SUMMARY:New induction heating - a contribution on the way to CO2 neutrality in steel and rolling mills
DESCRIPTION:The steel industry is the second largest industrial emitter of CO2 emissions worldwide. The increasing pressure to reduce these emissions is leading to a move away from fossil fuels in the future. Alternatives are the use of green energy via the generation of DRI/HBI for pig iron production with green hydrogen. In further processing, this opens up new possibilities for alternative applications in the steel making and rolling mill processes, which offer almost CO2-free heating of the material, both in the melting process and in reheating.

One of these alternative processes is induction. The energy input is achieved directly via the electromagnetic field into the material to be heated. The process is dynamic, easily controllable and, if green energy is used, almost CO2-neutral. Both in the melting process and in the area of reheating, the established processes can thus be complemented and thereby reduce the emissions of the overall process. The hybrid addition of induction heating systems not only improves the emission behavior in the overall process at manageable investment costs: Due to lower burning rates of the aggregates and an extremely good stirring effect during the melting process, the process is excellently suited for melting aggregates at the lowest possible energy consumption with good mixing of the target analysis in the melt and with higher yields as conventional processes contribute.

With the dynamic behavior in the heating process due to the direct energy input into the material, the induction heating process is also a good alternative to the existing gas furnace for reheating. The induction furnace can be positioned complementarily upstream or downstream of the gas furnace. Both variants enable a reduction of the total energy consumption as well as the gas consumption and thus a directly measurable CO2 reduction in the reheating process.
