Characteristics of Andalusite Fire Bricks
Great Refractoriness
Andalusite refractory bricks have great refractoriness under high-temperature situations. After heating them, they will have better refractoriness than mullite bricks. Andalusite refractory bricks can resist up to 1700ºC. They can be used for the linings and other parts of the high-temperature equipment.
Chemical Stability
Andalusite blocks have excellent chemical stability. They will not eroded by chemical materials so that affects the production. Besides, they even have insoluble strong acids like HF. In complex industrial equipment, a stable chemical capacity is the key to extending the life cycle of equipment.
Low Creep Rate
Andalusite bricks have a low creep rate. This contributes to keeping the volume of equipment. And they will not affected by thermal shock in the high-temperature environment. In this situation, the safety hazard is avoided in the production process.
Good Mechanical Shock Resistance
Good mechanical shock resistance helps fire andalusite brick resist the shock of the equipment in the working process. The bricks will not easily peel off. Therefore, this brick can used in the industrial equipment with strong shock environment.
Applications of Andalusite Brick
Due to the excellent performance of andalusite bricks, these bricks are widely used for various industrial high-temperature equipment. You can use them in the ceramic industry, glass industry, metallurgy industry, cement industry, steel industry, and so on.
Andalusite brick can be used for the linings of hot blast stoves, glass furnaces, ceramic furnaces, cement rotaries, ladles, etc. It also can used in hot blast outlets, nozzle material, and other parts of industrial equipment.
