Modelling steel flow in a three-strand billet tundish using a turbulence inhibitor

A three-strand tundish belonging to a billet easter was water modelled and plant trials were performed to compare the performance of a pouring box and a turbulence inhibitor in terms of melt flow parameters and steel cleanlin ess. A tailor made turbulence inhibitor for this tundish is useful to accomplish with flow control of fluid turbulence and even melt redirection to all str ands. The turbulence inhibitor helps to decrease nitrogen pickup during lad le changes and to float out inclusions towards the covering slag. As a cons equence, rod operations to take of alumina deposits from nozzle walls are c onsiderably decreased using a turbulence inhibitor.
