    Abstract: Apparatus and method for controlling fumes in an arc furnace. The fumes are collected by a circumferentially disposed duct whose cross-sectional area increases in the direction of flow. Fumes are introduced into the duct by ports or spaces in the roof of the furnace with the flow passage formed by the spaces or ports in the roof decreasing at the same rate as the duct crosssectional area increases.

    Abstract: An induction coil furnace system includes at least an active induction coil and a passive induction coil surrounding a furnace volume. The active induction coil is connected to an AC power supply, while the passive induction coil is connected in parallel with one or more capacitors forming an L-C tank circuit. The connections to the AC power supply and the one or more capacitors are optionally an interchangeable connection, such that the active coil can become the passive coil upon disconnection of the AC power supply and connection of the one or more capacitors. Likewise, the passive coil can become the active coil upon disconnection of the one or more capacitors and connection of the AC power supply. The active coil is selectively electrically connected to the passive coil via a separable electrical connection, whereupon separation, the active coil and the passive coil are electrically isolated.

    Abstract: A method of cooling an electric induction furnace for melting and holding a reactive metal or alloy is provided where the electric induction furnace has an upper furnace vessel and an induction coil in a modular inductor furnace is positioned below the upper furnace vessel with a melt-containing vessel positioned inside the induction coil with a gap between the outside surface of the melt-containing vessel and the inside surface of the induction coil that is used to circulate a cooling fluid for cooling the melt-containing vessel to inhibit leakage of the reactive metal or alloy melt from the melt-containing vessel. The melt-containing vessel can be integrated with a cooling system for cooling the melt-containing vessel. Modularity of the melt-containing vessel, induction coil and cooling system facilitates servicing of the modular inductor furnace without disassembly of the entire electric induction furnace.

    Abstract: The present invention relates to an electric channel inductor assembly. A nonremovable, hollow and nonmagnetic channel mold is used to form the one or more flow channels of the electric channel inductor assembly for electromagnetic circulation of a molten metal composition. A heated fluid medium is circulated in the hollow interior of the channel mold after the mold is situated in the inductor assembly to heat treat the refractory surrounding the exterior walls of the mold. After heat treatment a liquid is supplied to the hollow interior of the mold to chemically dissolve the channel mold prior to circulation of the molten metal composition.
