摘要： The invention relates to a device for hot dip coating a metal bar (1), especially a steel strip, in which the metal bar (1) is directed vertically through a container (3) accommodating the molten coating metal (2) and through a guide channel (4) mounted upstream thereof. The inventive device comprises at least two inductors (5) which are arranged on both sides of the metal bar (1) in the area of the guide channel (4) and generate an electromagnetic field for retaining the coating metal (2) inside the container (3). In order to relax the coating bath, the distance (d) between the walls (6) that delimit the guide channel (4) is not kept constant in a direction (N) extending perpendicular to the surface of the metal strip (1) in the zone (H) of the vertical extension of the guide channel (4), which is located between the bottom side (7) thereof and the bottom area (8) of the container (3).

摘要： A method and an apparatus for an anticipatory thickness control in foil rolling by using characteristic lines stored in a process control computer of the individual manipulated variables (for example, strip tensions, rolling speeds) for various operating points (conditions of operation) or by using an on-line operating physical computing model, also in combination with a monitor control. The method includes the steps of determining the thickness deviations of the foil at the entry side of the roll stand and of compensating the thickness deviations by an anticipatory thickness control. The apparatus includes a thickness measuring device between the running-off reel and the rolling mill or the roll gap of the roll stand. The thickness measuring device is connected to a superordinated process control computer. Following the thickness measuring device is arranged a tensioning unit which serves to change the travel path of the foil strip between the running-off reel and the roll gap. For example, the tensioning unit elongates the travel path.
