What Is a Tundish Nozzle?
A tundish nozzle meters steel from the tundish during continuous casting. This note covers the alumina body, the zirconia insert and the bore.

Tundish Nozzle Manufacturer: What Steel Plants Should Check
A short checklist before you place a tundish nozzle order: drawing, bore, which zirconia sheet, and export packing.
Tundish Nozzle Manufacturer in China
ZhengZhou Nuo Heng Refractory Materials Co.,Ltd makes tundish nozzles in Zhengzhou for export to Europe, the United States, Brazil and more than 25 markets.
Drawing-Based Tundish Nozzle Production
The nozzle is made from your drawing: bore, length and outer profile, then the zirconia insert or the quick-change body.
How to Order Custom Tundish Nozzles
Send the drawing, the bore and the plant country. NUOHENG quotes that nozzle, including sizes outside 10–16.5 mm.
Request a Quote for a Custom Tundish Nozzle
Send the bore or the drawing. NUOHENG replies with a quotation for the tundish nozzle, the zirconia insert or the quick-change nozzle.
Tundish Nozzle Dimensions and Bore Sizes
Bore is only one dimension. Length and outer profile still have to match the tundish well.
How to Choose a Tundish Nozzle Bore Diameter
Start from the bore on the caster, not from a catalogue average. The TDS list runs from 10 mm to 16.5 mm.
Tundish Nozzle Replacement: Drawing and Dimension Checklist
Before a repeat order, confirm bore, length, outer profile and which nozzle drawing is current.
Tundish Nozzle for Continuous Steel Casting
The tundish nozzle meters steel between tundish and mould. Bore, insert and drawing decide the piece.
Alumina-Based Tundish Nozzle for Continuous Casting
The outer body on the tundish nozzle TDS is an alumina refractory. These are the typical figures, kept apart from the zirconia insert.
Tundish Nozzle Application in Continuous Casting
On a continuous caster the tundish nozzle meters steel from the tundish. The bore, the insert and the seat decide the fit.
Zirconia Insert for Tundish Nozzles
The insert is the bore piece. Keep the dedicated specification apart from the typical line on the tundish nozzle TDS.
Zirconia Tundish Nozzle Insert: Technical Guide
Use this guide when a quality sheet asks for ZrO₂, density and porosity of the tundish nozzle insert.
Tundish Quick-Change Nozzle: What Buyers Should Confirm
Confirm the drawing and assembly size. The refractory chemistry follows the tundish nozzle TDS. The changer geometry does not.
