Abstract

Claims (14)

1. A heating system comprising:

a magnetic heating apparatus configured to heat a metal article moving in a downstream direction along a passline through the heating system, wherein the magnetic heating apparatus comprises one or more heaters configured to induce a tailored temperature profile in the metal article, wherein each of the one or more heaters comprises:

a magnetic rotor comprising at least one magnetic source, wherein the magnetic rotor is rotatable about an axis of rotation that is perpendicular to the downstream direction and parallel to a lateral width of the metal article to generate changing magnetic fields through the metal article; and

an auxiliary magnetic heating apparatus configured to heat the metal article moving in the downstream direction, wherein the auxiliary magnetic heating apparatus comprises one or more auxiliary heaters, wherein each of the one or more auxiliary heaters comprises:

an auxiliary magnetic rotor comprising at least one magnetic source and rotatable about an axis of rotation, wherein the auxiliary magnetic rotor is configured to provide localized heating of a sub-area of the metal article less than an entire area across the lateral width of the metal article.

2. The heating system of claim 1 , wherein the auxiliary magnetic heating apparatus is upstream from the magnetic heating apparatus.

3. The heating system of claim 1 , wherein the auxiliary magnetic heating apparatus is downstream from the magnetic heating apparatus.

4. The heating system of claim 1 , wherein the axis of rotation of the auxiliary magnetic rotor of at least one of the one or more auxiliary heaters is perpendicular to the downstream direction and parallel to the lateral width of the metal article.

5. The heating system of claim 1 , wherein the axis of rotation of the auxiliary magnetic rotor of at least one of the one or more auxiliary heaters is perpendicular to the downstream direction and perpendicular to the lateral width of the metal article.

6. The heating system of claim 1 , wherein a length of the auxiliary magnetic rotor of at least one of the one or more auxiliary heaters is less than a length of the magnetic rotor of the one or more heaters.

7. The heating system of claim 1 , wherein the auxiliary magnetic rotor of at least one of the one or more auxiliary heaters is positioned between an edge of the metal article and a centerline of the metal article extending in the downstream direction.

8. The heating system of claim 1 , wherein the one or more auxiliary heaters comprises two auxiliary heaters, and wherein the two auxiliary heaters are symmetrically positioned about a centerline of the metal article extending in the downstream direction.

9. The heating system of claim 1 , wherein a position of the one or more auxiliary heaters relative to the metal article is adjustable.

10. The heating system of claim 9 , wherein the position is a lateral position and a longitudinal position.
