Abstract |
Electric steelworks play a fundamental role in the steelmaking transition towards decarbonization. Since scraps are used as their main feedstock, they intrinsically implement the circular economy concept. Nevertheless, further research efforts are being spent to adapt the EAF steelmaking process to the new challenges related to C-lean processes. Potential improvements are related to carbon and energy: fossil carbon has to be replaced by bio-based or alternative carbon materials. The effects of the introduction of these materials in the standard EAF route are not completely known and investigations are needed. Research on these topics is included in some of the activities foreseen in the EU-funded project entitled " Gradual Integration of REnewable carbon and alternative non-carbon Energy sources and modular HEATIing technologies in EAF for progressive CO2 decrease - GreenHeatEAF". It relies on the parallel and complementary application of industrial demonstration and pilot tests, digital simulations, and monitoring and control strategies. One of the tools applied in GreenHeatEAF is a flowsheet model of the EAF steelmaking route. It has been adapted for managing the use and injection of novel carbon sources by exploiting literature and real industrial data. First simulations have been carried out, which are related to sensitivity analyses on the effects of the variation of C and S content in the alternative C-source, and to scenario analyses related to the usage of different alternative C-sources. Key Performance Indicators have been computed for comparing the results from simulations. For the same carbonaceous material, the main process and product parameters seem almost linearly correlated to the variation of C and S content in the carbonaceous material. On the other side, different alternative and non-fossil C-sources gives different behaviours of the EAF route and of product parameters without a clear correlation. Further simulations are ongoing to generalize the preliminary results obtained. |
