Introduction to Tundish Nozzle
A tundish nozzle is a critical component in the continuous casting process of steelmaking. It serves as a passage for molten steel to flow from the tundish to the mold at a controlled rate and in a specific manner. The quality and performance of the tundish nozzle directly affect the quality of the cast steel products, including factors such as surface finish, internal structure, and the prevention of inclusions. A well - designed and high - quality tundish nozzle can ensure a stable and smooth flow of molten steel, reduce turbulence, and minimize the risk of blockages and slag entrainment.
