  4. 2. IronArc a New Process for Pig Iron Production : A Numerical and Experimental Investigation Focusing on Mixing

    Author : Kristofer Bölke; Mikael Ersson; Pär Jönsson; Stein Tore Johanssen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixing time; Penetration depth; CFD simulations; IronArc; Water modeling; Mixing time Experiments; Omrörningstid; Penetrationsdjup; CFD simuleringar; IronArc; Vattenmodellering; Omrörningsexperiment; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : I den här studien så var syftet att undersöka omrörningen och relaterade fenomen i den nyutvecklade IronArc processen. Processen använder sig av gasinjektion genom plasmageneratorer för att smälta och reducera en slagg bestående av järnoxid. READ MORE

  5. 3. A Study of the Swirling Flow Pattern when Using TurboSwirl in the Casting Process

    Author : Haitong Bai; Mikael Ersson; Pär Jönsson; Yogeshwar Sahai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow pattern; swirling flow; TurboSwirl; CFD; turbulence models; water model; flödesmönster; roterandeflöde; TurboSwirl; CFD; turbulensmodeller; vattenmodell; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The use of a swirling flow can provide a more uniform velocity distribution and a calmer filling condition according to previous studies of both ingot and continuous casting processes of steel. However, the existing swirling flow generation methods developed in last decades all have some limitations. READ MORE
