Patent ID: 8304029

Claim:
Device for hot dip coating a metal strand ( 1 ), in which the metal strand ( 1 ) is passed vertically through a coating tank ( 3 ) that contains the molten coating metal ( 2 ) and through a guide channel ( 4 ) upstream of the coating tank, with at least two inductors ( 5 ) installed on both sides of the metal strand ( 1 ) in the area of the guide channel ( 4 ) for generating an electromagnetic field in order to keep the coating metal ( 2 ) in the coating tank ( 3 ) and with at least one sensor ( 6 , 6 ′) for determining the position (s) of the metal strand ( 1 ) in the area of the guide channel ( 4 ), wherein the sensor for determining the position of the metal strand ( 1 ) consists of two coils ( 6 , 6 ′), which are installed, as viewed in the direction of conveyance (R) of the metal strand ( 1 ), within the height (H 0 ) of the inductors ( 5 ), and between the inductors ( 5 ) and the metal strand ( 1 ), wherein the coils ( 6 , 6 ′) are the same and are designed as wire windings without a core, wherein the coils ( 6 , 6 ′) have one or more windings, and wherein the wire of the coils ( 6 , 6 ′) is made of copper.
