes with bending processing capabilities, enabling customized installations for chimneys, fireplaces, and structural applications.

Key features

  • 1. Material Technology

    • With a clay and alumina composition infused with 40% chromium oxide (Cro), these bricks achieve superior heat resistance and durability, outperforming traditional clay bricks lacking such advanced material blends*.

  • 2. Performance Parameters

    • With a refractoriness of 1580–1770°C, these bricks can withstand extreme temperatures, outperforming standard refractory bricks rated below 1580°C*.

  • 3. Certification Standards

    • Certified to RoHS, CE, and EPR Germany Packing standards, these bricks meet stringent safety and environmental regulations, unlike uncertified alternatives*.

  • 4. Scenario Solutions

    • Designed for industrial furnaces and kilns, these bricks ensure uninterrupted operation in high-temperature environments where conventional bricks may degrade prematurely*.

  • 5. Interactive Design (Processing)

    • With bending capabilities, these bricks can be customized to fit complex structural designs, offering greater flexibility than rigid refractory materials*.

Supplier's note

  1. Technical Breakthroughs:

    • Pro Model’s refractoriness exceeds 1700°C, enabling safe operation in blast furnaces and high-temperature kilns.
    • Reduced thermal conductivity in Advanced/Pro models cuts heat loss by up to 33%, improving energy efficiency.
    • Enhanced Cro Content in the Pro model boosts chemical resistance for corrosive industrial environments.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard industrial applications like low-to-moderate heat chimneys.
    • Advanced Model: Perfect for moderate-heat environments requiring lighter weight (e.g., kiln walls).
    • Pro Model: Best for extreme high-temperature and corrosive scenarios (e.g., metallurgical furnaces).

With the Pro model’s 1770°C refractoriness, you can safely handle intense furnace operations. Its 45% Cro content ensures longevity in acidic or alkaline environments. The Advanced model’s 20% lighter density reduces installation labor costs while maintaining thermal performance. Choose based on your operational temperature and chemical exposure needs.
