Features
zirconia tundish metering nozzle for continuous casting is made of zirconia and imported baddeleyite,formed by high tension and baked in high temperature when stablized by special technology. Different sizes and types of zirconia nozzles for steel making are designed and made according to users' different steel-making conditions and requirements.
1.Low expansion, supprior resistance to erosion/corrosion and thermal shock cycling.
2.Long and extended casting sequence times
3. Controlled and stable casting speed
4.Resistance to oxygen lancing
5.changeless diameter and lasing long.
Application
In casting steel, zirconia tundish metering nozzle for continuous casting is mainly used in successive-casting intermediary small square adobes, big square adobes, rectangle adobes and small board adobes.
