O alum\u00ednio fundido \u00e9 filtrado pelo dispositivo de desgaseifica\u00e7\u00e3o de metal em linha e pelo dispositivo de filtragem, fluindo em seguida para a caixa frontal para fundi\u00e7\u00e3o e lamina\u00e7\u00e3o. O dispositivo de processamento em linha do alum\u00ednio fundido \u00e9 composto principalmente por um dispositivo de desgaseifica\u00e7\u00e3o em linha, um dispositivo de filtragem, um sistema de controle el\u00e9trico, um sistema hidr\u00e1ulico, um gabinete de controle de g\u00e1s refinado e uma calha de conex\u00e3o.<\/p>\n

O dispositivo de desgaseifica\u00e7\u00e3o de metal em linha \u00e9 utilizado para a desgaseifica\u00e7\u00e3o em linha e a remo\u00e7\u00e3o de esc\u00f3ria fora do forno da massa fundida de alum\u00ednio. Ap\u00f3s passar pelo dispositivo de desgaseifica\u00e7\u00e3o em linha, o teor de hidrog\u00eanio na massa fundida de alum\u00ednio pode atender aos requisitos do processo de fundi\u00e7\u00e3o.<\/p>\n

Processo de desgaseifica\u00e7\u00e3o de metais online<\/strong><\/p>\n

Um determinado fluxo de g\u00e1s inerte \u00e9 injetado no alum\u00ednio fundido. Um mecanismo rotativo dispersa o g\u00e1s injetado em min\u00fasculas bolhas, que se difundem uniformemente e sobem no alum\u00ednio fundido, removendo efetivamente o hidrog\u00eanio presente no alum\u00ednio fundido. Ao mesmo tempo, durante o processo de ascens\u00e3o das pequenas bolhas, a tens\u00e3o superficial dessas bolhas tamb\u00e9m pode retirar algumas inclus\u00f5es da massa fundida. Por meio da agita\u00e7\u00e3o causada pelo jato rotativo na massa fundida, os elementos de liga presentes na massa fundida podem ser distribu\u00eddos de maneira mais uniforme.<\/p>\n

Estrutura do dispositivo de desgaseifica\u00e7\u00e3o de metais online<\/strong><\/p>\n

O corpo da caixa do site unidade de desgaseifica\u00e7\u00e3o<\/a> \u00c9 composto por um inv\u00f3lucro de a\u00e7o, um revestimento fund\u00edvel de alto desempenho com alto teor de alum\u00ednio, etc. \u00c9 resistente \u00e0 eros\u00e3o causada pelo alum\u00ednio l\u00edquido, n\u00e3o adere ao alum\u00ednio e n\u00e3o reage quimicamente com ele.<\/p>\n

\u00c9 utilizado o m\u00e9todo de aquecimento por imers\u00e3o. A haste de carboneto de sil\u00edcio \u00e9 colocada em uma manga protetora de material especial, e o conjunto \u00e9 instalado no corpo do forno para aquecer e manter o alum\u00ednio l\u00edquido por convec\u00e7\u00e3o; n\u00e3o h\u00e1 necessidade de drenar o alum\u00ednio l\u00edquido quando a m\u00e1quina \u00e9 desligada.<\/p>\n

O conjunto do rotor de grafite \u00e9 composto por um bocal rotativo e um eixo rotativo fabricados em grafite de alta pureza com propriedades antioxidantes. Sua estrutura especial \u00e9 combinada de forma engenhosa com uma c\u00e2mara de refino especialmente projetada, de modo que as bolhas geradas apresentem melhor dispersibilidade e possam diminuir a velocidade de subida das bolhas, aumentando a probabilidade de que elas retenham hidrog\u00eanio e impurezas, ao mesmo tempo em que se evita a forma\u00e7\u00e3o de v\u00f3rtices na superf\u00edcie da massa fundida, a fim de alcan\u00e7ar uma desgaseifica\u00e7\u00e3o eficiente, remo\u00e7\u00e3o de esc\u00f3ria e efeitos de metais alcalinos.<\/p>\n

O forno de refino \u00e9 dividido em uma c\u00e2mara de refino de dois est\u00e1gios e uma c\u00e2mara de reten\u00e7\u00e3o de calor por meio de uma divis\u00f3ria com excelente condutividade t\u00e9rmica, e cada c\u00e2mara possui uma porta m\u00f3vel pr\u00e1tica para remo\u00e7\u00e3o de esc\u00f3ria, a fim de facilitar a remo\u00e7\u00e3o da esc\u00f3ria a qualquer momento.<\/p>\n

O dispositivo de eleva\u00e7\u00e3o com cilindro hidr\u00e1ulico permite levantar o conjunto do rotor de grafite individualmente e girar 180 graus, o que facilita a manuten\u00e7\u00e3o e a substitui\u00e7\u00e3o do rotor de grafite. O aquecedor e sua manga protetora podem ser levantados como um todo por uma for\u00e7a externa e, em seguida, substitu\u00eddos.<\/p>","protected":false},"excerpt":{"rendered":"
