Alimentaci\u00f3n y desenrollado de materia prima<\/strong><\/h5>\n\n\n\n

Materia prima: bobina de acero laminado en fr\u00edo (CR) con superficie lisa y alta precisi\u00f3n dimensional. Se procede al desenrollado, al corte de los extremos y a la soldadura de las tiras para formar una banda de acero continua que permita una producci\u00f3n ininterrumpida.<\/p>\n\n\n\n

Limpieza de superficies<\/strong><\/h5>\n\n\n\n

Proceso: Lavado alcalino, cepillado, limpieza electrol\u00edtica, aclarado y secado. Elimina por completo el aceite, el polvo de hierro y las impurezas. Una superficie sucia provocar\u00e1 que el recubrimiento de zinc se descascarille y se desprenda.<\/p>\n\n\n\n

Recocido continuo<\/strong><\/h5>\n\n\n\n

La banda de acero se calienta en un horno de recocido a una temperatura de entre 700 y 850 \u2103 en atm\u00f3sfera protectora (N\u2082+H\u2082). Este proceso elimina las tensiones de laminaci\u00f3n en fr\u00edo, mejora la ductilidad y reduce el \u00f3xido superficial hasta obtener hierro puro, con el fin de mejorar la adherencia del recubrimiento de zinc.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
Galvanizado en caliente (proceso principal)<\/strong><\/h5>\n\n\n\n

La banda de acero se sumerge en un crisol de zinc fundido a una temperatura de entre 450 y 460 \u2103, con una pureza del zinc superior al 99,99%. Se produce una reacci\u00f3n metal\u00fargica entre el acero y el zinc que da lugar a una capa de zinc firmemente adherida, en lugar de un simple recubrimiento superficial.<\/p>\n\n\n\n

Soplado con cuchilla de aire y control del espesor del zinc<\/strong><\/h5>\n\n\n\n

Una vez salido de la cuba de zinc, unas cuchillas de nitr\u00f3geno o aire a alta presi\u00f3n eliminan el exceso de zinc fundido. Se controla con precisi\u00f3n el peso del recubrimiento de zinc (Z40 \/ Z80 \/ Z120), obteni\u00e9ndose una superficie uniforme y brillante.<\/p>\n\n\n\n

Enfriamiento, nivelaci\u00f3n y enderezado<\/strong><\/h5>\n\n\n\n

Enfriamiento a temperatura ambiente mediante enfriamiento al aire y enfriamiento r\u00e1pido en agua. El laminado de acabado optimiza la planitud, elimina las l\u00edneas de fluencia y ajusta la rugosidad superficial. El proceso de enderezado garantiza una chapa plana sin deformaciones.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
Postratamiento<\/strong><\/h5>\n\n\n\n

Tratamiento de pasivaci\u00f3n con una soluci\u00f3n sin cromo o con cromato para prevenir la oxidaci\u00f3n blanca y mejorar la resistencia a la corrosi\u00f3n. El tratamiento antihuellas o el recubrimiento de aceite protegen la superficie de los ara\u00f1azos y facilitan los procesos posteriores.<\/p>\n\n\n\n

Bobinado, inspecci\u00f3n y embalaje<\/strong><\/h5>\n\n\n\n

Se corta a la longitud requerida o se rebobina, tras una inspecci\u00f3n exhaustiva del recubrimiento, las diferencias de color y los defectos superficiales. Los procedimientos finales incluyen el pesaje, el embalaje y el almacenamiento en el almac\u00e9n.<\/p>\n\n\n\n
