<p>A transverse flux induction heater suitable for heating metal strip (1) moving in the direction of its length has a multiplicity of C-shaped magnetic cores (3, 3') arranged in pairs with their limbs (5) substantially aligned and with one core (3') of each pair positioned below the strip path and the other core (3) of each pair above the strip path. The cores are arranged in at least one row (7, 8) extending transverse of the direction of movement of the strip and the cores in the or each row have an electrical conductor (9, 9') extending transverse to the direction of movement of the strip and passing through the opening between the limbs of each core. Some of the cores in the or each row are displaceable towards and away from the path in order to adjust the heating effected on the metal strip when an alternating current is passed along the conductor. <IMAGE></p> |
