Abstract: 491,528. Alloys. HUNTZICKER, P. March 5, 1937, No. 6602. [Class 82 (i)] Alloying constituents are mixed with molten metal, for example iron or steel, by allowing the metal and alloying constituents to flow together down a receiving passage, and from the bottom of this passage into an adjacent body of metal at a point below the surface of the metal. The alloying constituents thus pass, submerged, through a long distance in the hot metal, clear of slag, and are completely melted before reaching the adjacent body of metal, with which they are intimately mixed by the action of the metal entering from the passage and by convection currents. In the apparatus shown, alloying constituents are supplied from a feeder 12 to the metal passing down the spout 11 of a cupola, the mixture falling into a passage 18 formed in the ladle 13, and passing through an outlet 19 in the bottom of the passage into the body of metal in the ladle.- Alternatively, the usual outlet passage 16 of the ladle may be employed in place of the passage 18 by turning the ladle round, or the mixture may be received in a refractory tube arranged vertically in a ladle. A furnace forehearth and a pouring spout adapted for use in the process are also shown.
