1. Supervised Machine Learning Modeling in Secondary Metallurgy : Predicting the Liquid Steel Temperature After the Vacuum Treatment Step of the Vacuum Tank Degasser
Master-uppsats, KTH/MaterialvetenskapSammanfattning : In recent years the steelmaking industry has been subjected to continuous attempts to improve its production route. The main goals has been to increase the competitiveness and to reduce the environmental impact. The development of predictive models has therefore been of crucial importance in order to achieve such optimization. LÄS MER
2. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. LÄS MER
3. Top Gas Blowing Technique to Prevent Slopping in Ladle and Basic Oxygen Steelmaking Process
Master-uppsats, KTH/MaterialvetenskapSammanfattning : In the steel industry, slag foaming plays a crucial role in many steel processes, given its positive impact on the thermal efficiency of the furnace and its life span. However, excessive foaming causes an overflow in the converter known as “slopping”. LÄS MER
4. Practical investigation of mixing phenomena by physical modelling : Scaling criteria applied for bottom gas-stirred water modelling of metallurgical vessels
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Gas stirring is currently the most commonly used method of homogenizing liquid steel in commercial processes. However, due to the harsh environment during the process, physical models built out of e.g. plexiglass have been used to easier understand the complex phenomenon occurring in the process. LÄS MER
5. Dimensionering av matning för nyskänkugn hos SSAB i Oxelösund
Uppsats för yrkesexamina på grundnivå, Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och MaskinteknikSammanfattning : SSAB i Oxelösund ska bygga en ljusbågsugn för konvertering av verksamheten från huvudsakligen malmbaserad produktion till skrotbaserad produktion. I samband med byggandet av ljusbågsugnen kommer en ny 130 kV linje byggas och från denna linje kommer ett nytt 30 kV nät byggas för att mata ljusbågsugnen och två stycken skänkugnar. LÄS MER
