Mecanismo de purificaci\u00f3n del filtro cer\u00e1mico de espuma<\/strong><\/p>\n

El filtro cer\u00e1mico de espuma<\/a> puede interceptar eficazmente las inclusiones presentes en el metal l\u00edquido y mejorar la calidad y el rendimiento de la fundici\u00f3n. El estudio del mecanismo de purificaci\u00f3n del filtro cer\u00e1mico de espuma puede proporcionar una base te\u00f3rica para la mejora y la aplicaci\u00f3n de dicho filtro.<\/p>\n

Una vez que el mecanismo de separaci\u00f3n por flotaci\u00f3n coloca el filtro cer\u00e1mico poroso<\/a> En el sistema de colada, la resistencia al flujo del metal aumenta y el metal l\u00edquido se acumula en el sistema de colada, de modo que este desempe\u00f1a la funci\u00f3n de bloqueo de escorias. Al mismo tiempo, el flujo de metal l\u00edquido inyectado desde el canal de colada se estrangula a trav\u00e9s de un filtro, y el metal l\u00edquido permanece brevemente en el canal de colada. La escoria, de baja densidad, flota y se separa, lo que produce el mismo efecto que en el sistema de colada por la parte inferior. Cuando el metal fundido contin\u00faa verti\u00e9ndose a trav\u00e9s del filtro cer\u00e1mico de espuma, por un lado, la escoria de baja densidad flota hacia arriba y, por otro, el v\u00f3rtice se reduce o se elimina de forma eficaz.
\nEl filtro cer\u00e1mico de espuma con mecanismo de \u201ctorta de filtraci\u00f3n\u201d consiste en un canal en zigzag capaz de retener eficazmente la escoria de forma mec\u00e1nica. Muchas inclusiones de tama\u00f1o superior al de los poros del filtro quedan atrapadas en la entrada del mismo. A medida que aumenta el n\u00famero de inclusiones capturadas, se forma una \u201ctorta de filtraci\u00f3n\u201d compuesta por inclusiones de gran tama\u00f1o en la superficie del extremo de entrada del filtro. La \u201ctorta de filtraci\u00f3n\u201d hace que el flujo del fluido sea m\u00e1s fino, de modo que las inclusiones m\u00e1s peque\u00f1as que el tama\u00f1o de la malla del filtro tambi\u00e9n quedan parcialmente retenidas en la \u201ctorta de filtraci\u00f3n\u201d.<\/p>\n

El filtro de mecanismo de adsorci\u00f3n se coloca en el canal transversal o interior de la cavidad del molde, y el proceso de filtraci\u00f3n corresponde a la filtraci\u00f3n profunda. Cuando la primera corriente de l\u00edquido alcanza la superficie del extremo de entrada del filtro, se produce la adsorci\u00f3n entre el flujo de l\u00edquido y la rejilla de espuma y, al mismo tiempo, se produce el fen\u00f3meno de \u201cimpacto\u201d del flujo de l\u00edquido. El propio filtro tambi\u00e9n tiene la funci\u00f3n de bloquear el flujo. Bajo cierta presi\u00f3n, algunas impurezas se lubrican y absorben f\u00e1cilmente debido a la estrecha relaci\u00f3n de \u201ccorrespondencia coherente\u201d entre las inclusiones y las rejillas cer\u00e1micas de espuma s\u00f3lida. Esta adsorci\u00f3n se basa principalmente en la adsorci\u00f3n f\u00edsica de m\u00faltiples capas moleculares sin selecci\u00f3n, en la que las inclusiones se adhieren capa a capa a la malla del filtro hasta que este se obstruye.<\/p>","protected":false},"excerpt":{"rendered":"
