meio filtrante cer\u00e2mico<\/a>), de modo que o adsorvente e as inclus\u00f5es na massa fundida entrem em contato qu\u00edmico ou f\u00edsico, a fim de realizar o processo de desgaseifica\u00e7\u00e3o e remo\u00e7\u00e3o de esc\u00f3ria. O grau de purifica\u00e7\u00e3o da massa fundida depende das condi\u00e7\u00f5es de contato, ou seja, da \u00e1rea de contato entre a massa fundida e o adsorvente, da dura\u00e7\u00e3o e do estado da superf\u00edcie. O refinamento por adsor\u00e7\u00e3o inclui o refinamento a g\u00e1s, o refinamento com sais de cloreto, o refinamento com fundente e a filtra\u00e7\u00e3o da massa fundida. Atualmente, o refinamento por adsor\u00e7\u00e3o \u00e9 o m\u00e9todo de refinamento mais amplamente utilizado na ind\u00fastria do alum\u00ednio.<\/p>\n![\"Filtros](\"http:\/\/alalloycasting.com\/wp-content\/uploads\/2021\/10\/Aluminum-Casting-Ceramic-Filters.jpg\")

O refinamento sem adsor\u00e7\u00e3o refere-se \u00e0 altera\u00e7\u00e3o do estado de equil\u00edbrio do sistema metal-inclus\u00e3o sem o uso de adsorventes, de modo que as inclus\u00f5es gasosas e s\u00f3lidas n\u00e3o met\u00e1licas sejam removidas da massa fundida de alum\u00ednio. O refinamento por n\u00e3o adsor\u00e7\u00e3o exerce um efeito refinador em todas as massas fundidas de alum\u00ednio. Esse efeito depende das condi\u00e7\u00f5es externas que rompem o equil\u00edbrio e das caracter\u00edsticas de movimento da massa fundida de alum\u00ednio, das inclus\u00f5es e dos gases. O refinamento por n\u00e3o adsor\u00e7\u00e3o inclui o tratamento est\u00e1tico, o tratamento a v\u00e1cuo, o tratamento ultrass\u00f4nico, o tratamento pr\u00e9-solidifica\u00e7\u00e3o e assim por diante.<\/p>\n
H\u00e1 d\u00e9cadas, a tecnologia de refino e purifica\u00e7\u00e3o do alum\u00ednio fundido vem se desenvolvendo no sentido da prote\u00e7\u00e3o ambiental, alta efici\u00eancia, baixo consumo e praticidade. Ao combinar esses m\u00e9todos com um melhor efeito de tratamento, o tratamento composto fora do forno tornou-se uma nova tend\u00eancia de desenvolvimento. Nosso sistema de desgaseifica\u00e7\u00e3o em linha e nosso sistema de filtragem s\u00e3o amplamente utilizados em fundi\u00e7\u00f5es de alum\u00ednio. Eles s\u00e3o capazes de processar uma grande quantidade de alum\u00ednio fundido de uma s\u00f3 vez.<\/p>","protected":false},"excerpt":{"rendered":"
