2. 1. A study on the Submerged Entry Nozzels (SEN) respecting clogging and decarburization

   Author : Arashk Memarpour; Pär Jönsson; Sune Jansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory; SEN; Clogging; REM; Coating; glaze; alkaline; Refractory; ZrSi2; Graphite; Alumina; Oxidation; Al2O3-C; ZrO2-C; MgO-C; decarburization; reaction mechanism; Materials science; Teknisk materialvetenskap;

   Abstract : The submerged entry nozzle (SEN) has been used to transport the molten steel from tundish to the mould. The main purpose of the SEN usage is both to prevent oxygen and nitrogen pick-up by molten steel and to achieve the desired flow condition in the mould. READ MORE

4. 2. An Experimental Study of Submerged Entry Nozzles (SEN) Focusing on Decarburization and Clogging

   Author : Arashk Memarpour; Pär Jönsson; Torbjörn Carlberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory; SEN; Clogging; REM; Coating; glaze; alkaline; Post- Mortem; industrial preheating; ZrSi2; Graphite; Alumina; Oxidation; Al2O3-C; ZrO2-C; MgO-C; decarburization; reaction mechanism; Yttria Stabilized Zirconia; plasma spray-PVD coating;

   Abstract : The submerged entry nozzle (SEN) is used to transport the molten steel from a tundish to a mould. The main purpose of its usage is to prevent oxygen and nitrogen pick-up by molten steel from the gas. Furthermore, to achieve the desired flow conditions in the mould. READ MORE

5. 3. A Study on the Reaction between MgO Based Refractories and Slag-Towards the Development of Carbon-free Lining Material

   Author : Huijun Wang; Sichen Du; Stuart Millman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MgO refractory; lining material; carbon-free; clean steel; ladle glaze; slag penetration; dissolution mechanism; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : In present thesis, the fundamental studies on the reaction between MgO based refractories and slag were undertaken for the development of a carbon-free bonding MgO lining material. Alumina was selected as a potential binder material. Due to MgO-Al2O3 chemical reaction, the developed refractory was bonded by MgO·Al2O3 spinel phase. READ MORE

6. 4. A Study on the Correlation between Ladle Glaze and Non-Metallic Inclusions in the Ladle Treatment

   Author : Minho Song; Du Sichen; Jerome P. Downey; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-metallic inclusions; ladle treatment; ladle glaze; tracer; tool steel; viscosity; activity; modelling; Al2O3-CaO-MgO-SiO2 system; Materials science; Teknisk materialvetenskap;

   Abstract : In the present thesis, the correlation between ladle glaze and non-metallic inclusions in the ladle treatment was studied. A number of industrial trials with full scale ladle and laboratory works were performed to investigate the inclusions in the ladle treatment. READ MORE

7. 5. Some Fundamental Aspects Concerning Secondary Steelmaking

   Author : Jimmy Gran; Du Sichen; Tooru Matsumiya; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

   Abstract : The present thesis deals with some aspects concerning secondary metallurgy of steel where there is little or very inconsistent information in the literature. More specifically, it is devoted to the studies on high temperature phase equilibria in the Al2O3-CaO-MgO-SiO2 system, the formation of ladle glaze and the thermodynamics of magnesium in liquid iron.
