O processo de reciclagem de sucata de alum\u00ednio geralmente passa pelas quatro etapas b\u00e1sicas a seguir:<\/p>\n

Prepara\u00e7\u00e3o de sucata de alum\u00ednio<\/strong>
\nEm primeiro lugar, a triagem preliminar da sucata de alum\u00ednio, como alum\u00ednio puro, liga de alum\u00ednio forjada, liga de alum\u00ednio fundida, materiais mistos, etc. No caso de res\u00edduos de produtos de alum\u00ednio, eles devem ser desmontados para remover o a\u00e7o e outras pe\u00e7as de metais n\u00e3o ferrosos ligadas ao material de alum\u00ednio; em seguida, passam por processos de lavagem, tritura\u00e7\u00e3o, separa\u00e7\u00e3o magn\u00e9tica, secagem e outros, para a produ\u00e7\u00e3o de alum\u00ednio reciclado.<\/p>\n

\"Processo<\/p>\n

Ingredientes<\/strong>
\nDe acordo com a prepara\u00e7\u00e3o e a qualidade dos materiais de sucata de alum\u00ednio, e em conformidade com os requisitos t\u00e9cnicos dos produtos reciclados, selecione os materiais adequados e calcule a quantidade de cada um deles.<\/p>\n

Liga de alum\u00ednio reciclada e deformada<\/strong>
\nA fim de garantir que a composi\u00e7\u00e3o qu\u00edmica do material da liga atenda aos requisitos t\u00e9cnicos e \u00e0s exig\u00eancias do processo de usinagem sob press\u00e3o, deve-se adicionar uma parte de lingotes de alum\u00ednio prim\u00e1rio quando necess\u00e1rio.<\/p>\n

Liga de alum\u00ednio fundido reciclado<\/strong>
\nOs principais equipamentos para a produ\u00e7\u00e3o de alum\u00ednio secund\u00e1rio s\u00e3o o forno de fundi\u00e7\u00e3o e o forno de refino e purifica\u00e7\u00e3o. Nos \u00faltimos anos, a AdTech vem aprimorando o processo de tratamento e produzindo agentes de refino granulados sem s\u00f3dio para resolver problemas de polui\u00e7\u00e3o ambiental, como o uso de N\u2082, Ar, etc., como agentes de refino. A AdTech tamb\u00e9m desenvolveu um sistema on-line equipamento de purifica\u00e7\u00e3o por desgaseifica\u00e7\u00e3o<\/a> para melhorar a desgaseifica\u00e7\u00e3o e remover impurezas, o que permite valorizar a sucata de alum\u00ednio de baixa qualidade e utiliz\u00e1-la na fabrica\u00e7\u00e3o de lingotes de alum\u00ednio secund\u00e1rio para fundi\u00e7\u00e3o, fundi\u00e7\u00e3o sob press\u00e3o, lamina\u00e7\u00e3o e ligas-mestre.<\/p>\n

No processo de reciclagem de sucata de alum\u00ednio, a fundi\u00e7\u00e3o do alum\u00ednio reciclado e o tratamento da massa fundida s\u00e3o os processos-chave para garantir a qualidade da metalurgia do alum\u00ednio reciclado. A modifica\u00e7\u00e3o, o refinamento e a purifica\u00e7\u00e3o do metal fundido de alum\u00ednio podem n\u00e3o apenas alterar a forma do sil\u00edcio na liga de alum\u00ednio-sil\u00edcio e purificar o metal fundido, mas tamb\u00e9m melhorar significativamente o desempenho da liga de alum\u00ednio. Atualmente, o refinamento, a metamorfose e a purifica\u00e7\u00e3o do metal fundido de alum\u00ednio s\u00e3o tratados principalmente com sais de cloreto e fluoreto, como NaCl, NaF, KCl e Na\u2083AlF\u2086, e alguns s\u00e3o tratados com C\u2081\u2082 ou C\u2082C\u2081\u2086. Embora o efeito do refinamento do alum\u00ednio fundido residual com subst\u00e2ncias que cont\u00eam cloro seja melhor, seus subprodutos, como AlCl\u2083, HCl e Cl, causam s\u00e9rios danos ao corpo humano, ao meio ambiente e aos equipamentos.<\/p>","protected":false},"excerpt":{"rendered":"
