摘要： A process for producing a semi-solidified slurry of an iron alloy including the steps of pouring a melt of an iron alloy into a semi-solidified slurry producing vessel 30 and cooling the melt therein to obtain a semi-solidified slurry having a crystallized solid phase and a residual liquid phase, wherein a hypereutectoid or hypoeutectic cast iron composition containing 0.8-4.3 wt. % C is used as a material, a melt of the composition is poured into the semi-solidified slurry producing vessel in a predetermined amount at a time, a temperature of the melt when poured into the semi-solidified slurry producing vessel is controlled to be not lower than a crystallization initiation temperature of the composition and not greater than a temperature that is 50° C. higher than the crystallization initiation temperature, and a cooling rate of the melt poured into the semi-solidified slurry producing vessel is controlled not to exceed 20° C. per minute.
