Filtro de espuma cer\u00e1mica para fundici\u00f3n de metales<\/strong> Consiste en sumergir una esponja de poliuretano en una pasta cer\u00e1mica, escurrir el exceso, secarla y, por \u00faltimo, sinterizarla a alta temperatura para formar un material cer\u00e1mico poroso tridimensional. Se trata de un tubo con giros y curvas interconectados entre s\u00ed, pero de grosor irregular.
\nEs precisamente esta pared irregular del tubo la que desempe\u00f1a un papel clave a la hora de retener peque\u00f1as inclusiones en el aluminio fundido. Esta estructura tambi\u00e9n aumenta la superficie de contacto entre el aluminio fundido y la parte cer\u00e1mica del Filtros de espuma cer\u00e1mica para fundici\u00f3n<\/a>, lo que aumenta la probabilidad de que se adhieran part\u00edculas de inclusi\u00f3n.<\/p>\n

En la pr\u00e1ctica de la producci\u00f3n mediante fundici\u00f3n<\/strong>, la eficacia de filtraci\u00f3n puede utilizarse para evaluar el efecto purificador del filtro de espuma cer\u00e1mica para fundici\u00f3n de metales en las aleaciones l\u00edquidas de fundici\u00f3n.
\nSe tomaron muestras de la parte superior e inferior de cada pieza fundida procedente de la misma colada o de la misma cuchara de metal fundido para determinar el grado de limpieza de las piezas fundidas filtradas y sin filtrar.
\nUtiliza un microscopio \u00f3ptico y un microscopio electr\u00f3nico de barrido para analizar la zona de ensamblaje de las inclusiones.<\/p>\n

Los defectos por inclusiones de escoria en las piezas fundidas afectan en gran medida a la eficiencia productiva y a los beneficios econ\u00f3micos de la planta de fundici\u00f3n de hierro.<\/strong>
\nLas inclusiones gruesas en la superficie reducen el acabado de la pieza fundida y, en casos graves, provocan que esta se descarte directamente.
\nLos defectos debidos a inclusiones bajo la piel suelen detectarse \u00fanicamente en la fase de procesamiento, en la de montaje o en la de uso real.
\nPor ejemplo, en el taller de mecanizado, la presencia de inclusiones macrosc\u00f3picas o microsc\u00f3picas reducir\u00e1 la maquinabilidad de las piezas fundidas y la vida \u00fatil de las m\u00e1quinas-herramienta.
\nLas inclusiones que se producen durante el montaje o durante el funcionamiento reducir\u00e1n las propiedades mec\u00e1nicas o el rendimiento en servicio de la pieza fundida, por ejemplo, provocando fugas bajo presi\u00f3n.
\nLas piezas fundidas desechadas durante el procesamiento, el montaje o el uso suelen suponer mayores p\u00e9rdidas, ya que E ha realizado m\u00faltiples operaciones previas.<\/p>\n
