摘要

Numerical investigation of grade change in two strand slab caster tundish during ladle changeover in continuous casting steelmaking process has been carried out using educational version of CFD software PHOENICS. Intermixed amount was first found out for bare tundish. Further, dams and weirs were introduced to see its effect on the intermixed amount as compared to that from bare tundish. Different grade specifications were adopted for the calculation of intermixed amount in terms of time for which the intermixed grades as per the specification were exiting through the outlet. While the intermixed length was seen to decrease with dam the placement of dam in the tundish, no significant improvement in terms of decrease in the intermixed length was observed with the use of weirs in the tundish.
