What do the three letters of fused cast AZS bricks mean?

Fused cast AZS bricks are also called fused refractory bricks and fused zirconium corundum bricks. The English abbreviation AZS mainly represents the initials of the main elements Al2O3, ZrO2, and SiO2. The arrangement order is based on the content of the elements, among which the content of alumina is about 48%, the content of chromium oxide is about 30%, and the content of silicon dioxide is generally about 20%.

Characteristics of fused cast AZS bricks

AZS refractory bricks have high fire resistance, thermal shock resistance and corrosion resistance, and are often used in high temperature environments in the glass, steel and ceramic industries. In glass kilns, they are used in key locations to ensure stable operation of the kiln and improve production efficiency. Аммо, the unit price is relatively high, so the budget and kiln stability must be considered when choosing.

Application of AZS refractory bricks

The refractory temperature of AZS refractory bricks can reach above 1790℃, the load softening temperature is generally above 1550-1650℃, the compressive strength can reach above 80Mpa, and it has good thermal shock stability and corrosion resistance, so it is often used in high-temperature environments such as pool kilns and electric melting furnaces in the glass manufacturing field, as well as slideways in the steel industry and kilns for producing sodium silicate.
In glass kilns, AZS refractory bricks are often used in key parts of glass kilns, such as the bottom of the pool, the wall of the pool, the upper structure and the feed channel, which are often eroded and corroded by materials. It can ensure the normal operation of high-temperature kilns and improve glass quality and production efficiency.
In the metallurgical industry, AZS refractory bricks can be used to line degassing ladles, stainless steel ladle linings, rolling ladle linings, ва ғайра. Due to its excellent wear resistance and corrosion resistance, it can reduce the wear of the furnace wall by the slag in the ladle and the erosion of the molten steel, and extend the service life of the ladle.
In the ceramic industry, AZS refractory bricks can be used in key parts of ceramic firing furnaces to resist high temperature erosion and provide a stable working environment for ceramic firing.
