Using Rapid Alloy Prototyping to understand the effects of Tramp elements in increased Scrap Steel Recycling

Key Information

In Tata Steel’s integrated steel plant in Port Talbot, melts are produced at a scale of 300t. For product development – going through numerous industrial trial iterations of 300t melts is economically unfeasible, therefore the majority of product development iterations are first carried out on pilot-scale trials of 25kg. After isolating a sensible alloying route, trials are progressed to full-scale trials.

The rapid alloy prototyping (RAP) technique available in MACH1 in Swansea University is a 20g induction melting route to create synthetic steels. The advantage of using this type of RAP is that numerous iterations of incremental alloying compositions can be produced to screen and down-select winning compositions and optimise processing windows for subsequent use in 25kg & 300t full-scale trials. This presents the opportunity of not only improving the understanding of the alloy systems but also to increase the ‘right first time’ developments.  

One of the challenges is to develop testing techniques on RAP samples (composition, microstructure, mechanical properties) which are representative of the same compositions as-processed through larger scale and industrial-scale routes.

One of the applications of RAP is to improve the understanding in synergistic effects of tramp elements in various steel grades and associated applications. By systematically adding the levels of tramp elements one can de-convolute their effect on the alloy systems.

This is important because, on average, every half hour 60t of scrap steel are used as coolant in the Basic Oxygen Steelmaking converter in Port Talbot – leading to the introduction of tramp elements in the steel. Using more scrap in steel presents a cost saving of ~£20 per tonne thus the output of this work may result in significant financial benefits to Tata Steel. Increasing the use of scrap also has significant environmental benefits as every tonne of recycled steel reduces ore consumption by 1.5 tonnes and reduces CO2 emissions by 80%.

Project Aims

1.       To grasp through-process understanding on plant and the ins and outs of RAP

2.       Develop simplified RAP characterisation techniques which give sensible trends on 20g samples and are benchmarked against 25kg and 300t routes

3.       Understand the effects of various tramp alloying elements on exemplar alloys

4.       Challenge the current tramp element limits in secondary steelmaking

Suitable candidate 

The candidate will have a degree in Materials Science, Physics, Chemistry or other Engineering/Science discipline and have excellent communication skills both verbal & written.

Must have own means of transport and will be expected to spend some time in various operational sites in order to broaden horizons and improve understanding of the Tata Steel product range.
