Abstract

PROCESO Y DISPOSITIVO PARA EL TRATAMIENTO SUPERFICIAL DE UN PRODUCTO METALICO QUE PERMANECE EN UNA SOLUCION REACTIVA EN PARTICULAR PARA EL DECAPADO O LA GALVANIZACION DE CHAPAS LAMINADAS EN CALIENTE. PROCESO DE DECAPADO O DE GALVANIZACION SEGUN EL CUAL SE IMPRIME A LA CHAPA (1) EN DESLIZAMIENTO EN UN RECIPIENTE LLENO DE ACIDO, VIBRACIONES DE ALTA FRECUENCIA; EL DISPOSITIVO COMPRENDE AL MENOS UN PAR DE ELECTROIMANES (2,3) DISPUESTO UNO ENFRENTE DEL OTRO POR AMBAS PARTES DE LA CHAPA (1) ALIMENTADOS POR CORRIENTES DE IGUAL FRECUENCIA Y EJERCIENDO CADA UNO SOBRE LA CHAPA (1) UNA FUERZA DE ATRACCION PERIODICA, ESTANDO DECALADAS LAS FUERZAS EJERCIDAS POR CADA ELECTROIMAN (2,3) DE PI/2,DE MANERA QUE LA CHAPA (1) VIBRA A UNA FRECUENCIA DEL DOBLE DE LA DE LA CORRIENTE DE ALIMENTACION. LA POTENCIA VIBRATORIA INYECTADA EN LA CHAPA ES SUPERIOR AL UMBRAL DE CAVITACION DE LA SOLUCION REACTIVA CERCA DE LA CHAPA, DE MANERA QUE ESTA CAVITACION ASI COMO LAS VIBRACIONES IMPRESAS A LA CHAPA AGRIETAN LA CAPA DECALAMINA Y FACILITAN SU ATAQUE POR EL ACIDO, LO QUE REDUCE CONSIDERABLEMENTE EL TIEMPO NECESARIO PARA EL DECAPADO DE LA CHAPA.
