The invention relates to a method for melt dip coating a metal strip ( 1 ), especially a steel strip ( 1 a), which is guided through a coating station ( 4 ). The metal strip ( 1 ) is coated with a coating metal ( 3 ), the metal strip ( 1 ) is centrally maintained in a guide channel ( 8 ) in an electromagnetic sealing field ( 13 ) which seals the guide channel ( 8 ) from below and guides the metal strip ( 1 ) laterally, counter to ferromagnetic attraction, through a corrector field ( 14 ). The sealing field ( 13 ) is embodied as an electromagnetic guiding field ( 10 ), as a blocking field ( 11 ) or as a pump field ( 12 ) in order to select adequate lateral sealing when any particular sealing field ( 13 ) is used. Several corrector fields ( 14 ) are arranged in a distributed manner in a selected configuration, whereby the position and number thereof are determined individually at least according to the various widths of the metal strip ( 1 ). |
