(4) Thanks to the prereduction of iron ore, it is possible to reduce the unit consumption of energy in the blast furnace system that uses coalbased energy. It is also possible to reduce the genera tion of carbon dioxide. In addition, since the reduction load is decreased, the blast furnace productivity increases.
