  1. 1. Improved Furnace Control : System identification and model predicative control of Outokumpu’s reheating furnace

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Oscar Holmqvist; [2023]
    Nyckelord :Systeem Identification; Model Predictive Control;

    Sammanfattning : This thesis investigates one option for improving the control of a reheating furnace used in heating steel slabs before hot rolling; an essential part of the steel manufacturing process. The furnace consumes a significant amount of energy, leading to high cost and high carbon dioxide emissions. LÄS MER

  3. 2. Air Cooling Analysis of Forged Bearing Steels

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Mattias Sörlander; [2022]
    Nyckelord :Material; Bearing steel; Cooling;

    Sammanfattning : This thesis work was done in cooperation with Ovako Sweden AB in Hofors to better understand and improve cracking-related problems in bearing ring production and cooling after forging in particular. This goal was achieved by doing a literature search and executing cooling experiments in live production. LÄS MER

  4. 3. Digital Twin of a Reheating Furnace

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Daniel Halme Ståhlberg; [2021]
    Nyckelord :Machine Learning; Digital Twin; Reheating Furnace; Steel Industry; Tensorflow; Neural Network; Prediction;

    Sammanfattning : In this thesis, a proof of concept of a digital twin of a type of reheating furnace, the walking beam furnace, is presented. It is created by using a machine learning concept called a neural network. LÄS MER

  5. 4. Carbon capture from reheating furnaces in the Swedish steel industry : evaluation of techno-economic feasibility

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Energivetenskap

    Författare :Anna Haglund; [2020]
    Nyckelord :Carbon capture; CCS; Swedish steel indusrty; post-combustion;

    Sammanfattning : The reduction of greenhouse gas emissions is important to keep climate change under control. One of the largest CO2 emitters of the Swedish industries is the steel industry. This is, among others, due to the need of heat treatments and reheating processes depending on high temperatures and fossil fuels. LÄS MER

  7. 5. A feasibility to electrify the combustion heated walking beam furnace : Applying induction and resistance heating

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Rikard Berger; Andreas Kopp; Harald Philipson; [2018]
    Nyckelord :Induction heating; Resistance heating; Steel reheating; Walking beam furnace; Steel slabs;

    Sammanfattning : The carbon footprint from the iron, steel and other metal sectors has become a problem both environmentally and economically. The purpose of this report is to propose a concept of an electrified reheat furnace for the steel industry in the making of sheet metal. The aim is to reduce the environmental impact from the steel industry. LÄS MER
