ABSTRACT:
Metallurgically treated metal castings are produced using a consumable plug assembly made of a meltable material which is placed in a reaction chamber in an open treating basin and above a passage to a molding cavity. The consumable plug assembly has physical and chemical characteristics which maintain the plugged relationship for a preselected retaining period. All of a treating material is placed on the plug in the reaction chamber prior to metal pouring so as to react directly with the poured metal in a non-dynamic way.
