Tundish Nozzle

Tundish Nozzle Introduction:
Tundish nozzles usually comprise a zirconia inner nozzle (often referred to as a “zirconia insert”) with a lower grade outer body such as Alumina, Zircon or Bauxite. Tundish Nozzles are an integral part of Continuous Steel Casting process. The design of tundish nozzles vary according to the system manufacturer or the individual needs of the steel plant.


Tundish nozzle is a combination of inner core and exterior. The inner core is made of stabilized zirconia and zircon sand, producing through molding machines and high-temperature calcination. The exterior is made of zirconium and corundum, producing through molding machines and low-temperature baking. Tundish nozzle is located at the bottom of the tundish, it's the channel of liquid steel to flow from the tundish into the crystallizer. 


Tundish Nozzle Advantages:

1. Fast sliding, accurate, no bias current, steel leakage;

2. Good corrosion resistance, no obvious expanding, long service life, no bias current and dissipation;

3. Good thermal shock resistance and explosion resistance;

4.Changxing Refractory can make different products according to customer's requirement.

Tundish nozzle has the advantages of heat preservation, reduce the temperature of the outer surface of the nozzle, reduce the heat dissipation, reduce weight, increase strength, improve the service life, etc.

Tundish nozzle is an important part of continuous casting production. Whether the tundish nozzle exit aperture is kept constant is an important index to measure the product quality.It is usually measured in total usage time in actual production. Tundish nozzle has the properties of high refractoriness, good resistance to erosion, and can bear rushing scour etc.
