The company stated that the new model, based on 40 years of electric arc furnace experience, aims to combine high performance with low capital expenditure.
It was noted that EAF Ultimate Move brings together the strengths of the company’s existing EAF Ultimate and EAF Quantum models, providing maximum flexibility especially for greenfield projects. The new solution is designed to address the capital expenditure-focused needs of investors transitioning to electric steel production.
From a technical perspective, EAF Ultimate Move offers shorter tap-to-tap times and requires a smaller footprint. It also provides advantages such as lower maintenance requirements and reduced overall capital costs.
With this new technology expanding the company’s electric steelmaking portfolio, it was emphasized that different EAF designs continue to address various production needs. The statement highlighted that EAF Ultimate Move stands out as an option for producers seeking maximum flexibility without compromising product quality, while the EAF Ultimate concept—supported by grid-friendly Active Power Feeder and advanced automation—offers a suitable solution for modernizing existing plants. The EAF Quantum model, on the other hand, continues to be preferred by producers focusing on ultra-low consumption values, scrap-based charge mixes, and the preheating of scrap and hot briquetted iron (HBI).
Hans-Joerg Krassnig commented: “For Primetals Technologies, it is natural to combine the most advantageous features and take established EAF technology to the next level. With our latest development, EAF Ultimate Move—which completes our EAF portfolio alongside EAF Quantum and EAF Ultimate—any type of charge material, including hot metal from the blast furnace, can be processed in any combination.”
It was also stated that, thanks to a process inspired by EAF Quantum, the furnace shell can be moved toward the tapping area, enabling a more compact plant design, easier maintenance, and reduced capital requirements for auxiliary equipment such as crane systems and building height. This design is made possible by a movable support frame and an adapted hydraulic tilting system.
EAF Ultimate Move also includes features such as single-bucket operation, single-point roof swing, and the Furnace Advanced Slag-free Tapping (FAST) system. The FAST system allows drilling and plugging while the power is on, significantly reducing the time between two tapping operations.
The company announced that the new electric arc furnace solution was presented to the public at AISTech 2026.
