Method and devices for induction heating during the passage of a

An inductor, used for the inductive reheating of metallurgical products is of the C-shaped magnetic yoke inductor type designed to straddle the product to be reheated. The free ends of the yoke have magnetic poles facing one another. The yoke comprises two polar legs and two intermediate connecting rods joined to one another at one of their ends and each articulated linked respectively to one polar leg by its other end, with the three joints thus formed having parallel axes. This inductor is designed for use in the reheating of products which can have different thicknesses, in particular, for products in motion, for example, as they are being rolled.

Inductor for the inductive reheating of metallurgical products

The device for inductively reheating the verges of a metallurgical product moving down a production line comprises wound pole inductors with C-shaped magnetic yokes, arranged laterally straddling the path followed by the verges. The two arms of the C are trunnioned to open to a greater or lesser extent, providing a variable air gap, controlled by a cylinder.
