Filtragem de metal fundido<\/a> A utiliza\u00e7\u00e3o de um filtro de espuma cer\u00e2mica \u00e9 um m\u00e9todo eficaz para remover inclus\u00f5es. O filtro de espuma cer\u00e2mica \u00e9 produzido com poliestireno expandido. O poliestireno \u00e9 expandido por vapor em um molde especialmente projetado para formar um molde de poliestireno. Em seguida, as diversas pastas cer\u00e2micas s\u00e3o vertidas na c\u00e9lula de poliestireno e deixadas para secar ao ar. Ap\u00f3s a opera\u00e7\u00e3o de moldagem, o filtro passa por um processo de sinteriza\u00e7\u00e3o sob diversas condi\u00e7\u00f5es. Com esse novo m\u00e9todo, \u00e9 poss\u00edvel controlar o tamanho do canal do filtro e formar coletores com a configura\u00e7\u00e3o desejada. Foram realizados alguns testes nos filtros produzidos. O teste de choque t\u00e9rmico garante que o filtro possa suportar temperaturas de 1.450 \u00b0C. O teste de absor\u00e7\u00e3o de \u00e1gua mostra que os materiais \u00e0 base de bauxita absorvem mais \u00e1gua do que outros materiais.<\/p>\n![\"\"](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2021\/10\/Refractory-Ceramic-Foam-Filters.jpg\")

O filtro de espuma cer\u00e2mica \u00e9 utilizado como parte integrante do dispositivo de purifica\u00e7\u00e3o do alum\u00ednio fundido, podendo reduzir efetivamente o teor de inclus\u00f5es. O uso de filtros de espuma cer\u00e2mica na produ\u00e7\u00e3o de diversos tipos de ligas de alum\u00ednio permite atingir um n\u00edvel satisfat\u00f3rio de qualidade metal\u00fargica. A sele\u00e7\u00e3o e o uso corretos dos filtros s\u00e3o um pr\u00e9-requisito importante para se obter o melhor efeito de filtragem.<\/p>\n
O filtro de espuma cer\u00e2mica para fundi\u00e7\u00e3o de metais pode reduzir significativamente os defeitos de inclus\u00e3o, refinar os gr\u00e3os cristalinos, melhorar as propriedades mec\u00e2nicas das pe\u00e7as fundidas, melhorar o desempenho de usinagem das pe\u00e7as fundidas, melhorar a qualidade interna e externa das pe\u00e7as fundidas, simplificar o sistema de vazamento, aumentar o rendimento do processo e reduzir a margem de usinagem. Os filtros de espuma cer\u00e2mica melhoraram significativamente a qualidade e a competitividade das pe\u00e7as fundidas de alum\u00ednio e, ao mesmo tempo, aumentaram os lucros das empresas de fundi\u00e7\u00e3o.<\/p>","protected":false},"excerpt":{"rendered":"
