The first step in making SSAB Zero is to feed the electric arc furnace (EAF) with scrap. Heat is generated from an electric arc between electrodes. Oxygen is blown into the furnace, and lime and slag foamers are added to combine with the impurities and form slag. Molten iron is extracted and poured out via a tapping spout. Across the entire process, only fossil-free electricity and fuels will be used – resulting in SSAB Zero steel as the end-product.
