  1. 1. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    University essay from KTH/Materialvetenskap

    Author : Hagen Christian Hagens; [2022]
    Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

  3. 2. Wood powder production with a novel milling technology : analysis of specific energy consumption and of the product’s bulk properties

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Tobias Holdo; [2020]
    Keywords : log mill; hammer mill; tapped density; loose density; hausner ratio; biomass; flowability;

    Abstract : The interest for lignocellulose biomass has grown strongly in the last decades due to its potential to substitute fossil fuels. Pre-processing of biomass is of-ten needed to enable utilization of its full potential. A common pre-processing step is milling where the biomass is fractionated into wood powder usable for e.g. READ MORE

  4. 3. Advanced hybrid manufacturing process for high precision ring of a planetary gear – main focus on Abrasive Waterjet Machining

    University essay from KTH/Industriell produktion

    Author : BOGDAN GOTIA; JORGE LOYA MUCINO; [2016]
    Keywords : Abrasive waterjet machining; AWJM; precision gear; gear manufacturing; Hybrid manufacturing;

    Abstract : Under år 2008 uppskattades den totala produktionen av kugghjul inom bilindustrin till 2000 – 2500 miljoner detaljer, varav 1000 - 1400 miljoner av dessa är av hög kvalité [1]. För precisionskugghjul med modul under 1 mm kan tidsbegränsning och kostnader kopplade till design av skärverktyget elimineras genom att tillämpa en flexibel tillverkningsmetod som tillexempel abrasiv vattenskärning (AWJM).

  5. 4. Engreppsskördarens tekniska utveckling

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Daniel Persson; [2016]
    Keywords : skördare; aggregat; avverkning; avverkningsmaskiner; skogstraktorer; skogshistoria; maskindata;

    Abstract : Historiskt finns det ett väldigt stort spann av olika skogsmaskiner. Redan efter andra världskriget började maskiner ersätta hästar och människor. År 1965 kom de första avverkningsmaskinerna och 1966 tillverkades den första avverkningsmaskinen i Sverige. Mekaniseringen innebar stor produktivitetsökning inom skogsbruket. READ MORE

  6. 5. Ablation of Si with femtosecond laser

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Stefano Prevosti; [2016]
    Keywords : ;

    Abstract : Femtosecond laser ablation of different materials is becoming more and more important in micro- and nanomachining fields. The cutting precision and cost-effectiveness related to this method are turning it into a valid alternative to traditional methods. READ MORE
