Em setores que exigem alta precis\u00e3o, como o aeroespacial, a aus\u00eancia total de falhas e a aus\u00eancia absoluta de inclus\u00f5es no produto final s\u00e3o requisitos b\u00e1sicos. Para atender a essas necessidades b\u00e1sicas, a filtragem do metal fundido \u00e9 a solu\u00e7\u00e3o mais segura, e os filtros de espuma cer\u00e2mica removem a esc\u00f3ria, impedindo que ela chegue ao molde.<\/p>\n

Para obter uma boa pureza do metal fundido, o uso do equipamento adequado e a manuten\u00e7\u00e3o de um bom controle do processo s\u00e3o a melhor maneira de garantir o sucesso.<\/p>\n

A filtragem de metal fundido \u00e9 uma parte importante de todos os setores de manufatura e fundi\u00e7\u00e3o. Diferentes setores utilizam materiais distintos para filtrar seus produtos acabados. Filtros de espuma cer\u00e2mica de alumina<\/a> s\u00e3o utilizados em fundi\u00e7\u00f5es que moldam alum\u00ednio fundido.<\/p>\n

Como todos sabemos, o alum\u00ednio \u00e9 o melhor material e possui diversas aplica\u00e7\u00f5es. As fundi\u00e7\u00f5es ajudam a moldar o alum\u00ednio fundido em diferentes estruturas para aproveitar melhor o metal. No entanto, a menos que se utilizem ferramentas eficientes para filtr\u00e1-lo, o processo ainda fica incompleto. A presen\u00e7a de impurezas e outros produtos indesejados no metal reduzir\u00e1 a qualidade do metal, diminuindo, assim, a qualidade do material fundido a partir dele. O objetivo final da fundi\u00e7\u00e3o \u00e9 obter lucro, e materiais de fundi\u00e7\u00e3o de alta qualidade ajudam a alcan\u00e7ar esse objetivo.<\/p>\n

Experimentos demonstram que, ap\u00f3s o uso de filtros cer\u00e2micos, a fluidez do alum\u00ednio fundido aumenta em cerca de 25-30%; a taxa de rejei\u00e7\u00e3o das pe\u00e7as fundidas \u00e9 reduzida em 85%; a resist\u00eancia das pe\u00e7as fundidas aumenta em 10 a 20%; os defeitos porosos das pe\u00e7as fundidas s\u00e3o significativamente reduzidos; e o desempenho de usinagem das pe\u00e7as fundidas \u00e9 amplamente aprimorado. Como as impurezas s\u00e3o filtradas, os pontos duros na pe\u00e7a fundida tamb\u00e9m s\u00e3o eliminados. Atualmente, os filtros cer\u00e2micos t\u00eam sido utilizados em diversos setores de fundi\u00e7\u00e3o, como o aeroespacial, automotivo, de maquin\u00e1rio etc., para melhorar a confiabilidade e o desempenho das pe\u00e7as fundidas.<\/p>\n
