抄録

In this paper, the EMBR technique was applied in producing the bimetallic slab on the basis of numerical simulation with the software of ANSYS. By suppressing the mixture of two kinds of molten metals in the mold of continuous casting strand with a level DC electromagnetic field, the bimetallic slab of Al–12wt%Si and Al–10wt%Mg was obtained. The slab was analyzed by XRD, EPMA and metalloscope. The results showed that there were same compositions on two sides of the slab obtained without electromagnetic field and there were different compositions on two sides of the slab obtained with electromagnetic field of 0.15 T, no obvious interface was found in the slab. The conclusion indicated that the electromagnetic field restrained the flow of the melt effectively.
