Apparatus for heating a metallic elongated product

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 the secondary winding of a transformer (1), the loop passing pulleys (6, 9, 16). One of the pulleys (16) has a double groove and the strip (4) passes over one groove (18), around another of the pulleys (19) and back to the other groove (20) of the double grooved pulley (16).
