Andalusite brick has high Al2O3 content and low impurity content, making it an ideal high-grade refractory material.
At the same time, the volume change of andalusite refractory bricks during the sintering process is stable. Andalusite refractory bricks have good low thermal conductivity, high resistance to slag corrosion and creep resistance. Refractory bricks have high thermal strength, low porosity, resistance to pressure drop and crushing, deformation resistance, thermal shock resistance, and good fire resistance. The micro-expansion of andalusite refractory bricks changes the use of materials and the extension of service life.
Andalusite refractory bricks are widely used in kilns and boilers in various industrial fields such as metallurgy, building materials, fine ceramics, electric power, and chemical industries. Andalusite refractory bricks are used in some metallurgical furnace tops, and the effect is better than silica bricks.
