    1. 161. COMPARISON OF BLAST FURNACE OPERATION MODES IN THE WORLD
      Hans-Bodo Lüngen (Director Technology VDEh)
      25/09/2018, 09:05
      Keynote
      Oral Presentation
      The blast furnace is worldwide the dominant metallic product supplier for crude steel production. It has reached an extreme high technological standard with large efficiency and low reductant rates. Independently from the fact that the blast furnace has nearly reached its theoretical minimum in energy consumption it enables the operators a wide range of operation modes with a high flexibility....

    2. 252. RECENT RESEARCH＆DEVELOPMENT TOPICS OF IRON-MAKING TECHNOLOGIES IN NSSMC
      Dr Koji Saito (Nippon Steel & Sumitomo Metals Corporation)
      25/09/2018, 09:35
      Keynote
      Oral Presentation
      The last decade was a turbulent for the steel industry. The reorganization of steel industry across borders has progressed and the increased demand for steel products has made the price of raw materials such as iron ore and metallurgical coal more volatile than ever. Ironmaking technology division in NSSMC has been exposed to global competition and has tried to cope with these changes and to...

    3. 18. PRESENT STATUS AND FUTURE PERSPECTIVE OF IRONMAING IN CHINA
      Prof. Tianjun Yang (University of Science and Technology Beijing)
      25/09/2018, 13:30
      Blast furnace ironmaking
      Oral Presentation
      During last few years, iron production in China was kept at about 700 million tons annually, which was totally produced from BF process. At same time, a lot of mini BFs have been eliminated, and many big BFs have been built up and put into operation. There are 23 BFs with inner volume equal or over 4000m3. Both sinter machines and pellet facilities have been enlarged and upgraded...

    4. 134. Modeling inner phenomena of self-reducing agglomerates under external inert gas atmosphere
      Prof. Jose Adilson Castro (Federal Fluminense University)
      25/09/2018, 13:50
      Keynote
      Oral Presentation
      The self-reducing phenomena has been explored with the aim of improving the reducing velocity of agglomerates during hot metal production. The inner phenomena taking place in the agglomerates, however, are still controversial and further studies are demanded. In this paper we proposed a detailed mechanism taking place within the agglomerates during the solid-gas self-reducing step. In order to...

    5. 206. UNDERSTANDING COKE FORMATION AND QUALITY BY ANALYSIS OF PHYSICO-CHEMICAL PROCESSES
      Dr David Jenkins (University of Newcastle)
      26/09/2018, 08:00
      Keynote
      Oral Presentation
      The conversion of coal into coke is a complex process, involving interrelated phenomena occurring simultaneously. These include heat transfer, gas evolution, softening and resolidification, evaporation and condensation, bubble growth and coalescence, gas transport, shrinkage and fissuring. Moreover, a key aspect of coke quality is its (cold and hot) strength as well as its reactivity. ...

    6. 234. FOOTPRINTS FOR THE FUTURE OF COMMERCIAL FINEX PLANTS
      Dr Sang-Ho Yi (POSCO)
      26/09/2018, 08:20
      Smelting reduction
      Oral Presentation
      FINEX® is an alternative iron making process to the blast furnace (BF) route and it is based on the direct use of iron ore fines and non-coking coal, which gives operational flexibility, cost competitiveness and environmental benefits compared to the conventional BF route. Continuous improvements are carried out to increase the process efficiency, including the latest developments of the...
