摘要

In the '80s, Pechiney developed a furnace treatment technology aiming at a significant quality increase of aluminum alloys. The technology is based on rotary gas treatment. Since its first implementation, this technology has developed widely inside Pechiney casthouses. The paper reviews the basics of the technology. The improvements of the molten metal quality that can be obtained through this technology are presented in detail: hydrogen, inclusion, and alkaline or alkaline-earth elements removal. The environmental benefits of the IRMA technology are also illustrated.
