A predetermined amount of molten metal 12 is supplied to a heat-insulating crucible 18. After that, a chill block 46, which is cooled to a predetermined temperature of not more than a temperature of the molten metal 12, is immersed and rotated in the molten metal 12. Accordingly, the molten metal 12 is agitated while being cooled to give no directivity of cooling. It is possible to obtain semisolidified metal 20 which is formed into slurry uniformly and effectively as a whole. The semisolidified metal 20 is discharged from the heat-insulating crucible 18, and it is supplied to a forming machine 22 to apply a forming treatment thereto. Accordingly, it is possible to produce the desired slurry efficiently and economically.
