A novel ladle and method for spheroidizing molten iron is disclosed. A cover made of a porous body defining continuous blow holes is mounted at the upper portion of ladle main body containing spheroidizing material therein, and spheroidizing is effected by pouring molten metal into the ladle main body through the porous body cover. Alternatively, the cover is partly cut-away, and spheroidizing is effected by pouring molten metal into the ladle main body through the cut-away portion of the cover.
