    摘要: A device and a method for stabilizing an elongated metallic strip of a magnetic material when coating the strip with a metallic layer. The strip is transported from the bath in a direction of transport along a predetermined transport path. A wiping device for wiping off superfluous molten metal from the strip applies an air flow in a line across the strip, where the wiping device includes at least one pair of air-knives arranged with one air-knife on each side of the strip. An electromagnetic stabilizing device stabilizes the position of the strip with respect to the predetermined transport path. A sensor detects the position of the strip in relation to the predetermined transport path.
