Numerical Simulation of the Electromagnetic Continuous Casting for Clad Slab

In this paper,a new electromagnetic continuous casting process to prepare clad slab is presented.The influence of level direct current electromagnetic field on temperature and flow fields of the melt during the fabrication of clad slab were numerically studied by the engineering software ANSYS and FLUENT.The results indicated that when the magnetic flux density(B)was 0.15 T,the impact velocity and distance of the flow to the narrow face and underside of the dividing plate decreased remarkably.So the flow impact to the liquid pool was reduced.At the same time,the high temperature zone of the melt moved away from the narrow face and the dividing plate,and distributed more uniformly.The wider semi-solid arca next to the dividing plate was useful for 3003 and 4004 aluminum alloys to bond.
