  1. 1. Design Solution for Ingot Handling and Machining

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Johan Jönsson; [2021]
    Keywords : Mechanical Engineering; Product Development;

    Abstract : At the electro remelting slag (ESR) facility at Uddeholm, cylindrical steel ingots are produced in several different sizes. The ESR process requires a “starting step” that consist of a 20mm thick steel plate and is a little larger than the diameter of the ingot. READ MORE

  3. 2. Nitrogen Without Oxygen : The effect of ferroalloys added after vacuum treatment on cleanliness of nitrogen-alloyed tool steel

    University essay from KTH/Materialvetenskap

    Author : Leo Nilsson Hultén; [2021]
    Keywords : Tool steel; Electro-Slag Remelting ESR; Nitrogen Alloying; Ferroalloys; Nonmetallic Inclusions NMI; Verktygsstål; Elektroslaggomsmältning ESR; Kvävelegering; Ferrolegeringar; Ickemetalliska Inneslutningar NMI;

    Abstract : Nitrogen-alloyed tool steel is made at Uddeholms AB by adding high-nitrogen ferroalloy after vacuum degassing where introduced impurities are hard to remove. In this thesis two types of high-nitrogen ferrochromium are compared, a solid version and a powder cored wire. READ MORE

  4. 3. Statistical Study on Langmuir Turbulence Radar Signatures Observed by the ESR

    University essay from KTH/Rymd- och plasmafysik

    Author : Alexander Karlsson; [2015]
    Keywords : ;

    Abstract : In this thesis data taken by the EISCAT Svalbard Radar during the International PolarYear have been analyzed. The radar data have been searched for anomalous radarechoes. These radar echoes appear in an altitude range between 200 and 300 km, showa strong enhancement of the backscattered power and are limited in altitude to tensof kilometers. READ MORE

  5. 4. Design of a DC/DC buck converter for ultra-low power applications in 65nm CMOS Process

    University essay from Elektroniska komponenter; Tekniska högskolan

    Author : Naeim Safari; [2012]
    Keywords : DC DC Converter; Buck; SMPS; Compensation Network; VMC; CMC; ESR; Pulse Width Modulation;

    Abstract : Switching mode DC/DC converters are critical building blocks in portable devices and hence their power efficiency, accuracy and cost are a major issue. The primary focus of this thesis is to address these critical issues. READ MORE

  6. 5. Optimization of the polishing procedure using a robot assisted polishing equipment

    University essay from Sektionen för ekonomi och teknik (SET)

    Author : Marielle Gagnolet; [2009]
    Keywords : high gloss polishing; surface characterisation; design of experiments;

    Abstract : Today, manual polishing is the most common method to improve the surface finish of mould and dies for e.g. plastic injection moulding, although it is a cumbersome and time-consuming process. Therefore, automated robots are being developed in order to speed up and secure the final result of this important final process. READ MORE
