Tundish Nozzles are critical functional refractories used in continuous steel casting to control the flow of molten steel from the tundish into the mold. They operate under severe conditions, including high temperature, molten steel erosion, thermal shock, steel penetration and chemical corrosion.

We supplie a complete range of Tundish Nozzles, including Tundish Metering Nozzles, Tundish Upper Nozzles,Tundish Exchangeable Nozzles,Composite Slide Gate Plate Nozzles and Composite Nozzles,engineered for different tundish configurations and continuous casting requirements.

Our tundish nozzles can be manufactured from alumina-carbon, alumina-zirconia-carbon, zirconia-containing and other customized refractory compositions according to steel grade, casting speed, nozzle configuration and service conditions.

FAQ

1.What is a tundish nozzle?

A tundish nozzle is a refractory component used in continuous casting to provide a controlled passage for molten steel from the tundish to the mold.

2.What is an exchangeable tundish nozzle?

An exchangeable tundish nozzle is designed for a tundish flow-control system that allows the nozzle to be replaced or exchanged during operation according to the equipment configuration and casting procedure.

3.What materials are used for tundish nozzles?

Common materials include alumina-carbon, alumina-zirconia-carbon and zirconia-containing refractory materials. The optimum composition depends on steel grade, temperature, casting speed and casting sequence.

4.How can I choose the correct tundish nozzle?

The nozzle should be selected based on nozzle type, bore diameter, tundish design, steel grade, casting temperature, casting speed, casting sequence and slag chemistry.

5.Can Luming manufacture tundish nozzles according to drawings?

Yes. Luming provides customized and OEM tundish nozzles according to customer drawings, samples and technical specifications.

6.How long is the service life of a tundish nozzle?

Service life depends on steel grade, casting temperature, casting speed, nozzle material, bore diameter, slag conditions and casting sequence. Luming can recommend a suitable refractory grade based on your actual operating conditions.
