  2. 21. An Experimental Study of a Liquid Steel Sampling Process

    Author : Ola Ericsson; Andrey Karasev; Pär Jönsson; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid steel sampling; inclusion characteristics; sampling conditions; sample homogeneity.; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : During the steelmaking process samples are taken from the liquid steel, mainly to assess the chemical composition of the steel. Recently, methods for rapid determination of inclusion characteristics (size and composition) have progressed to the level where they can be implemented in process control. READ MORE

  4. 22. Electron beam-powder bed fusion of Alloy 718 : Effect of process parameters on microstructure evolution

    Author : Paria Karimi Neghlani; Joel Andersson; Joakim Ålgårdh; Iain Todd; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Electron beam-powder bed fusion; Microstructure evolution; Microstructure tailoring; Process understanding; Alloy 718; Production Technology; Produktionsteknik;

    Abstract : Additive manufacturing (AM) is the technology of building 3D parts through layer-by-layer addition of material. Of the different types of AM techniques, electron beam-powder bed fusion (EB-PBF) has been used in this study. EB-PBF can build parts by melting metallic powders using an electron beam as the energy source. READ MORE

  5. 23. Stabilization-solidification of high water content dredged sediment : Strength, compressibility and durability evaluations

    Author : Gregory Makusa; Kauko Kujala; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. READ MORE

  7. 25. Theoretical magnetohydrodynamic and solidification studies of continuous strip casting

    Author : Hans B. Löfgren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : The continuous casting of steel strips has been under investigation and development for several decades. The aim of this development is to be able to cast steel strips in a thickness range from 1 to 10 mm. Today, there are basically two such methods: the single-belt caster and the twin-roll caster.
