  1. 6. Developing a supervised machine learning model for an optimised aluminium addition based on historical data analytics, for clean steelmaking

    University essay from KTH/Materialvetenskap

    Author : Arun Kumar Thakur; [2022]
    Keywords : Clean steelmaking; Data analytics; De-oxidation; Machine learning; Ren ståltillverkning; Dataanalys; Deoxidation; Maskininlärning;

    Abstract : De-oxidation is an important process in clean steelmaking. Al (Aluminium) is mainly used as de-oxidant and controls the final oxygen content and impact the sulphur removal in steel. Adding optimum amount of Al is critical for steel cleanliness and to reduce cost. READ MORE

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

    University essay from KTH/Materialvetenskap

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

    Abstract : 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”. READ MORE

  4. 8. Cost Efficient Scrap Metal Sourcing

    University essay from Lunds universitet/Teknisk logistik

    Author : Sophia Sandström; Sofia Ivarsson; [2022]
    Keywords : Scrap sourcing; Scrap logistics; European scrap market; Sea freight strategies; Bulk shipping; Technology and Engineering;

    Abstract : The steel industry in Sweden is responsible for 10% of the annual Swedish CO2 emissions. As a way to abate this sector, H2 Green Steel are establishing a new green steel production site in Boden. Their way of producing steel, through the EAF route and by using hydrogen-reduced DRI will reduce the CO2 emissions by over 90%. READ MORE

  5. 9. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Jijesh Rajan; [2022]
    Keywords : Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

    Abstract : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. READ MORE

  6. 10. 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
