Prof. Baojun Zhao (The University of Queensland)26/09/2018, 11:50Recycling of in-plant residuesOral PresentationHigh temperature experiments have been undertaken using equilibration, quenching and EPMA technique to characterise the phase equilibria of high Ti-containing slag systems. The experimental results have been presented in the form of pseudo-binary sections to show the effects of CaO, TiO2 and oxygen partial pressure on liquidus temperatures. The primary phases observed in the composition...Go to contribution page

Dr Saeed Ghali (Central Metallurgical Research & Development Institute (CMRDI))26/09/2018, 13:30Recycling of in-plant residuesOral PresentationIn Egypt, the crude steel production has increased significantly with higher growth rate in the past years of the 21th century. Furthermore, many mill steel companies have been established for steel processing. With the increase in steel production and steel processing, a large amount of waste materials (slag, dust and mill scale) are produced. Mall scale is one of these waste materials...Go to contribution page

Prof. Brian Monaghan (School of Mechanical, Materials, Mechatronic and Biomedical Engineering and ARC Research Hub for Australian Steel Manufacturing, University of Wollongong)26/09/2018, 13:50Recycling of in-plant residuesOral PresentationThe recycling of steel plant by-products is a key issue for all steelmakers. For these materials to be fully utilised without incurring environmental and economical penalties they need to be better understood with respect to their composition (morphology, phases and phase distribution). Research is being undertaken that aims to realise the value of steel plant by-products to the Australian...Go to contribution page

Mr Anton Andersson (Luleå University of Technology)26/09/2018, 14:10Recycling of in-plant residuesOral PresentationOre-based steelmaking generates a variety of residues including dusts, sludges, scales and slags. Recycling of these residues within the process or via other applications is essential for sustainable production from both environmental and economic aspects. In blast furnace (BF) ironmaking, the gas-cleaning equipment recovers the particles in the off-gas as BF dust and sludge. Traditionally,...Go to contribution page

Ms Katarina Lundkvist (Swerea MEFOS AB, Box 812, SE-97125 Luleå, Sweden)26/09/2018, 14:30Recycling of in-plant residuesOral PresentationAt SSAB Europe’s integrated steel plant in Luleå, Sweden, much effort is directed towards maximising the recycling of in-plant residues. As the blast furnace (BF) operates with a 100 % pellet burden, the main part of all dusts and sludge are recycled via a BF cold bonded briquette and by the BF-injection of its flue dust. However, BF sludge is not presently recycled due to concerns regarding...Go to contribution page

Dr Zhengjian Liu (University of Science and Technology Beijing)26/09/2018, 14:50Recycling of in-plant residuesOral PresentationCOREX shaft furnace dust contains large amounts of valuable elements, such as iron and carbon, and compared with blast furnace dust, it contains more metallic iron. Therefore, take appropriate process to recycle the COREX dust can further achieve efficient utilization of resources. The chemical composition, particle size distribution, microstructure and mineral composition of the dust were...Go to contribution page
