Abstract
A process for the production of a semi-solidified iron alloy slurry having a crystallized solid phase and a residual liquid phase, wherein a material having a hypoeutectic cast iron composition is used, and an additive agent having a boiling point that is lower than at least a crystallization initiation temperature of primary crystals of the material is added to a melt of the material when the melt temperature is within a specific temperature range of not lower than the crystallization initiation temperature of the primary crystals and not greater than a temperature that is 50° C. higher than the crystallization initiation temperature, to thereby simultaneously conduct the stirring of the melt by the boiling of the additive agent and the cooling of the melt to a temperature falling within a semi-solidification temperature range thereof.
