The impurity content of andalusite brick is low, and the high temperature strength decreases very little. It has the characteristics of rapid cooling and rapid heating resistance, high mechanical strength, strong thermal shock resistance, strong slag resistance, high refractoriness under load, high chemical stability and strong chemical corrosion resistance.

The micro-expansion of andalusite fire bricks changes the use of materials and the extension of their service life. Andalusite refractory brick are widely used in kiln and boiler of various industrial fields such as metallurgy, building materials, fine ceramics, electric power, chemical industry, etc. Andalusite refractory brick is applied on the top of some metallurgical furnaces, and the effect is better than that of silica brick.

Andalusite Bricks Advantages
The refractory andalusite brick has a low temperature, a low conversion temperature, low thermal expansion during the conversion process, and coarse crystals, andalusite rafractory bricks can be used for the aggregates, all of which can make the andalusite can be directly used for the production of fired or unburned bricks without calcination, and saves a lot of energy.

The andalusite refractory brick has a series of advantages, andalusite bricks creep resistance is strong. The creep is a measure of the long-term resistance of the refractory brick to the high temperature load, and the melt impurities which prematurely soften the andalusite refractory bricks have a great influence on the creep.

The andalusite refractory bricks have high temperature strength is high and decreases with increasing temperature.

The high temperature strength is related to the amount of liquid phase formed inside the refractory brick at a high temperature.

Andalusite brick has high temperature and volume stability, and other AL2O3-Sio2 series refractory bricks with better thermal shock stability than Al2o3 content, strong chemical resistance
