El m\u00e9todo de refinado del metal fundido consiste en utilizar fundentes para lograr un refinado eficaz. El proceso de refinado del metal convierte determinadas impurezas u \u00f3xidos en compuestos y los separa del metal fundido mediante vaporizaci\u00f3n, salpicadura o flotaci\u00f3n. En este caso, a medida que avanza el refinado, el nivel de impurezas en el metal fundido se reduce considerablemente. Suministramos fundente de refinado<\/a>, que abarca fundentes, fundentes de desescoriado y fundentes granulados para el refinado de metal fundido.<\/p>\n

Durante el refinado, los componentes vaporizados se condensan parcialmente y se adhieren a la superficie libre de la pared del horno de refinado en forma de escoria. Otras impurezas de la escoria que no se han vaporizado se separan y flotan en la superficie del metal fundido. Cuando se inclina el horno para descargar el metal fundido, el flujo de este arrastra una parte de estos residuos adheridos y flotantes, que vuelven a incorporarse a la masa fundida. Adem\u00e1s, si el material refractario o el revestimiento que recibe el metal fundido no se calienta lo suficiente antes de recibirlo, este puede contaminarse con los componentes gaseosos activos adsorbidos en el revestimiento. La parte del revestimiento reacciona con el metal fundido activado por el refinado, o bien es corro\u00edda por este. El metal fundido puede contaminarse con los productos de la corrosi\u00f3n.<\/p>\n

Para evitar que se produzcan tales adherencias y objetos flotantes, es necesario descargar el metal fundido desde el fondo del recipiente de refinado y dejar parte del metal fundido en el recipiente para impedir que las impurezas flotantes se mezclen de nuevo.<\/p>\n

\"Filtro<\/p>\n

Una vez que el metal fundido se ha descargado del recipiente, un filtro de espuma cer\u00e1mica<\/a> se utiliza para eliminar las inclusiones finas no met\u00e1licas. Dado que estos m\u00e9todos no son eficaces para todos los contaminantes reimportados, deben combinarse para actuar sobre cada una de las sustancias reimportadas mencionadas anteriormente.<\/p>\n

Los filtros de espuma cer\u00e1mica de AdTech utilizan espuma de portiforium de alta calidad y cer\u00e1mica de alta pureza como materia prima, y permiten eliminar de forma eficaz las impurezas s\u00f3lidas no met\u00e1licas del aluminio fundido y las aleaciones de aluminio en su industria de fundici\u00f3n de aluminio. \u00a1El uso de los materiales adecuados para altas temperaturas influir\u00e1 positivamente en su productividad!<\/p>","protected":false},"excerpt":{"rendered":"
