The invention relates to a device for the hot-dip coating of a metal strip (1), more particularly of a steel band, in which the metal strip (1) is guided vertically through a container (3) containing the molten coating—metal (2) and through an upstream guide channel (6), in the vicinity of which, on both sides of the metal strip (1), are arranged at least two inductors (8) for generating an electromagnetic field for holding the coating metal (2) in the container (3), a furnace chamber (9), which contains guide means and has a protective gas atmosphere, being located upstream of the guide channel (6). In order to ensure a good, durable seal between the guide channel (6) and the furnace chamber (9) under the established conditions, the invention proposes that a gas-tight, heat-resistant and flexible seal (13) be arranged between the furnace chamber (9) and the guide channel (6).
A device for hot dip coating a metal strand (1), especially a steel strip, 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 (6) upstream of the coating tank, where an electromagnetic field is generated in the area of the guide channel (6) by means of at least two inductors (8) installed on both sides of the metal strand (1) in order to keep the coating metal (2) in the coating tank (3), and where a furnace chamber (9) that has guide means and is under a protective gas is arranged upstream of the guide channel (6), wherein a gas-tight, heat-resistant, and flexible seal (13) is arranged between the furnace chamber (9) and the guide channel (6) and where the seal (13) comprises a liquid (16) held in a vessel.
