placa filtrante de espuma cer\u00e2mica<\/a> possui uma rede multicamadas e orif\u00edcios de passagem multidimensionais, e os orif\u00edcios est\u00e3o interligados entre si. Durante a filtra\u00e7\u00e3o, o alum\u00ednio fundido transporta inclus\u00f5es e flui ao longo dos canais sinuosos e poros, sendo diretamente interceptado, adsorvido, depositado etc. ao entrar em contato com a estrutura espumosa da placa filtrante. Quando o material fundido flui pelo orif\u00edcio, o canal da placa filtrante \u00e9 curvo; o material fundido que passa pelo canal muda a dire\u00e7\u00e3o do fluxo, e as inclus\u00f5es colidem com a parede do orif\u00edcio e aderem firmemente a ela.<\/p>\n![\"O](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2021\/08\/Best-Ceramic-Foam-Filter.jpg\")
<\/p>\n
Ao projetar o equipamento de filtragem por placas, deve-se basear-se nas especifica\u00e7\u00f5es da placa filtrante de espuma cer\u00e2mica a ser selecionada e, levando em considera\u00e7\u00e3o o desn\u00edvel entre a boca do forno e a placa divis\u00f3ria, \u00e9 necess\u00e1rio garantir que a placa filtrante fique imersa no alum\u00ednio fundido durante a colada da massa fundida. Al\u00e9m disso, deve-se garantir que a instala\u00e7\u00e3o e a desmontagem sejam muito seguras e convenientes, e que o alum\u00ednio l\u00edquido na caixa de filtragem possa ser completamente drenado ap\u00f3s a fundi\u00e7\u00e3o.<\/p>\n
Quanto mais pr\u00f3ximo o equipamento de filtragem por placas estiver da placa divis\u00f3ria, melhor ser\u00e1 o efeito de filtragem. Isso ocorre porque tal disposi\u00e7\u00e3o reduz a dist\u00e2ncia percorrida pelo alum\u00ednio l\u00edquido ap\u00f3s a filtragem, diminuindo assim a regenera\u00e7\u00e3o de \u00f3xidos. O alum\u00ednio fundido sai pela boca do forno, passa pela caixa de filtragem e, em seguida, flui para a placa divis\u00f3ria atrav\u00e9s da calha. Quando o dispositivo de filtragem \u00e9 acionado, a queda antes e depois da filtragem do metal fundido \u00e9 de cerca de 50 mm. Com o prolongamento do tempo de filtragem, as inclus\u00f5es na superf\u00edcie da placa filtrante e na parede do orif\u00edcio aumentam, o fluxo de filtragem diminui e a queda na parte dianteira e traseira aumenta. Ao final da fundi\u00e7\u00e3o, a queda aumenta para 60 a 120 mm. A escolha da placa filtrante de espuma cer\u00e2mica deve basear-se no fluxo do alum\u00ednio fundido. Em segundo lugar, devem ser considerados a limpeza do metal fundido, o maior teor de inclus\u00f5es e a vaz\u00e3o total do metal fundido.<\/p>\n
O efeito de filtragem da placa filtrante \u00e9 garantido principalmente por seu tamanho e porosidade. Quanto maiores forem os poros da placa filtrante, pior ser\u00e1 o efeito de remo\u00e7\u00e3o de esc\u00f3ria. Para pe\u00e7as fundidas de alum\u00ednio com requisitos rigorosos, devem ser selecionadas placas filtrantes com poros pequenos.<\/p>","protected":false},"excerpt":{"rendered":"
