  2. 1. An Experimental Study to Improve the Casting Performance of Steel Grades Sensitive for Clogging

    Author : Jennie Svensson; Pär Jönsson; Voicu Brabie; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Preheating; Decarburization; RBM; Clogging; SEN; Plasma sprayed coating; CaTiO3; YSZ; Continuous casting; Pilot plant trials; Industrial plant trials; Clean steel; Tundish; Non-metallic inclusions; MISS; Materials Science and Engineering; Teknisk materialvetenskap; Steel Forming and Surface Engineering;

    Abstract : In this study, the goal is to optimize the process and to reduce the clogging tendency during the continuous casting process. The focus is on clogging when the refractory base material (RBM) in the SEN is in contact with the liquid steel. READ MORE

  4. 2. The Submerged Entry Nozzle : A Study of how to Reduce Decarburization and Clogging

    Author : Jennie Svensson; Pär Jönsson; Voicu Brabie; Johan Björkvall; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials Science and Engineering; Teknisk materialvetenskap; Steel Forming and Surface Engineering;

    Abstract : During continuous casting the submerged entry nozzle (SEN) is one of the critical points. This since sequence casting is favourable, clogging of the SEN results in fever sequences or aborted castings. In this study the preheating of SEN has been evaluated at different steel plants.

  5. 3. District Heating-driven Membrane Distillation for Water Purification in Industrial Applications

    Author : Daniel Minilu Woldemariam; Andrew Martin; Massimo Santarelli; Wojciech Kujawski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Distillation; District Heating; Wastewater Purification; Heat demand; Technoeconomy; Membrandestillation; Fjärrvärme; Avloppsvattenrening; Värme-behov; Teknoekonomi; Energy Technology; Energiteknik;

    Abstract : Domestic and industrial water demands are growing globally due to population growth and rapid economic development, placing increasing strains on water resources. Wastewater effluents generated from these and other activities impact the environment and are thus subject to tightening regulation. READ MORE

  6. 4. New methods for evaluation of tissue creping and the importance of coating, paper and adhesion

    Author : Jonna Boudreau; Christophe Barbier; Ulf Germgård; Sverker Albertsson; Robert Pelton; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue; creping; paper adhesion; Tissue paper; creping; paper adhesion; coating layer; adhesives; Yankee cylinder; crepe structure; wavelength measurements; Chemical Engineering; Kemiteknik;

    Abstract : The creping process and the conditions on the Yankee cylinder dryer are key factors in a tissue paper mill, and they therefore need to be kept under good control in order to maintain a high and uniform quality. To this end it would be valuable to be able to make on-line measurements of Yankee coating thickness as well as the crepe structure of the tissue paper. READ MORE

  7. 5. 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
