El filtro de espuma de circonio cumple las siguientes funciones:<\/strong><\/p>\n

    \n
  1. Purificaci\u00f3n del metal fundido para eliminar los componentes met\u00e1licos y no met\u00e1licos;<\/li>\n
  2. Reducir la cantidad de \u00f3xidos durante la formaci\u00f3n de un flujo turbulento;<\/li>\n
  3. Aumentar la fluidez del metal;<\/li>\n
  4. Eliminaci\u00f3n de inclusiones y defectos met\u00e1licos;<\/li>\n
  5. Mejora de la calidad de la fundici\u00f3n gracias a la mejora de las propiedades mec\u00e1nicas;<\/li>\n
  6. Reducir la generaci\u00f3n de residuos y evitar trabajos adicionales.<\/li>\n<\/ol>\n

    Todos los filtros cer\u00e1micos de espuma se caracterizan por una matriz de malla. Los poros, de forma esf\u00e9rica y del mismo tama\u00f1o y volumen, est\u00e1n conectados entre s\u00ed, formando \u201cventanas\u201d a trav\u00e9s de sus paredes. Gracias a su estructura, con recorridos bastante sinuosos, los poros son capaces de dejar pasar el metal y retener la escoria y otros tipos de contaminantes. En definitiva, esta estructura espec\u00edfica de los filtros basados en PPU demuestra una excelente eficacia en la filtraci\u00f3n de metales en comparaci\u00f3n con los filtros de estructura diferente que se utilizan en la industria de la fundici\u00f3n.<\/p>\n

    \"Filtro<\/p>\n

    Filtro de espuma cer\u00e1mica de circonio<\/a> Es resistente a las altas temperaturas y absorbe sin problemas el metal fundido. Sus caracter\u00edsticas de alta resistencia permiten utilizar estos filtros sin necesidad de instalar rejillas met\u00e1licas de repuesto. El material b\u00e1sico del filtro de espuma cer\u00e1mica de circonio es el ZrO2. La resistencia t\u00e9rmica del filtro de circonio supera los 1760 \u00b0C, y presenta una elevada resistencia mec\u00e1nica y un excelente comportamiento frente a los impactos a altas temperaturas.<\/p>\n

    Entre los distintos tipos de cer\u00e1micas de \u00f3xido met\u00e1lico, la circonia es la que presenta una mayor estabilidad a altas temperaturas. Es la m\u00e1s adecuada para recubrimientos cer\u00e1micos y productos refractarios de alta temperatura. La conductividad t\u00e9rmica de la circonia es la m\u00e1s baja entre los materiales cer\u00e1micos comunes, y su coeficiente de expansi\u00f3n t\u00e9rmica es relativamente similar al de los materiales met\u00e1licos. Su estructura cristalina especial la convierte en un importante material electr\u00f3nico. Sus buenas propiedades mec\u00e1nicas y termof\u00edsicas la convierten en una fase de refuerzo, lo que le confiere excelentes propiedades en los compuestos de matriz met\u00e1lica. Entre las diversas cer\u00e1micas de \u00f3xido met\u00e1lico, el uso de la cer\u00e1mica de circonio solo es superado por el de la cer\u00e1mica de al\u00famina. La cer\u00e1mica de circonio puede alcanzar una alta resistencia y tenacidad mediante el endurecimiento por transformaci\u00f3n de fase.<\/p>","protected":false},"excerpt":{"rendered":"
