Product Details
Andalusite Firebricks for furnace linings
Description
Andalusite bricks are refractory bricks made of natural Andalusite with excellent resistance to high temperatures, thermal shock and low thermal expansion.Andalusite brick is typically used in industrial applications at temperatures above 1300°C and is often used as a refractory for furnace linings. Andalusite is a natural mineral consisting of aluminum silicate with excellent resistance to high temperatures, thermal shock and low thermal expansion. Rhodochrosite is a natural mineral composed of aluminum silicate with excellent resistance to high temperatures and thermal shock.
Features
High temperature resistance
Andalusite brick has an excellent resistance to temperatures up to 1700°C, making it ideal for use in high-temperature industrial applications.
Low Thermal Expansion
Andalusite Firebricks have a low coefficient of thermal expansion, so they are less likely to crack or break during sudden temperature changes.
High Thermal Shock Resistance
Andalusite Firebricks have excellent thermal shock resistance; they can withstand sudden temperature changes without cracking or breaking.
Chemical Resistance
Andalusite Refractory Bricks can withstand a wide range of chemicals, including acids, alkalis and other corrosive substances found in many industrial processes.
GOOD MECHANICAL STRENGTH
Andalusite Refractory Bricks have good mechanical strength; they can withstand the weight of other materials and equipment without cracking or breaking.
Excellent insulating properties
These bricks have excellent insulating properties, which can help reduce heat loss and improve energy efficiency in industrial processes.
For any industrial application where high temperature resistance and durability are required, Rhodochrosite bricks are a quality and reliable choice. Its excellent performance and range of features make it an important part of many industrial processes.
