  2. 16. Cracking during Continuous Casting of Steels : Analysis tools and procedures to identify their causes on microalloyed steel slabs

    Author : Rosa Maria Pineda Huitron; Esa Vuorinen; Pavel Ernesto Ramí­rez López; Maria Begoña Santillana; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transverse corner cracks; Continuous Casting; Microalloyes steels; Secondary cooling; Cooling curves; Crack susceptibility; Materialteknik; Engineering Materials;

    Abstract : Transverse corner cracks are one of the most common but complex defects formed in microalloyed steels during continuous casting (CC). Such cracks are detrimental because it leads to a loss in productivity with a great impact on environment, energy and economics for several steel making companies all over the world. READ MORE

  4. 17. Lubrication of conformal contacts with surface texturing

    Author : Samuel Cupillard; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : Conformal contacts like those found in journal or inclined slider bearings are widely encountered in various types of machines from small engines to large turbines. These contacts involve convergent gaps that are used to separate the surfaces in relative motion and generate pressure in the lubricant film. READ MORE

  5. 18. Optical Characterization of Solar Collectors form Outdoor Measurements

    Author : Anna Helgesson; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Due to high installation costs and relatively low output, the active use of solar energy is limited. The output from a collector can be improved e.g. by using a selective absorber, AR-treated cover glass or transparent insulation. READ MORE
