Abstract
Mold electromagnetic stirring (M-EMS) has been widely used in many continuous casters. In order to have a deep insight into the collision-coalescence among inclusions under M-EMS by a Eulerian approach, the effects of Archimedes electromagnetic force on the inclusion are expressed by three-dimensional Archimedes electromagnetic slipping velocity and Archimedes electromagnetic collision. Numerical results show that a turbulent collision is the most important factor to cause inclusions to collide with each other, Archimedes electromagnetic collision has a minor effect, Stokes collision is the third factor, and Brownian can be ignored. In the case of M-EMS, there are two recirculation zones above and below the M-EMS central cross-section, and the inclusion spatial distributions have the inverted U-shape.
Highlights
As a vital process in steel production, curved continuous casting is applied in many steel companies because of low-energy consumption, high efficiency and metallic yield [1,2]
Numerical simulation is a popular method because it can provide the detailed information about metallurgical process, and it is not limited by the high temperature condition and costly expense

Summary
As a vital process in steel production, curved continuous casting is applied in many steel companies because of low-energy consumption, high efficiency and metallic yield [1,2]. The inclusion movement is affected the electromagnetic force (Archimedes electromagnetic force [4]), which hascasting the process similar problems about the inclusion behavior in a continuous. Some someimportant important problems about the inclusion behavior in a continuous casting characteristics to the buoyancy (Archimedes force) of inclusion particle in molten steel. The inclusion movement is affected the process are far from being solved. The among collision among caused inclusions caused by stirring (EMS),electromagnetic but fewis papers refer to distribution in the curved continuous caster electromagnetic force called as Archimedes collision.
