Na fundi\u00e7\u00e3o semicont\u00ednua, leva-se em conta principalmente o fluxo de metal, enquanto na fundi\u00e7\u00e3o cont\u00ednua considera-se principalmente a quantidade total de metal.<\/p>\n<p>O tamanho da placa filtrante de espuma cer\u00e2mica \u00e9 selecionado da seguinte forma: na \u00e1rea efetiva de filtragem, a vaz\u00e3o de metal por cent\u00edmetro quadrado e por minuto deve ser de 70 a 210 g. Quando a vaz\u00e3o de metal filtrado excede esse intervalo, a efici\u00eancia de filtragem e a capacidade de captura de impurezas s\u00e3o drasticamente reduzidas. \u00c0 medida que o tamanho dos poros da placa filtrante \u00e9 reduzido, o tamanho dos res\u00edduos retidos tamb\u00e9m diminui, e a efici\u00eancia da filtragem e da remo\u00e7\u00e3o de impurezas aumenta.<\/p>\n<p>Produtos de ponta, como materiais para enlatados, chapas de impress\u00e3o, folhas ultrafinas, discos de computador e chapas sem revestimento, exigem o uso de placas filtrantes de poros finos. Se a massa fundida estiver limpa, a placa filtrante de poros finos pode ser usada diretamente; se estiver suja, pode-se adicionar uma placa filtrante de poros grossos \u00e0 frente da placa de poros finos para uma filtragem em duas etapas. Esse efeito de filtragem em duas etapas com filtro de espuma cer\u00e2mica \u00e9 mais eficaz.<\/p>\n<p>A placa filtrante de espuma cer\u00e2mica \u00e9 colocada no <a href=\"http:\/\/www.alalloycasting.com\/pt\/cff-filter-box\/\">Caixa de filtro CFF<\/a>, a base da caixa de filtragem \u00e9 quadrada, o tamanho \u00e9 adequado para a placa de filtragem e est\u00e1 inclinada na dire\u00e7\u00e3o da sa\u00edda para impedir que o ar se acumule sob a placa de filtragem. Ambos os lados da placa de filtragem devem estar imersos no alum\u00ednio fundido; caso contr\u00e1rio, \u00e9 f\u00e1cil que se formem e sejam introduzidos \u00f3xidos adicionais. Antes do uso da caixa de filtragem, o revestimento refrat\u00e1rio deve ser cozido a uma temperatura superior a 650 \u2103 para remover toda a umidade e a \u00e1gua de cristaliza\u00e7\u00e3o. A superf\u00edcie inferior da caixa de filtragem deve apresentar uma certa inclina\u00e7\u00e3o, de modo a permitir a secagem do metal e facilitar a limpeza. Manter a bacia de filtragem limpa \u00e9 muito importante para obter uma filtragem eficiente.<\/p>\n<p>O revestimento de veda\u00e7\u00e3o da placa de filtro de espuma cer\u00e2mica \u00e9 um dos requisitos mais importantes para uma filtragem eficaz. Ele tem duas fun\u00e7\u00f5es: o revestimento de veda\u00e7\u00e3o preenche a lacuna entre a placa de filtro e a caixa de filtro e impede que o metal passe por essa lacuna. Fixe a placa de filtro na caixa de filtro para evitar que ela flutue durante o processo de filtragem. Oferecemos materiais para revestimento de veda\u00e7\u00e3o, incluindo <strong>Borda de algod\u00e3o alargada<\/strong>, <strong>Borda de algod\u00e3o com fibra<\/strong>, e <strong>Borda de papel de
