Effect of roasting process on the V (anti-tumor agent) recovery from the slag of the electric arc furnace (EAF)

Heliyon
Due to the lack of mineral sources of Vanadium (V) in many parts of the world and its recent applications in the field of medicine (as an anti-tumor agent), one of the biggest sources of V is the extraction of V as V2O5 from steel slag in melting process.

Utilisation of noise level emitted by the electric arc furnace (EAF) for optimisation of the feeding process of slag foaming materials

Metalurgija, 2022
The present paper reveals methodology of a research and the results of noise level measurements with respect to fluctuations of active power during EAF operation in one of the melt shops in Poland. In the current stage of experiment, the authors focused themselves on finding the optimum moment to start feeding of foaming material with the aim to obtain

Influence of additives on the hydration, pore chemistry and phase assemblage of ferrite-rich steel slag-based cement clinker

Case Studies in Construction Materials
Electric arc furnace slag (EAFs) was used as an alternative material for alite-ferrite (C3S-C4AF) clinker synthesis. Successful synthesis achieved 26 wt% and 70 wt% of C4AF and C3S, that was used for hydration investigation.
