An Investigation of Non-Metallic Inclusions in Different Ferroalloys using Electrolytic Extraction
Metals, 2019 Ferroalloys are integral constituents of the steelmaking process, since non-metallic inclusions (NMIs) from ferroalloys significantly influence the transformation of inclusions present in liquid steel or they are directly involved in casted steel.

Method to predict alloy yield based on multiple raw material conditions and a PSO-LSTM network
Journal of Materials Research and Technology, 2023 The production of ferroalloys accounts for a large proportion of the total energy consumption of the steelmaking industry. Accurately predicting alloy element yields is the key to reducing alloy waste, but there are significant differences in alloy yield
