Aluminium Molten Metal Treatment (May 2024)
Tuesday 21st May 2024, starting at 14:00 (UK time), and weekly until 9th July 2024
This course comprises 8 weekly sessions, covering the major measures of aluminium molten metal quality: dissolved hydrogen, non-metallic inclusions and alkali metals. In each case, the course covers the origins of that impurity, and the downstream impacts if levels are too high. The measurement methods and their limitations are reviewed, before addressing the technologies available to reduce impurities to acceptable levels.
Each session will consist of a seminar, and an associated workshop.

Aluminium Molten Metal Treatment
Course Agenda
- Development of molten metal treatment
- Origin and measurement of dissolved hydrogen
- Principles of hydrogen removal
- Incluions: origin and measurement
- Inclusion removal (1): furnace operations
- Inclusion removal (2): filtration
- Alkalis: origins and removal
- Grain refinement
Each session lasts typically 2 hours. Following the seminar, attendees are left with a workshop to tackle in their own time before the start of the next session. The subsequent session starts with an interactive review of the previous week's workshop.
