Tundish Nozzles

Tundish Nozzles are mainly with Zirconium inserted, featuring high refractoriness, and low expansion rate, superior resistance to erosion/corrosion and thermal shock and long service life. According to customers’ different needs, ZA can provide various sizes and specifications.
Tundish continuous casting machine.
Widely used throughout metallurgical industry
Tundish nozzles are basically used for controlling the flow of steel from the Tundish to the Continuous Casting equipment. Different kind of tundish nozzles include Alumina, Alumina Carbon, Zirconia Alumina Nozzles.
Tundish nozzle is divided into two types: argon blowing and non-argon blowing. The tundish nozzle is embedded in the seat brick at the bottom of the tundish and used in conjunction with the stopper. The tundish nozzle is mainly used to adjust the flow of molten steel entering the mold, and argon can be blown through the inner wall to prevent the nozzle from being blocked.
