1. 1. Enabling Collaboration for Industrial Symbiosis Formation between Manufacturing Firms : A Study of the Norrbotten & Västerbotten Region

   University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Author : Anton Nygårdh; [2023]
   Keywords : Industrial symbiosis; Collaboration; Challenges; Strategies; Manufacturing industry; Norrland; Industriell Symbios; Samarbete; Utmaningar; Strategier; Tillverkningsindustri; Norrland;

   Abstract : Purpose: The purpose of this thesis is to enhance the understanding of how collaboration in the manufacturing industry can enable the formation of industrial symbiosis by identifying challenges and strategies. To fulfill this purpose, two research questions has been addressed: What are the factors hindering collaboration and thus IS formation between companies in Norr- & Västerbotten? and What are the enabling strategies allowing collaboration for IS formation in Norr- & Västerbotten? Method: The research was conducted as a qualitative, inductive study of exploratory nature. READ MORE

3. 2. Challenges and Metallurgical Benefits of Implementing Metal Additive Manufacturing : A Case Study on Excavator Bucket Teeth Comparing Sand Casting with Additive Manufacturing

   University essay from Mälardalens universitet/Akademin för innovation, design och teknik

   Author : Sam Thai; Michael Thunberg; [2023]
   Keywords : Challenges; Electron Beam Melting; Metal Additive Manufacturing; Metallurgy; Microstructure; Porosity; Qualification; Sand Casting;

   Abstract : Introduction: Production systems go through changes over time and there are different factors driving the change. Metal Additive manufacturing (AM) could be a factor with industries that already havetaken interest in the manufacturing technique. READ MORE

4. 3. Projection Nut Welding to High- and Ultra-high Strength Steels

   University essay from KTH/Hållfasthetslära

   Author : Love Englund; [2023]
   Keywords : mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

   Abstract : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. READ MORE

5. 4. Techno-economic evaluation of hydrochar via hydrothermal carbonisation of organicresidues

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Abdirahman Abdullahi; [2022]
   Keywords : Technoeconomic analysis; energy system modelling; HTC; hyrochar; system integration; OSMET;

   Abstract : This thesis has investigated the techno-economic feasibility of upgrading the sludge from a chemical pulp mill to hydrochar via hydrothermal carbonization (HTC). The intended use of the hydrochar was to replace fossil coal within metallurgical applications in the iron and steel industry. READ MORE

6. 5. Improving Availability of the Pelletization Process

   University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

   Author : Emil Andreasson; Pontus Åhman; [2022]
   Keywords : Availability; Predictive Maintenance; Pelletization; Statistical Process Control; Refractory Material; DMAIC;

   Abstract : The Grate-Kiln-Cooler process is a commonly used method of sintering during iron ore pelletization, where the pellets are formed, dried, and hardened. The pellets are oxidized in the rotating Kiln, turning magnetite (Fe3O4) to hematite (Fe2O3), making the pellets attain suitable metallurgical attributes for further processing. READ MORE
