  1. 1. Development and analysis of fire suppresion during steel quenching : Three paths of analysis of fire- and smoke suppresion during steel hardening processes

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Alex Eidersjö; [2023]
    Keywords : Product development; Produktutveckling;

    Abstract : This thesis looks at an issue of excessive fire and smoke development during open tank quenching. The quenching in question being done as part of a hardening process of steel springs during manufacturing at Lesjöfors Fjädrar AB. The thesis was written under supervision of of Rejlers Sweden AB.

  3. 2. Fast Pyrolysis of Biomass in a Fluidized Bed for Production of Bio-oil and Upgradation by Ex-situ Catalytic Bed

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Samina Gulshan; [2019]
    Keywords : ;

    Abstract : Production of bio-oil from biomass is now becoming best substitute of fossil fuels in the transportation sector. Pyrolysis is one of the most promising route to produce bio-oil from biomass.  However, bio-oil needs to be upgraded due to presence of high percentage of oxygenated compounds. READ MORE

  4. 3. Modelling of Biomass Pyrolysis with Ex-situ Catalytic Upgrading for Bio-crude Production

    University essay from KTH/Materialvetenskap

    Author : Febryana Nugrahany; [2018]
    Keywords : ex-situ catalytic upgrading; slow pyrolysis; screw reactor; fixed bed catalytic reactor; process design;

    Abstract : This study presents a techno-economic assessment of slow pyrolysis of pine sawdust continued by ex-situ catalytic upgrading. The overall process consists of six sections: feed drying, pyrolysis, vapor filtration, ex-situ catalytic upgrading, vapor quenching, and combustion of permanent gas. READ MORE

  5. 4. Distortion Analysis of Low Pressure Carburized Components : A heat treatment distortion comparison of transmission gear components for truck and automobile.

    University essay from KTH/Materialvetenskap

    Author : Frisk Robin; [2016]
    Keywords : Low pressure carburization; high pressure gas quenching; oil quenching; distortion; shape change; gear wheel; crown wheel; truck; automobile;

    Abstract : During the last 10 years, low pressure carburizing and high pressure gas quenching has become more popular since it is a “new” process and researchers reports that the distortion characteristics gained from these processes is improved in relation to conventional processes. The aim of this work was to investigate the distortions gained from three different heat treatment processes on main shaft gears and crown wheels. READ MORE

  6. 5. Quenching distortion in AISI E52100 steel

    University essay from KTH/Materialvetenskap
