摘要：
For the special casting environment of large round bloom mold with four-hole nozzle, the reasonable choice of mold electromagnetic stirring (M-EMS) location is of great significance to the quality control of bloom. In this study, the four-hole nozzle arc continuous casting of phi 600 mm-large round bloom is taken as an example, a 3D mathematical model of liquid steel flow is built, and the solidification and heat transfer under M-EMS is established. The optimum M-EMS position was obtained as Z = 600 mm, which is enhanced flow rates, shell uniformity, and brittle interval width, and offers valuable insights for improving casting quality.
