Los m\u00e9todos de purificaci\u00f3n y modificaci\u00f3n de la masa fundida pueden influir significativamente en las propiedades de la aleaci\u00f3n, especialmente en la tenacidad y la conductividad el\u00e9ctrica. Investigar y desarrollar diversas tecnolog\u00edas avanzadas de purificaci\u00f3n y modificaci\u00f3n de la masa fundida, centr\u00e1ndose en resolver el problema de la baja calidad metal\u00fargica de los lingotes.<\/p>\n

Con el desarrollo de la industria del autom\u00f3vil, se utilizan cada vez m\u00e1s piezas fundidas de aleaci\u00f3n de aluminio, y los requisitos que deben cumplir estas piezas son cada vez m\u00e1s exigentes. Adem\u00e1s de los requisitos para garantizar la composici\u00f3n qu\u00edmica, las propiedades mec\u00e1nicas y la precisi\u00f3n dimensional, las piezas fundidas de aleaci\u00f3n de aluminio no deben presentar defectos de fundici\u00f3n, como poros de contracci\u00f3n, poros y poros de escoria. La purificaci\u00f3n del aluminio fundido es una de las medidas para garantizar productos de aleaci\u00f3n de aluminio de alta calidad, y tambi\u00e9n es el m\u00e9todo principal para mejorar la calidad general de las aleaciones de aluminio. El efecto del refinado del aluminio fundido tiene una influencia importante en la formaci\u00f3n de poros, cavidades de contracci\u00f3n e inclusiones, y afecta directamente a las propiedades f\u00edsicas y mec\u00e1nicas de las piezas de fundici\u00f3n de aleaci\u00f3n de aluminio. Sin aluminio fundido de alta calidad, por muy avanzado que sea el procesamiento posterior, los defectos siempre estar\u00e1n presentes en el producto una vez que se hayan producido, y resultar\u00e1 dif\u00edcil obtener piezas de fundici\u00f3n de alta calidad. Por lo tanto, debemos prestar atenci\u00f3n al gas y a las inclusiones presentes en el aluminio fundido, y tomar medidas para eliminarlos.<\/p>\n

\"Filtraci\u00f3n<\/p>\n

En la actualidad, los m\u00e9todos de purificaci\u00f3n en estado fundido incluyen: reposo de la masa fundida en el horno + tratamiento con disolvente, tratamiento con gas inerte + cloro, pulverizaci\u00f3n de polvo y tratamiento de refinado. Los m\u00e9todos de purificaci\u00f3n fuera del horno incluyen desgasificaci\u00f3n en l\u00ednea<\/a> tratamiento, CFF (Filtro de espuma cer\u00e1mica<\/a>), m\u00e9todo de filtraci\u00f3n, etc.<\/p>\n

El sistema de purificaci\u00f3n en l\u00ednea de aluminio fundido de nuestra empresa cuenta con un concepto ingenioso y una estructura \u00fanica, y ofrece mejores resultados en la eliminaci\u00f3n de hidr\u00f3geno y escoria. La tasa de eliminaci\u00f3n de hidr\u00f3geno puede alcanzar m\u00e1s del 70%, y permite eliminar el 99% de las inclusiones con un tama\u00f1o de part\u00edcula superior a 20 um. Se trata de la tecnolog\u00eda de refinado de aluminio fundido m\u00e1s avanzada y permite obtener lingotes de alta calidad a gran escala para la producci\u00f3n de chapas gruesas de aleaci\u00f3n de aluminio de alto rendimiento.<\/p>\n

Adem\u00e1s, tambi\u00e9n merecen atenci\u00f3n los m\u00e9todos de adici\u00f3n de oligoelementos y modificadores de Sr, as\u00ed como su interacci\u00f3n con otros elementos en las aleaciones de aluminio. Esto se debe a que influyen en la formaci\u00f3n de compuestos primarios de grano grueso en el lingote, lo que a su vez afecta a su morfolog\u00eda y distribuci\u00f3n en la estructura, y tiene un grave impacto en las propiedades de la aleaci\u00f3n.<\/p>","protected":false},"excerpt":{"rendered":"
