Systems and methods of non-contact tensioning of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor. The magnetic rotor is spaced apart from the metal strip by a first distance. The systems and methods also include tensioning 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 tensioned in an upstream direction or a downstream direction. In other aspects, rotating the magnetic rotor induces a magnetic field into the metal strip such that a force normal to a surface of the metal strip is applied to the metal strip.

Systems and methods of hot forming a metal blank include receiving the metal blank at a heater and positioning the blank adjacent a magnetic rotor of the heater. The systems and methods also include heating the metal blank through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal blank such that the metal blank is heated.

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.

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.

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.

A feeding system for delivering elongate workpieces to a forming machine includes a feeding apparatus with a coil-based workpiece supply receiving device and a straightening system with two adjustable rolling/straightening apparatuses to straighten the workpiece before forming. A measurement unit measures residual curvatures on the straightened material and establishes measurement data representing the residual curvature. A cutting device separates rod-shaped portions of a predetermined length from the straightened material. The measurement unit includes a measurement apparatus for receiving a rod-shaped portion in a measurement position and is configured for specific measurements associated with the straightening planes of the rolling/straightening apparatuses, enabling accurate assessment of residual curvatures in the workpiece.
