Submerged Entry Nozzle

Product Details

The submerged entry nozzle cooperates with the tundish nozzle, connects the tundish and the crystallizer, and transports the molten steel from the tundish to the crystallizer, while protecting the casting, preventing secondary oxidation of the molten steel.

The SEN we provide can be customised according to customer requirements, and our products have the characteristics of high temperature resistance, corrosion resistance and long service life.
