Groundbreaking energy-saving blast-furnace technologies are needed to reduce the energy costs in the production of hot metal and converter steel. The reduction in coke consumption and increase in productivity when hot reducing gases are injected into the blast furnace are assessed on the basis of calculations and industrial trials. The composition of the reducing gases is described before and after compression of the blast-furnace gases. Systems for recycling the blast-furnace gas and removing the CO are considered. The economic and energy benefits obtained by the injection of hot reducing gases are appraised. The energy efficiency of hot-metal production is increased by 40%. [ABSTRACT FROM AUTHOR] |
