ABSTRACT:
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).
