  1. 21. Pitting Corrosion Evaluation of Post-Weld Cleaning Methods for Stainless Steel Welds

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jimmy Holgersson; Klara Trydell; [2019]
    Keywords : ;

    Abstract : Welding stainless steel creates an oxide film, heat tint, on the surface and around the joint. It disrupts passivation and influence the corrosion resistance for the material. The result is often a decrease in pitting corrosion resistance for the joint and surrounding area. The heat tint is therefore commonly removed by post weld cleaning. READ MORE

  4. 23. Evaluation of alternative methods forquality control of Tungsten Carbide : An evaluation of four different particle measuring techniques

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Markus Näsman; [2019]
    Keywords : Particle measurement; Quality control; Tungsten Carbide; Hard metal; Fisher Sub-Sieve Sizer; Brunauer Emmett Teller; X-ray Diffraction; Laser Diffraction;

    Abstract : The purpose of this study was to evaluate four different measuring methods as potentialquality control tests for Tungsten Carbide (WC) raw material used in the hard metalmanufacturing at Seco Tools Fagersta. This was warranted as the current quality testcalled the HcK test, is very time consuming and the results provided that are used formilling time calculations cannot be relied on. READ MORE

    Abstract : The Swedish metal company Boliden has since the early 20th century been mining deposits in the mining field commonly referred to as the Skelleftefield in northern Sweden. The youngest of the active mines is the Kankberg mine which is an underground mine whose reserve contains gold and tellurium. READ MORE

  6. 25. Alkali Circulation in the Blast Furnace - Process Correlations and Counter Measures

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Joel Carlsson; [2018]
    Keywords : Alkali; coke; experimental blast furnace; top gas; mass spectrometry; multivariate analysis;

    Abstract : In blast furnace ironmaking one major challenge is to control and measure the alkalis circulating and accumulating in the blast furnace (BF). Alkali enter the BF with the primary raw material and will form a cycle where it is first reduced to metal at the lower parts forming gas. READ MORE
