The project will be co-supervised by Prof Seetharaman, Royal Academy of Engineering / Tata Steel Research Chair in Low Carbon Materials Technologies, and an Industrial Scientist from TATA R&D.Â
This project intends to study the effects of drop-formation and evaluate the extent of refining that is carried out from metal drops as compared to the bulk slag.Â The IMPHOS project carried out by TATA-steel Europe was the first experimental study which captured samples in the bulk and emulsified phases as a function of time for different slag and metal compositions and temperatures. In this project a range of samples, collected by TATA-steel, will be characterized and the importance of drops will be elucidated. The working hypothesis to be tested will be:
- Refining occurs primarily through droplets as opposed to the bulk slag/metal interface.
- There is a critical flight time and size beyond which droplets will not completely equilibrate.
The work-plan would be as follows:
- Selection of a range(s) of samples to be characterized. This would have similar characteristics apart from the parameter to be investigated, e.g. time or height.
- Characterization in terms of bulk and metal chemistries and droplet size(s) and chemistries
- Comparison to P transfer models in literature. This would involve empirical correlations (e.g. Suito) and thermodynamic packages such as FACTSAGE.
- Identification of the cause of disagreement in and development of kinetic equations.
With the anticipated installment of a new high temperature scanning confocal laser microscope at WMG, real time experiment to follow a drop of given size immersed in a slag phase can be carried out to support and validate the developed equations.
Applicants should possess a first degree of at least a second class honours standard or the equivalent.
