Product Description

Product Description
 
The Zirconia Metering Upper Nozzles are designed to facilitate the quick exchange of Sub-entry Nozzles (SEN), extending the service life of the tundish and reducing production costs. The bore of the tundish nozzle is made from sintered zirconia, which is wholly inlayed, providing superior anti-corrosion and anti-erosion properties. This enhances the working duration of the tundish and ensures better cooperation with stoppers, making it suitable for various continuous casting levels.
