No processo de produ\u00e7\u00e3o de chapas laminadas a quente de alum\u00ednio e ligas de alum\u00ednio, a vida \u00fatil do bico de fundi\u00e7\u00e3o afeta diretamente a produ\u00e7\u00e3o e a qualidade das chapas laminadas a quente. A vida \u00fatil da ponta de fundi\u00e7\u00e3o e do bico (bico de alimenta\u00e7\u00e3o) tem grande impacto na produ\u00e7\u00e3o de chapas fundidas e laminadas. \u00c9 necess\u00e1rio realizar an\u00e1lises e pesquisas sistem\u00e1ticas sobre o assunto para identificar medidas eficazes que melhorem a vida \u00fatil do bico de alimenta\u00e7\u00e3o.<\/p>\n

Os principais fatores que afetam a vida \u00fatil do bico de alimenta\u00e7\u00e3o de chapas fundidas e laminadas s\u00e3o os seguintes:<\/strong><\/p>\n

\u2460 Estabilidade no fornecimento de alum\u00ednio l\u00edquido.
\n\u2461 A qualidade do material e a qualidade da montagem do bico de alimenta\u00e7\u00e3o.
\n\u2462 Qualidade da fus\u00e3o.
\n\u2463 Comprimento da zona de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o.
\n\u2464 A temperatura da caixa dianteira.
\n\u2465 Velocidade de lamina\u00e7\u00e3o por fundi\u00e7\u00e3o.
\n\u2466 Temperatura e press\u00e3o da \u00e1gua de resfriamento.
\n\u2467 Limpeza da superf\u00edcie do rolo.
\n\u2468 As especifica\u00e7\u00f5es de opera\u00e7\u00e3o e produ\u00e7\u00e3o dos equipamentos s\u00e3o alteradas.<\/p>\n

Embora existam muitos fatores que afetam a vida \u00fatil do bico de fundi\u00e7\u00e3o, eles podem ser resumidos em duas categorias na pr\u00e1tica de produ\u00e7\u00e3o, a saber: a qualidade interna e de montagem do bico de alimenta\u00e7\u00e3o e a sele\u00e7\u00e3o e o controle dos par\u00e2metros do processo.<\/p>\n

\"Dicas<\/p>\n

O material do bocal de alimenta\u00e7\u00e3o<\/a> deve apresentar alto desempenho de processamento, molhabilidade do alum\u00ednio fundido, flexibilidade e condutividade em altas temperaturas, etc. O bico de alimenta\u00e7\u00e3o adota uma estrutura mais adequada, e o ponto-chave \u00e9 como garantir a qualidade da montagem.<\/p>\n

Se a massa fundida contiver g\u00e1s e esc\u00f3ria em excesso, isso afetar\u00e1 o bom funcionamento dos processos de fundi\u00e7\u00e3o e lamina\u00e7\u00e3o e, em casos graves, poder\u00e1 causar a quebra do bico de alimenta\u00e7\u00e3o. O refinamento \u00e9 realizado no forno est\u00e1tico para refinar a massa fundida de alum\u00ednio de acordo com a quantidade utilizada. Ao mesmo tempo, \u00e9 utilizado continuamente no canal de alimenta\u00e7\u00e3o para o refinamento fora do forno, a fim de remover o hidrog\u00eanio. Certifique-se de que o teor de hidrog\u00eanio na massa fundida que entra na caixa frontal esteja abaixo de 0,15 ml\/100 g de Al. Ap\u00f3s o refinamento no forno com agentes de refino<\/a>, deixe repousar para a remo\u00e7\u00e3o das esc\u00f3rias e espalhe uma camada de agente de cobertura.<\/p>\n

A temperatura da caixa de alimenta\u00e7\u00e3o \u00e9 controlada; a temperatura de vazamento e lamina\u00e7\u00e3o \u00e9 monitorada e controlada continuamente; e o gr\u00e1fico de controle \u00e9 utilizado para analisar dinamicamente as varia\u00e7\u00f5es de temperatura, permitindo que os problemas sejam identificados e resolvidos a tempo.<\/p>","protected":false},"excerpt":{"rendered":"
