  • Patent number: 10655205
    Abstract: The present invention relates to an apparatus for removing top dross of a plating pot where a snout and an air knife are arranged, the snout being arranged between the front end region and the rear end region of a plating pot. The present invention provides an apparatus for removing top dross of a plating pot, the apparatus comprising: a first wiping means which is mounted on the plating pot and is arranged between the snout and the air knife so as to be movable in the width direction of the plating pot; a second wiping means which is mounted on the plating pot and is rotatably arranged between the air knife and the first wiping means so as to transfer, to the rear end region, the top dross transferred by the first wiping means; and a third wiping means which is mounted on the plating pot and is rotatably arranged between the air knife and the front end region so as to transfer the top dross to the front end region. Thereby, the present invention provides an advantageous effect of effectively removing dross.
