Fused refractory brick is a high-temperature refractory material used in electrolytic aluminum, silicon and other industries. According to different chemical composition and physical properties, fused refractory bricks can be divided into the following categories:
1. Alumina fused refractory brick: made of alumina as the main raw material, it has excellent high temperature stability, corrosion resistance and mechanical strength, and is widely used in electrolytic aluminum houses, silicon furnaces and other equipment.
2. Silicate fused refractory brick: made of silicate as the main raw material, it has good corrosion resistance, waterproof performance and certain wear resistance, and is widely used in high temperature, acid and alkali medium environments such as glass kilns .
3. Ferrosilicon fused refractory bricks: contain a relatively high proportion of silicon and iron elements, have excellent fire resistance, high temperature stability and corrosion resistance, and are widely used in iron and steel smelting and other industries.
4. Silicon nitride fused refractory brick: It is made of silicon nitride particles through fused technology. It has very high temperature resistance, high strength, corrosion resistance and good thermal conductivity. It is a new type of high-efficiency brick. Fused refractory bricks.
5. Silicon carbide fused refractory brick: It is made of silicon carbide powder through electric melting technology. It has extremely high fire resistance, wear resistance and corrosion resistance, and is widely used in metallurgy, ceramics, machining and other industries.
In short, different types of fused refractory bricks have their own advantages and disadvantages, and can be selected according to different use environments and requirements.
