发明名称 Method for inline degassing and filtration of molten metal
摘要 The disclosure teaches an improvement in the degassing and filtration of molten metal, especially aluminum, using an apparatus which employs a pair of sequentially placed, removable filter-type plates and at least one fluxing gas inlet positioned therebetween. The first of said filter-type plates is characterized by a plurality of holes which provide a preferential path through which the fluxing gas flows upwardly through the first of said filter plates in countercurrent contact with the melt. Said plate serves to break up said fluxing gas into a fine dispersion to assure its intimate and extensive contact with the melt. Dissolved gases and non-metallic inclusions are thereby abstracted and removed from said melt.
