  1. 1. Design Solution for Ingot Handling and Machining

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Johan Jönsson; [2021]
    Nyckelord :Mechanical Engineering; Product Development;

    Sammanfattning : 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. LÄS MER

  2. 2. Casting and Characterization of Advanced High Strength Steels

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Daniel Hedman; [2020]
    Nyckelord :AHSS; characterization; casting; parlite; austenite; martensite; ferrite; grain size;

    Sammanfattning : The Latin American steel making company Ternium S.A. aims to develop and produce a new type of advanced high strength steel (AHSS) in which the main alloying elements are carbon, aluminium, manganese, and silicon. LÄS MER

  3. 3. Distortions of Press Quenched Crown Wheels

    Master-uppsats, KTH/Materialvetenskap

    Författare :Benjamin Brash; [2015]
    Nyckelord :Press quenching; Distortions; Crown wheel; Segregation; Ingot casting; Continuous casting;

    Sammanfattning : Scania has experienced difficulties with large variations of the slope of the back plane after press quenching of case hardened crown wheels of especially type R780 Steg supplied from ingot cast material. This leads to that a large number of crown wheels has to be remeasured and sorted according to back slope which is time consuming for operators. LÄS MER

  4. 4. Glödskalsrensning på göt med varierande tvärsnitt

    M1-uppsats, Högskolan i Gävle/Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Författare :Mattias Oppitz; [2015]
    Nyckelord :scale; primary scale; descale; descaling; oxide; oxidation; ingot; high-pressure; water; glödskal; glödskalsrensning; oxid; oxidering; göt; högtrycksvatten;

    Sammanfattning : På Ovako i Hofors, framställs stål via götgjutning. Göten har ett kvadratiskt tvärsnitt som varierar mellan 300 och 700 mm. Dessa transporteras från stålverket, till valsverket för uppvärmning. Varpå de varmvalsas till färdiga ämnen. LÄS MER

  5. 5. Study of Argon Shrouding in Ingot Casting, with Focus on Improving the Operation at Scana Björneborg Steel Plant

    Master-uppsats, KTH/Materialvetenskap

    Författare :Babak Ghazian Tafrishi; [2014]
    Nyckelord :uphill ingot casting; argon shrouding; steel; oxygen nitrogen uptake; stigande götgjutning; skyddad gjutning; stål; syre upptagning;

    Sammanfattning : This thesis has been carried out as a development project at Scana Steel Björneborg with the purpose to study the influential parameters in argon shrouded ingot casting during the manufacturing of low-alloy steels. In the first stage, a literature study was conducted in order to investigate the theoretical background of the procedure and the importance of protecting the melt during ingot casting. LÄS MER
