Heavy refractory brick is a high-performance refractory material with high density and excellent refractory performance. According to different components and uses, heavy refractory bricks can be divided into various types and specifications. The following is a detailed introduction of common types of heavy refractory bricks and their specifications:
1. High alumina heavy refractory brick
High-alumina heavy refractory bricks use high-purity alumina (Al2O3) as the main component. Common specifications include:
Conventional specifications: 230mm×114mm×65mm, 230mm×114mm×75mm, etc.
Special specifications: can be customized according to requirements, such as curved bricks, trapezoidal bricks, etc.
2. Silica brick
Silica bricks are mainly composed of silicon dioxide (SiO2), which has good corrosion resistance and high temperature resistance. Common specifications include:
Conventional specifications: 230mm×114mm×65mm, 230mm×114mm×75mm, etc.
Special specifications: customized according to needs, such as curved bricks, trapezoidal bricks, etc.
3. Zirconia brick
Zirconia bricks use zirconia (ZrO2) as the main component, which has extremely high fire resistance and corrosion resistance. Common specifications include:
Conventional specifications: 230mm×114mm×65mm, 230mm×114mm×75mm, etc.
Special specifications: can be customized according to requirements.
4. Magnesia brick
Magnesia bricks use magnesium oxide (MgO) as the main component, which has excellent fire resistance and mechanical strength. Common specifications include:
Conventional specifications: 230mm×114mm×65mm, 230mm×114mm×75mm, etc.
Special Specifications: Customized as required.
5. Silicon carbide brick
Silicon carbide bricks use silicon carbide (SiC) as the main component, which has excellent high temperature resistance, corrosion resistance and wear resistance. Common specifications include:
Conventional specifications: 230mm×114mm×65mm, 230mm×114mm×75mm, etc.
Special Specifications: Customized as required.
The types and specifications of these heavy refractory bricks are usually used in high-temperature industrial fields such as metallurgy, glass, chemical industry, and electric power. Different specifications and types can be selected according to specific use conditions and process requirements to ensure the normal operation and durability of the equipment.
