  1. 1. Degradation Mechanisms of Heat Resistant Steel at Elevated Temperatures In an Iron Ore Pelletizing Industry

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Erik A. A. Nilsson; Marta-Lena Antti; Ragnar Tegman; Jan-Erik Svensson; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; Grate-Kiln; microstructure; corrosion; as-casted; thermal cycling; erosion; deposition; Engineering Materials; Materialteknik;

    Sammanfattning : This thesis focuses on the different degradation mechanisms of the stainless steel in a travelling grate in a Grate-Kiln iron ore pellet indurator. The travelling grate is a conveyor belt that transports green-body pellets to a rotary kiln while the pellets are being dried and pre-heated to a temperature of 900-1100 °C by recycled hot air.

  2. 2. Learning and Returning : Return Migration of Swedish Engineers from the United States, 1880-1940

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Per-Olof Grönberg; Umeå universitet.; [2003]
    Nyckelord :HUMANIORA; HUMANITIES; History; emigration; return migration; engineers; technology transfer; Sweden; United States; industrialisation; electrical industry; steel and iron industry; mining; engineering industry; Historia; HUMANITIES and RELIGION History and philosophy subjects History subjects; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Historieämnen; History; historia;

    Sammanfattning : This thesis examines different aspects of international migration and return migration among Swedish engineers – particularly to and from the United States between 1880 and 1940. The social, geographical, and educational backgrounds of these engineers and their role in diffusing technological knowledge in Sweden in addition to being a possible source of technical development during the country’s second industrial breakthrough is of particular interest.

  3. 3. Reducing Carbon Dioxide Emissions from the EU Power and Industry Sectors - An assessment of key technologies and measures

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Johan Rootzén; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industry; carbon dioxide; cement; European Union; technologies; emission reductions; CCS; power; steel; CO2< sub>; refining; mitigation;

    Sammanfattning : In February 2011, the European Council reconfirmed the goal of reducing EU greenhouse gas emissions by at least 80% by 2050, as compared to the levels in 1990. The power and industrial sectors currently account for almost half of the total GHG emissions in the EU. LÄS MER

    Sammanfattning : Halterna av växthusgaserna koldioxid (CO2), metan och kväveoxider har under de senaste 800 000 åren aldrig varit högre i atmosfären än vad de är idag. Detta resultat redovisades i IPCCs klimatrapport år 2013. LÄS MER

  5. 5. On particles and slags in steel casting

    Detta är en avhandling från Jönköping : Jönköping University, School of Engineering

    Författare :Dimitrios Siafakas; Högskolan i Jönköping.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hadfield steel; deoxidation; grain size; inoculation; particles; viscosity; slag;

    Sammanfattning : Hadfield steel is widely accepted as one of the most important steel alloys utilized in industrial applications where high impact strength and wear resistance is required. Like in most metallic alloys used for component casting, the mechanical properties of Hadfield steel are directly connected with the microstructure of the material. LÄS MER
