High performance refractory bricks

High-Performance Refractory / Fire Bricks

Refractory bricks, also known as furnace bricks, are engineered to withstand extreme temperatures and harsh industrial conditions. These durable, heat-resistant bricks are ideal for building and repairing high-temperature furnaces, kilns, incinerators, and fireplaces.  We offer high performance, long life, thermal resistance more than 2300 deg cel.

    Types of Refractory Bricks available:

• • • Acidic type:
      • Silica Bricks: Primarily made of silica, these bricks are known for their ability to withstand high temperatures and their resistance to acidic slags.
      • Fireclay Bricks: Composed of alumina and silica, these bricks are versatile and used in a variety of high-temperature applications.
    • Basic type:
      • Magnesia Bricks: These bricks are made from magnesite and are excellent for environments where basic (alkaline) slags are present, such as steelmaking furnaces.
      • Dolomite Bricks: Similar to magnesia bricks but with added calcium carbonate, provide enhanced durability and chemical resistance.
    • Neutral type:
      • Chromite Bricks: Made from chromium and iron ore, these bricks are resistant to both acidic and basic slags.
      • Alumina Bricks: With a high alumina content, these bricks offer excellent resistance to high temperatures and wear-tear.

    Properties:

• • • • Thermal Conductivity: Refractory bricks must have low thermal conductivity to provide effective insulation and conserve energy within high-temperature environments.
      • Thermal Shock Resistance: should withstand rapid temperature changes without cracking or deteriorating
      • Mechanical Strength: High compressive strength to bear heavy loads and mechanical stress.
      • Chemical Resistance: These must resist chemical effect from slags, gases, and other materials.

     Applications:

• • • • Metallurgical Industries
      • Blast Furnaces: Refractory bricks line blast furnaces’ interior to withstand the intense heat and mechanical stress during the smelting process.
      • Steelmaking Furnaces: These bricks are used in steelmaking furnaces due to their resistance to basic slags and high temperatures.
      • Glass Manufacturing
      • Ceramics Industry: to maintain the necessary high temperatures and protect the structure from thermal damage.
      • Chemical Processing: These bricks are used to line reactors and containment vessels, due to chemical resistance and high thermal insulation.
