  1. 1. Conditions for Industrial Symbiosis surrounding a hydrogen based steel industry

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Erland Nylund; [2023]
    Nyckelord :Industrial Symbiosis; H-DRI steelmaking; Industrial Symbiosis Networks; Waste management; Supplementary Cementitious Material SCM ; circular economy; Industriell symbios; H-DRI stålproduktion; Industriell Symbios-nätverk; restmaterialhantering; alternativa cementmaterial; SCM ; cirkulär ekonomi.;

    Sammanfattning : There is an ongoing transition to a more sustainable industry with lower climate impact. As part of this transition, the steel industry is expected to move from the conventional process for producing iron and steel using Blast Furnace (BF) and Basic Oxygen Furnace (BOF) processes, consuming large amounts of fossil fuels.

  3. 2. Understanding the potential future capacity of distributing green steel solutions - current knowledge and future challenges

    Magister-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Heba Alwan; [2023]
    Nyckelord :Carbon dioxide CO2 ; greenhouse gas GHG emissions; Steelmaking fossil-free; direct hydrogen reduction; Sustainability transitions.;

    Sammanfattning : Transitioning from the conventional steel process to a direct hydrogen reduction process in the steel industry is a significant step towards reducing carbon dioxide emissions and achieving greater sustainability. The process involves using hydrogen gas as a reducing agent instead of carbon to remove oxygen from the iron ore. LÄS MER

  4. 3. Top Gas Blowing Technique to Prevent Slopping in Ladle and Basic Oxygen Steelmaking Process

    Master-uppsats, KTH/Materialvetenskap

    Författare :Abdullah Harazeen; [2022]
    Nyckelord :slag; slag foaming; slopping prevention; BOS; LD converter; ladle furnace; foaming index; and cold model experiment;

    Sammanfattning : In the steel industry, slag foaming plays a crucial role in many steel processes, given its positive impact on the thermal efficiency of the furnace and its life span. However, excessive foaming causes an overflow in the converter known as “slopping”. LÄS MER

  5. 4. Partitioning of Zn and Cr in Basic Oxygen Steelmaking

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Andreas Persson; [2019]
    Nyckelord :Partitioning; Cr; Zn; BOS;

    Sammanfattning : Steel is the worlds most used metal and 2016 the produced amount of steel was measured to a total1630 MT where the Blast Furnace (BF) - Basic Oxygen Steelmaking (BOS) process, which is the mostcommon steel process, stands for 75% of the world’s current crude steel production.The BOS process works by blowing oxygen at high velocity through a hot metal bath consisting of hotmetal from the blast furnace mixed with fluxing agents as slag formers and up to 30 weights% scrap.
