Abstract

Se describe en la presente una chapa delgada de acero galvanizada en bano caliente, sin floreado, y un metodo y dispositivo para fabricarla. La chapa de acero galvanizado en bano caliente se caracteriza porque un cristal de zinc solidificado de la capa galvanizada en bano caliente tiene un diametro de particula de textura cristalina promedio de 10 a 88, y no hay trazas de solidificacion de dendritas tras la observacion bajo un microscopio a una amplificacion de 100x. La chapa de acero galvanizado en bano caliente comprende la inmersion de una chapa de acero en un bano de una solucion para recubrimiento de zinc que contiene 0.13 a 0.3% en peso de aluminio; la limpieza en aire de la chapa de acero para remover un exceso de la solucion de recubrimiento; la aspersion de agua o una solucion acuosa sobre la chapa de acero limpiada en aire, utilizando una temperatura de la chapa de acero en el intervalo de una temperatura de galvanizacion en bano caliente a 419 degree C como una temperatura de inicio de la aspersion, y utilizando una temperatura de la capa de acero en el intervalo de 417 degree C a 415 degree C como una temperatura de terminacion de la aspersion; hacer pasar las gotas de liquido asperjado de agua o la solucion acuosa a traves de un electrodo con carga de alto voltaje tipo malla que esta cargado electricamente con un alto voltaje de -1 a -50 kV; y permitir que las gotas de liquido que pasan por el electrodo se unan a la superficie de la chapa de acero y sirviendo con ello como nucleos de solidificacion del zinc fundido. La chapa de acero galvanizado en bano caliente de la presente invencion presenta superior resistencia a la corrosion, resistencia al ennegrecimiento, resistencia a las manchas de aceite, coeficientes de friccion superficial y apariencia de superficie, y se puede utilizar para diversos materiales como placas internas y externas de carrocerias, aparatos electricos domesticos y materiales de construccion y chapa de acero para pintura.
