Precision Flow Control: Our Upper Nozzles are engineered with precision to provide accurate and controlled flow of molten steel. They are designed to maintain a stable and uniform flow rate, ensuring consistent casting quality and reducing the risk of defects.

Excellent Thermal Resistance: The refractory material used in the Upper Nozzles exhibits excellent thermal resistance. It can withstand the high temperatures of the molten steel and the surrounding environment, ensuring long-lasting performance and minimizing the risk of thermal damage or failure.

Erosion and Corrosion Resistance: Our Upper Nozzles are designed to resist the erosive and corrosive effects of molten steel and slag. The refractory material is selected for its high resistance to erosion and chemical reactions, ensuring extended service life and maintaining dimensional stability.

 

 

 

Treatment of molten steel: Refractory nozzles used in the tundish are used to control the flow and uniformity of molten steel to ensure uniform mixing and degassing of molten steel in the tundish. The nozzle can adjust the velocity and direction of flow and improve the quality and purity of molten steel.

Inclusion control: The Refractory Nozzle Upper Nozzles for Tundish in the intermediate envelope can effectively reduce inclusion in the molten steel. The spray effect of the nozzle can promote the inclusion to the bottom of the tundish deposition, so that the surface of the molten steel can be purified.

Casting process optimization: The Refractory Nozzle Upper Nozzles for Tundish can be optimized according to different casting process requirements. The structure and size of the nozzle can be adjusted according to the specific requirements, so as to achieve the precise control of velocity, flow direction and injection effect, and improve the pouring effect and product quality.
