The invention relates to a device for hot-dip coating a metal strand (1), especially a steel strip, in which the metal strand (1) is vertically guided through a container (3) accommodating the molten coating metal (2) and through a guide channel (4) disposed upstream thereof. The inventive device comprises at least two inductors (5) disposed at both sides of the metal strand (1) in the area of the guide channel (4) that are used to generate an electromagnetic field for retaining the coating metal (2) in the container (3), and at least one sensor (6, 6′) for detecting the position (s) of the metal strand (1) in the area of the guide channel (4). In order to simplify and render more precise the detection of the position of the metal strand in the guide channel, the sensor for detecting the position of the metal strand (1) consists of two coils (6, 6′) that are disposed, when seen from the direction of conveyance (R) of the metal strand (1), within the height (H0) of the inductors (5) between the inductors (5) and the metal strand (1). The invention further relates to a method for hot-dip coating a metal strand.
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 (H0) 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.
