Abstract: The electric arc control device may be applied to an arc furnace comprising at least one reaction chamber wherein at least two electrodes are arranged, a fuel injection device, optionally an other device for introducing a combustive material and optionally means for creating one or a plurality of magnetic fields in the above mentioned reaction chamber. It further comprises means for displacing the electric arc, consisting essentially in aerodynamic field generators, these fields being themselves susceptible of being speed- and/or direction-modulated.

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 u, N u, CO u and H 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 u content. These reducing gases are preferably overheated by electric process, particularly in a plasma torch.
