High Shear De-gassing and De-ironing of an Aluminum Casting Alloy made directly from Aluminum End-of-life Vehicle Scrap

Copyright: © 2021 by the authors.High shear melt conditioning (HSMC) technology was used for degassing and de-ironing of an aluminium alloy recovered from the Zorba cast fraction of the non-ferrous scrap from shredded end-of-life vehicles. The results showed that the recovery of aluminium alloy from the Zorba cast fraction was more than 80%. High shear melt conditioning improved the degassing process during melt treatment in comparison with the adding of degassing tablets. The efficiency of the de-ironing process using HSMC increased by up to 24% after increasing the Mn content to 0.8% in the melt. Adding Mn to Zorba melt enhanced the de-ironing process and eliminated the formation of β-AlFeSi intermetallic particles, which have a detrimental effect on both the me-chanical and corrosion properties of the alloy.Innovate UK (REALITY Project grant number 102797)
