摘要

Following the initial molten metal quality studies with the MetalVision MV 20/20 Inclusion Analyzer1,2,3,4, presented previously, the need for more robust molten metal treatment equipment and methods was identified. Elimination of fluxing gas and improved filtration techniques were identified as opportunities. New degassing and cleaning technologies such as ultrasonic degassing were tested. This paper presents the results obtained during the initial trials of the ultrasonic SCR Ultra-D? Degasser5. Some unexpected and surprising results led to further investigation (theory and confirmation tests), which then led to modifications in equipment and further process improvement.
