Refractory Zirconia Nozzle

Long Keter manufactures a comprehensive range of zirconia based TUNDISH METERING NOZZLE used for the continuous casting of steel.

It is a composite nozzle for reasons of economy.

The composite nozzlew are manufactured without the use of cement jointing, using an insert and pressed outer body. This method of manufacture provides a reliable system with no risk of steel leakage between the insert and outer body.

Upper nozzle(Stationary nozzle)

is located within the tundish lining and conveys steel to the controlling exchangeable nozzle,

which determines the steel flow. The stationary nozzle must be capable of withstanding long sequence times.Our Upper nozzle that incorporates a ultra-high densityLKZN-M or LKZN-H insert.

The insert provides excellent erosion resistance and can provide extended casting sequence times.The lower surface of the stationary nozzle is ground to exacting tolerances to ensure maximum surface contact between the two nozzle components.

Lower Nozzle (EXCHANGABLE)

is located within an assembly that is fixed to the bottom of the tundish.The design of the exchangeable nozzle can vary according to the system manufacturer.

We supplying a range of zirconia inserts and composite nozzle designs for the exchangeable metering of steel. Zirconia inserts can be supplied for on-site assembly into metallic holding blocks where cementing, grinding, size banding and on site drying are required prior to use.

It was manufactured by both cast process of fine grained alumina method or presse process.

Our nozzles suitable for several nozzle changer systems listed as below

• Concast - CNM

• Danieli - FNC

• Interstop - MNC

• Krosaki – OTNC

• Vesuvius – CNC/SYS120
