An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc, combined with the action of chemical power provided by the use of oxygen and fuel. In electric arc furnaces, the charged material is directly exposed to an electric arc, and current from the furnace electrodes passes through the charged material.
The project will fundamentally change the way steel is made at ArcelorMittal Dofasco, transitioning the site to direct reduced iron-electric arc furnace ('DRI-EAF') steelmaking, which carries a considerably lower carbon footprint and removes coal from the ironmaking process.
