Production of Secondary Aluminium Alloys as Part of Strategies of Sustainable and Eco-Oriented Development of Ukrainian Industry
摘要
Two approaches to aluminium production have been explored: the electrolytic extraction of aluminium from aluminium oxide and the manufacturing of secondary aluminium from waste materials and scrap. The results indicate that the second method reduces power consumption and decreases harmful emissions into the environment but requires technological improvements for enhancing the quality of secondary aluminium alloys. The method for improvement of mechanical, foundry, and technological properties of aluminium alloys obtained from recycled raw material was substantiated, elaborated, and tested. It has been shown that application of elaborated modifier substantially improves the properties of studied secondary aluminium alloys.
