| Abstract: | In order to obtain cast metal of high quality, an investigation was carried out by simultaneous imposition of multi electromagnetic fields from the outside of a cold crucible copper mold. Sn 4.5%Pb as a simulator of high melting point metal was continuously cast under different conditions. The results show that multi electromagnetic fields can eliminate surface defects, and coarse columnar grains of the solidification structure is turned into equiaxed crystal with the increase of magnetic flux density. Moreover, finer equiaxed crystal structure is obtained when rapidly solidified sheet is fed into the mold during continuous casting. |
