El contenido de hidr\u00f3geno gaseoso y las inclusiones s\u00f3lidas en la masa fundida de la aleaci\u00f3n de aluminio son los principales factores que afectan a la calidad de los productos de aleaci\u00f3n de aluminio. La presencia de inclusiones y de hidr\u00f3geno gaseoso rompe la continuidad del metal. Debido a las diferencias en el m\u00f3dulo de elasticidad y el coeficiente de dilataci\u00f3n entre la inclusi\u00f3n y la matriz met\u00e1lica, las aristas vivas de la fase de inclusi\u00f3n son propensas a la concentraci\u00f3n de tensiones y se convierten en una fuente de fractura y corrosi\u00f3n en el material. Es probable que se produzcan diversos defectos durante el procesamiento y la deformaci\u00f3n de los materiales de aleaci\u00f3n de aluminio. Con el fin de mejorar la pureza del fundido de aleaci\u00f3n de aluminio, adem\u00e1s de la fundici\u00f3n del aluminio y la purificaci\u00f3n en el proceso est\u00e1tico, el sistema de purificaci\u00f3n de aleaciones de aluminio<\/a> lo que ocurre fuera del horno es m\u00e1s importante.<\/p>\n

Pureza del fundido de aleaci\u00f3n de aluminio<\/h2>\n

Seg\u00fan los datos obtenidos mediante la medici\u00f3n en l\u00ednea del hidr\u00f3geno y el m\u00e9todo de medici\u00f3n de la escoria, se determina la pureza del aluminio l\u00edquido.<\/p>\n

Pureza de primera clase: l\u00e1mina de aluminio ultrafina, materiales para el cuerpo de latas y otros productos. Se ha determinado que el contenido de hidr\u00f3geno no supera los 0,10 ml\/100 g de aluminio, y que el contenido de escoria no supera los 2 K\/kg.<\/p>\n

Pureza secundaria: sector aeroespacial, trenes de alta velocidad, l\u00e1minas \u00abdoble cero\u00bb, material para cubiertas de latas, cartulina CTP, cartulina para automoci\u00f3n, transporte ferroviario y otros productos de uso importante. Se establece que el contenido de hidr\u00f3geno no debe superar los 0,12 ml\/100 g de aluminio, y que el contenido de escoria no debe superar los 2-5 K\/kg.<\/p>\n

Grado de pureza 3: paneles decorativos para muros cortina y otros productos habituales de aleaci\u00f3n de aluminio (salvo que se especifiquen requisitos especiales). Se establece que el contenido de hidr\u00f3geno no debe superar los 0,2 ml\/100 g de aluminio, y que el contenido de escoria no debe superar los 5-80 K\/kg.<\/p>\n

\"Pureza<\/p>\n

Productos de pureza de primera clase: a\u00f1adir residuos de primera clase y utilizar aditivos de aleaci\u00f3n intermedia o de aluminio. Refinado con gas (gas Ar2 o mezcla de gases) para la protecci\u00f3n del fundente y la aleaci\u00f3n durante la refundici\u00f3n. Configurar desgasificaci\u00f3n rotativa<\/a>\/desgasificaci\u00f3n al vac\u00edo. Utilizando filtro cer\u00e1mico de espuma<\/a> + tipo de tubo.<\/p>\n

Productos de pureza secundaria: a\u00f1adir residuos secundarios y aditivos met\u00e1licos. Refinado con gas (N\u2082) para la protecci\u00f3n del fundente y de la aleaci\u00f3n. Configurar el desgasificado rotativo o el desgasificado al vac\u00edo. Utilizar un filtro cer\u00e1mico de espuma de dos etapas, o un filtro cer\u00e1mico de espuma m\u00e1s un tubo o un lecho profundo para la filtraci\u00f3n.<\/p>\n

Productos de pureza de grado 3: a\u00f1adir residuos de grado 3, restos de aluminio y aditivos met\u00e1licos. Refinado con gas (N\u2082) para flujo<\/a> protecci\u00f3n. Utilizaci\u00f3n de un filtro de espuma cer\u00e1mica.<\/p>","protected":false},"excerpt":{"rendered":"
