  1. 1. Construction and Evaluation of a Numerical Model for Heat Transfer in a Ladle During Pre-heating : A Finite Volume Approach to the Diffusion Equation using Julia

    University essay from KTH/Materialvetenskap

    Author : Gustaf Bjurstam; [2023]
    Keywords : Finite Volume Method; FVM; Diffusion equation; Ladle; Pre-heating; Baking; Heat equation; Heat transfer; Finita Volymmetoden; FVM; Diffusionsekvationen; Skänk; Förvärmning; Värmeledningsekvationen; Värmeledning;

    Abstract : Heat transfer is key to understanding many processes in engineering. At a steel mill heat transfer is absolutely crucial to understanding most of the processes. One such a process is the pre-heating of a freshly relined ladle. READ MORE

  2. 2. 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

  3. 3. Inoculant measurement with thermal analysis

    University essay from KTH/Materialvetenskap

    Author : Christopher Armstrong; [2020]
    Keywords : Thermal Analysis; Inoculation; Nucleation; Compacted Graphite Iron; CGI; Cast Iron; Material Properties;

    Abstract : Over time the level of inoculant will decrease due to fading and this needs to be compensated bymore additions of inoculant. When casting CGI400 at Scania a one-step method is used, and the inoculant additions are based on the last ladle from the previous oven. READ MORE

  4. 4. The Influence of Placement and Sintering Time of the Steel Ladle Filler-sand

    University essay from KTH/Materialvetenskap

    Author : Rana Tajik; Carl Holke; Johanna Nugin; [2018]
    Keywords : Filler-sand; Sintering time; Filler-sand placement; Filler-sand coverage; Strirring; Ladle free open; Skivtärningssand; sintringstid; sandplacering; spontan-öppning;

    Abstract : The filler-sand is a barrier between the slide gate system and the liquid metal in the steel ladle. During the casting process, the sintered sand should brake due to the ferrostatic pressure from the molten metal to initiate the teaming. This procedure is called a spontaneous opening in the casting context. READ MORE

  5. 5. Optimisation of the bottom stirring praxis in a LD-LBE converter : Investigations and tests on phosphorous removal, nitrogen as stirring gas, and slopping

    University essay from Uppsala universitet/Oorganisk kemi

    Author : José Aguirre Castillo; [2015]
    Keywords : LD; BOS; Bottom Stirring; Phosphorous; Steel making; Nitrogen;

    Abstract : The LD-process, called after the cities Linz and Donawitz, is used to convert pig iron into crude steel by blowing oxygen on top of the pig iron. A LD-LBE converter, Lance Bubbling Equilibrium, also stirs the melt trough a bottom stirring system. READ MORE
