Impurities in Ilmenite - Excess Iron
(Master thesis, 2015)During this master s thesis, batches of ilmenite with three different Fe/Ti-ratios were successfully synthesised. After synthesis, the batches underwent pre-oxidation, reduction with ThermoGravimetric Analysis (TGA), before ... -
Interactions between the process and the lining in a silicon furnace - Modelling placments of thermocouples
(Master thesis, 2015)The aim of this thesis is to investigate the interactions between the process and the lining in a silicon furnace. During operation of a silicon furnace incidents may occur that leads to the bottom of the furnace lining ... -
Mass Transfer Coefficients and Bubble Sizes in Oxidative Ladle Refining of Silicon
(Master thesis, 2016)The mass transfer of [Al] and [Ca] between three synthetic SiO_{2}-CaO-Al_{2}O_{3} slags, and 8N silicon, has been investigated to find the overall mass transfer coefficient k_{i,t} for the individual species. Samples were ... -
Reduction Mechanisms in Manganese Ore and Deposition of Carbon from Natural Gas
(Master thesis, 2017)This report investigates the deposition of carbon from natural gas onto manganese ore and the effect of reduction of the higher manganese oxides. Manganese ore has been heated in an argon atmosphere, before methane was ... -
Theoretical study and mathematical modelling on the reaction rates in the SiMn-production process
(Master thesis, 2016)AbstractThe reduction rate of MnO and SiO2in the furnace stage of metallurgical silicomanganese productionhas been studied to increase the current understanding of the SiMn-alloy production process. ...
