Abstract
A method of manufacturing molten pig iron into an electrical smelting unit. The method includes the following successive steps: providing a directly reduced iron product, feeding the DRI product into the smelting unit, feeding together with the DRI product at least one steel or ironmaking by-product-based material including at least 10% in weight of slag forming agents, and melting the DRI product and the at least one steel or ironmaking by-product-based material to produce molten pig iron. A steel manufacturing method using the pig iron is also provided.
