  2. 1. An Experimental and Numerical Study of the Heat Flow in the Blast Furnace Hearth

    Author : Maria Swartling; Pär Jönsson; Henrik Saxén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blast furnace; hearth; heat transfer; model; experimental; numerical; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : This study has focused on determining the heat flows in a production blast furnace hearth. This part of the blast furnace is exposed to high temperatures. In order to increase the campaign length of the lining an improved knowledge of heat flows are necessary. Thus, it has been studied both experimentally and numerically by heat transfer modeling.

  4. 2. A Study of the Heat Flow in the Blast Furnace Hearth Lining

    Author : Maria Swartling; Pär G. Jönsson; Xuegong Bi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blast furnace; heat transfer; mathematical model; experimental; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : The aim of the present thesis was to study the heat flows in the blast furnace hearth lining by experimental measurements and numerical modeling. Thermocouple data from an operating furnace have been used throughout the work, to verify results and to develop methodologies to use the results in further studies. READ MORE

  5. 3. Some aspects on the reduction of olivine pellets in laboratory scale and in an experimental blast furnace

    Author : Jerker Sterneland; KTH; []
    Keywords : Olivine; pellets; pellet testing; reduction softening melting; MPBO; blast furnace; reduction; quenching; dissection; coating; sticking; coated pellets;

    Abstract : The reduction behaviour of the olivine iron ore pellet MPBOwas studied in laboratory scale at KTH as well as in the LKABexperimental blast furnace. Initially, a newreduction-under-load, or so-called reduction/softening/melting,test equipment was developed. READ MORE

  6. 4. Mineral Reactions and Slag Formation During Reduction of Olivine Blast Furnace Pellets

    Author : Elin Ryösä; Hans Annersten; Kyösti Heinänen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; olivine; iron ore pellets; blast furnace; reduction; alkali; coating; slag formation; Earth sciences; Geovetenskap;

    Abstract : The present work focuses on mineral reactions and slag formation of LKAB olivine iron ore pellets (MPBO) subjected to reducing conditions in the LKAB experimental blast furnace (EBF). The emphasis is on olivine reactions with surrounding iron oxides. Many factors influence the olivine behaviour. READ MORE

  7. 5. Contributions to the use of designed experiments in continuous processes : a study of blast furnace experiments

    Author : Erik Vanhatalo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology Management;

    Abstract : Design of Experiments (DoE) contains techniques, such as factorial designs, that help experimenters maximize the information output from conducted experiments and minimize the amount of experimental work required to reach statistically significant results. The use of DoE in industrial processes is frequently and thoroughly described in literature. READ MORE
