  1. 1. Heat recovery from vacuum brazing furnaces

    Master-uppsats, Lunds universitet/Avdelningen för Installations- och klimatiseringslära

    Författare :Oliver Robertsson; Rasmus Wikman; [2023]
    Nyckelord :Waste heat; Vacuum furnace; Heat recovery; HVAC; Technology and Engineering;

    Sammanfattning : By partly replacing the use of primary energy sources with waste heat recovery, climate and environmental goals for the future will be closer at hand. This thesis investigates the waste heat potential of Alfa Laval's vacuum brazing furnaces in Ronneby and alternative ways of integrating the furnace's waste heat into the building's HVAC system.

  4. 3. 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/Materialvetenskap

    Författare :Roberto Vita; [2022]
    Nyckelord :Industy 4.0; Machine Learning; Statistical Modeling; Temperature Prediction; Vacuum Tank Degasser; Vacuum Treatment Step.; Industri 4.0; Maskininlärning; Statistisk modellering; Temperaturförutsägelse; Vakuumbehandlingssteg; Vakuumtankavgasare;

    Sammanfattning : 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

  5. 4. Macro composites for crushing - additive manufacturing of hard phase : Development and testing of macro composites for crushing purposes

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Maria Wojtowicz; [2021]
    Nyckelord :stone; rock; crushing; tribology; jaw crusher; selective laser melting; SLM; additive manufacturing; steel; macro composite; bronze;

    Sammanfattning : During this master thesis a crushing material composite was developed in order to determine if a specific design consisting of a pointy hard phase with a ductile phase in between can reduce the load needed to crush stone and therefor decrease the energy consumption during stone crushing. The steel hard phase (ASP 2012) was printed using an additive manufacturing method called selective laser melting (SLM). LÄS MER

  7. 5. Nanocellulose surface functionalization for in-situ growth of zeolitic imidazolate framework 67 and 8

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Beyar Abdulla; [2020]
    Nyckelord :Zeolitic Imidazolate Framework; ZIF-8; ZIF-67; CNF@MOF; CNF@ZIF; TEMPO CNF; Nanomaterials; Nanocomposites; Metal-Organic Framework; Biopolymers;

    Sammanfattning : This master’s thesis was conducted at the Department of Nanotechnology and Functional Materials at Ångström Laboratory as part of an on-going project to develop hybrid nanocomposites from Cladophora cellulose and a sub-type of metal-organic frameworks; zeolitic imidazolate frameworks (ZIFs). By utilizing a state-of-the-art interfacial synthesis approach, in-situ growth of ZIF particles on the cellulose could be achieved. LÄS MER
