New Technologies of Energy Saving and Low CO₂ Emission for Iron Making

Abstract:

Energy saving has drawn more and more attention of the world due to the pressure of the environment and society. Metallurgy is one of the biggest energy consumption industries, accounting for about 16% of the total industry, basically the same ratio as the emission of CO₂ and other pollutants. About 70% of total energy for steel production is consumed in iron-making process with the same ratio of CO₂ discharged, so it has a great significance to achieve energy saving and low CO₂ emission in iron-making process. The new iron-making technologies with energy saving and low CO₂ emission such as oxygen blast furnace, ITmk3, application of waste plastics and biomass in iron-making, were introduced in the present work. Particularly, the latest research progress, merit and demerit were compared, and the contribution of the different technologies to low CO2 emission and the energy saving were analyzed.
