The 80 t converter using iron ore partly instead of scrap as cold material in the steelmaking plant of Xiangtan Iron and Steel Group Corporation was introduced. By adjusting material ratio in the converter and optimizing the operation, the cost of steelmaking was reduced. It proved that with iron ore alternative to scrap, the iron ore consumption was increased and the scrape consumption was decreased, and the costs of oxygen, steel material and flux, etc. were dropped.
