Publication metadata
This collaborative project was coordinated by Tata Steel UK. It involved Gerdau- Sidenor I+D, voestalpine Stahl Donawitz GmbH (VASD), BFI, ArcelorMittal Research and Aalto University (TKK). The objective of this research was to improve steel cleanness, including improvement of the size and distribution of inclusions in the cast product, and to improve its final properties. The processing conditions and segregation were aimed at improving the use of conventional single mode and modern multimode mould electromagnetic stirring for long and flat products. The characterisation of the data and cast industrial samples at Tata Steel, Sidenor, VASD and ArcelorMittal using modified stirring, laboratory ductility investigations, offline and in-mould measurements of meniscus velocity, temperature, flow and surface waves height have helped to optimise the casting conditions for different casting formats. The improved steel cleanness, minimised powder entrapment and energy savings were achieved using practical information on flow and inclusions, supported by numerical and physical modelling by BFI, ArcelorMittal, TKK and Sidenor. The numerical models were validated with the practical information on inclusions and meniscus flow. The novel application of EM forces to control the meniscus flow and flow in the SEN was also investigated. Laboratory-based feasibility studies using the trial facilities at Forschungszentrum Dresden-Rossendorf (FZD), Germany, and the numerical and physical modelling by BFI, TKK and ArcelorMittal Research have shown that the rotational frequency of the external stirrer changed the flow within the SEN and in the mould. This has opened the way to assess the practical application of this technology on a larger scale casting.
