O agente de refino para fundi\u00e7\u00f5es de alum\u00ednio \u00e9 um dos solventes mais comuns, apresentando-se principalmente na forma de p\u00f3 branco ou gr\u00e2nulos, e \u00e9 preparado a partir de diversos sais inorg\u00e2nicos, de acordo com uma determinada propor\u00e7\u00e3o.<\/p>\n

Ao fundir produtos de alum\u00ednio, adicionar uma quantidade adequada de agente refinador<\/a> pode remover com efic\u00e1cia o hidrog\u00eanio e as esc\u00f3rias de \u00f3xido flutuantes contidas no alum\u00ednio l\u00edquido. Isso se deve principalmente ao fato de que o agente de refino se decomp\u00f5e facilmente em altas temperaturas, especialmente porque o g\u00e1s produzido \u00e9 propenso a rea\u00e7\u00f5es qu\u00edmicas, e a forte capacidade de adsor\u00e7\u00e3o das inclus\u00f5es de esc\u00f3ria permite que o hidrog\u00eanio escape da massa fundida, de modo que pode desempenhar um papel significativo no efeito de limpeza das esc\u00f3rias. \u00c9 uma boa op\u00e7\u00e3o para empresas com altos requisitos para a fundi\u00e7\u00e3o de alum\u00ednio puro.<\/p>\n

O m\u00e9todo de utiliza\u00e7\u00e3o do agente de refino para fundi\u00e7\u00e3o de alum\u00ednio \u00e9 relativamente simples. Polvilhe-o sobre a superf\u00edcie do l\u00edquido, pressione-o rapidamente para dentro do alum\u00ednio fundido, misture bem e deixe repousar para a remo\u00e7\u00e3o da esc\u00f3ria.<\/p>\n

Durante o processo de uso, \u00e9 poss\u00edvel utilizar uma m\u00e1quina de jato; a pulveriza\u00e7\u00e3o com g\u00e1s inerte proporcionar\u00e1 melhores resultados. A dosagem \u00e9 de aproximadamente 0,3% do peso do alum\u00ednio fundido. Se a pureza do alum\u00ednio fundido for relativamente alta, adicione uma quantidade maior de agente refinador.<\/p>\n

\"Agente<\/p>\n

Existem muitos tipos de ligas de alum\u00ednio fundidas fluxos de refino<\/a> utilizados na fundi\u00e7\u00e3o de ligas de alum\u00ednio, que podem ser divididos em duas categorias: agentes de cobertura (fundentes que impedem a oxida\u00e7\u00e3o da massa fundida e a inala\u00e7\u00e3o) e agentes de refino (remo\u00e7\u00e3o de gases e inclus\u00f5es). Agentes de cobertura<\/a> s\u00e3o diferentes dos agentes refinadores.<\/p>\n

Qualquer fluxo utilizado no processo de fundi\u00e7\u00e3o de ligas de alum\u00ednio deve atender \u00e0s seguintes condi\u00e7\u00f5es.<\/p>\n

1. O ponto de fus\u00e3o deve ser inferior \u00e0 temperatura de fus\u00e3o da liga de alum\u00ednio.
\n2. A densidade deve ser menor do que a da liga de alum\u00ednio.
\n3. Ele \u00e9 capaz de adsorver e dissolver as inclus\u00f5es na massa fundida e remover o g\u00e1s presente nela.
\n4. Ele n\u00e3o deve reagir quimicamente com o metal e o revestimento do forno. Caso reaja com o metal, deve produzir apenas g\u00e1s inerte que seja insol\u00favel no metal, e o fundente deve ser insol\u00favel no metal fundido.
\n5. Baixa higroscopicidade e baixa press\u00e3o de evapora\u00e7\u00e3o.
\n6. N\u00e3o deve conter nem produzir impurezas e gases nocivos.
\n7. Deve apresentar viscosidade e fluidez adequadas.
