  2. 1. A study of micro-particles in the dust and melt at different stages of iron and steelmaking

    Author : Muhammad Nabeel; Andrey Karasev; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle size distribution; ironmaking; iron ore pellets; dust generation; mechanical wear; friction; reduction; REM clusters; Electrolytic extraction; cluster size distribution; growth mechanism; collisions; statistical analysis.; Teknisk materialvetenskap; Materials Science and Engineering; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The dust particles generated due to mechanical wear of iron ore pellets and clusters formed in molten stainless steel alloyed with rare earth metals (REM) are considered in this study. Firstly, the influence of the characteristics of iron ore pellets, applied load on a pellet bed and partial reduction of the pellets on the size distribution of the generated dust was investigated.

  4. 2. Control of Alloy Composition and Evaluation of Macro Inclusions during Alloy Making

    Author : Yuichi Kanbe; Du Sichen; Leiv Kolbeinsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slag metal reaction; equilibrium; kinetics; largest inclusion; statistics of extreme values; electrolytic extraction; cross section; inclusion morphology; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : In order to obtain a good performance and predict the properties of alloys, it is necessary to control the contents of alloying elements and to evaluate a largest inclusion in the product. Thus, improved techniques for both control of alloy elements and evaluation of the large inclusion in products will enable us to provide better qualities of the final products. READ MORE

  5. 3. Advanced cranial navigation

    Author : Simon Skyrman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Neurosurgery is performed with extremely low margins of error. Surgical inaccuracy may have disastrous consequences. The overall aim of this thesis was to improve accuracy in cranial neurosurgical procedures by the application of new technical aids. READ MORE
