Os filtros de espuma cer\u00e2mica de alumina para fundi\u00e7\u00e3o s\u00e3o projetados para remover inclus\u00f5es e reduzir a turbul\u00eancia, de modo a proporcionar um fluxo r\u00e1pido e est\u00e1vel do metal fundido, melhorando assim a qualidade das pe\u00e7as fundidas. Possuem excelente efeito de filtragem em todos os tipos de alum\u00ednio e ligas de alum\u00ednio.<\/p>\n

A fundi\u00e7\u00e3o filtro cer\u00e2mico de espuma de alumina<\/a> possui uma estrutura em malha, apresenta certa resist\u00eancia e \u00e9 capaz de suportar o impacto da diferen\u00e7a de press\u00e3o entre a superf\u00edcie do metal l\u00edquido e o fluxo do metal. Gra\u00e7as \u00e0 estrutura precisa desse material, \u00e0 qualidade uniforme, \u00e0 grande \u00e1rea de superf\u00edcie e ao excelente efeito de filtragem.<\/p>\n

As inclus\u00f5es nas pe\u00e7as fundidas s\u00e3o a principal causa de defeitos de fundi\u00e7\u00e3o. Esses defeitos afetam o acabamento superficial, as propriedades mec\u00e2nicas e as propriedades de usinagem das pe\u00e7as fundidas, al\u00e9m de aumentar a taxa de rejei\u00e7\u00e3o.<\/p>\n

Existem muitas fontes de impurezas no alum\u00ednio fundido. Por um lado, durante o processo de fundi\u00e7\u00e3o, o alum\u00ednio fica exposto \u00e0 atmosfera dentro do forno, no estado fundido ou semifundido, o que faz com que se oxide facilmente, reaja com o vapor de \u00e1gua e absorva hidrog\u00eanio, al\u00e9m de formar facilmente diversas formas de res\u00edduos n\u00e3o fund\u00edveis. Esc\u00f3ria met\u00e1lica (como fragmentos do revestimento do forno, cloretos, carbonetos no fundente etc.) e part\u00edculas intermet\u00e1licas grossas.<\/p>\n

\"\"<\/p>\n

Filtro de cer\u00e2mica moldado<\/a> \u00c9 muito importante para a qualidade do alum\u00ednio fundido, o que afeta significativamente o desempenho do processamento subsequente e a qualidade do produto final. Portanto, todos os pa\u00edses do mundo atribuem grande import\u00e2ncia \u00e0 purifica\u00e7\u00e3o do alum\u00ednio fundido.<\/p>\n

A AdTech tem se dedicado \u00e0 pesquisa e desenvolvimento, produ\u00e7\u00e3o e vendas de filtros de espuma cer\u00e2mica de alumina (CFF) para filtragem de liga de alum\u00ednio<\/a>.<\/p>\n

Vantagens da filtra\u00e7\u00e3o por fundi\u00e7\u00e3o com filtro de espuma cer\u00e2mica de alumina:<\/p>\n

1. Adotar o princ\u00edpio da adsor\u00e7\u00e3o, que permite remover com efic\u00e1cia grandes inclus\u00f5es do alum\u00ednio fundido e adsorver com efic\u00e1cia pequenas inclus\u00f5es;
\n2. Aus\u00eancia de queda de esc\u00f3ria, reduzindo efetivamente a polui\u00e7\u00e3o do alum\u00ednio fundido;
\n3. Boa resist\u00eancia ao choque t\u00e9rmico e maior resist\u00eancia \u00e0 corros\u00e3o por metal fundido;
\n4. Produ\u00e7\u00e3o em linha de montagem autom\u00e1tica, tr\u00eas procedimentos de calibra\u00e7\u00e3o, dimens\u00f5es precisas, mais compat\u00edveis com a caixa do filtro;
\n5. Melhorar a qualidade da superf\u00edcie, melhorar o desempenho do produto e melhorar a microestrutura.<\/p>","protected":false},"excerpt":{"rendered":"
