Abstract
A new process for swling flow generaton in the submerged entry nozzle (SEN) in continuous casting process of steel was proposed. A rotating electromagnetic field was set up around the SEN to induce swirling flow by Lorentz force. The flow and temperature felds in the SEN and round bllet mold with electromagnetic swirling were numerically simulated and then verified by the electromagnetic swirling model experiment of low meting point alloy. The effects of divergent angle of the SEN on the flow and temperature fields in mold with electromagnetic swling were investigated. The electromagnetic swrling flow generator (EMSFG) could effectively induce swirling flow of molten steel in the SEN, which consequently improved greatly the flow and temperature fields in the mold. Below the nozzle outlet in mold, with the increase of divergent angle, the stream of bulk flow diverged more widely, the high temperature zone shifted up, and the temperature field became more uniform. Above the nozzle outlet in mold, with 350 A electromagnetic swirling, when the divergent angle of the SEN increased, the upward flow velocity and the meniscus temperature first increased and then decreased. With a divergent angle of 60°, the upward flow velocity and meniscus temperature reaced the largest value.
