DESCRIPTION
Tundish nozzles are essential components in the steelmaking process. They regulate the flow of molten steel from the tundish to the mold during continuous casting, ensuring that the metal is free of impurities and has a smooth and consistent flow.
Tundish nozzles can be made from a variety of materials, including alumina, zirconia, and graphite, each with its own unique set of properties and advantages. Choosing the right tundish nozzle can significantly impact the quality of the final steel product.
A tundish nozzle that provides a smooth metal flow is critical to ensure a continuous and stable casting process. A nozzle that is well-designed and made from high-quality materials will reduce turbulence and prevent clogging, resulting in a more uniform and consistent steel product.
