Abstract:
A method for deflecting wire-rod strand moving in a direction at high speed, comprising the steps of:applying a high current, high voltage electric potential to a current conductor disposed in a plane opposite to the wire-rod strand, the current conductor having a first electrode and a second electrode in a direction of movement of the wire-rod strand, said first electrode being electrically connected to said second electrode, the electric connection between the first and second electrodes being realized via a current source, a capacitor and a triggered switching spark gap;inducing a high current flow in a first direction across said current conductor;placing the wire-rod sufficiently close to said current conductor, the wire-rod strand being separated by a space from the first and second electrodes; andproducing between the wire-rod strand and said electrodes an electric arc to close the space between the wire-rod strand and the first and second electrodes and to transmit without contact an electric current to the wire-rod strand so as to induce said high current flow in a second direction opposite to said first direction across the wire-rod strand, thereby generating an electromagnetic force between the wire-rod strand and said current conductor, said force being perpendicular to the plane of the current conductor, thereby deflecting the wire-rod strand away from said current conductor.
