Characteristics of Kerui 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 1700℃. 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 (hydrofluoric acid). 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.
