Nos \u00faltimos anos, o processamento de alum\u00ednio tem apresentado requisitos de desempenho cada vez mais elevados para produtos ou semiacabados de alum\u00ednio. A qualidade da massa fundida de alum\u00ednio \u00e9 um fator-chave na produ\u00e7\u00e3o de produtos semiacabados ou finais. A AdTech desenvolveu diversos equipamentos com tecnologia que adota v\u00e1rias medidas de purifica\u00e7\u00e3o da massa fundida de ligas de alum\u00ednio para remover gases e inclus\u00f5es. Os requisitos abrangentes de desempenho para massas fundidas de alum\u00ednio concentram-se na maximiza\u00e7\u00e3o da remo\u00e7\u00e3o de hidrog\u00eanio, inclus\u00f5es e metais alcalinos da massa fundida de alum\u00ednio.<\/p>\n

No que diz respeito ao processamento da massa fundida, uma vez que est\u00e1 relacionado ao tipo de liga fundida, ao tipo de instala\u00e7\u00e3o de produ\u00e7\u00e3o (usina de refundi\u00e7\u00e3o, fundi\u00e7\u00e3o, etc.) ou ao tipo de produto fabricado e fundido (lingote em placa, barra para extrus\u00e3o, componente fundido, etc.), Em termos de teor de metais alcalinos e desidrogena\u00e7\u00e3o, de acordo com os diferentes requisitos das empresas de processamento de alum\u00ednio para a purifica\u00e7\u00e3o da fus\u00e3o, utilize:<\/p>\n

Agente refinador granular<\/a><\/strong>: No forno de fus\u00e3o e no forno de manuten\u00e7\u00e3o, utiliza-se o agente refinador granular e o nitrog\u00eanio como g\u00e1s transportador para remover os metais alcalinos e as impurezas do alum\u00ednio fundido no forno.<\/p>\n

\"Fluxo<\/p>\n

Sistema de desgaseifica\u00e7\u00e3o online<\/a><\/strong>: O tratamento da massa fundida \u00e9 realizado na c\u00e2mara de desgaseifica\u00e7\u00e3o para remover o hidrog\u00eanio e as impurezas. Por meio do controle dos metais alcalinos e do hidrog\u00eanio na massa fundida da liga de alum\u00ednio, atende-se \u00e0s necessidades dos usu\u00e1rios de melhorar a qualidade dos lingotes.<\/p>\n

Equipamentos de filtragem on-line<\/a><\/strong>: Instale placas filtrantes de espuma cer\u00e2mica na caixa de filtragem para filtrar ainda mais o alum\u00ednio fundido e remover part\u00edculas finas de impurezas.<\/p>\n

A pureza do alum\u00ednio fundido, ou seja, a redu\u00e7\u00e3o das inclus\u00f5es no alum\u00ednio fundido, \u00e9 um fator muito importante na produ\u00e7\u00e3o de produtos de alta qualidade. As inclus\u00f5es na liga de alum\u00ednio tornam a estrutura da liga descont\u00ednua, reduzem a compacta\u00e7\u00e3o do produto, causam corros\u00e3o e trincas e prejudicam as propriedades mec\u00e2nicas do produto final.<\/p>\n

Com o desenvolvimento gradual das aplica\u00e7\u00f5es industriais do alum\u00ednio, os produtos apresentam requisitos t\u00e9cnicos cada vez mais exigentes para o processamento da massa fundida, e os equipamentos de purifica\u00e7\u00e3o da massa fundida de alum\u00ednio devem estar em conformidade com a pol\u00edtica de prote\u00e7\u00e3o ambiental voltada \u00e0 produ\u00e7\u00e3o de alum\u00ednio sustent\u00e1vel. Somente por meio do aprimoramento cont\u00ednuo dos equipamentos e da tecnologia de purifica\u00e7\u00e3o do alum\u00ednio fundido \u00e9 que poderemos atender aos padr\u00f5es de qualidade mais elevados dos usu\u00e1rios e manter a competitividade sustent\u00e1vel na produ\u00e7\u00e3o de materiais de alto desempenho e alta qualidade. A AdTech est\u00e1 comprometida em aprimorar continuamente a tecnologia de processamento e controle de metal fundido, fornecendo uma linha completa de equipamentos de purifica\u00e7\u00e3o de metal fundido e adotando tecnologia verde para alcan\u00e7ar o desenvolvimento sustent\u00e1vel em termos de prote\u00e7\u00e3o ambiental e efici\u00eancia na ind\u00fastria de processamento de alum\u00ednio.<\/p>","protected":false},"excerpt":{"rendered":"
