  1. 16. TM-rolling of heavy plate and roll wear

    Författare :Mikael Jonsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik; Heavy plate;

    Sammanfattning : The heavy plate rolling process needs accurate predictions of the process parameters. The plate thickness, flatness and rolling stability are of this direct influenced as well as the productivity. Therefore, careful calculation of the process parameters and pass schedules is necessary. LÄS MER

  3. 17. Thermo-Mechanical Modelling of Hot Strip Coil Cooling Process

    Författare :Mats Karlberg; Daniel Berglund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : In hot rolled steel strip production the processed material are after the cooling section coiled into coils. Coils do normally weigh around 20 tons with a diameter of 2 m and heights equal to the strip width e.g. 0. LÄS MER

  4. 18. Laser welding : energy redistribution and weld geometry

    Författare :Conny Lampa; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : Over the past few years laser welding has developed into a process which has a wide range of application over a number of industries. Industrial growth in this area has been stimulated by improvements in production rates and quality but technologically the process is still not fully understood. LÄS MER

  5. 19. Fiber push-out testing of sapphire fiber alumina matrix composites

    Författare :David Le Pagne; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : A current area of international research and development concerns composite materials consisting of oxides reinforced with continuous oxide fibers. These materials have an inherent resistance to oxidation and therefore have potential as structural materials for applications at extremely high temperatures. LÄS MER
