A tecnologia de purifica\u00e7\u00e3o em linha da liga de alum\u00ednio fundida refere-se principalmente ao refinamento da liga de alum\u00ednio fundida fora do forno. O m\u00e9todo tradicional de tratamento no forno vem sendo gradualmente substitu\u00eddo pela purifica\u00e7\u00e3o cont\u00ednua fora do forno. A tecnologia de purifica\u00e7\u00e3o em linha do metal fundido de liga de alum\u00ednio apresenta um efeito bom e est\u00e1vel, permite obter um metal fundido de melhor qualidade e n\u00e3o \u00e9 prejudicial ao meio ambiente, sendo amplamente utilizada em grandes empresas de processamento de alum\u00ednio.<\/p>\n

Nos \u00faltimos anos, tem-se utilizado cada vez mais m\u00e9todos de pulveriza\u00e7\u00e3o de fluxo de refinamento com g\u00e1s inerte para a purifica\u00e7\u00e3o em linha do metal fundido de ligas de alum\u00ednio. Por exemplo, na produ\u00e7\u00e3o de barras redondas de alum\u00ednio para aplica\u00e7\u00f5es el\u00e9tricas de alta qualidade, um dispositivo de purifica\u00e7\u00e3o em linha da massa fundida \u00e9 instalado entre o forno de fus\u00e3o e a concha da linha de produ\u00e7\u00e3o, incluindo filtragem e refino cont\u00ednuo a g\u00e1s. A tecnologia de jato rotativo \u00e9 considerada o m\u00e9todo mais avan\u00e7ado e eficaz para a remo\u00e7\u00e3o de hidrog\u00eanio.<\/p>\n

Quanto menor for o tamanho das bolhas formadas na massa fundida de alum\u00ednio durante a pulveriza\u00e7\u00e3o, maior ser\u00e1 o grau de dispers\u00e3o; e quanto mais lenta for a velocidade de flutua\u00e7\u00e3o, melhor ser\u00e1 o efeito de remo\u00e7\u00e3o de hidrog\u00eanio. Nos \u00faltimos anos, a tecnologia de filtra\u00e7\u00e3o CFF tem se destacado por ser simples, f\u00e1cil de operar, eficaz na remo\u00e7\u00e3o de esc\u00f3ria e de baixo custo. Ela se tornou um m\u00e9todo convencional de purifica\u00e7\u00e3o na ind\u00fastria de processamento de alum\u00ednio.<\/p>\n

\"Sistema<\/p>\n

\u00c9 dif\u00edcil que um \u00fanico m\u00e9todo de refino consiga, ao mesmo tempo, alcan\u00e7ar alta efici\u00eancia na desgaseifica\u00e7\u00e3o e na remo\u00e7\u00e3o de impurezas, e o tratamento de refino combinado tornou-se a principal dire\u00e7\u00e3o de desenvolvimento para a obten\u00e7\u00e3o de alum\u00ednio fundido de alta qualidade. \u00c9 razo\u00e1vel e eficaz adotar um processo de purifica\u00e7\u00e3o combinado para o alum\u00ednio l\u00edquido eletrol\u00edtico utilizado na produ\u00e7\u00e3o de barras redondas de alum\u00ednio para aplica\u00e7\u00f5es el\u00e9tricas, ou seja, o processo de sopro combinado de g\u00e1s e fluxo (refino) + filtro cer\u00e2mico de espuma filtragem de metal fundido<\/a>.<\/p>\n

Selecione adequadamente o dispositivo de desgaseifica\u00e7\u00e3o e a placa filtrante de espuma cer\u00e2mica para garantir a qualidade do nitrog\u00eanio e do agente de refino, al\u00e9m de reduzir o teor de hidrog\u00eanio de 0,10% a 0,13%. Atualmente, o melhor processo \u00e9 o sopro combinado de g\u00e1s e fluxo (refino) + filtra\u00e7\u00e3o por placa filtrante de espuma cer\u00e2mica. O uso de tratamento de purifica\u00e7\u00e3o cont\u00ednua fora do forno \u00e9 a tend\u00eancia de desenvolvimento do processo de purifica\u00e7\u00e3o das empresas de processamento de alum\u00ednio, tanto no pa\u00eds quanto no exterior.<\/p>","protected":false},"excerpt":{"rendered":"
