Compact continuous annealing solution heat treatment

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.

Magnetic levitation heating of metal with controlled surface quality

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.

Non-Contact Magnetic Steering

A non-contact steering device includes one or more magnetic rotors positioned near a metal strip. Each rotor includes one or more permanent magnets and rotates to impart a changing magnetic field on the metal strip passing nearby. The magnetic rotors can rotate around an axis of rotation that is parallel to the longitudinal direction of travel of the metal strip. The magnetic rotors can be positioned to impart forces on the strip in any combination of laterally, vertically, or longitudinally. A control mechanism can control the rotor speed, rotor direction, vertical position of the rotors, vertical spacing between rotors, and/or lateral position of the rotors. In some cases, the control mechanism can be coupled to sensors, such as a light curtain and a laser distance sensor, in order to provide closed loop feedback control of a metal strip passing through the non-contact magnetic rotor steering device.

Coiling device with asymmetric cooling of the coiled strip

For a rolled metal strip, in particular a steel strip; a drive roller unit deflects the metal strip from a first transportation direction to a second transportation direction, and the strip is then fed to a coiler. The metal strip is coiled in the coiler to form a coil having a coil diameter. Plastic deformation of an end portion of the metal strip is caused such that the end portion in its uninfluenced state is curved at a curvature radius. The plastic deformation of the end portion (8) is at least partially caused by an asymmetric impingement with a cooling medium (21) on the sides of the end portion (8). The impingement of the end portion (8) with the cooling medium (21) is performed across a length of the end portion (8) that is longer than half the outermost coiling of the coil (6) but smaller than the outermost coiling of the coil (6).
