1. The Kinetics of Water Removal From an Iron Ore Pellet Prior to Hydrogen Reduction
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Humanity is facing one of the biggest challenges ever presented in fighting climate change. To counter global warming, industries and scientists across the world are shifting manufacturing towards fossil independence in order to decrease emissions. LÄS MER
2. Towards Understanding slag build-up in a Grate-Kiln furnace : A study of what parameters in the Grate-Kiln furnace leads to increased slag build-up, in a modern pellet production kiln
Master-uppsats, Linköpings universitet/Institutionen för datavetenskapSammanfattning : As more data is being gathered in industrial production facilities, the interest in applying machine learning models to the data is growing. This includes the iron ore mining industry, and in particular the build-up of slag in grate-kiln furnaces. LÄS MER
3. System analysis of a fossil free steel manufacturing plant powered by an offshore wind power farm
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : Major changes are taking place in the Sweden’s electricity system and steel industry. Through political agreements, the current government has set national goals of 100% renewable electricity generation and a net zero GHG emissions industry by 2040. This will be achieved by increasing renewable power generation, mainly wind power. LÄS MER
4. Life cycle assessment of coal based direct-reduced iron production in India
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The production of iron through direct reduction (Direct-Reduced Iron; DRI) involves the use of natural gas or coal to reduce iron ore to iron through carbothermic reactions at a temperature below its melting point, negating the need for a blast furnace as otherwise required. In India, around 25% of iron is produced through direct reduction. LÄS MER
5. Multivariat dataanalys för att undersöka temperaturmätningar av pelletskulor : En studie för LKAB med syftet att undersöka temperaturvariationer mellan två mätsystem
Kandidat-uppsats, Umeå universitet/StatistikSammanfattning : LKAB (Loussavaara-Kiirunavaara AB) är en högteknologisk gruv- och mineralkoncern som främst arbetar med att bryta och förädla järnmalm. Den huvudsakliga delen av järnmalmen blir till pelletskulor. Detta arbete är genomfört på LKAB:s avdelning Forskning och Utbildning i Malmberget. LÄS MER
