Aluminum Recovery from White Aluminum Dross by a Mechanically Activated Phase Separation and Remelting Process
(Journal article; Peer reviewed, 2021)The aluminum recovery from white aluminum dross by a mechanical treatment and sizing followed by remelting process was investigated. The dross was subjected to a ball mill, and the obtained particles were sized in different ... -
CO2 Gasification of Densified Biomass: The Influence of K on Reaction Rate
(Peer reviewed; Journal article, 2022)The Boudouard reactivity of metallurgical coke and densified charcoals was investigated in this study. Potassium is known to accumulate in ferromanganese furnaces and hence was evaluated as a catalyst of CO2 reactivity. ... -
Composition and Structure Analysis of Hard Grey Scale (HGS) Formed on Cold Surfaces Exposed to Aluminium Production Off-gas
(Peer reviewed; Journal article, 2022)Hard grey scale (HGS) is a strongly adhering fouling material forming on solid surfaces impinged by off-gas generated in the pot cells of primary aluminium production plants. Even though associated maintenance costs have ... -
Conceptual Tapping Model of Mn-Ferroalloy Furnaces
(Peer reviewed; Journal article, 2022)The tapping process of submerged arc furnaces, like the Mn-ferroalloy production process, is when you drain the liquid metal and slag from the furnace. The optimal tapping process is when slag and metal is drained from the ... -
The Effect of Electrode Movements on Electrical Characteristics of a Submerged Arc Furnace
(Peer reviewed; Journal article, 2021)This work discusses the effect of electrode position on the electrical characteristics of a submerged arc furnace. A 3D model has been developed in ANSYS Maxwell using an eddy current solver that considers alternating ... -
Gas Flow and Pressure Drop in Charge Material in Silicon Production
(Peer reviewed; Journal article, 2022)Gassing, outbursts of high-rate gas flows through the taphole, is a phenomenon that sometimes occurs during tapping of silicon furnaces. In addition to being an HSE challenge, this might also affect the tapping, while the ... -
An Overall Furnace Model for the Silicomanganese Process
(Journal article; Peer reviewed, 2021)An overall model for a pilot-scale silicomanganese furnace that simultaneously considers electrical and thermal conditions, process chemistry, and flow of solid and liquid substances. -
Physical and Mechanical Properties of Graphene Nanoplatelets Reinforced Al6061-T6 Composites processed by Spark Plasma Sintering
(Peer reviewed; Journal article, 2020)Aluminium matrix composites with high specific strength are attracting attention for use in automobile and aerospace applications. Graphene nanoplatelets (GNPs) were added in 0.1, 0.5, and 1 weight fractions to an Al6061 ... -
Tapping Gas from the Silicon Submerged Arc Furnace: An Industrial Measurement Campaign
(Journal article; Peer reviewed, 2022)Producing high-silicon alloys in submerged arc furnaces (SAF) involves the generation of an intermediate process gas, consisting of silicon monoxide (SiO) and carbon monoxide (CO). Combustion of process gas from the taphole ... -
Use of a Distributed Micro-sensor System for Monitoring the Indoor Particulate Matter Concentration in the Atmosphere of Ferroalloy Production Plants
(Peer reviewed; Journal article, 2022)Airborne particulate matter (PM) is a concern for both occupational health and the environment, and, in the ferroalloy industry, the level of such particles in the air can be considerable. Small, low-cost sensors for ...
