O dispositivo de filtragem em linha \u00e9 utilizado para a filtragem em linha do alum\u00ednio fundido fora do forno; ele \u00e9 capaz de remover as inclus\u00f5es n\u00e3o met\u00e1licas do alum\u00ednio fundido e melhorar a qualidade do mesmo.<\/p>\n

Estrutura do dispositivo de filtragem online<\/strong><\/p>\n

A caixa do filtro \u00e9 composta por um inv\u00f3lucro de a\u00e7o, um filtro de espuma cer\u00e2mica e um revestimento fund\u00edvel de alto desempenho com alto teor de alum\u00ednio.<\/p>\n

O revestimento interno \u00e9 resistente \u00e0 eros\u00e3o causada pelo alum\u00ednio l\u00edquido, n\u00e3o adere ao alum\u00ednio e n\u00e3o reage quimicamente com ele; a espessura do material mold\u00e1vel \u00e9 \u2265 120 mm, e a espessura da camada de isolamento \u00e9 \u2265 200 mm.<\/p>\n

A placa filtrante \u00e9 aquecida a g\u00e1s, o que garante uma longa vida \u00fatil e facilita a substitui\u00e7\u00e3o.<\/p>\n

A c\u00e2mara de filtragem especialmente projetada permite realizar filtragem em um ou dois est\u00e1gios. Os usu\u00e1rios podem optar por colocar uma ou duas placas de filtragem, de acordo com os requisitos de qualidade do produto final.<\/p>\n

A tampa da caixa do filtro pode ser levantada por um cilindro hidr\u00e1ulico e girada em 180\u00b0, o que \u00e9 pr\u00e1tico e seguro para a substitui\u00e7\u00e3o da placa do filtro.<\/p>\n

O placa de filtro de cer\u00e2mica com espuma<\/a> \u00e9 instalado na caixa de filtro de placas como filtro principal, sendo utilizado principalmente para a purifica\u00e7\u00e3o cont\u00ednua do alum\u00ednio fundido, com um bom efeito de filtragem profunda.<\/p>\n

\"Filtragem<\/p>\n

Como usar equipamentos de filtragem online<\/strong><\/p>\n

1. Sele\u00e7\u00e3o da abertura<\/p>\n

Fundi\u00e7\u00e3o e lamina\u00e7\u00e3o cont\u00ednuas: 40~60 ppi
\nFundi\u00e7\u00e3o por gravidade: 10 a 30 ppi
\nFundi\u00e7\u00e3o semicont\u00ednua: 30~70 ppi
\nAlum\u00ednio ou chapa de alta qualidade: 40 a 90 ppi<\/p>\n

2. Limpe a caixa do filtro;<\/p>\n

3. Coloque cuidadosamente a placa do filtro na caixa do filtro e pressione com a m\u00e3o a junta de veda\u00e7\u00e3o ao redor da placa do filtro para impedir que o alum\u00ednio l\u00edquido vaze;<\/p>\n

4. Pr\u00e9-aque\u00e7a uniformemente a caixa do filtro e a placa do filtro para que atinjam uma temperatura pr\u00f3xima \u00e0 do alum\u00ednio fundido. O pr\u00e9-aquecimento pode ser feito por meio de aquecimento el\u00e9trico ou a g\u00e1s. Normalmente, isso leva cerca de 15 a 30 minutos;<\/p>\n

5. Preste aten\u00e7\u00e3o \u00e0 varia\u00e7\u00e3o da altura manom\u00e9trica do alum\u00ednio durante o vazamento. A altura manom\u00e9trica inicial normal \u00e9 de 100 a 150 mm. Quando o alum\u00ednio l\u00edquido come\u00e7ar a passar, a altura manom\u00e9trica cair\u00e1 para menos de 75 a 100 mm e, em seguida, aumentar\u00e1 gradualmente;<\/p>\n

6. No processo normal de filtragem, evite bater e sacudir a placa do filtro e, ao mesmo tempo, certifique-se de que o canal de fundi\u00e7\u00e3o<\/a> cheio de alum\u00ednio l\u00edquido para evitar perturba\u00e7\u00f5es excessivas no alum\u00ednio fundido;<\/p>\n

7. Ap\u00f3s a filtragem, retire a placa do filtro imediatamente e limpe a caixa do filtro.<\/p>","protected":false},"excerpt":{"rendered":"
