A unidade rotativa de desgaseifica\u00e7\u00e3o com nitrog\u00eanio proporciona uma remo\u00e7\u00e3o mais completa do hidrog\u00eanio em compara\u00e7\u00e3o com a desgaseifica\u00e7\u00e3o do fluxo. Al\u00e9m disso, o desgaseificador rotativo n\u00e3o utiliza sais nocivos que contenham cloro e fl\u00faor.<\/p>\n

A unidade rotativa de desgaseifica\u00e7\u00e3o com nitrog\u00eanio tamb\u00e9m pode combinar as fun\u00e7\u00f5es de desgaseifica\u00e7\u00e3o e introdu\u00e7\u00e3o de fluxo. Nesse caso, o g\u00e1s inerte serve como suporte para a corrente de granulado. O m\u00e9todo \u00e9 denominado inje\u00e7\u00e3o de fluxo.<\/p>\n

Vantagens da unidade rotativa de desgaseifica\u00e7\u00e3o com nitrog\u00eanio<\/strong><\/p>\n

Alta efici\u00eancia da a\u00e7\u00e3o do fundente devido \u00e0 melhor mistura com a massa fundida;
\nTempo de processamento curto;
\nIntrodu\u00e7\u00e3o do fluxo control\u00e1vel;
\nM\u00e9todo de fluxagem mais ecol\u00f3gico.<\/p>\n

No m\u00e9todo de desgaseifica\u00e7\u00e3o rotativa<\/a>, o nitrog\u00eanio, que \u00e9 inerte ou quimicamente inativo, \u00e9 injetado atrav\u00e9s de um eixo rotativo e de um rotor.<\/p>\n

A energia do eixo girat\u00f3rio provoca a forma\u00e7\u00e3o de um grande n\u00famero de bolhas finas, proporcionando uma rela\u00e7\u00e3o superf\u00edcie\/volume muito elevada. A grande \u00e1rea superficial espec\u00edfica promove a difus\u00e3o r\u00e1pida e eficiente do hidrog\u00eanio nas bolhas de g\u00e1s, o que ajuda a equalizar a atividade do hidrog\u00eanio nas fases l\u00edquida e gasosa.<\/p>\n

Para a desgaseifica\u00e7\u00e3o e filtra\u00e7\u00e3o do alum\u00ednio fundido e de suas ligas. Reduz as bolhas e as impurezas no alum\u00ednio l\u00edquido.<\/p>\n

A unidade de desgaseifica\u00e7\u00e3o em linha para alum\u00ednio de alta pureza adota um projeto do tipo forno, utilizando a c\u00e2mara de processo para realizar a desgaseifica\u00e7\u00e3o no tanque de desgaseifica\u00e7\u00e3o e na c\u00e2mara est\u00e1tica.<\/p>\n

Realize o tratamento internamente utilizando um rotor de desgaseifica\u00e7\u00e3o; quando ocorrer convec\u00e7\u00e3o na c\u00e2mara, certifique-se de que as pequenas bolhas no alum\u00ednio l\u00edquido possam se propagar completamente.<\/p>\n

A \u00e1rea de contato aumenta o volume da bolha e do alum\u00ednio l\u00edquido.<\/p>\n

Prote\u00e7\u00e3o contra est\u00e1tica, flutua\u00e7\u00e3o do n\u00edvel de l\u00edquido em alum\u00ednio, compensa\u00e7\u00e3o de temperatura.<\/p>\n

O gabinete da unidade de desgaseifica\u00e7\u00e3o em linha adotou um projeto herm\u00e9tico, evitando assim a entrada de ar externo e a gera\u00e7\u00e3o de polui\u00e7\u00e3o secund\u00e1ria.<\/p>\n

A efici\u00eancia de desgaseifica\u00e7\u00e3o do equipamento foi significativamente aprimorada.<\/p>\n

A unidade de desgaseifica\u00e7\u00e3o utiliza uma esta\u00e7\u00e3o de trabalho; o m\u00e9todo de alum\u00ednio l\u00edquido em opera\u00e7\u00e3o permite manter a temperatura por meio de aquecimento el\u00e9trico, com um sistema de aquecimento que utiliza aquecedor de imers\u00e3o, de alta efici\u00eancia t\u00e9rmica, com elementos de aquecimento de carboneto de sil\u00edcio e controle de temperatura por sil\u00edcio; a precis\u00e3o do controle de temperatura \u00e9 elevada e a opera\u00e7\u00e3o \u00e9 simples.<\/p>","protected":false},"excerpt":{"rendered":"
