Abstract

Se proporciona un aparato de galvanización por inmersión en caliente continua que puede inhibir la absorción de rodillos en una zona de homogenización causada por condensación o similar en un tubo de gas humidificado, y con el cual se puede obtener un aspecto de recubrimiento favorable. El aparato de galvanización por inmersión en caliente continua incluye un horno de recocido en el cual una zona de calentamiento, una zona de homogeneización, y una zona de enfriamiento están dispuestas en este orden, y una línea de galvanización por inmersión en caliente adyacente a la zona de enfriamiento. Los gases suministrados a la zona de homogeneización (12) son: gas mixto obtenido al mezclar gas que se humidifica mediante un dispositivo de humidificación (50) y gas que no se ha humidificado mediante el dispositivo de humidificación; y gas seco que no se humidifica mediante el dispositivo de humidificación. El aparato de galvanización por inmersión en caliente continua incluye un dispositivo de drenaje (80) para drenar agua de circulación del dispositivo de humidificación (50) cuando el gas mixto no se suministra a la zona de homogeneización (12).A continuous hot dip galvanizing apparatus is provided that can inhibit the absorption of rollers in a homogenization zone caused by condensation or the like in a humidified gas tube, and with which a favorable coating appearance can be obtained. The continuous hot dip galvanizing apparatus includes an annealing furnace in which a heating zone, a homogenization zone, and a cooling zone are arranged in this order, and a hot dip galvanizing line adjacent to the cooling zone The gases supplied to the homogenization zone (12) are: mixed gas obtained by mixing gas that is humidified by a humidification device (50) and gas that has not been humidified by the humidification device; and dry gas that is not humidified by the humidification device. The continuous hot dip galvanizing apparatus includes a drainage device (80) for draining circulation water from the humidification device (50) when the mixed gas is not supplied to the homogenization zone (12).
