En la actualidad, la mayor\u00eda de las fundiciones de aluminio utilizan equipos de filtrado de placas, que se basan principalmente en filtros de espuma cer\u00e1mica.<\/p>\n

A la hora de dise\u00f1ar y utilizar filtros de espuma cer\u00e1mica para aluminio fundido, se deben tener en cuenta los siguientes aspectos:<\/p>\n

(1) Seg\u00fan los requisitos del producto, seleccione un material filtrante con un tama\u00f1o de poro adecuado. Por lo general, los filtros de espuma cer\u00e1mica de 50 PPI se utilizan para productos extruidos que requieren una alta pureza interna, mientras que los filtros de 30 PPI pueden utilizarse para otros productos generales. Mejorar adecuadamente la precisi\u00f3n de la filtraci\u00f3n reducir\u00e1 la tendencia del lingote a producir cristales gruesos y cristales en forma de pluma.<\/p>\n

(2) Con el fin de mejorar la eficacia de filtrado y la vida \u00fatil del filtro, se debe aumentar al m\u00e1ximo su superficie efectiva de filtrado; es decir, se debe utilizar un filtro de gran tama\u00f1o.<\/p>\n

(3) Al instalar el placa filtrante de espuma cer\u00e1mica<\/a> En la caja del filtro, debe quedar bien ajustada y sin juntas para evitar fugas de aluminio fundido.<\/p>\n

\"\"<\/p>\n

(4) Antes de su uso, el filtro debe precalentarse por completo, y la temperatura de precalentamiento no debe ser inferior a 720 \u2103. En el intervalo entre los tiempos de colada y los de fusi\u00f3n, tambi\u00e9n debe prestarse atenci\u00f3n a la conservaci\u00f3n del calor.<\/p>\n

(5) Para cumplir los requisitos de filtraci\u00f3n fina y prolongar la vida \u00fatil del filtro, lo m\u00e1s recomendable es utilizar tela de vidrio para realizar una filtraci\u00f3n preliminar de la masa fundida antes de pasar por el filtro cer\u00e1mico.<\/p>\n

6) Organizar la producci\u00f3n de forma razonable e intentar evitar cambios frecuentes de aleaciones que dificulten el uso eficaz de los filtros.<\/p>\n

(7) Durante el filtrado, est\u00e1 estrictamente prohibido espolvorear polvo de fundente en el filtro y en la canaleta del horno est\u00e1tico. Durante el proceso de fundici\u00f3n, la altura de presi\u00f3n est\u00e1tica del metal fundido debe aumentar de forma constante para evitar fluctuaciones en el nivel del l\u00edquido, as\u00ed como vibraciones y golpes en el molde. Antes de finalizar la colada, se debe eliminar la escoria de la superficie met\u00e1lica del filtro para evitar la obstrucci\u00f3n de la placa filtrante.<\/p>\n

(8) Evitar la contaminaci\u00f3n secundaria del material fundido filtrado.<\/p>","protected":false},"excerpt":{"rendered":"
