Andalusite refractory brick introduction
For more information, please visit andalusite powder.
Andalusite 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.
Advantages of Andalusite Brick
Refractory andalusite bricks have low temperatures, low conversion rates, and lower thermal expansion. During the conversion process, coarse crystals, andalusite refractory bricks can be used for polymerization, all of which can make andalusite can be directly used to produce fired or unburned bricks No calcination, and save a lot of energy.
Andalusite refractory bricks have a series of advantages and strong creep resistance. Creep is a measure for refractory bricks to resist high temperature load for a long time. The premature softening of andalusite refractory bricks by molten impurities has a great influence on creep.
Andalusite refractory bricks have high high temperature strength and decrease with the increase of temperature.
High temperature strength is related to the amount of liquid phase formed by refractory bricks at high temperatures.
Andalusite brick has the characteristics of high temperature resistance and good volume stability. Other Al2O3-SiO2 series refractory bricks have better thermal shock stability than Al2O3 content and strong chemical resistance.
Andalusite brick has a dense and uniform single structure, which is used to resist slag, penetration and corrosion of refractory materials in steelmaking furnace lining.
1 Low creep rate
2 High temperature resistance

Technical data for Andalusite brick
Manufacturing process of andalusite brick
The production process of andalusite refractory brick includes the following steps:
Prepare andalusite fine powder, mullite powder and sillimanite fine powder according to the formula ratio, and put them into the sand mixer for mixing.
Add clay and water accounting for 2% of the total weight of the raw material, and then add silica powder as an additive for mixing and stirring.
Press the mixed materials into bricks with consistent specifications using a brick press.
Place the bricks in a drying kiln and air dry until the moisture content is less than 0.5%.
The bricks are put into the sintering kiln for high-temperature sintering, so that the andalusite refractory bricks can reach the required performance indicators.
It should be noted that throughout the entire production process, the quality of various raw materials needs to be strictly controlled to ensure that the product meets standard requirements. At the same time, in order to enhance the performance of the product, an appropriate amount of additives can be added or sintering temperature can be controlled according to actual needs. It can be seen that the production of high-quality andalusite refractory bricks requires complex production processes and precise production control.
Application of andalusite refractory bricks in industrial kilns
Andalusite refractory brick is a kind of high-quality refractory material, which is widely used in various industrial kilns because of its high temperature fire resistance, corrosion resistance and excellent thermal stability.
In industrial kilns, andalusite refractory bricks can be used as masonry materials for the walls, tops and floors of kilns to protect the interior of kilns from high temperature and corrosive substances. In addition, andalusite refractory bricks can also be used for lining of hot metal tanks, converters and other high-temperature equipment to ensure normal operation of equipment.
In a word, andalusite refractory bricks are widely used in industrial kilns. They can give play to their excellent fire resistance performance in high temperature and harsh environment, providing important support for industrial production.
The following are the kilns that can be used:
1 Blast furnace
2 Hot air stove
3 Soaking furnace
4 Steel drums
5 Ladle, cement rotary kiln
6 Ceramic tunnel kiln and glass kiln
7 Lining nozzle, nozzle material
8 Teeming ladle lining
