  • Patent number: 3941588
    Abstract: A method, compositions and articles are described for the direct addition of alloying metal to a molten metal to be alloyed, which provide more rapid dissolution of the alloying metal in the molten metal than has been possible heretofore. The alloying metal is added to the molten metal to be alloyed in finely particulate form in intimate admixture with a flux suitable for the purpose and finely particulate phenolic resin. The phenolic resin, in particle form, and preferably in the form of low density microballoons, is employed in an amount such that the ratio of the volume of the metalflux mixture to the volume of the microballoons is in the range from about 2:1 to about 12:1. The flux-alloying metal mixture contains about 3 to about 10% flux and about 90 to about 97% alloying metal, by weight of the flux-metal mixture. The compositions may be added to the molten metal bath in powder or lump form or may be incorporated in articles such as bags or briquettes containing the compositions.
