Abstract of the Disclosure A process or method of and apparatus for the in-ladle treatment of molten base metal iron with a nodularizing agent (e.g., a magnesium bearing alloy) so as to produce substantially uniform spheriodal graphite in the iron. The process involves placing a desired quantity of the nodularizing agent in a reaction chamber in a treatment ladle, the latter having a main chamber, a charging and filling passage leading to the reaction chamber, and one or more passages leading from the reaction chamber to the main chamber of the ladle. Molten base metal iron is then poured into the reaction chamber via the charging and filling passage thereby to effect a reaction between the nodularizing agent and the molten base metal. A hydrostatic pressure head of the molten base metal is rapidly established over the reaction chamber of sufficient depth thereby to minimize the vaporization of the nodularizing agent and to maximize the recovery of the nodularizing agent in the base metal. The base metal with the nodularizing agent dissolved and mixed therein is then permitted to flow into the main chamber via the passages. The base metal with the nodularizing agent therein is held in the main chamber for a time sufficient to convert the base metal into a matrix which when solidified is populated with spheroidal graphite. The apparatus of this invention relates to a ladle in which the above-identified process can be carried out.
