Overview

This research contributes to green steelmaking by investigating the effect of tramp elements on the surface quality of steels after reheating.

Steel production is estimated to account for approximately 7% of global CO₂ emissions. Achieving sustainable steel production requires a combination of green hydrogen usage, full recycling of scrap steel, and the electrification of processes. The adoption of new sustainable process technologies will necessitate changes in heat treatment methods, particularly in heating systems. These changes will primarily affect furnace atmospheres, which in turn influence surface reactions during steel processing.

Additionally, the increased use of recycled steel introduces trace elements—known as tramp elements— that alter steel composition. This has important implications for surface quality, surface-dependent mechanical properties, and product manufacturability.

This project aims at understanding the oxidation processes occurring in reheating furnaces, where the as-cast steel is heat-treated to optimise its mechanical properties for entering the rolling mills.

The transition from fossil-based to green furnace atmospheres will lead to an increase in water and CO2 content in the furnace, thereby affecting the kinetics of growth and morphology of the oxide layer. In green steelmaking it is also aimed at reusing steel from scrap. The introduced tramp elements are expected to influence growth kinetics, type and morphology of the formed oxides. Important features of the oxide layer for further steps in steelmaking are the porosity, the layer thickness (loss of iron) and the adhesion of the oxide to the substrate, a key factor for descalability.

Oxidation also causes steel surfaces to change from reflective metals to absorbing dielectrics. The thickness and morphology of the oxide determine the emissivity, which affects both the heat transfer and the temperature profile during processing.

The research project considers first the analysis of the possible oxide phases formed and the characterisation of the external oxidation layer. The analysis includes the morphology and the specific features of oxide layers grown in wet oxidation conditions for a group of steel of interest to all partners. Next the insights gained on surface evolution due to oxidation will be incorporated into predictive emissivity models to enable precise temperature control during reheating.

And finally, the effect of tramp elements on the oxidation behaviour will be tackled. Ultimately, the project aims to develop a predictive model for oxide growth and emissivity under sustainable reheating conditions.
