No processo de fundi\u00e7\u00e3o de ligas de alum\u00ednio, \u00e9 inevit\u00e1vel que surjam diversos defeitos devido a uma fundi\u00e7\u00e3o inadequada, e esses defeitos devem ser tratados em tempo h\u00e1bil. No entanto, a escolha da solu\u00e7\u00e3o adequada pode evitar esses defeitos at\u00e9 certo ponto. O que deve ser feito para evitar defeitos na fundi\u00e7\u00e3o de ligas de alum\u00ednio?<\/p>\n

Defeitos na fundi\u00e7\u00e3o de ligas de alum\u00ednio<\/h2>\n

Est\u00f4matos. Para evitar problemas relacionados aos est\u00f4matos, \u00e9 preciso garantir que n\u00e3o haja entrada de ar durante a inje\u00e7\u00e3o. Al\u00e9m disso, o l\u00edquido de liga de alum\u00ednio deve, antes de entrar na cavidade de fundi\u00e7\u00e3o, passar por um processo de filtragem para remover impurezas e bolhas.<\/p>\n

Poros min\u00fasculos. Quando a liga est\u00e1 no estado l\u00edquido, todo o g\u00e1s presente em seu interior deve ser removido. Ao mesmo tempo, \u00e9 necess\u00e1rio garantir que a velocidade de solidifica\u00e7\u00e3o seja aumentada durante o processo, de modo a impedir que o g\u00e1s escape da liga. AdTech sistema de desgaseifica\u00e7\u00e3o online<\/a> e Caixa de filtro CFF<\/a> s\u00e3o instalados entre o forno de fundi\u00e7\u00e3o de alum\u00ednio e a plataforma da fundi\u00e7\u00e3o. O objetivo principal \u00e9 remover o g\u00e1s e outras impurezas do alum\u00ednio l\u00edquido.<\/p>\n

\"Defeitos<\/p>\n

Encolhimento. \u00c9 necess\u00e1rio projetar um sistema de vazamento adequado e definir o local espec\u00edfico do vazamento. Ao mesmo tempo, \u00e9 preciso garantir que o l\u00edquido se solidifique de maneira ordenada, de modo a reduzir a probabilidade de forma\u00e7\u00e3o de buracos de encolhimento.<\/p>\n

Espa\u00e7o vazio. Para garantir a ordem de solidifica\u00e7\u00e3o e as medidas complementares relacionadas, o material do forno deve estar o mais limpo poss\u00edvel, e deve-se colocar um pouco de ferro frio na \u00e1rea vazia.<\/p>\n

Fissuras. Para evitar a ocorr\u00eancia de fissuras, \u00e9 necess\u00e1rio garantir que a sequ\u00eancia de solidifica\u00e7\u00e3o esteja correta. Ao mesmo tempo, para reduzir a tens\u00e3o interna, a temperatura de vazamento deve ser adequadamente selecionada.<\/p>\n

O texto acima explica como evitar defeitos na fundi\u00e7\u00e3o de ligas de alum\u00ednio. Se voc\u00ea deseja evitar problemas decorrentes desses defeitos, \u00e9 fundamental dominar o m\u00e9todo correto de vazamento. Al\u00e9m disso, os compradores devem prestar aten\u00e7\u00e3o especial ao verificar, no momento da compra de pe\u00e7as de liga de alum\u00ednio, se h\u00e1 algum dos defeitos mencionados acima. E, se necess\u00e1rio, devem devolv\u00ea-las \u00e0 f\u00e1brica a tempo para que sejam reparadas.<\/p>","protected":false},"excerpt":{"rendered":"
