  1. 1. 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. 2. CFD analyses of the gas flow inside the vessel of a hot isostatic press

    University essay from KTH/Kraft- och värmeteknologi

    Author : Andreas Åkerberg; [2012]
    Keywords : CFD; hot isostatic press; computational fluid dynamics; numerical methods; furnace; pressurized gas; vessel; rapid cooling;

    Abstract : Hot isostatic pressing (HIP) is a thermal treatment method that is used to consolidate, densify or bondcomponents and materials. Argon gas is commonly used as the pressure medium and is isostaticallyapplied to the material with an excess pressure of 500-2000 bar and a temperature of 500-2200oC. READ MORE

  4. 3. 3D study of non-metallic inclusions by EEmethod and use of statistics for the estimationof largest size inclusions in tool steel.

    University essay from KTH/Materialvetenskap

    Author : Meer Safa; [2010]
    Keywords : Tool Steel; Electrolytic Extraction; Vacuum degassing; Non-metallic inclusions; Induction stirring; Argon flow rate; Ladle age; Extreme value analysis.;

    Abstract : The control of non-metallic inclusions is very important for the improvement of performance during the application of tool steel. This present study was performed to see the effect of changing of some process parameters during the vacuum degassing of the melt and how these changing parameters affects the characteristics of inclusions in tool steel.

  5. 4. Study of Lignocellulosic Biomass Pyrolysis : State of the Art and Modelling

    University essay from KTH/Industriell ekologi

    Author : Ana Rengel; [2007]
    Keywords : ;

    Abstract : Fast pyrolysis is a technology that is emerging as an alternative to transform organic and fossil materials into a new form of energy, mainly the so-called bio-oil. Until nowadays, examples of raw materials that have been experimented are wood and forest residues, bagasses as well as straw and agro-residues. READ MORE
