| Abstract Scope |
Non-metallic inclusions are a major concern in aluminium production, particularly in critical applications where metal cleanliness is paramount. Existing detection technologies offer partial insights but fail to provide continuous, representative measurements of the full cast.
BATSCANŽ, developed by Constellium and commercialized by STAS, introduces an accurate and reliable method of assessing molten metal cleanliness. Using ultrasonic waves transmitted through inert ceramic waveguides, BATSCANŽ enables real-time inclusion detection and measurement with minimal process interference. BATSCANŽ can be deployed at any point on the casting line, whether it is at the furnace exit, after the degasser, or after the filter. It can monitor from the beginning to the end of the casting sequence.
This paper presents a comparative evaluation of BATSCANŽ, LiMCA III, and PoDFA based on recent industrial trials. Measurements were conducted at both furnace and filter exits to capture statistically significant data and assess detection sensitivity across technologies. |
