Description of Continuous Casting Refractories Submerged Entry Nozzle SEN:

The submerged nozzle is a pouring refractory casing installed at the bottom of the intermediate tank in continuous steel casting equipment and inserted below the liquid level of the mold steel. The main function of the immersed nozzle is to prevent secondary oxidation of the intermediate tank injection flow and splashing of molten steel.
The main function of the submerged nozzle is to prevent secondary oxidation of the tundish tank injection flow and splashing of molten steel; to prevent the mold slag from being involved in the molten steel; and to improve the flow state and heat flow distribution of the injection flow in the crystallizer. This promotes the uniform growth of the billet shell in the crystallizer, which is beneficial to the elimination of gas and inclusions in the steel.

Submerged Nozzle can protect the molten steel from oxidation when it flows into the crystallizer from the tundish, evenly distribute the molten steel into the crystallizer and control the flow state of the molten steel in the crystallizer, with good slag resistance, anti blocking, long service life and low accident rate.

Performance Characteristics of Our Submerged Nozzle Continuous Casting Refractories
Our submerged entry nozzle has the following characteristics:
1.Good sealing: It has a good fit with our plug products, and the sealing performance is good after the stopper and the nozzle are
closed.
2.Anti-erosion: Advanced material formulation to effectively resist the physicochemical effects of the melt.
3.Antioxidant: Advanced anti-oxidation mechanism to ensure good protection of graphite in products.
4.High temperature resistance:1770 °C5.High strength: high-quality materials, high-pressure pressing, reasonable combination, high temperature strength, scientific
product design, high anti-scour ability.
6.Long service life: ductile iron casting life is generally not less than 48 hours, gray iron casting is generally not less than
72 hours.
