Introduction to Tundish Nozzle
A tundish nozzle is a crucial 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. The quality and performance of the tundish nozzle directly affect the quality of the cast steel products, such as the surface finish, internal structure, and purity. High - quality tundish nozzles need to have excellent thermal shock resistance, corrosion resistance, and mechanical strength to withstand the harsh environment of high - temperature molten steel.
