A purifica\u00e7\u00e3o por filtra\u00e7\u00e3o CFF tem como objetivo remover as grandes inclus\u00f5es e algumas inclus\u00f5es finas em suspens\u00e3o transportadas no alum\u00ednio fundido atrav\u00e9s do meio filtrante, reduzir o teor de g\u00e1s no alum\u00ednio fundido e remover alguns elementos nocivos presentes nele, al\u00e9m de alterar as propriedades f\u00edsicas e as caracter\u00edsticas de solidifica\u00e7\u00e3o do alum\u00ednio fundido. A purifica\u00e7\u00e3o por filtra\u00e7\u00e3o CFF \u00e9 uma tecnologia destinada a melhorar as propriedades mec\u00e2nicas do alum\u00ednio. Atualmente, a filtra\u00e7\u00e3o CFF (filtro de espuma cer\u00e2mica) \u00e9 a tecnologia mais eficaz e amplamente utilizada no campo da filtra\u00e7\u00e3o e purifica\u00e7\u00e3o.<\/p>\n

O filtro de espuma cer\u00e2mica<\/a> \u00e9 uma estrutura de rede tridimensional cont\u00ednua composta por esqueletos ramificados de cer\u00e2mica fina. O mecanismo de filtragem apresenta tr\u00eas aspectos:<\/p>\n

1. As part\u00edculas de detritos ficam retidas em cada orif\u00edcio da placa filtrante e, em alguns pontos, chegam a se acumular formando um \u201cbolo de filtra\u00e7\u00e3o\u201d, o qual pode reter algumas inclus\u00f5es menores.<\/p>\n

2. Quando o metal fundido passa pela placa filtrante, devido aos canais sinuosos em seu interior, a vaz\u00e3o do metal fundido sofre uma grande varia\u00e7\u00e3o, e algumas part\u00edculas muito pequenas de impurezas se depositam em alguns cantos da placa filtrante.<\/p>\n

3. Como o esqueleto do filtro possui uma superf\u00edcie extensa, e o pr\u00f3prio esqueleto cer\u00e2mico tamb\u00e9m \u00e9 um corpo cer\u00e2mico poroso com poros e microcanais interconectados em seu interior. A superf\u00edcie cer\u00e2mica n\u00e3o \u00e9 molhada pelo metal fundido e possui uma forte capacidade de adsor\u00e7\u00e3o, podendo absorver inclus\u00f5es na liga que n\u00e3o s\u00e3o molhadas pelo metal fundido.<\/p>\n

O efeito combinado dos tr\u00eas mecanismos acima n\u00e3o s\u00f3 permite filtrar part\u00edculas finas de inclus\u00e3o com tamanho de 10 a 20 \u00b5m na massa fundida de alum\u00ednio, como tamb\u00e9m permite filtrar inclus\u00f5es de fluxo l\u00edquido e alguns elementos met\u00e1licos nocivos que s\u00e3o dif\u00edceis de filtrar com meios filtrantes comuns.<\/p>\n

\"Sistema<\/p>\n

Quando a placa filtrante de cer\u00e2mica espumosa est\u00e1 em funcionamento, ela \u00e9 respons\u00e1vel por filtrar o alum\u00ednio fundido, sendo instalada na linha de produ\u00e7\u00e3o de fundi\u00e7\u00e3o semicont\u00ednua ou de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o cont\u00ednuas.<\/p>\n

Portanto, a placa filtrante de cer\u00e2mica espumosa deve apresentar as seguintes caracter\u00edsticas:<\/p>\n

1. Possuir resist\u00eancia mec\u00e2nica suficiente;
\n2. Possui alta resist\u00eancia ao choque t\u00e9rmico e excelente desempenho de limpeza;
\n3. Possuir porosidade e permeabilidade ao metal fundido suficientes;
\n4. Apresenta propriedades de libera\u00e7\u00e3o de gases extremamente baixas;
\n5. Possui alta estabilidade qu\u00edmica.<\/p>\n

No processo de fundi\u00e7\u00e3o, as placas filtrantes de cer\u00e2mica espumada devem ser selecionadas de acordo com diferentes graus de precis\u00e3o de filtragem, diferentes tamanhos de fluxo e vaz\u00f5es. Em circunst\u00e2ncias normais, a placa filtrante de cer\u00e2mica espumada de 30 PPI atende aos requisitos.<\/p>","protected":false},"excerpt":{"rendered":"
