La filtraci\u00f3n del aluminio fundido es el m\u00e9todo m\u00e1s eficaz y fiable para eliminar las inclusiones no met\u00e1licas del aluminio fundido. Existen muchos tipos de filtraci\u00f3n. El m\u00e1s sencillo es el que se realiza con tela de fibra de vidrio. Los mejores resultados en la filtraci\u00f3n del aluminio fundido se obtienen con tubos filtrantes y placas filtrantes de espuma cer\u00e1mica.<\/p>\n

La principal ventaja del filtro de espuma cer\u00e1mica<\/a> La ventaja de este sistema es que las inclusiones de escoria generadas durante el proceso de inyecci\u00f3n fuera del horno pueden eliminarse eficazmente mediante la placa filtrante, lo que permite eliminar las peque\u00f1as inclusiones de tama\u00f1o microm\u00e9trico presentes en el aluminio l\u00edquido, algo que no es posible con el proceso convencional. Al mismo tiempo, gracias a las peque\u00f1as inclusiones filtradas por la placa filtrante, se reduce el n\u00famero efectivo de n\u00facleos cristalinos en el aluminio l\u00edquido, de modo que el aluminio l\u00edquido se nuclea y crece en condiciones de gran subenfriamiento, lo que acorta el tiempo de solidificaci\u00f3n y refina la estructura. Reducci\u00f3n del contenido de hidr\u00f3geno en el aluminio l\u00edquido. Los \u00e1tomos de hidr\u00f3geno pueden adsorberse en algunas inclusiones de oxidaci\u00f3n, y estas pueden convertirse en el n\u00facleo del crecimiento de burbujas, por lo que el gas presente en las inclusiones puede eliminarse al mismo tiempo; los elementos nocivos (sodio y potasio) del aluminio l\u00edquido pueden eliminarse mediante adsorci\u00f3n. Por lo tanto, en funci\u00f3n de los distintos requisitos de los clientes o de las condiciones ambientales de la planta, la selecci\u00f3n de la placa filtrante adecuada para garantizar la calidad del producto permite controlar eficazmente las inclusiones de escoria.<\/p>\n

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

Los requisitos b\u00e1sicos para los filtros cer\u00e1micos de espuma son:<\/p>\n

    \n
  1. Presenta una resistencia suficiente tanto a temperatura ambiente como a altas temperaturas para evitar da\u00f1os y la ca\u00edda de escoria durante el transporte, la instalaci\u00f3n y el uso.<\/li>\n
  2. Presenta una elevada estabilidad qu\u00edmica, no reacciona con el aluminio fundido en el rango de temperaturas de trabajo y no es perjudicial ni para el aluminio l\u00edquido ni para el medio ambiente.<\/li>\n
  3. Cuenta con una tasa de perforaci\u00f3n y una permeabilidad al aluminio l\u00edquido suficientes para garantizar una filtraci\u00f3n fluida durante la producci\u00f3n.<\/li>\n
  4. Por lo tanto, la placa filtrante debe tener un coeficiente de expansi\u00f3n t\u00e9rmica reducido y no agrietarse al calentarse.<\/li>\n
  5. No es higrosc\u00f3pico, tiene baja densidad y capacidad calor\u00edfica espec\u00edfica, y no es necesario precalentarlo antes de su uso.<\/li>\n<\/ol>","protected":false},"excerpt":{"rendered":"
