Superior Valorisation of the Aluminium Scraps for Obtaining Complex Aluminium Master Alloys Used in Advanced Refining of the Steels

Abstract

The research about aluminium scraps valorisation to obtain master alloys with reactive elements (Al, Mn, Si) used for special steels refining is presented in this paper. By this way the recycling of aluminium scraps leads to increase the recovery ratio of aluminium as scraps into new materials with added value. These are FeAl, FeMnAl, FeMnSiAl. A new technology for obtaining these materials was proposed. This solution was established to ensure reproducible results, the steadfastness of the chemical composition of alloys, a maximum recovery ratio of elements and low energy consumption.
