Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 62 / 173,097, filed June 9, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates generally to the processing of metal strip, and in particular to the steering or control of metal strip, particularly non-ferrous metal strip, during processing. Background technique [0004] Many metalworking processes involve manipulating and processing a continuous strip of metal. Working metal into strips allows for rapid processing of long pieces of metal, but requires that the metal strip remain centered within a certain distance of the desired pass line of the processing equipment. If the strip deviates too far from the equipment's expected pass line, the strip may come into undesired contact with the equipment edge, the strip may not be processed properly (e.g., not heated or cooled unifo...
