Tundish Metering Nozzle
Product Description:
The Zirconic nozzle size cancontrol the casting speed. According to the customers’ requirement,we can supply inlaying,compound and different types of nozzle products.
Tundish metering nozzles for continuous steel casting are made of zirconia and baddeleyite, formed by high tension and baked in high temperature when stablized by special technology. Different sizes and types of zirconia metering nozzles are designed and made according to users’ different steel-making conditions and requirements.
Metering nozzles are mainly with Zirconium inserted, featuring high refractoriness, and low expansion rate, superior resistance to erosion/corrosion and thermal shock and long service life. According to customers’ different needs, AGMC can provide various sizes and specifications.
Features of Tundish Zirconia Metering Nozzles for Continuous Casting Process:
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
