Abstract
The paper describes a new in-line technology for complex treatment of secondary aluminium and aluminium alloys which combines metal filtering, alkali removal and degassing operations into a single unit. Process hydrogen removal efficiencies are expressed as a percentage of original hydrogen content. The relationship between melt velocity and filtration efficiency, and height of filter and filtration efficiency were examined. The CTT system showed superior chlorine utilization efficiency compared to other comercialized in-line technologies. The CTT process offers superior secondary metal treatment performance in terms of inclusion removal and comparable hydrogen and alkali removal efficiencies.
