Gesinterte Zirkonkorundsteine werden auch als keramisch gebundene Alumosilizium-Zirkonsteine bezeichnet. Compared with fused zirconium corundum bricks, the chemical composition of sintered AZS bricks is similar. Jedoch, it has the advantages of containing no carbon, low glass phase content, einheitliche Struktur, keine Lunker, und gute Thermoschockstabilität und Korrosionsbeständigkeit.
The use of sintered AZS bricks in glass kilns
It has good resistance to alkali vapor and thermal shock. It is mainly used in the flame space of glass kilns, the regenerator bricks, and the upper grid body. It can also be used in the bottom or forehearth of float glass kilns and daily glass kilns—big bricks.
