pEAF

pEAF is an acronym commonly used in the steelmaking industry to describe a partially electric arc furnace technology, a variant of the electric arc furnace (EAF) process. The term is not standardized, and different manufacturers may use pEAF to denote configurations that blend electric melting with additional heat sources or advanced process controls. The core idea is to enhance energy efficiency, flexibility, and control over the melting and refining stages while leveraging the existing electric arc technology.

In typical pEAF configurations, the furnace melts a feedstock primarily from steel scrap, with supplementary heat or energy management provided by additional burners, post-combustion of off-gases, or other energy sources. This approach aims to improve energy use, allow higher scrap-to-DRI ratios, and enable tighter control of temperature and slag chemistry. Operators emphasize the ability to adjust energy input dynamically, potentially reducing fuel use and processing times compared to conventional EAFs.

Industry use and considerations: pEAF technologies are pursued as part of decarbonization and efficiency goals within modern steelmaking. Benefits cited include greater feedstock flexibility, potential reductions in energy intensity, and improved process stability. Challenges include higher capital costs, more complex control systems, and the need for consistent feedstock quality to maximize benefits. The term’s meaning can vary by vendor, so projects should verify the exact configuration and performance claims from the equipment supplier.
