  • System and method of melting raw materials
    Patent number: 9598747
    Abstract: A system and method for melting a raw material. The raw material is fed into an electrically conductive vessel. A plasma arc torch melts at least some of the raw material within the vessel to thereby create a molten material. An inductor, physically disposed adjacent the vessel, and electrically disposed in series with the vessel in operation, effects electromagnetic stirring of the molten material by interacting with the current of the plasma arc torch.
    Type: Grant
    Filed: September 18, 2013
    Date of Patent: March 21, 2017
    Assignee: RETECH SYSTEMS LLC
    Inventors: Robin A. Lampson, Robert E. Haun, Paul G. Meese, Matthew A. Charles, Edward C. Strout, Todd R. Telfer
