O dispositivo de desgaseifica\u00e7\u00e3o de metais, especialmente projetado e fabricado pela AdTech, \u00e9 utilizado na linha de produ\u00e7\u00e3o de fundi\u00e7\u00e3o. O dispositivo de desgaseifica\u00e7\u00e3o de metais \u00e9 equipado com um rotor de eixo girat\u00f3rio de grafite que pulveriza g\u00e1s inerte, com regula\u00e7\u00e3o cont\u00ednua da velocidade e opera\u00e7\u00e3o normal. O eixo de grafite \u00e9 elevado por um dispositivo hidr\u00e1ulico externo \u00e0 caixa e pode girar livremente em 180\u00b0, o que facilita a manuten\u00e7\u00e3o. O c\u00e2mara de desgaseifica\u00e7\u00e3o<\/a> possui orif\u00edcios adequados para remo\u00e7\u00e3o de esc\u00f3ria e orif\u00edcios de drenagem.<\/p>\n

O dispositivo de desgaseifica\u00e7\u00e3o de metal \u00e9 um sistema automatizado e ecologicamente correto de tratamento de metal fundido, que realiza a desgaseifica\u00e7\u00e3o e a remo\u00e7\u00e3o de esc\u00f3ria de ligas de alum\u00ednio de maneira ecologicamente correta.<\/p>\n

A estrutura da caixa da unidade de desgaseifica\u00e7\u00e3o \u00e9 feita de chapa de a\u00e7o carbono. Entre o inv\u00f3lucro de a\u00e7o e a camada de trabalho, s\u00e3o utilizados produtos de fibra de silicato de alum\u00ednio e placas de silicato de c\u00e1lcio para o isolamento composto, cuja condutividade t\u00e9rmica \u00e9 extremamente baixa, o que cumpre a fun\u00e7\u00e3o de isolar e amortecer a expans\u00e3o da camada de trabalho. Durante o processo de fundi\u00e7\u00e3o, a camada de trabalho do corpo da caixa fica sempre imersa em alum\u00ednio l\u00edquido a alta temperatura; por isso, utiliza-se um material fund\u00edvel especial com alto teor de alum\u00ednio como camada de trabalho do corpo da caixa. O corpo da caixa \u00e9 equipado com entradas e sa\u00eddas de alum\u00ednio, que apresentam boa fluidez.<\/p>\n

O alum\u00ednio fundido flui para dentro do corpo da c\u00e2mara de desgaseifica\u00e7\u00e3o e permanece no revestimento refrat\u00e1rio. A c\u00e2mara possui um aquecedor para manter o alum\u00ednio fundido no estado l\u00edquido. Depois que o g\u00e1s inerte \u00e9 ejetado pelo rotor girat\u00f3rio, ele \u00e9 fragmentado em in\u00fameras pequenas bolhas pela rota\u00e7\u00e3o em alta velocidade do rotor. As pequenas bolhas se difundem e sobem no alum\u00ednio fundido para remover o hidrog\u00eanio. Durante o processo de ascens\u00e3o das pequenas bolhas, devido ao efeito da tens\u00e3o superficial, algumas das inclus\u00f5es s\u00e3o levadas para fora do alum\u00ednio fundido at\u00e9 a superf\u00edcie do l\u00edquido, formando uma esc\u00f3ria para remover as inclus\u00f5es do alum\u00ednio fundido. Ao mesmo tempo, o efeito de agita\u00e7\u00e3o do rotor torna a composi\u00e7\u00e3o da liga no alum\u00ednio fundido mais uniforme.<\/p>","protected":false},"excerpt":{"rendered":"
