  2. 11. Sustainable Recycling of Spent Lithium-ion Batteries : An In-situ Approach for Recovery and Alloying of Valuable Metals

    Author : Safoura Babanejad; Hesham Ahmed; Charlotte Andersson; Ari Jokilaakso; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Li-ion battery; black mass; Recycling; Pyrometallurgy; modeling; Process Metallurgy; Processmetallurgi;

    Abstract : A large number of Li-ion batteries used today will reach their End-Of-Life (EOL) in a few years. After their EOL, the recovery of their precious elements is required. By applying physical separation, a fraction with fine particle size is left behind which is known as Black Mass (BM). READ MORE

  4. 12. A Study of the Swirling Flow Pattern when Using TurboSwirl in the Casting Process

    Author : Haitong Bai; Mikael Ersson; Pär Jönsson; Yogeshwar Sahai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow pattern; swirling flow; TurboSwirl; CFD; turbulence models; water model; flödesmönster; roterandeflöde; TurboSwirl; CFD; turbulensmodeller; vattenmodell; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The use of a swirling flow can provide a more uniform velocity distribution and a calmer filling condition according to previous studies of both ingot and continuous casting processes of steel. However, the existing swirling flow generation methods developed in last decades all have some limitations. READ MORE

  5. 13. Three Dimensional Determinations of Inclusions in Ferroalloys and Steel Samples

    Author : Yanyan Bi; Andrey Karasev; Chris Pistorius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Three dimensional; Ferroalloy; Inclusion; Spinel inclusion; T hermodynamic calculation; REM clusters; Formation mechanism; Statistical analysis; Maximum size;

    Abstract : As the requirements on material properties increase, there has been a demand on an additional knowledge on the effect of impurities in the ferroalloyson the steel cleanness. Thus, the number, morphology, size and composition of inclusions in sixdifferent ferroalloys (FeTi, FeNb, FeSi,SiMn, LC and HC FeCr) were investigatedin this study. READ MORE
