The substitution of gas-intensive production processes with electrothermal technologies represents a crucial step toward sustainable manufacturing. Although, this technological transformation still faces challenges and limitations. Next to the carbon footprint, relative price and the available grid infrastructure, electric energy often has to facilitate high-temperature, homogeneous or selective and rapid heating processes in different atmospheres. This paper presents two concepts for direct and indirect electric heating, based on electromagnetic induction, that address these fundamental challenges in industrial manufacturing processes and initiate climate-friendly and sustainable production. It showcases a solution for highly efficient hot gas generation with variable atmospheres that allow homogeneous heating and a solution for selective rapid sheet metal heating.
