Introduction to Tundish Shroud
A tundish shroud is a critical component in the continuous casting process of steel. It serves as a protective conduit between the tundish and the mold, preventing the molten steel from coming into contact with the surrounding air. This helps to avoid oxidation, nitrogen absorption, and other impurities from entering the steel, thereby improving the quality of the final steel product. The tundish shroud also plays a crucial role in controlling the flow rate and direction of the molten steel, ensuring a stable and uniform casting process.
