Los filtros de espuma cer\u00e1mica para fundici\u00f3n de metal fundido se utilizan para separar las impurezas s\u00f3lidas finamente divididas que se encuentran en suspensi\u00f3n en el metal fundido. Tambi\u00e9n se ha propuesto que el filtro de espuma cer\u00e1mica pueda utilizarse como medio filtrante, ya que presenta canales tortuosos muy peque\u00f1os capaces de atrapar y retener peque\u00f1as part\u00edculas en suspensi\u00f3n.<\/p>\n

La eliminaci\u00f3n de escorias fuera del horno se realiza principalmente mediante filtros de espuma cer\u00e1mica para fundici\u00f3n de metal fundido, que cuentan con una red multicapa y orificios pasantes multidimensionales, estando dichos orificios conectados entre s\u00ed. Durante el filtrado, el aluminio fundido, que transporta inclusiones, fluye a lo largo de los canales sinuosos y los poros. Al entrar en contacto con la estructura de espuma de la placa filtrante, queda directamente bloqueado, adsorbido, depositado, etc. Cuando el metal fundido fluye por los poros, el canal de la placa filtrante presenta una curvatura; el metal fundido que fluye por el canal cambia de direcci\u00f3n y las inclusiones chocan contra la pared del orificio, donde quedan firmemente adheridas.<\/p>\n

La principal ventaja del sistema de filtrado con espuma cer\u00e1mica<\/a> consiste en que las inclusiones de escoria generadas durante el proceso de transferencia fuera del horno se eliminan de forma eficaz mediante la placa filtrante, as\u00ed como las inclusiones de tama\u00f1o microm\u00e9trico presentes en el aluminio fundido, algo que la tecnolog\u00eda convencional no consigue. Al mismo tiempo, dado que la placa filtrante retiene las inclusiones finas y reduce el n\u00famero efectivo de n\u00facleos cristalinos en el aluminio fundido, este se nuclea y crece en las partes m\u00e1s grandes sobreenfriadas, lo que acorta el tiempo de solidificaci\u00f3n y refina la estructura.<\/p>\n

Reducir el contenido de hidr\u00f3geno en el aluminio fundido. Los \u00e1tomos de hidr\u00f3geno pueden adsorberse en algunas inclusiones oxidadas, y estas pueden convertirse en el n\u00facleo del crecimiento de las burbujas; por ello, las inclusiones se filtran y tambi\u00e9n se elimina el gas que contienen. Mediante la adsorci\u00f3n, se puede eliminar el contenido de elementos nocivos (sodio, potasio) del aluminio fundido. En funci\u00f3n de los distintos requisitos de los clientes o de las condiciones del lugar de trabajo, la selecci\u00f3n de una placa filtrante adecuada para garantizar la calidad del producto permite controlar eficazmente las inclusiones de escoria.<\/p>","protected":false},"excerpt":{"rendered":"
