Participants were tasked to produce a grade of steel meeting technical requirements at the lowest cost per tonne with carbon footprint requirements. The simulation used a grade of steel specifically designed for steelChallenge-17. Competitors could undertake ‘runs’ of the simulation during the 24-hour competition period. A ‘run’ was concluded when the simulation had completed the set time, the result had been registered in the competition database, and the competitor had received a confirmation of successful completion. The best ‘run’ of each competitor was to determine their score and placement in the Regional Championship.The Regional Championship of steelChallenge-17 took place online for 24 hours on 16 November 2022. This year’s steelChallenge attracted 1,298 participants representing more than 70 companies and 80 academic institutions from 27 countries. They used steeluniversity’s steelmaking simulator to produce the best steel at the lowest cost meeting carbon footprint requirements.
