A filtragem de alum\u00ednio fundido \u00e9 um m\u00e9todo eficaz para remover inclus\u00f5es do alum\u00ednio fundido. A filtragem do metal fundido por meio de filtro de espuma cer\u00e2mica vem sendo comprovada pelos usu\u00e1rios h\u00e1 muito tempo e pode melhorar o desempenho da produ\u00e7\u00e3o.<\/p>\n

A pel\u00edcula de \u00f3xido \u00e9 constitu\u00edda pelas inclus\u00f5es n\u00e3o met\u00e1licas e pelo g\u00e1s n\u00e3o consumido (principalmente hidrog\u00eanio) que se formam, em sua maior parte, a partir do \u00f3xido de alum\u00ednio no lingote. Portanto, a pel\u00edcula de \u00f3xido \u00e9 um tipo espec\u00edfico de defeito de inclus\u00e3o n\u00e3o met\u00e1lica no lingote, mas difere da inclus\u00e3o de esc\u00f3ria. Geralmente, ele n\u00e3o pode ser detectado durante a inspe\u00e7\u00e3o da amostra de baixa amplia\u00e7\u00e3o e da estrutura de fratura do lingote. Ele s\u00f3 pode ser identificado em amostras preparadas por t\u00e9cnicas especiais (por meio da deforma\u00e7\u00e3o da amostra do lingote).<\/p>\n

A pel\u00edcula de \u00f3xido encontrada na superf\u00edcie de fratura da amostra do processo de lingote pode ser dividida, de maneira geral, em tr\u00eas tipos: um deles \u00e9 uma pel\u00edcula de \u00f3xido em forma de escamas, de cor amarelo-claro, marrom ou marrom-escuro; outro apresenta morfologia superficial semelhante \u00e0 da pel\u00edcula de \u00f3xido em flocos, mas com \u201clantejoulas\u201d brancas brilhantes; e um terceiro tipo consiste em \u201cpequenos pontos brilhantes\u201d redondos ou ovais com brilho branco-prateado.<\/p>\n

Entre elas, a pel\u00edcula de \u00f3xido escamosa \u00e9 uma camada formada por inclus\u00f5es s\u00f3lidas n\u00e3o met\u00e1licas ou bolhas de ar com a superf\u00edcie oxidada. As escamas s\u00e3o camadas formadas por part\u00edculas soltas n\u00e3o compactadas e bolhas de ar, e os pequenos pontos brilhantes s\u00e3o solu\u00e7\u00f5es s\u00f3lidas supersaturadas. Bolhas secund\u00e1rias de hidrog\u00eanio precipitaram-se no corpo.<\/p>\n

\"Tratamento<\/p>\n

Os m\u00e9todos para reduzir e prevenir a forma\u00e7\u00e3o da camada de \u00f3xido nos lingotes de liga de alum\u00ednio s\u00e3o:<\/strong><\/p>\n

Em cada etapa do processo \u2014 desde o armazenamento e a prepara\u00e7\u00e3o da mat\u00e9ria-prima at\u00e9 a fundi\u00e7\u00e3o e a moldagem \u2014, os tr\u00eas aspectos de preven\u00e7\u00e3o, prote\u00e7\u00e3o e refinamento s\u00e3o colocados em pr\u00e1tica, e s\u00e3o tomadas as medidas correspondentes para garantir a pureza do metal.<\/p>\n

Em segundo lugar, o trabalho de preven\u00e7\u00e3o e redu\u00e7\u00e3o da camada de \u00f3xido n\u00e3o deve se concentrar apenas na remo\u00e7\u00e3o das inclus\u00f5es s\u00f3lidas n\u00e3o met\u00e1licas na massa fundida, mas tamb\u00e9m na redu\u00e7\u00e3o, na medida do poss\u00edvel, do teor de hidrog\u00eanio na massa fundida.<\/p>\n

Entre as medidas acima, as mais importantes devem ser os quatro pontos a seguir:<\/strong><\/p>\n
