Abstract

In 21st century due to global market steelmakers are facing tough competition to sell product and for that reason stringent quality steel is required to manufacture. As tundish is an important buffer before the steel cast to semifinished product so it is the aim of the metallurgist over the last three decades to enhance the performance of this reactor. In this regard slag eye formation, slag metal emulsifications, turbulence during metal transfer operation at the time of ladle changing period and inclusions generations from re-oxidation have adverse effects towards production of high purity liquid steel. To combat these phenomena researchers have tried to develop different shrouds and impact pads to control the turbulence within the steel melt during steady and unsteady state operations. But no technology is able to reach to the ultimate success. In the current context a new concept has been developed called “Vacuum Shroud (VS)” which studied numerically by using ANSYS FLUENT software to explore the effect of currently innovative flow control device in comparison with others previously developed technology towards improvement of the tundish performance. It is found that the novel device is highly capable to replace turbostop and will reduce the mentioned problems forever.
