filtragem de alum\u00ednio l\u00edquido<\/a> \u00c9 poss\u00edvel adotar um arranjo paralelo de dois ou mais filtros. Nessas opera\u00e7\u00f5es, os grandes comprimentos envolvidos e o grande fluxo total de metal associado podem exigir que o filtro seja substitu\u00eddo no meio da opera\u00e7\u00e3o. Essa troca pode ser realizada por meio do uso de caixas de filtro, sendo que cada canal cont\u00e9m uma unidade de filtro, um dispositivo que transfere o fluxo de uma para outra. O fluxo ser\u00e1 restrito a um filtro e a uma unidade de filtragem por vez; assim que a coluna de \u00e1gua descer pelo primeiro filtro, ele ser\u00e1 transferido para outro canal e para uma nova unidade de filtragem. Percebe-se que tal programa de altern\u00e2ncia pode fornecer um fluxo constante de metal filtrado \u00e0 esta\u00e7\u00e3o de lingotamento cont\u00ednuo.<\/p>\nTamb\u00e9m \u00e9 poss\u00edvel utilizar filtros de m\u00faltiplos est\u00e1gios, e o metal de alimenta\u00e7\u00e3o pode ser muito vantajoso ou at\u00e9 mesmo necess\u00e1rio quando a qualidade do metal de alimenta\u00e7\u00e3o \u00e9 muito baixa em termos de carga n\u00e3o met\u00e1lica. Essa unidade de m\u00faltiplos est\u00e1gios pode consistir em dois ou mais filtros individuais conectados em s\u00e9rie. Tamb\u00e9m \u00e9 conveniente utilizar um \u00fanico filtro com caracter\u00edsticas de classifica\u00e7\u00e3o cont\u00ednuas ao longo de sua espessura. \u00c9 claro que, nesse caso, o tamanho do filtro deve diminuir gradualmente desde a entrada inicial at\u00e9 a posi\u00e7\u00e3o final de sa\u00edda.<\/p>\n

A placa filtrante \u00e9 um item descart\u00e1vel; portanto, ela deve ser vedada na posi\u00e7\u00e3o correta em seu suporte. O dispositivo \u00e9 f\u00e1cil de montar, desmontar e limpar. \u00c9 altamente recomend\u00e1vel utilizar uma junta de veda\u00e7\u00e3o el\u00e1stica para vedar a placa filtrante \u00e0 sua parte chanfrada. A veda\u00e7\u00e3o do tipo junta garante uma instala\u00e7\u00e3o sem vazamentos e proporciona um meio de separa\u00e7\u00e3o eficaz, o que \u00e9 essencial para facilitar a desmontagem. Al\u00e9m disso, como a junta impede que o metal entre na superf\u00edcie de veda\u00e7\u00e3o do suporte, seu uso simplifica bastante o trabalho de limpeza e prolonga efetivamente a vida \u00fatil da unidade, eliminando o problema da corros\u00e3o do metal. Al\u00e9m disso, devido \u00e0 sua elasticidade, a junta pode fornecer atrito suficiente para fixar o corpo do filtro ao suporte. O dispositivo de veda\u00e7\u00e3o n\u00e3o deve entrar em contato com o metal fundido espec\u00edfico, deve resistir a ataques qu\u00edmicos e possuir resist\u00eancia ao fogo suficiente para suportar altas temperaturas de opera\u00e7\u00e3o.<\/p>","protected":false},"excerpt":{"rendered":"
