In this paper,a new electromagnetic continuous casting process to prepare clad slab is *** 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 *** 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 *** the flow impact to the liquid pool was *** 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 area next to the dividing plate was useful for 3003 and 4004 aluminum alloys to bond.

＜正＞Based on MHD theory, mathematical model of metal fluid flow in the mould installed electromagnetic field was established;SIMPLE code for computing fluid field was programmed using Visual C++6.0 software, adopting interleaving mesh and iterative routine of line-by-line with block amendment;the effects of level magnetic field （LMF） on metal fluid flow were researched. The results show that by imposing LMF, discharge velocity from the nozzle is suppressed, jet length is decreased, back flow zone in the center of the mould is reduced;that control effectiveness is obvious when magnetic flux density is more than 0.2T;that it is necessary to set dam board of about 20mm-30mm high in the upper port of the mould in order to avoid lateral flow of liquid-level due to applying EMBR;when the casting speed is faster, the effectiveness of EMBR is better. The cast metals that have different performance on two sides can cast continuously by pouring two molten metals of different chemical composition, because electromagnetic force can suppress the mixing of molten metals in the molten pool.
