  1. 1. Supervised Machine Learning Modeling in Secondary Metallurgy : Predicting the Liquid Steel Temperature After the Vacuum Treatment Step of the Vacuum Tank Degasser

    University essay from KTH/Materialvetenskap

    Author : Roberto Vita; [2022]
    Keywords : Industy 4.0; Machine Learning; Statistical Modeling; Temperature Prediction; Vacuum Tank Degasser; Vacuum Treatment Step.; Industri 4.0; Maskininlärning; Statistisk modellering; Temperaturförutsägelse; Vakuumbehandlingssteg; Vakuumtankavgasare;

    Abstract : In recent years the steelmaking industry has been subjected to continuous attempts to improve its production route. The main goals has been to increase the competitiveness and to reduce the environmental impact. The development of predictive models has therefore been of crucial importance in order to achieve such optimization. READ MORE

  3. 2. Dissolution of Cored Wire in Steel Melt : Optimization of Feeding Rate

    University essay from KTH/Materialvetenskap

    Author : Hagen Christian Hagens; [2022]
    Keywords : Cored wire injection · light alloy addition · feed rate optimization · inclusions modification · finite difference method;

    Abstract : Calcium treatment is an established operation in the production of steels. Most importantly, it serves to modify detrimental inclusions in the melt for improved castability and superior product properties. Due to calcium’s low melting point and high vapour pressure, its addition to liquid steel is challenging and yields are generally low. READ MORE

  4. 3. 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

  5. 4. Practical investigation of mixing phenomena by physical modelling : Scaling criteria applied for bottom gas-stirred water modelling of metallurgical vessels

    University essay from KTH/Materialvetenskap

    Author : Simon Garpenquist; Carl Erik Sebastian Lindfors; [2021]
    Keywords : Ladle furnace; Water model; Mixing time; Modified Froude number; Scaling criteria; Scaling factors; Skänkmetallurgi; Vattenmodell; Blandningstid; Froude s modifierade tal; Skalnings kriterier; Skalnings faktorer;

    Abstract : Gas stirring is currently the most commonly used method of homogenizing liquid steel in commercial processes. However, due to the harsh environment during the process, physical models built out of e.g. plexiglass have been used to easier understand the complex phenomenon occurring in the process. READ MORE

  6. 5. Investigation of the scale factor between full scale ladle furnace process and water models

    University essay from KTH/Materialvetenskap

    Author : Mathias Abelin; Håkan Blomkvist; [2020]
    Keywords : Ladle furnace; Modified Froude number; Two-phase gas plume; Water model scaling; Skänkmetallurgi; Froudes modifierade tal; Två-fas gasplym; Skalning av vattenmodell;

    Abstract : The ladle furnace process is an important process in the steel manufacturing industry. The purpose of this process is to optimize the composition of the elements in the melt as well as to homogenize the temperature in the liquid. It is common practice to model this process using smaller water models. READ MORE
