Fluid Flow and Heat Transfer Behaviors under Non-Isothermal Conditions in a Four-Strand Tundish

In the continuous casting process, fluid flow of molten steel in tundish is a non-isothermal state. Because geometric shape and process parameters multi-strand tundish, behavior each strand quite inhomogeneous, difference temperature, composition inclusion content between great, which directly affects quality products. this paper, flow, heat transfer phenomena trajectories four-strand with without flow-control devices (FCDs) are investigated using water model numerical simulation isothermal conditions. The results show that natural convection has significant influence on pattern temperature distributions tundish. Without FCDs, average residence times obtained by model, mathematical were 251.2 s, 263.3 s 266.0 respectively, dead zone volumes 21.51%, 29.26% 28.21%, respectively. With 293.0 304.0 305.2 43.98%, 50.23% 52.78%, characteristics different Compared conditions, closer to trial showed characteristic, conditions can better reflect actual behaviors
