Abstract

Roturbo, multi-mode meniscus electromagnetic stirring (MODE-EMS) in tundish and flow controlling system is the advanced product. The unique magnetic turbo-circuit design and control technology, the product can automatically realize many stirring modes: single/turbo rotation mode, acceleration mode, deceleration mode, two-zone turbo mode, double-helix acceleration mode and so on. By using the metallurgical data packet, the required stirring position, modes and parameters can be switched according to the steel grades, the strand section and the quality requirements. So, electromagnetic stirrer for meniscus is installed on the mold the continuous caster. The strong Multiphysics coupling are studied with heat transfer or Navier-Stokes interface for induction heating or fluid flow control. In the case if the of laminar flow steel depth δ (penetration depth of the electromagnetic field inside the material) is very small compared to the characteristic dimension (e). A surface Impedance is set up and we do not need to resolve in detail the interior volume. Regarding, a thin conductive layer (e < δ), the layer is described only by a surface with a two way boundary condition. The electromagnetic action zone covers the meniscus. Mainly used to improve surface and subsurface quality of the bloom / slab. It is one of the key metallurgical equipment’s for continuous casting of special steel with high surface quality requirements, such as EV-cars and household appliances [1]. Roturbo MODE-Electromagnetic (MODE-EMS) processes are good candidates for energy saving and CO reduction demands. In metallurgy industry, it leads to productivity improvement, maintenance reduction and safety integration.
