摘要： The disclosure relates to a method and apparatus for recycling, smelting, and refining waste metal material and low grade metal material. A magneto-plasma provides a high temperature for extracting metals. The magneto-plasma is comprised of an alternating current plasma superimposed upon a direct current plasma with the plasmas being confined by an externally applied axial magnetic field. The magneto-plasma is sustained with reduced voltage fluctuations across the plasma even when the background gas of the plasma is contaminated by the products from the smelting operation. The metal material being smelted is caused to melt by the high temperatures within the magneto-plasma which can be in the range of 10,000.degree. K. The metal material upon being melted into droplets is exposed to the high temperature of the magneto-plasma for a predetermined period of time as the droplets descend through the plasma. The length of the magneto-plasma is adjusted to obtain refining of the droplets of molten metal within th plasma. In addition, the lateral cross section of the length of the magneto-plasma is adjusted to enhance refining of the molten droplets.

摘要： A process is described wherein a material, such as particulate metal oxides, is treated with an arc discharge plasma under vacuum in the presence of a magnetic field running axially between the arc electrodes, wherein the plasma rotates symmetrically about a middle magnetic field, under conditions such that in a region the product of the electron gyration frequency Omega and time Tau , within which the average electron transmits its impulse to the plasma ions, is Omega Tau > 1 at about the middle of the magnetic field, and treated material, i.e., reduced metal, is recovered radially outside the region. Apparatus is described, for carrying out the process, including a discharge vessel, two spaced annular electrodes arranged symmetrically to the axis of the vessel, a magnetic coil enclosing coaxially the space between the electrodes, and means to introduce material axially through one electrode into the space.

摘要： Iron ore is continuously converted to steel by introducing the ore into a shaft furnace of substantially equal cross-sectional width and thus forming a column of the charge therein; introducing a reducing gas into the furnace and exposing the bottom portion of the charge column from below to the heat of an electric arc the source of which is centrally disposed in the bottom of the furnace and thus causing the gradual super-heating and melting of the bottom portion of the charge so as to form a dome-shaped cavity at the bottom of the charge column while the column gradually moves downward under the force of gravity and collecting and tapping the formed molten steel at the bottom of the furnace.

摘要： There is disclosed a process for desulfurizing transition metal alloys, particularly in a vacuum induction melting process where the absence of slag is desirable. The process is effected by adding any dilute calcium bearing binary alloy such as an alloy of calcium and nickel or an alloy of calcium and aluminum to the transition metal alloy while it is in the molten state and in contact with an atmosphere that is substantially free of oxygen.
