  1. 6. Some Study related to Refractory Waste Management in Sweden : A move towards a greener and sustainable Swedish steel industry

    University essay from KTH/Materialvetenskap

    Author : Surbhi Shivaji Jogdand; [2020]
    Keywords : Refractory waste; Swedish steel producers; Recyclers; MgO-C bricks; Fines; MgO; Carbon elimination; Agriculture industry; Eldfast avfall; svenska stålproducenter; Återvinnare; MgO-C-tegel; Böter; MgO; Koleliminering; Jordbruksindustri.;

    Abstract : Decades  ago,  1  ton  of  steel  required  80  kg  of  refractory  material.  While  the  scenario  has completely changed over the years. Today, 1 ton of steel needs approximately 11 kg of refractory material   depending   on   the   steelworks. READ MORE

  3. 7. Secondary Steel Metallurgy Slag Design and MgO-C Refractory Implications : Theoretical and Practical Considerations

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

    Author : Hellgren Simon; [2019]
    Keywords : MgO-C; CaO-SiO2-Al2O3-MgO; Slag Design; Refractory Wear;

    Abstract : MgO-C based refractory materials, often used in secondary steel making, are exposed to variouswear mechanisms in its application. The wear could be divided into oxidative, chemical andabrasive categories, all behaving differently and all being influenced by different factors. READ MORE

  4. 8. Development of method for processing brittle-hard materials using Laser Metal Deposition (LMD)

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Alejandro Simó Vesperinas; [2018]
    Keywords : Additive Manufacturing AM ; Laser Metal Deposition LMD ; Direct Metal Deposition DMD ; High-temperature materials; Mo-Si-B alloy; Residual stress; Cracks;

    Abstract : New materials capable of operating at ultra-high temperatures in gas turbine engines are highly desired. Materials such as silicides of refractory metals present great potential to substitute single crystal nickel-based superalloys. READ MORE

  5. 9. Titanium vacancy diffusion in TiN via non-equilibrium ab initio molecular dynamics

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Davide Gambino; [2016]
    Keywords : Titanium nitride; Ti monovacancy migration; Non-equilibrium ab initio molecular dynamics; Color diffusion algorithm; Statistics for stochastic events;

    Abstract : Transition metal nitrides (TMNs) refractory ceramic materials are  widely employed as wear-resistant protective coatings in industrial machining as well as diffusion barriers inhibiting migration of metal impurities from the interconnects to the semiconducting region of electronic devices. TiN is the prototype of this class of materials and the most studied among TMNs. READ MORE

  6. 10. Exposure studies of refractory materials for biomass gasification

    University essay from Institutionen för tillämpad fysik och elektronik

    Author : Markus Carlborg; [2013]
    Keywords : Gasification; biomass; high alumina refractories; alkali; slag;

    Abstract : Gasification is a technology mostly used to convert fossil feedstock to syngas. Biomass could be used as a feedstock instead but that puts different demands on, among other things, the materials in these reactors. READ MORE
