Gilles KASS (Paul Wurth S.A.)25/09/2018, 10:45SinteringOral PresentationCooling of hot sinter involves the release of significant quantities of energy and is a source of fugitive dust emissions. The increasing pressure that steel producers are facing in regard to energy consumption, reduction of CO2 and air emissions, require new processes and technologies to maximise energy recovery of the sinter cooling and to lower its environmental impact. Paul Wurth has been...Go to contribution page

Mr Ahmadreza Amini (Department of Materials Process Engineering, Graduate School of Engineering, Kyushu University, Japan)25/09/2018, 11:25CO2 reduction and energy savingOral PresentationRecently, reduction of CO2 emission and also energy conservation in ironmaking process are serious concerns which persuaded the researchers to look for a cleaner and a more efficient method for iron production. Microwave heating has been considered as a new heating method for iron ore reduction which could decrease the required carbonaceous materials for iron production. However, it...Go to contribution page

75. APPLIED FUNDAMENTAL RESEARCH OF FERRO-COKE PRODUCTION BY THE STAMPED CHARGING COKEMAKING PROCESSProf. Xuegong BI (State Key Laboratory for Refractory Materials and Metallurgy, Wuhan University of Science and Technology)25/09/2018, 11:45CO2 reduction and energy savingOral PresentationFerro-coke is a highly reactive coke and considered a promising advanced burden material for blast furnace ironmaking due to a potential of decreasing RAR and CO2 emission. The essential reason is it reacts with CO2 in BF gases at lower temperatures, which is resulted in by the catalytic effect of metallic iron, and leads to a lower temperature of the thermal reserve zone. However, since iron...Go to contribution page

Mr Anand Kumar AGRAWAL (PaulWurth)25/09/2018, 14:30CO2 reduction and energy savingOral PresentationThe iron and steel industry is a source of industrial CO2 emissions. The BF-BOF route of iron and steel making is considered as the most successful and economic route, hence widely employed for the iron and steel production. To comply with the targets set by the latest “conference of the parties” (COP) for climate change significant additional effort is required to achieve the target CO2...Go to contribution page

Dr Jia-Shyan Shiau (China Steel Corporation)25/09/2018, 14:50SinteringOral PresentationIn operational practice of the iron ore sintering machine, the increasing air leakage ratio will cause the higher electricity consumption of the suction fan, the higher solid fuel rate, the lower sinter productivity, and the worse sinter quality. In general, more than 50% of the leakage occurs at the pallets themselves and the interfaces between the pallets and the wind boxes. Basically, the...Go to contribution page

Prof. Chuan Wang (Swerea MEFOS)25/09/2018, 15:10CO2 reduction and energy savingOral PresentationWithin the integrated steel plant, the blast furnace BF is the most energy intensive process with significant amount of CO2 emission. Switching of fossil fuels to biomass offers an alternative for the natural resources reservation and climate change mitigation. In recent years, lots of efforts have been putting on developing biomass for BF’s utilization, especially in regions with abundant...Go to contribution page

Mr Ka Wing Ng (Natural Resources Canada)25/09/2018, 15:30CO2 reduction and energy savingOral PresentationSubstitution of pulverized coal injection by solid biocarbon fuel has the potential to achieve substantial reduction in GHG emissions from blast furnace ironmaking. A techno-economic model was developed to evaluate the value-in-use of solid biocarbon to facilitate the selection of solid biocarbon for replacement of pulverized coal injection. The value-in-use of solid biocarbon is strongly...Go to contribution page
