Interfacial Behaviour in Ferroalloys: The Influence of FeMn Slag Composition
Bublik, Sergey; Tangstad, Merete; Einarsrud, Kristian Etienne (Peer reviewed; Journal article, 2022)The present study investigated the interfacial interaction between FeMn alloy and slags of different compositions and basicity from 0.4 to 1.2 in a sessile drop furnace. Interfacial tension between the FeMn alloy and the ... -
Interfacial Behaviour in Ferroalloys: The Influence of Sulfur in FeMn and SiMn Systems
Bublik, Sergey; Bao, Sarina; Tangstad, Merete; Einarsrud, Kristian Etienne (Peer reviewed; Journal article, 2021)The present study has investigated the influence of sulfur content in synthetic FeMn and SiMn from 0 to 1.00 wt pct on interfacial properties between these ferroalloys and slags. The effect of experimental parameters such ... -
Inverse modelling of interfacial tension between ferroalloy and slag using openfoam
Bublik, Sergey; Einarsrud, Kristian Etienne (Chapter, 2020)The entrainment of molten ferroalloy droplets in slag during tapping operations is strongly related to turbulence and interfacial forces between alloy and slag. Therefore, interfacial phenomena are of great importance for ... -
Investigation of Two Immiscible Liquids Wetting at Elevated Temperature: Interaction Between Liquid FeMn Alloy and Liquid Slag
Bao, Sarina; Tangstad, Merete; Tang, Kai; Einarsrud, Kristian Etienne; Syvertsen, Martin; Onsøien, Morten Ingar; Kudyba, Artur; Bublik, Sergey (Peer reviewed; Journal article, 2021)The goal of the current work is to develop a methodology to study the wetting behaviour of two immiscible liquids at high temperatures, and to investigate the parameters which influence the wetting properties. The wetting ... -
A Review of Ferroalloy Tapping Models
Bublik, Sergey; Olsen, Jan Erik; Loomba, Varun; Reynolds, Quinn Gareth; Einarsrud, Kristian Etienne (Peer reviewed; Journal article, 2021)Tapping is an important furnace operation in the ferroalloy industry and poses a number of complex and coupled challenges of both practical and economical importance. Owing to the hazardous high-temperature conditions ... -
Slag Properties in the Primary Production Process of Mn-Ferroalloys
Tangstad, Merete; Bublik, Sergey; Haghdani, Shokouh; Einarsrud, Kristian Etienne; Tang, Kai (Peer reviewed; Journal article, 2021)The present study has investigated the influence of sulfur content in synthetic FeMn and SiMn from 0 to 1.00 wt pct on interfacial properties between these ferroalloys and slags. The effect of experimental parameters such ... -
Slag-metal interactions in the FeMn tapping process: Interfacial properties and wetting
Bublik, Sergey; Bao, Sarina; Tangstad, Merete; Einarsrud, Kristian Etienne (Chapter, 2019)FeMn-alloys are produced by transforming ore and carbon materials into FeMn and slag at high temperatures in a furnace. Entrainment of FeMn in slag during tapping reduces the yield. Entrainment and subsequent separation ... -
Slag-Metal Separation in Mn Ferroalloy Production
Bublik, Sergey (Doctoral thesis, 2022)The separation of slag and metal in the ferroalloy production process is an important issue that has an impact on both the ecological and environmental considerations of the entire production process. The extensive mixing ...
