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.

Systems and methods of threading a metal substrate on a rolling mill include receiving a coil of the metal substrate. The method also includes uncoiling the metal substrate from the coil while the coil and guiding the metal substrate to a work stand of the rolling mill with a threading system.

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.

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.
