O filtro de fundi\u00e7\u00e3o de alum\u00ednio destina-se, em particular, \u00e0 filtragem de ligas de alum\u00ednio e outros metais n\u00e3o ferrosos para aplica\u00e7\u00f5es em fundi\u00e7\u00e3o e metalurgia a temperaturas de at\u00e9 1.350 \u00b0C.<\/p>\n

Os filtros de fundi\u00e7\u00e3o de alum\u00ednio podem ser utilizados para filtrar um \u00fanico metal no sistema de canais do cristalizador, mas s\u00e3o projetados para ficarem permanentemente imersos no metal fundido, a fim de filtrar grandes volumes de metal durante as campanhas de fundi\u00e7\u00e3o.<\/p>\n

Os filtros podem ser facilmente instalados em tubos verticais, caixas de filtragem, cubas de filtragem, fornos de distribui\u00e7\u00e3o etc.<\/p>\n

O filtro de fundi\u00e7\u00e3o de alum\u00ednio destina-se \u00e0 filtragem \u00fanica de alum\u00ednio e ligas de alum\u00ednio at\u00e9 uma temperatura de 850 \u00b0C.<\/p>\n

S\u00e3o utilizados exclusivamente para serem colocados no sistema de moldagem, no copo filtrante (cone) feito de materiais isolantes ou em extens\u00f5es exot\u00e9rmicas.<\/p>\n

A baixa densidade aparente, a baixa capacidade t\u00e9rmica e a capacidade de aquecimento r\u00e1pido s\u00e3o as principais vantagens desses filtros.<\/p>\n

Filtro para fundi\u00e7\u00e3o de alum\u00ednio, destinado principalmente \u00e0 filtragem de alum\u00ednio e ligas de alum\u00ednio em oficinas de fundi\u00e7\u00e3o e instala\u00e7\u00f5es de fundi\u00e7\u00e3o.<\/p>\n

Um metal mais puro resulta em pe\u00e7as fundidas de melhor qualidade, menor \u00edndice de rejei\u00e7\u00e3o e menor n\u00famero de imperfei\u00e7\u00f5es, o que contribui para o aumento do lucro.<\/p>\n

O filtro de espuma cer\u00e2mica de Al\u2082O\u2083 acaba de ser desenvolvido nos \u00faltimos anos como um novo tipo de filtro para alum\u00ednio fundido, com o objetivo de reduzir os defeitos de fundi\u00e7\u00e3o.
\nPossui caracter\u00edsticas como baixo peso, alta resist\u00eancia mec\u00e2nica, grande \u00e1rea superficial e alta porosidade.<\/p>\n

Devido \u00e0 sua excelente resist\u00eancia ao contato com o alum\u00ednio fundido e \u00e0 corros\u00e3o, os filtros de cer\u00e2mica espumosa podem remover com efic\u00e1cia as impurezas, reduzir o teor de g\u00e1s no alum\u00ednio l\u00edquido e garantir um fluxo laminar, tornando o metal filtrado significativamente mais puro. Um alum\u00ednio mais puro resulta em pe\u00e7as fundidas de melhor qualidade, menor quantidade de rejeitos e menos defeitos de inclus\u00f5es, o que contribui para o aumento do lucro.<\/p>\n

Fornecedores filtros cer\u00e2micos<\/a>\u00a0A tecnologia de fundi\u00e7\u00e3o (Adtech) reduz os respingos durante a fundi\u00e7\u00e3o, diminui o vazamento das veias durante o vazamento da pe\u00e7a fundida, reduz os defeitos superficiais e, obviamente, aumenta a velocidade de produ\u00e7\u00e3o do produto final.
\nReduzir os prazos de fabrica\u00e7\u00e3o das pe\u00e7as fundidas e os danos \u00e0 l\u00e2mina e \u00e0s ferramentas, al\u00e9m de melhorar a qualidade do acabamento da superf\u00edcie da pe\u00e7a fundida.
\nRefor\u00e7ar as pe\u00e7as fundidas para que resistam \u00e0 press\u00e3o e sejam herm\u00e9ticas, aumentar a resist\u00eancia a longo prazo e melhorar a lisura da superf\u00edcie.
\nRequisitos para o projeto do sistema de pr\u00e9-fundi\u00e7\u00e3o, redu\u00e7\u00e3o do comprimento do canal de fundi\u00e7\u00e3o horizontal e aumento da produtividade da tecnologia de fundi\u00e7\u00e3o.<\/p>\n

Os filtros de fundi\u00e7\u00e3o de alum\u00ednio est\u00e3o dispon\u00edveis em formatos quadrados e em formas geom\u00e9tricas n\u00e3o padronizadas; Dimens\u00f5es de 10 mm a 600 mm e espessura de 10 a 50 mm. Os valores mais comuns de porosidade s\u00e3o: 10 ppi, 15 ppi, 20 ppi, 25 ppi. Porosidades mais elevadas est\u00e3o dispon\u00edveis mediante solicita\u00e7\u00e3o.
