Refractory bricks are high-temperature building materials used for lining high-temperature furnaces, reactors, and other equipment. They are widely used in the metallurgical, ceramic, glass, chemical, and other industries. Refractory bricks are mainly made from refractory materials such as aluminum silicates and carbon materials.

Refractory bricks made from different raw materials have different properties and uses. Aluminum silicate bricks are suitable for high-temperature applications above 1200 degree , while magnesia bricks are suitable for high-temperature applications below 1200 degree .
Refractory bricks can also be divided into different shapes according to their shapes. The most common shapes are standard square bricks and standard rectangular bricks. In addition, there are also special shapes such as crucibles, segmented bricks, and half-moon bricks.
Refractory bricks are also divided into different grades according to their properties and uses. The most commonly used grades are standard refractory bricks and high-temperature refractory bricks. Standard refractory bricks are suitable for lining kiln walls and floors at temperatures below 1200 degree . High-temperature refractory bricks are suitable for lining kiln walls and floors at temperatures above 1200 degree .
Refractory bricks are mainly used for lining kiln walls and floors in the metallurgical, ceramic, glass, chemical, and other industries. They play an important role in ensuring the safe and stable operation of high-temperature equipment.
