Filtro de fundici\u00f3n de espuma de alta porosidad<\/strong><\/p>\n

El filtro de fundici\u00f3n de espuma de alta porosidad se utiliza en la industria metal\u00fargica y en las fundiciones para limpiar el metal fundido de inclusiones no met\u00e1licas y pel\u00edculas de \u00f3xido, lo que contribuye a eliminar muchos defectos, mejorar la calidad del metal, reducir la cantidad de desechos durante la fundici\u00f3n y resolver otros problemas de producci\u00f3n.<\/p>\n

El uso de filtros ofrece:<\/strong>
\nAumentar la uniformidad de la estructura interna del metal.
\nMejora de las propiedades mec\u00e1nicas.
\nEliminaci\u00f3n de imperfecciones metal\u00fargicas (bolsas de gas, porosidad, fugas).
\nMejora de la calidad de la superficie.
\nUna mejora significativa en la maquinabilidad de los productos, lo que reduce el coste de su procesamiento
\nDescenso en el n\u00famero de matrimonios.<\/p>\n

\"Filtro<\/p>\n

Filtro de fundici\u00f3n de espuma de alta porosidad con estructura tridimensional, disponible en diversas formas (circular, ovalada, rectangular, cuadrada), tama\u00f1os, espesores (12-50 mm) y porosidades (8-70 ppi \u2014poros por pulgada lineal\u2014), en funci\u00f3n de las necesidades y los requisitos del cliente.<\/p>\n

Temperatura de aplicaci\u00f3n del filtro: hasta 1700 \u00b0C (en uso de corta duraci\u00f3n, tambi\u00e9n son posibles temperaturas m\u00e1s altas).
\nPara garantizar una eficacia \u00f3ptima de los filtros, es necesario precalentarlos.<\/p>\n

Tres tipos de Filtro de fundici\u00f3n de espuma de alta porosidad<\/a> se ofrecen, y se elaboran sobre la base de:
\n\u00f3xido de aluminio (para filtrar aluminio a temperaturas de hasta 1150 \u00b0C);.
\nDi\u00f3xido de circonio (para el filtrado de acero, as\u00ed como de aleaciones a base de n\u00edquel y cobalto, a temperaturas de hasta 1700 \u00b0C). Aplicaci\u00f3n especial: fundici\u00f3n de magnesio.
\ncarburo de silicio (para el filtrado de hierro d\u00factil y hierro fundido d\u00factil, as\u00ed como de metales no ferrosos a temperaturas de hasta 1420 \u00b0C).<\/p>\n

Para productos especialmente cr\u00edticos, se pueden utilizar filtros d\u00faplex, cuya caracter\u00edstica distintiva es la combinaci\u00f3n de dos tipos de porosidad en un \u00fanico filtro de tama\u00f1o est\u00e1ndar: porosidad PPI 10\/30 con dimensiones a partir de D 100 \u00d7 25 mm.<\/p>\n

Es posible utilizar filtros en distintos puntos del sistema de colada: horizontal o verticalmente a lo largo del recorrido, en la base de la entrada de colada o en el canal de salida.
\nAdem\u00e1s, durante la fundici\u00f3n, gracias a la estructura tridimensional del filtro, el flujo del metal se estabiliza de forma eficaz y el molde se rellena de manera m\u00e1s suave y uniforme. Gracias a ello, se reducen considerablemente tanto la desoxidaci\u00f3n del metal en el molde como la erosi\u00f3n de la arena de moldeo.<\/p>","protected":false},"excerpt":{"rendered":"
