Fused refractory bricks are special refractory bricks used in electric furnaces (such as glass melting furnaces, aluminum electrolytic cells, etc.), and are mainly used in extreme process environments that withstand high temperatures and chemical corrosion. The following is a detailed description of some common fused refractory brick types:
1. Alumina brick: Alumina brick is one of the most common fused refractory bricks. It consists of high-purity alumina as the main component and has excellent high temperature resistance, corrosion resistance and mechanical strength. Alumina bricks are divided into different grades, such as high alumina bricks, quality alumina bricks, super high alumina bricks, etc. You can choose the appropriate grade according to your needs.
2. Silicate brick: Silicate brick is a kind of fused refractory brick with silicate material as the main component. It has high temperature resistance and corrosion resistance, and is suitable for many electric melting furnace applications, such as glass melting furnaces and ceramic melting furnaces.
3. Zircon brick: Zircon brick is a kind of fused refractory brick with zircon (ZrSiO4) as the main component. It has excellent high temperature resistance, corrosion resistance and thermal shock stability and is suitable for applications such as high temperature glass melting furnaces and metal electrolytic cells.
4. Silicon carbide brick: Silicon carbide brick is a kind of electric fused refractory brick made of silicon carbide (SiC) particles as the main component. It has extremely high temperature resistance, corrosion resistance and thermal conductivity, and is suitable for special process environments such as high-temperature metal electrolytic cells and aluminum electrolytic cells.
5. Silicon nitride brick: Silicon nitride brick is a kind of electric fused refractory brick with silicon nitride (Si3N4) as the main component. It has excellent high temperature resistance, corrosion resistance and mechanical strength, and is suitable for special process environments such as high temperature metal electrolytic cells and aluminum electrolytic cells.
These are common types of fused refractory bricks that have different chemical compositions and performance characteristics for different electric furnace process environments. When selecting and using fused refractory bricks, appropriate materials should be selected according to specific process requirements, temperature range, corrosive media and other factors, and relevant industry standards and supplier recommendations should be followed.
