Magnetically impelled arc butt (MIAB) joining is a non-traditional manufacturing process for tubular steel components. Parameter selection and tuning have to date been experimentally determined via exhaustive trial-and-error techniques. Therefore the full capabilities of the process have not yet been realised.

This can contribute in further enhancing Australia's position as a significant producer and exporter of aluminium and associated products. The project will generate scientific data on refractory/metal interactions and establish influence of non-wetting agents in improving refractory performance against metal attack. Read moreRead less
A Fundamental Investigation of the Thermoplastic Behaviour and Porous Structural Evolution of Coke and Char Particles. During heating, solid fuel particles undergo complex physical changes resulting in sophisticated structures in the residual material (coke and char) which influence the operational performance of these materials in ironmaking and power generation processes.

During heating, solid fuel particles undergo complex physical changes resulting in sophisticated structures in the residual material (coke and char) which influence the operational performance of these materials in ironmaking and power generation processes. The mechanistic understanding of the evolution of physical structure and the coupled role of gas evolution has not been well established. An interpretive and predictive mechanism to describe the process will be developed through experimental observations and mathematical modelling. The project will provide fundamental new insights and understanding of operational issues concerning the complex behaviour of solid fuel residues in coal based industrial processes.Read moreRead less
New Generation Pipeline and Q&T Plate Steels. If successful, the progressive reformulation of the alloy design of a new family of steels would enhance their properties, greatly reduce the complexity of manufacture, ensure more efficient steelmaking production practices and enable the full capacity of the domestic pipe mills and plate manufacturing facilities to be realised. This innovative and new approach opens up opportunities for market growth and export potential in areas of fundamental impo ....New Generation Pipeline and Q&T Plate Steels.

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
