Os agentes de refino para fundi\u00e7\u00e3o s\u00e3o cada vez mais utilizados na ind\u00fastria do alum\u00ednio. O agente de refino \u00e9 capaz de remover os gases e \u00f3xidos do alum\u00ednio fundido, melhorando assim a qualidade das pe\u00e7as fundidas. Atualmente, cada vez mais fabricantes de chapas e folhas de alum\u00ednio utilizam o agente de refino da AdTech.<\/p>\n

Os agentes refinadores para fundi\u00e7\u00e3o podem remover eficazmente as inclus\u00f5es e reduzir o teor de hidrog\u00eanio no ar. O metal puro permite produzir pe\u00e7as fundidas de melhor qualidade, com menos refugo e menos inclus\u00f5es, o que contribui para aumentar os lucros.<\/p>\n

Ap\u00f3s a conclus\u00e3o da fundi\u00e7\u00e3o, h\u00e1 uma grande quantidade de esc\u00f3ria na superf\u00edcie da liga de alum\u00ednio, composta principalmente por inclus\u00f5es de \u00f3xido, como o Al\u2082O\u2083. Essas pequenas inclus\u00f5es s\u00e3o mais pesadas que o alum\u00ednio fundido, mas apresentam uma densidade menor ap\u00f3s a aglomera\u00e7\u00e3o. Elas flutuam na superf\u00edcie e precisam ser removidas. Adicione 0,2%~0,5% removedor de esc\u00f3ria<\/a>, espalhe uniformemente sobre a superf\u00edcie do l\u00edquido na forma de alum\u00ednio e mexa bem.<\/p>\n

\"\"<\/p>\n

Jorge V\u00e1zquez, fundador e diretor-geral da Harbour Intelligence, uma empresa de consultoria especializada em alum\u00ednio, afirmou que os compradores continuam atentos \u00e0s tend\u00eancias do mercado, como, por exemplo, se a R\u00fassia, o segundo maior produtor mundial de alum\u00ednio, manter\u00e1 sua elevada al\u00edquota de imposto de exporta\u00e7\u00e3o at\u00e9 o pr\u00f3ximo ano.<\/p>\n

V\u00e1zquez prev\u00ea que o pre\u00e7o m\u00e9dio do alum\u00ednio em 2022 atingir\u00e1 US$2570 por tonelada, o que representa um aumento de cerca de 9% em rela\u00e7\u00e3o ao pre\u00e7o m\u00e9dio dos contratos futuros de refer\u00eancia de alum\u00ednio negociados em Londres no que vai do ano. Ele tamb\u00e9m espera que o pr\u00eamio de transa\u00e7\u00e3o do CME Group Aluminum Midwest suba para um recorde de 40 centavos\/lb no quarto trimestre, um aumento de 185% em rela\u00e7\u00e3o ao mesmo per\u00edodo do ano passado.<\/p>\n

A Wall Street j\u00e1 havia mencionado que, desde o in\u00edcio da semana passada, o Goldman Sachs e o Citigroup elevaram suas previs\u00f5es para o pre\u00e7o do alum\u00ednio, que deve atingir US$ 3.000 por tonelada no pr\u00f3ximo ano; no entanto, tamb\u00e9m h\u00e1 alertas e opini\u00f5es pessimistas no mercado.<\/p>\n

Al\u00e9m disso, o golpe na Guin\u00e9 gerou preocupa\u00e7\u00f5es quanto \u00e0 interrup\u00e7\u00e3o da cadeia de abastecimento de bauxita no mercado global. Especialistas do setor de bauxita do pa\u00eds afirmaram que \u00e9 improv\u00e1vel que o golpe tenha qualquer impacto significativo no curto prazo sobre as exporta\u00e7\u00f5es. De modo geral, as exporta\u00e7\u00f5es em setembro t\u00eam estado no ponto mais baixo do ciclo. Qualquer governo deseja garantir que as futuras receitas minerais e os investimentos n\u00e3o sejam afetados.<\/p>","protected":false},"excerpt":{"rendered":"
