Abstract
Overheated reducing gases are injected into the blast-furnace, at the main blast-pipes, at a temperature ranging from 1500 to 2800'C, produced from solid fuel, said gases containing essentially CO, H<u2>u, N<u2>u, CO<u2>u and H<u2>uO. These reducing gases are obtained from a solid fuel, preferably dried and finely ground, injected in adequate proportions (O/carbon ratio) in a reactor where it is gasified by contact with an oxidizing agent such as air, over oxygenated wind or recycled top gases having a sufficient CO<u2>u content. These reducing gases are preferably overheated by electric process, particularly in a plasma torch.
