El m\u00e9todo de purificaci\u00f3n del aluminio fundido adopta el m\u00e9todo de flotaci\u00f3n por burbujas para tres etapas de refinado, inyectando N\u2082 y un agente de refinado a alta temperatura en el fundido; adem\u00e1s, la purificaci\u00f3n en l\u00ednea fuera del horno utiliza CCl\u2084 y N\u2082, que se pulverizan a trav\u00e9s de un rotor de grafito en rotaci\u00f3n, y la escoria se extrae a tiempo para garantizar la calidad del fundido. Tras una serie de m\u00e9todo de purificaci\u00f3n del aluminio<\/a> Mediante estos tratamientos, el contenido de hidr\u00f3geno en la masa fundida puede controlarse con una precisi\u00f3n de 0,12 ml\/100 g de Al.<\/p>\n

AdTech es una empresa internacional que act\u00faa como pionera constante en el sector, centrada en la I+D y la fabricaci\u00f3n de equipos de desgasificaci\u00f3n y filtrado en l\u00ednea, filtros de espuma cer\u00e1mica, materiales de fundici\u00f3n para \u00abhot-top\u00bb, placas de boquillas, materiales de recubrimiento de reparaci\u00f3n y fundentes. Nuestra unidad de desgasificaci\u00f3n en l\u00ednea incorpora tecnolog\u00eda japonesa y cuenta con un dise\u00f1o estructural adecuado. La eficiencia de limpieza de hidr\u00f3geno se mantiene estable en 60% y alcanza hasta 80%.<\/p>\n

Por lo general, se especifica que el contenido de hidr\u00f3geno en el aluminio fundido de la chapa laminada en caliente no debe superar los 0,15 ml\/100 g. Debido a factores como las materias primas, la humedad o el hecho de que las herramientas no se hayan precalentado, queda una cantidad excesiva de gas en la soluci\u00f3n del aluminio fundido, lo que provoca defectos como microporos, burbujas de aire y canales de aire en la chapa laminada en caliente.<\/p>\n

Las principales causas del exceso de hidr\u00f3geno son:<\/p>\n

(1) Hay humedad en la superficie del material fr\u00edo que se devuelve al horno;
\n(2) La temperatura de fusi\u00f3n es demasiado alta, y el aluminio fundido absorbe f\u00e1cilmente la humedad del aire;
\n(3) Humedad generada al calentar con gas licuado de petr\u00f3leo;
\n(4) El nitr\u00f3geno introducido en la c\u00e1mara de desgasificaci\u00f3n contiene humedad.<\/p>\n

Por estas razones, durante la operaci\u00f3n, se debe prestar atenci\u00f3n al control de la temperatura del aluminio fundido, realizar correctamente la desgasificaci\u00f3n del mismo y evitar en la medida de lo posible el uso de gas licuado para el calentamiento. Al mismo tiempo, se debe controlar estrictamente el proceso de producci\u00f3n de nitr\u00f3geno para que su pureza cumpla con los requisitos.<\/p>","protected":false},"excerpt":{"rendered":"
