Method for spherodizing molten cast iron and ladle for use in the spherodizing.

摘要

A novel method for spherodizing molten cast iron is disclosed. A cover made of a porous body containing continuous blow holes is mounted at the upper portion of ladle main body containing spherodizing material therein, and spherodizing is effected by pouring molten metal into the ladle main body through the porous body cover. Preferably the cover has a porous body containing continuous blow holes mounted and is partly cut away, and spherodizing is effected by pouring molten metal into the ladle main body through the cut portion of the cover. A ladle preferably used for practicing the novel method for spherodizing molten cast iron is also disclosed. <IMAGE>
