(FR) FILTRE AYANT UNE STRUCTURE MULTICOUCHE POUR FILTRER DES PARTICULES D'IMPURETÉS À PARTIR DE MÉTAL FONDU
Abstract: front page image
(EN)Provided is a filter having a multi-layered structure for removing impurity particles from a molten metal. The filter includes: a plurality of filter layers sequentially disposed along the flow direction of the molten metal in a downward direction and comprising a plurality of pore channels, wherein the filter layers disposed upstream comprise larger pore channels than those of the filter layers disposed downstream.
(FR)L'invention propose un filtre ayant une structure multicouche pour retirer des particules d'impuretés d'un métal fondu. Le filtre comprend : une pluralité de couches de filtration disposées consécutivement le long de l'écoulement du métal fondu dans une direction descendante et comportant une pluralité de canaux poreux, les couches de filtration disposées en amont comportant des canaux poreux plus grands que ceux des couches de filtration disposées en aval.
