Multiscale modelling of the transport phenomena of liquid iron and slag in ironmaking blast furnace. Blast furnace ironmaking is a key operation in the steel industry which, with an annual turnover around $11 billion, is a significant manufacturing sector in Australia. This project, focused on the behaviour of liquid iron and slag, can generate computer models that can reliably describe the complicated multiphase flow and thermochemical processes in the furnace. The implementation of the resulta ....Multiscale modelling of the transport phenomena of liquid iron and slag in ironmaking blast furnace. Blast furnace ironmaking is a key operation in the steel industry which, with an annual turnover around $11 billion, is a significant manufacturing sector in Australia. This project, focused on the behaviour of liquid iron and slag, can generate computer models that can reliably describe the complicated multiphase flow and thermochemical processes in the furnace. The implementation of the resultant models and the new understanding should lead to long life campaigns, better operational control, decreased fuel consumption, improved productivity and reduced environmental impact. This, together with the proposed research training, is important to the development of Australia's competitive steel industry.Read moreRead less

Free Surface Instability and Gas Entrainment during Blast Furnace Drainage. Iron and Steelmaking operations have underpinned Australia's industry base for many years. To remain competitive in a global market BHP has undertaken considerable research and development to constantly improve process performance. An area of on-going concern is the unexpected release of gas during Blast Furnace drainage resulting in hazardous conditions for the operators and overall loss of production. This project aims ....Free Surface Instability and Gas Entrainment during Blast Furnace Drainage. Iron and Steelmaking operations have underpinned Australia's industry base for many years. To remain competitive in a global market BHP has undertaken considerable research and development to constantly improve process performance. An area of on-going concern is the unexpected release of gas during Blast Furnace drainage resulting in hazardous conditions for the operators and overall loss of production. This project aims to identify the causes of gas release and to devise operational strategies and design modifications to prevent this occurrence. Once implemented the outcomes of the research will be a more stable operation leading to increased production and less environmental emissions.Read moreRead less
Inter-metallic Inclusion Reduction in Continuous Metallic Coating. The ZINCALUMER coating process is a core business of BlueScope Steel. Operational and quality issues are being experienced due to inter-metallic particles in the liquid metal bath. The particles cause defects in the metal coating and agglomerate, resulting in periodic shutdowns to remove the dross. Both of these factors impact significantly on the profitability of the operation. In this project a new strategy is being investigate ....Inter-metallic Inclusion Reduction in Continuous Metallic Coating. The ZINCALUMER coating process is a core business of BlueScope Steel. Operational and quality issues are being experienced due to inter-metallic particles in the liquid metal bath. The particles cause defects in the metal coating and agglomerate, resulting in periodic shutdowns to remove the dross. Both of these factors impact significantly on the profitability of the operation. In this project a new strategy is being investigated, whereby the fluid mechanics and heat transfer mechanisms within the bath will allow inter-metallic particles to be continuously removed in the metal coating before they reach the critical size that adversely affects product quality. This will also reduce dross accumulation, thereby reducing shutdown time.Read moreRead less
