    1. 76. SEARCH FOR AN ALTERNATIVE PROCESSING OF MAGNETITE CONCENTRATE CONTAINING OXIDES OF VANADIUM AND TITANIUM
      Dr Yury Kapelyushin (South Ural State National Research University)
      27/09/2018, 08:30
      Direct reduction
      Oral Presentation
      Abstract An existing scheme of vanadium production from low-titanium magnetite concentrates is energy-consuming and associated with loss of valuable elements, e.g. titanium. The present work investigates the possibility of obtaining products, which are different from the processing using the conventional technological scheme, for further development of an energy-efficient and wasteless...

    2. 298. LABORATORY STUDY OF REDUCTION KINETICS IN A DRI SHAFT FURNACE
      Mr Mahdi Farahani (ArcelorMittal.USA)
      27/09/2018, 08:50
      Direct reduction
      Oral Presentation
      This article presents a novel experimental procedure that simulates the complicated counter-current DR shaft process. This lab test is recently developed in ArcelorMittal Global R&D and shows good correlation with actual direct reduction process. The method provides a unique tool to study the impact of DR plant operation parameters in the laboratory scale, and enables the study of raw...

    3. 109. KINETIC ANALYSIS OF CARBON FIBER DEPOSITION ON CATALYST IRON IN CO-H2 MIXTURE GAS
      Mr Kazuto NISHIHIRO (Department of Materials Process Engineering, Graduate School of Engineering, Kyushu University, Japan)
      27/09/2018, 09:10
      Direct reduction
      Oral Presentation
      CO-H2 mixture gas is often used for gas-based DRI process where carbon deposition reaction and Fe3C metal dusting play serious roles for a stable reduction operation. Fe3C decomposition leads to the formation of iron particles which is a catalyst for carbon fiber deposition. Because of the parallel occurrence of these reactions, kinetic analysis of them would...

    4. 282. REDUCTION OF TITANOHEMATITE PELLETS BY HYDROGEN GAS
      Mr Ao Zhang (Robinson Research Institute, Victoria University of Wellington)
      27/09/2018, 09:30
      Direct reduction
      Oral Presentation
      Ironsand is a potential cheap source of iron with possible other values such as titania and vanadium oxide. Direct reduction is regarded as one of the promising processes to deal with ironsand in both an economically and environmentally sustainable manner. In this study, the reduction characteristics of pelletised ironsand ore by hydrogen gas were investigated. The pelletising and sintering of...

    5. 198. EXPERIMENTAL STUDY AND FEASIBILITY ANALYSIS ON FLASH REDUCTION IRON MAKING PROCESS
      Dr Lei Guo (University of Science and Technology Beijing)
      27/09/2018, 10:20
      Direct reduction
      Oral Presentation
      Due to the very fast reduction rate and its possibility to get rid of coke and other technical advantages the flash reduction iron making process has drawn a lot of concern by many experts and scholars in recent years. According to relative literatures, the derivative process of flash reduction of iron ore is analyzed. The development of the flash reduction iron making process at home and...

    6. 293. SUSTAINABLE DECREASE OF CO2 EMISSIONS IN THE STEELMAKING INDUSTRY BY MEANS OF THE ENERGIRON DIRECT REDUCTION TECHNOLOGY
      Dario Pauluzzi (Danieli & Officine Meccaniche)
      27/09/2018, 10:40
      Direct reduction
      Oral Presentation
      Compared to the traditional Blast Furnace – Basic Oxygen Furnace way of producing steel, more than 50% of CO2 emissions can saved if steel is produced by means of the Energiron Direct Reduction – Electric Arc Furnace way. This target is achieved partly thanks to the use of reducing sources cleaner than coal, and partly thanks to the selective capture of up to 90% of the CO2 produced, that can...

    7. 223. DIRECT REDUCTION: TRANSITION FROM NATURAL GAS TO HYDROGEN?
      Prof. Marc Hölling (Hamburg University of Applied Science, Dept. of Process Engineering)
      27/09/2018, 11:00
      Direct reduction
      Oral Presentation
      The future of the European steel industry demands solutions for carbon free production routes to fulfil the challenging goals of today‘s climate policies. In terms of CO2-emissions, the reduction process is the most relevant process – be it in a blast furnace or in a direct reduction plant. One solution to this issue could be the transition from fossil-based to hydrogen-based reduction of iron...

    8. 285. FURTHER OPPORTUNITIES OF COMPETITIVENESS IMPROVEMENTS FOR DIRECT REDUCTION PLANTS
      Mr Robert Millner (Primetals Technologies Austria GmbH)
      27/09/2018, 11:20
      Direct reduction
      Oral Presentation
      Midrex and Primetals Technologies have successfully completed their latest HBI projects for voestalpine Texas LLC/USA and LGOK/Russia. This paper discusses some further possibilities for improvements of Direct reduction plants in order to increase the plant competitiveness and/or flexibility. Such plant improvements have been either already implemented in the latest projects for the first...
