  • Wiping device and hot dip coating apparatus using the same
    Patent number: 9708702
    Abstract: A wiping device which blows a wiping gas toward a steel sheet from a pair of wiping nozzles disposed on both sides of the steel sheet so as to face sheet surfaces of the steel sheet, wherein the steel sheet is interposed between the pair of wiping nozzles and is pulled from a hot dip coating bath, the device includes a suctioning tube, wherein: the suctioning tube is disposed on both sides in a width direction of a section of the steel sheet, the section being positioned between the pair of wiping nozzles, so that the suctioning tube is in parallel to the steel sheet; the suctioning tube has a suctioning port that suctions an air; the suctioning port is disposed to face a side end surface of the steel sheet; a cross-sectional shape of the suctioning tube has the largest dimension thereof along a pulling direction of the steel sheet.
