fluxo de refino<\/a> Deve ser adicionado durante o processo de fus\u00e3o para garantir que os elementos qu\u00edmicos na liga de alum\u00ednio fundida atendam aos requisitos especificados. Normalmente, a propor\u00e7\u00e3o do agente refinador adicionado \u00e9 de 10% a 15% do peso da perda por queima. Por exemplo, devem ser adicionados de 8 kg a 12 kg de agente de refino a cada refino realizado em um forno de fus\u00e3o central de 2T, a fim de garantir que a composi\u00e7\u00e3o qu\u00edmica do alum\u00ednio fundido atenda aos requisitos.<\/p>\n![\"Processo](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2020\/09\/Melting-Process-of-Aluminum-Alloy-1.jpg\")

No processo de fundi\u00e7\u00e3o sob press\u00e3o, os materiais reciclados s\u00e3o geralmente divididos em prim\u00e1rios e secund\u00e1rios, de acordo com o teor de gases impuros. O chamado material reciclado prim\u00e1rio refere-se \u00e0s sobras de fundi\u00e7\u00e3o e aos corpos de produtos rejeitados, que cont\u00eam relativamente menos impurezas e ar, podendo ser diretamente reciclados e fundidos nas empresas de fundi\u00e7\u00e3o sob press\u00e3o. O material secund\u00e1rio refere-se \u00e0 placa de exaust\u00e3o e \u00e0 ranhura de exaust\u00e3o na fundi\u00e7\u00e3o sob press\u00e3o, que s\u00e3o utilizadas principalmente para a exaust\u00e3o e remo\u00e7\u00e3o de impurezas no processo de fundi\u00e7\u00e3o sob press\u00e3o. Ele n\u00e3o pode ser fundido diretamente na empresa de fundi\u00e7\u00e3o sob press\u00e3o; caso contr\u00e1rio, a qualidade do alum\u00ednio l\u00edquido ser\u00e1 seriamente afetada.<\/p>\n
No processo de produ\u00e7\u00e3o real das empresas de fundi\u00e7\u00e3o sob press\u00e3o, quando a propor\u00e7\u00e3o de 8:2 \u00e9 rigorosamente aplicada, ocorre um grande ac\u00famulo de materiais secund\u00e1rios no processo de produ\u00e7\u00e3o, o que aumenta significativamente o custo de produ\u00e7\u00e3o. Portanto, no processo de produ\u00e7\u00e3o real, a empresa pode ajustar essa propor\u00e7\u00e3o por meio de verifica\u00e7\u00f5es experimentais, o que garante a qualidade do alum\u00ednio l\u00edquido, al\u00e9m de reduzir efetivamente o custo de produ\u00e7\u00e3o e melhorar a efici\u00eancia produtiva. No entanto, o princ\u00edpio \u00e9 que a propor\u00e7\u00e3o de materiais reciclados n\u00e3o deve ser superior a 40%. Os experimentos mostram que a composi\u00e7\u00e3o qu\u00edmica do alum\u00ednio l\u00edquido n\u00e3o pode ser efetivamente garantida ap\u00f3s mais de 40% de refino.<\/p>","protected":false},"excerpt":{"rendered":"
