RECENT DEVELOPMENTS IN ALUMINUM SCRAP MELTING UPDATE

摘要

Awareness of the potential to improve aluminum melting productivity using various molten metal pumping and stirring technologies has increased significantly in the past few years. In addition, the need for achieving highest recoveries when melting scrap, and improving energy efficiency and metal quality have become ever more serious objectives. Recent advances in improving gas injection technology, and incorporation of new molten metal centrifugal pumping design using composite materials have resulted in enhanced performance in many remelters. This development also has application to closed hearth melters/holders as well. This paper focuses on these recent developments and is a continuation of information presented in previous Casthouse Technology Conferences.
