Introduction to Tundish Shroud
A tundish shroud is a crucial refractory component in the continuous casting process of steelmaking. It is used to connect the tundish and the mold, providing a controlled passage for the molten steel to flow from the tundish into the mold. The main functions of the tundish shroud include preventing the re - oxidation of molten steel by isolating it from the air, reducing the splashing of molten steel, and ensuring a stable and uniform flow of molten steel into the mold, which is essential for the quality of the final steel products.
