Abstract (en)
A method and apparatus for rheocasting (slurry casting) molten metal employ a stirring chamber (26) located upstream of a casting mold (34). Electromagnetic stirring is employed in both the stirring chamber and the casting mold. Structure (46)+(47) is provided for minimizing secondary recirculating flows in the molten metal as it flows downstream through the apparatus, for preventing hangers and for eliminating the columnar dendritic zone at the periphery of the casting. The efficiency of utilization of the magnetic field is optimized as if the agitation required for producing a desired fine, spheroidal, degenerate dendritic grain structure in the solidified casting. <IMAGE>
