   Sammanfattning : This thesis focuses on the AOD process, which is an important metallurgical reactor in stainless steel production. To be more specific, the thesis is limited to study the decarburisation step, which is the first of three process steps in the AOD converter. LÄS MER

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

   Författare :Kristofer Bölke; Mikael Ersson; Pär Jönsson; Stein Tore Johanssen; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

5. 9. Towards full Automation of Robotized Laser Metal-wire Deposition

   Författare :Almir Heralic; Bengt Lennartson; Anna-Karin Christiansson; Giorgos Nikoleris; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser metal wire deposition; process control; process development; optical sensors; robotic weld equipment; Manufacturing engineering; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Metal wire deposition by means of robotized laser welding offers great saving potentials, i.e. reduced costs and reduced lead times, in many different applications, such as fabrication of complex components, repair or modification of high-value components, rapid prototyping and low volume production, especially if the process can be automated.

7. 10. A Study of the Swirling Flow Pattern when Using TurboSwirl in the Casting Process

   Författare :Haitong Bai; Mikael Ersson; Pär Jönsson; Yogeshwar Sahai; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
