1. 6. Potential methods of measuring the stirring intensity during secondary steel making in the ladle furnace

   University essay from KTH/Materialvetenskap

   Author : Karin Törner; Sofie Nabseth; [2016]
   Keywords : ;

   Abstract : The main objectives of this research were to find a measuring technique for the gas stirring intensity and relate this to the argon gas stirring in the ladle furnace. However, the investigation mainly focused on methods of measuring the true amount of argon gas entering the ladle furnace, since this was needed to further determine the gas stirring intensity.

3. 7. Dissolution kinetic study of limonene in supercritical carbon dioxide by in-situ Raman spectroscopy

   University essay from Lunds universitet/Kemiska institutionen

   Author : Cristiana Buzolin; [2016]
   Keywords : limonene; Raman spectroscopy; supercritical carbon dioxide; dissolution kinetics; solubility; analytical chemistry; analytisk kemi; Chemistry;

   Abstract : Understanding the dissolution kinetics is important in the experimental determination of solubility, the efficiency of extractions, the rate of reactions and in general any heterogeneous process. Despite the extensive use of supercritical fluids, studies regarding the dissolution kinetics of compounds in supercritical carbon dioxide (scCO2) using analytical methods are limited in the literature.

4. 8. Optimisation of the bottom stirring praxis in a LD-LBE converter : Investigations and tests on phosphorous removal, nitrogen as stirring gas, and slopping

   University essay from Uppsala universitet/Oorganisk kemi

   Author : José Aguirre Castillo; [2015]
   Keywords : LD; BOS; Bottom Stirring; Phosphorous; Steel making; Nitrogen;

   Abstract : The LD-process, called after the cities Linz and Donawitz, is used to convert pig iron into crude steel by blowing oxygen on top of the pig iron. A LD-LBE converter, Lance Bubbling Equilibrium, also stirs the melt trough a bottom stirring system. READ MORE

5. 9. A desulphurization study of hot metal at SSAB Europe Luleå with added bottom stirring of nitrogen gas

   University essay from KTH/Materialvetenskap

   Author : Mattias Edvartsen; [2015]
   Keywords : desulphurization; desulfurizing; removal of sulfur; steel; bottom stirring.;

   Abstract : This bachelor degree project is about determining the impact that additional bottom stirring may have on the desulphurization process at SSAB Luleå. During one week of field work steel samples were collected from 39 different heats. READ MORE

6. 10. Optimization of Expancel Product and Process : Through the use of Multivariate Planning, Data Analysis and Evaluation.

   University essay from Kemiska institutionen

   Author : Evelina Waltersson; [2012]
   Keywords : ;

   Abstract : The company Expancel produces expandable microspheres. The microspheres are microscopic spherical particles that consist of a polymer shell encapsulating a gas (the blowing agent). Heat causes the particles to expand. READ MORE
