  1. 1. An Experimental Study to Improve the Casting Performance of Steel Grades Sensitive for Clogging

    Författare :Jennie Svensson; Pär Jönsson; Voicu Brabie; Lauri Holappa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Preheating; Decarburization; RBM; Clogging; SEN; Plasma sprayed coating; CaTiO3; YSZ; Continuous casting; Pilot plant trials; Industrial plant trials; Clean steel; Tundish; Non-metallic inclusions; MISS; Materials Science and Engineering; Teknisk materialvetenskap; Steel Forming and Surface Engineering;

    Sammanfattning : In this study, the goal is to optimize the process and to reduce the clogging tendency during the continuous casting process. The focus is on clogging when the refractory base material (RBM) in the SEN is in contact with the liquid steel. LÄS MER

  3. 2. Improvement of Wastewater Sludge Digestion

    Författare :Michael Recktenwald; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anaerobic digestion; biogas; cation-binding agents; enzymes; enzymatic activity; extracellular polymeric substances EPS ; industrial scale trials; methanization; municipal sewage; sludge treatment; wastewater treatment plant;

    Sammanfattning : The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. LÄS MER

  4. 3. A Study of Parameters that Influence the Kinetics of the AOD Decarburisation Process

    Författare :Patrik Ternstedt; Anders Tilliander; Ville-Valteri Visuri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOD; decarburization; steel; slags; composition; petrography; physical modeling; industrial plant trials; AOD; avkolning; stål; slagg; sammansättning; petrografi; fysikalisk modellering; industriella försök; Teknisk materialvetenskap; Materials Science and Engineering; Metallurgical process science; Metallurgisk processvetenskap;

    Sammanfattning : This thesis focuses on the AOD process, which is an important metallurgical reactor in stainless steel production. To be more specific, the thesis is limited to study the decarburisation step, which is the first of three process steps in the AOD converter. LÄS MER

  5. 4. Recycling of Blast Furnace Sludge within the Integrated Steel Plant : Potential for Complete Recycling and Influence on Operation

    Författare :Anton Andersson; Lena Sundqvist Ökvist; Hesham Ahmed; Caisa Samuelsson; Yongxiang Yang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Ore-based steelmaking generates various residues including dust, sludges, scales and slags. Internal and external recycling has allowed for 68-90 % of the dust, sludges and scales to be recycled. However, several residues are landfilled despite containing elements valuable as raw material in the production of steel. LÄS MER

  7. 5. District Heating-driven Membrane Distillation for Water Purification in Industrial Applications

    Författare :Daniel Minilu Woldemariam; Andrew Martin; Massimo Santarelli; Wojciech Kujawski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Distillation; District Heating; Wastewater Purification; Heat demand; Technoeconomy; Membrandestillation; Fjärrvärme; Avloppsvattenrening; Värme-behov; Teknoekonomi; Energy Technology; Energiteknik;

    Sammanfattning : Domestic and industrial water demands are growing globally due to population growth and rapid economic development, placing increasing strains on water resources. Wastewater effluents generated from these and other activities impact the environment and are thus subject to tightening regulation. LÄS MER
