Os filtros de espuma cer\u00e2mica de alumina da AdTech podem ser fabricados por meio de procedimentos espec\u00edficos e apresentam poros especiais semelhantes aos de uma espuma na estrutura \u00f3ssea (denominados \u201ccanais tridimensionais interconectados\u201d) e in\u00fameros orif\u00edcios que s\u00f3 podem ser observados com um microsc\u00f3pio de alta amplia\u00e7\u00e3o.<\/p>\n

Os filtros de espuma cer\u00e2mica de alumina da AdTech s\u00e3o projetados para filtrar alum\u00ednio e ligas de alum\u00ednio. Apresentam excelente estabilidade e resist\u00eancia ao choque t\u00e9rmico. A complexidade dos filtros n\u00e3o \u00e9 prejudicada durante o processo de fundi\u00e7\u00e3o.<\/p>\n

Com excelente resist\u00eancia ao ataque corrosivo e \u00e0 corros\u00e3o do alum\u00ednio fundido, eles podem remover inclus\u00f5es de forma eficaz, reduzir o g\u00e1s arrastado e proporcionar um fluxo laminar.<\/p>\n

Um metal mais puro resulta em pe\u00e7as fundidas de melhor qualidade, menos refugo e menos defeitos de inclus\u00e3o, contribuindo para aumentar o lucro l\u00edquido.<\/p>\n

Filtros de espuma cer\u00e2mica para fundi\u00e7\u00e3o de alum\u00ednio<\/a> geralmente s\u00e3o aplicados colocando-os em um recipiente filtrante.<\/p>\n

\"Filtros<\/p>\n

Filtro de espuma cer\u00e2mica de alumina<\/a> \u00c9 importante pr\u00e9-aquecer o filtro e a cuba antes do uso. Durante o pr\u00e9-aquecimento, a taxa de aquecimento e a distribui\u00e7\u00e3o da temperatura devem ser monitoradas. Isso minimiza o choque t\u00e9rmico e as tens\u00f5es nos filtros e nos refrat\u00e1rios da cuba do filtro.<\/p>\n

Atualmente, a fundi\u00e7\u00e3o de alum\u00ednio com o uso de filtros de espuma cer\u00e2mica \u00e9 cada vez mais comum na ind\u00fastria do alum\u00ednio. Trata-se de filtros especiais fabricados com materiais como carboneto de sil\u00edcio e alumina, que lhes conferem estabilidade estrutural e resist\u00eancia ao choque t\u00e9rmico.<\/p>\n

O filtro de espuma cer\u00e2mica \u00e9 capaz de remover \u00f3xidos da superf\u00edcie do alum\u00ednio e, assim, melhorar a qualidade da fundi\u00e7\u00e3o. Atualmente, cada vez mais fabricantes de chapas e folhas de alum\u00ednio est\u00e3o utilizando os filtros da AdTech.<\/p>\n

Ap\u00f3s passar pelo filtro CFF da AdTech, as impurezas, bem como as subst\u00e2ncias gasosas presentes no metal l\u00edquido ou fundido, podem entrar nos moldes. Isso proporcionar\u00e1 uma pe\u00e7a fundida mais limpa. Quando o metal passa pelo filtro de espuma cer\u00e2mica de zirc\u00f4nia, o filtro consegue remover com mais efic\u00e1cia as impurezas, bem como os gases e l\u00edquidos. Isso se deve ao fato de que o molde do filtro extrudado possui aberturas de malha de formato regular, pelas quais o metal fundido pode passar facilmente.<\/p>","protected":false},"excerpt":{"rendered":"
