An efficient inline melt treatment process is a key prerequisite for Aluminum producers to ensure compliance to today’s product requirements.
Modern DC-casting lines use an equipment chain including Argon degassing, grain refiner addition and mechanical filtration to reduce hydrogen and non-metallic inclusions to low levels. Individual units of this process chain have been adapted to twin roll casting (TRC) conditions with low melt flow rates, long casting campaigns and high temperature sensitivity, while a holistic concept is pending.
Speira and Drache initiated a project to develop a TRC degassing & filtration unit based on joint experience combining Argon degassing, CFF filtration and immersion heater temperature management into a user-friendly single box concept with small footprint and high metallurgical performance.
This paper describes the technological approach for degassing, filtration and electrical heating, the integration into a single-unit concept and initial results of the pilot installation at Speira Karmoy.
