摘要： A compact heat treatment line can include a short heating zone capable of rapidly bringing a metal strip to a suitable solutionizing temperature through the use of magnetic rotors, such as permanent magnet magnetic rotors. A fast and efficient soaking zone can be achieved as well, such as through the use of magnetic rotors to levitate the metal strip within a gas-filled chamber. Magnetic rotors can further levitate the metal strip through a quenching zone, and can optionally reheat the metal strip prior to final coiling. Magnetic rotors used to heat and/or levitate the metal strip can also provide tension control, can facilitate initial threading of the metal strip, and can cure coatings and/or promote uniformity of coatings/lubricants applied to the metal strip without overheating. Such a heat treatment line can provide continuous annealing and solution heat treating in a much more compacted space than traditional processing lines.

摘要： Systems and methods of pre-ageing of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor of a reheater. The systems and methods also include heating the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is heated.

摘要： Apparatus and method are provided for electric induction heating and melting of a transition material that is non-electrically conductive in the solid state and electrically conductive in the non-solid state in an electric induction heating and melting process wherein solid or semi-solid charge is periodically added to a heel of molten transition material initially placed in a refractory crucible. Induction power is sequentially supplied to a plurality of coils surrounding the exterior height of the crucible at high power level and high frequency with in-phase voltage until a crucible batch of transition material is in the crucible when the induction power is reduced in power level and frequency with voltage phase shifting to the induction coils along the height of the crucible to induce a unidirectional electromagnetic stir of the crucible batch of material.

摘要： A cold crucible induction melting furnace is provided with a plurality of segments separated by a plurality of slits that surround a bottom member which together form the melting chamber. Each lower end of each segment is overlapped with and spaced from a short part of a vertically extending side wall of the bottom member so as to form a horizontal gap there between. A radially and outwardly extending flange protrudes from the bottom member side wall below each segment lower end to form a lower gap there between. An induction coil is disposed around and spaced from an outer face of the segments with a lower end adjacent to each of the lower segment ends and an upper end adjacent to an upper part of each segment that is in turn connected with an adjacent upper segment part to form a short circuited part. The radial thickness of each segment from the upper end of the coil to the lower end of the segments is the same and the magnetic flux generated by the induction coil passing through the lower gap and the horizontal gap provides increased magnetic flux density at least adjacent to the region adjacent to the bottom member and the lower ends of the segments.

摘要： A system for damping oscillatory and spinning motions induced in an electromagnetically levitated material. Two opposed field magnets are located orthogonally to the existing levitation coils for providing a DC quadrupole field (cusp field) around the material. The material used for generating the DC quadrupole field must be nonconducting to avoid eddy-current heating and of low magnetic permeability to avoid distorting the induction fields providing the levitation.

摘要： An apparatus and method for inductively melting a quantity of metal, without having to contain the metal in a crucible, is described. The solid metal to be melted is placed within a first induction coil excited by an alternating current and adapted to provide a greater electromagnetic force towards the lower portion of the quantity of metal. The solid metal rests on a support, having an opening therethrough, which also comprises means for keeping the support at a low temperature relative to the metal as it melts. When energy in the form of the alternating current is provided to the coil, the metal melts from the top downward, but the concentration of electro-magnetic force towards the bottom of the metal causes the liquid metal to retain a cylindrical shape. A non-varying electromagentic field is applied to the quantity of metal to minimize violent stirring of the molten portion of the quantity of metal caused by the time-varying field.

摘要： A non-contact heating apparatus uses a series of rotating magnets to heat, levitate, and/or move metal articles therethrough. A first series of rotating magnets heats the metal article to a desired temperature. A second series of rotating magnets levitates the metal article within the heating apparatus and maintains desired tension in the metal article, including urging the metal article through the heating apparatus. The heating apparatus can extend sufficiently far to soak the metal article at the desired temperature for a desired duration. The rotating magnets can be positioned outside of an electrically non-conductive, heat resistant chamber filled with an inert or mildly reactive gas, through which the metal article passes in the heating apparatus.
