Device for hot-dip coating a metal bar

摘要

The invention relates to a device for hot-dip coating a metal bar ( 1 ), particularly a steel strip, in which the metal bar ( 1 ) is vertically directed through a container ( 3 ) receiving the molten coating metal ( 2 ) and a directing channel ( 4 ) that is arranged upstream thereof. Said device comprises at least two inductors ( 5 ) which are disposed on both sides of the metal bar ( 1 ) in the zone of the directing channel ( 4 ) and generate an electromagnetic field for retaining the coating metal ( 2 ) within the container ( 3 ). In order to better control the coating process, the inventive device is characterized by a sealing means ( 7, 7 ') which is arranged above the directing channel ( 4 ) in the bottom area ( 6 ) of the container ( 3 ) and alternatively releases or interrupts the flow of molten coating metal ( 2 ) to the metal bar ( 1 ) and/or the directing channel ( 4 ).
