Abstract
An electromagnetic device (1) for stabilizing and minimizing the deformation of a strip (4) made of ferromagnetic material during its feeding in a system for coating the same strip with molten metal, by applying a distribution of force which is continuous in the direction transversal to the strip regardless of the width thereof. The device comprises first electromagnets and second electromagnets mirroring the tirst electromagnets with respect to said theoretical pass-line (50) of said strip (4). Each electromagnet includes a core comprising one pole and one feeding coil wound about the pole. The electromagnetic device comprises a connection element (26) made of ferromagnetic material which connects the cores of the first electromagnets (15, 15′, 15″, 15′″) and a connection element (26′) made of ferromagnetic material which connects the cores of the second electromagnets (16, 16′, 16″, 16′″). The connection elements (26, 26′) mirror the theoretical pass-line (50) of the strip (4).
