    • CFD Study on Continuous Tapping of Silicon 

      Olsen, Jan Erik; Ksiazek, Michal Tomasz; Tangstad, Merete (Peer reviewed; Journal article, 2022)
      Silicon is mostly produced in rotating submerged arc furnaces with continuous tapping of metal. The burden is often dense due to condensates. Thus, furnace gas does not escape easily to the top of the burden and some gas ...

    • Conceptual Tapping Model of Mn-Ferroalloy Furnaces 

      Tangstad, Merete; Olsen, Jan Erik; Ringdalen, Eli; Ksiazek, Michal Tomasz; Reynolds, Quinn; Steenkamp, Joalet (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 ...

    • Reduction of SiO2 to SiC using natural gas 

      Ksiazek, Michal Tomasz; Tangstad, Merete; Dalaker, Halvor; Ringdalen, Eli (Journal article; Peer reviewed, 2014)
      This paper presents a preliminary study of SiC production by use of natural gas for reduction of silica. Direct reduction of SiO2 by gas mixtures containing CH4, H2, and Ar was studied at temperatures between 1273 K and ...

    • Tapping Gas from the Silicon Submerged Arc Furnace: An Industrial Measurement Campaign 

      Andersen, Vegar; Gaertner, Heiko; Grådahl, Svend; Ksiazek, Michal Tomasz; Einarsrud, Kristian Etienne; Tranell, Gabriella (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 ...
