摘要:
Induction heating is used to heat a moving strip (4) of non-ferrous material by causing it to form a short-circuited loop acting as a secondary winding of a transformer (1), the loop passing pulleys (6, 9, 16). The lengths of material which are incoming and outgoing to and from the loop are on the inside and outside of the loop. For the strip on the inside of the loop to connect with the exterior without further contact with the loop, an insulating spacing member is located between the loop and that strip, preferably by maintaining that strip out of the plane of the loop.
