Abstract
Last decade steel productions around the world have increased significantly. But there is a high demand of clean steel in domestic as well as international market. For that reason currently many research is going on in this direction. In present investigation, few innovative shrouds were developed conceptually which can be useful in terms future perspective for production of clean and green steel within the last metallurgical reactor tundish. Vacuum shroud and Novel Centrifugal Shroud with argon purging can eliminate formations of tundish open eye (TOE) during ladle transfer operation. 3D Numerical simulation by using ANSYS FLUENT software shows that these flow control products will able to reduce re- oxidation of liquid steel by suppressing slag eye formation or protecting the reaction of liquid steel from ambient air by covering inert argon gas within the tundish vessel.
