Product Description

Manufacturer SK Series Dense Bricks Customizable Various Grades Specifications Refractory Brick
Fire clay brick and high alumina brick are both belonging to Al2O3-SiO2 bricks. They can be divided into standard shapes and unique shapes. Standard shapes have dimensions conformed by most refractory manufacturers and are generally applicable to kilns or furnaces of the same types. Standard shapes are usually bricks that have a standard dimension of 230 × 114 × 65 mm. There are ranges of standard shapes of different sizes manufactured to produce walls, roofs, arches, tubes, circular apertures, etc. Special shapes are specifically made for specific locations within furnaces and for particular kilns or furnaces.

Refractory bricks are materials specifically designed for use in high-temperature applications, such as furnace linings, kilns, and boilers. They are made from a mixture of refractory materials, such as fireclay, alumina, magnesia, and other mineral oxides, that are capable of withstanding high temperatures without undergoing significant thermal degradation.

Refractory bricks are known for their high refractoriness, which refers to their ability to resist melting and other thermal degradation at high temperatures. They also have high resistance to thermal shock, which allows them to withstand sudden temperature changes without cracking or breaking.

In addition to their high-temperature resistance, refractory bricks also have excellent resistance to chemical attack and corrosion, making them ideal for use in harsh industrial environments. They are available in a range of shapes, sizes, and configurations to meet specific application requirements, and can be customized to provide a perfect fit for various furnace and kiln designs.

Refractory bricks are essential components in high-temperature processing and manufacturing, providing crucial support and protection to equipment and processes. They are typically used in applications such as furnaces, kilns, boilers, and other high-temperature equipment, and are selected based on specific performance requirements, including refractoriness, thermal shock resistance, and resistance to chemical attack.

Overall, refractory bricks are a critical component in a wide range of high-temperature applications, providing reliable performance and long-lasting protection in harsh industrial environments.
