Abstract

LA INVENCION SE REFIERE A UN METODO SEGUN EL CUAL SE RECUECE LA CHAPA EN ATMOSFERA DE RECOCIDO NO OXIDANTE QUE CONTIENE ENTRE UN 0,005 % Y UN 1 % DE AMONIACO Y A CONTINUACION SE SUMERGE EN UN BAÑO DE GALVANIZACION. ESTE METODO SE APLICA EN PARTICULAR A LOS ACEROS QUE CONTIENEN MAS DE UN 0,2 % DE SILICIO COMO ELEMENTO ADITIVO OXIDABLE. DE ESTE MODO SE MEJORAN LAS PROPIEDADES DE IMPREGNACION DEL ACERO EN EL BAÑO DE GALVANIZACION AL TIEMPO QUE SE CONSERVAN LAS PROPIEDADES MECANICAS Y ELECTRICAS INICIALES DEL ACERO.THE INVENTION REFERS TO A METHOD ACCORDING TO WHICH THE SHEET IS RECOVERED IN A NON-OXIDIZING RECOMMENDED ATMOSPHERE CONTAINING BETWEEN 0.005% AND 1% AMMONIA AND BELOW IS SUBMITTED IN A GALVANIZATION BATH. THIS METHOD IS APPLIED IN PARTICULAR TO STEELS CONTAINING MORE THAN 0.2% SILICON AS OXIDABLE ADDITIVE ELEMENT. IN THIS MODE THE IMPREGNATION PROPERTIES OF STEEL ARE IMPROVED IN THE GALVANIZATION BATHROOM AT THE TIME THAT THE INITIAL MECHANICAL AND ELECTRICAL PROPERTIES OF STEEL ARE PRESERVED.
