Webb17 mars 2024 · Overview of the steel production process. Steel is principally made via two routes, the last Furnace-Basic Oxygen Furnace (BF-BOF) route and the Electric Arc Furnace route (EAF) - often referred to as the 'primary' and 'secondary' paths. The former is used to create new or 'virgin' steel, the latter is often used to recycle steel scrap.
