    Andalusite Bricks for Hot Blast Stove

    Andalusite Brick for Hot Blast Stove: Andalusite is heated to 1300 ℃ and becomes mullite. It is a high-grade refractory, which is the same as kyanite.
    In the process of heating andalusite into mullite, a good mullite network can be formed, and the volume expansion is about 4%. This is an irreversible crystal transformation. Once transformed, it has higher fire resistance. The fire resistance can reach above 1800 ℃, and it has high resistance to sudden cooling and heat, high mechanical strength, strong thermal shock resistance, strong slag resistance, high load conversion point, high chemical stability (even insoluble in hydrofluoric acid) and strong chemical corrosion resistance.

    Andalusite bricks are a type of refractory product that have been gaining attention since the 1970s for their high performance in various industrial applications. These bricks are primarily made of al2o3 (alumina) and possess a range of properties that make them suitable for high-temperature and demanding environments. Here’s a comprehensive overview of andalusite bricks, including their production, properties, and applications:

    Andalusite Brick

    Production Process

    1. Raw Materials: The primary materials used for making andalusite bricks include mullite powder, andalusite fine powder, sillimanite fine powder, clay, and silicon micropowder.
    2. Manufacturing Process: The production involves mixing these raw materials in a sand mixer following a specific formula. After mixing, the mixture is shaped into bricks using a brick press. These bricks are then dried and fired in a kiln to produce the final andalusite refractory bricks​​.

     

    Properties of Andalusite Bricks

    1. High-Temperature Resistance: Andalusite bricks can withstand temperatures above 1800 °C. Upon heating, they convert into mullite, enhancing their fire resistance.
    2. Thermal Expansion: They exhibit low thermal expansion during the conversion process to mullite.
    3. Mechanical Strength: These bricks maintain strength under high-temperature conditions and are resistant to rapid cooling and heating.
    4. Chemical Stability: Andalusite bricks are chemically stable, resistant to chemical attack, and even insoluble in hydrofluoric acid.
    5. Thermal Shock Resistance: They have strong thermal shock resistance and high load conversion points.
    6. Low Porosity and Creep Rate: The bricks exhibit low porosity and a low rate of creep under high temperatures​​.

     

    Applications

    Andalusite bricks have a wide range of applications due to their high refractoriness under load, low porosity, and excellent thermal shock resistance. They are used in:

    • Bodies of hot stoves.
    • Torpedo cars.
    • Ladles.
    • Glass furnaces.
    • Roofs of electric furnaces.
    • Heating furnaces​​.

     

    In summary, andalusite bricks are a versatile and robust refractory solution. Their superior thermal and chemical stability, combined with high mechanical strength and resistance to thermal shock, make them ideal for use in various high-temperature industrial applications. Their ability to transform into mullite under heat contributes to their high refractoriness and durability, making them a preferred choice in metallurgy and other related industries.

  • Corundum Chrome Brick

    Corundum Chrome Brick

    Corundum Chrome Brick (KPA) is the premium version of Alumina Chrome Brick

    Corundum Chrome Brick (KPA ) made primarily of high purity chrome corundum clinker, alumina and chrome oxides under high temperature burning, KPA has better properties in refractories, RUL, MOR, high temperature creep, volume stability and resistance to slag corrosion compared with pure corundum bricks. It can be used as enhanced High Purity Corundum Brick (HPA)

    It has excellent acid resistance and high temperature resistance. Widely used in chemical industry, glass, waste incineration, non-ferrous metal smelting and other key parts of the industry.

    Corundum Chrome Brick
    Alumina Chrome Brick
    consist of combinations of the two oxides fired to develop a solid-solution bond. A wide range of products are available depending upon Cr2O3 content. These include a 90% Al2O3-10% Cr2O3 product based on high purity sintered alumina and pure chromic oxide. The solid solution developed in firing results in brick with exceptional cold strength, hot strength and load-bearing ability. In addition, the solid-solution bond between alumina and chromic oxide is inert to a wide variety of slags. Brick with higher Cr2O3 contents is also available. Based on a special fused grain high in chromic oxide, these products are selected for the most extreme cases of high temperature and corrosiveness.

  • Common High Alumina Brick.

    Common High Alumina Brick.

    The term High Alumina Brick refers to refractory brick having an alumina (AI2O3) content of 47.5% or higher. This descriptive title distinguishes them from brick made predominantly of clay or other aluminosilicates which have an alumina content below 47.5%.
    High-alumina brick are classified by their alumina content according to the following ASTM convention. The 50%, 60%, 70% and 80% alumina classes contain their respective alumina contents with an allowable range of plus or minus 2.5% from the respective nominal values. The 85% and 90% alumina classes differ in that their allowable range is plus or minus 2% from nominal.

  • Corundum Brick

    Corundum Brick

    High Purity Corundum Brick (HPA) contain tabular alumina as the base grain and may include various fine materials such as calcined alumina, clay and fine silica. As these bricks generally have low impurity levels, alumina and silica typically make up 99% of the chemical composition. Usually, the only mineral phases present are corundum and mullite. Properties such as high hot strength, creep and slag resistance benefit from this purity level.

     

    HPA made primarily of alumina under medium to high temperature burning, HPA has advantages such as high purity, strength, chemical stability and corrosion resistance. It was widely used as internal lining of petrochemical and instrument equipment such as ammonia gasifier, ethylene gasifier and carbon black reactor, in which high temperature, pressure, chemical corrosion and mechanical abrasion is encountered.
