Top 10 tundish shroud Factory in the world 2025

Introduction of Tundish Shroud

A tundish shroud, also known as a submerged entry nozzle (SEN), is a critical component in the continuous casting process of steel. It is a refractory tube that connects the tundish, which is a buffer vessel holding molten steel, to the mold where the steel solidifies into semi - finished products such as slabs, billets, or blooms. The main functions of the tundish shroud are to prevent the re - oxidation of molten steel by isolating it from the atmosphere, control the flow of molten steel into the mold, and reduce the splashing and turbulence of the steel stream, which helps to improve the quality of the final steel products.
