摘要： A charge of scrap is melted in a furnace (1) with post-combustion of the fumes by injection of an oxygenated gas into the space in the furnace above the charge. During periods of post-combustion, the oxygenated gas is injected in the form of several jets each having a flow rate comprised between about 400 and 1200 Nm.sup.3 /h and an injector (11, 12) outlet speed comprised between about 50 and 150 m/s, preferably between about 500 and 900 Nm.sup.3 /h and between about 70 and 125 m/s. Several groups of injectors (11, 12) are used, having an outlet tangential component relative to the vertical axis (X--X) of the furnace (1), successive groups of injectors being disposed at different levels (N.sub.1, N.sub.2) and oriented in alternate circumferential directions. A portion of these injectors have a circumferential component in a first direction and a downward component at a first angle relative to the horizontal, and the other injectors have a circumferential component in an opposite direction and a downward component at a second angle different from the first angle. The oxygenated gas is oxygen having a purity of at least 90%.

摘要： Provided is a process for melting a charge in a furnace. Energy of fusion is supplied to the charge, and gases including at least one combustible gas are generated during the the melting. A post-combustion of the combustible gas is performed by injecting an oxidant gas containing more than 25% by volume of oxygen during at least some periods of the process. The oxidant gas is injected above the charge, in the form of at least one oxidant gas jet. Each jet has a flow rate of between approximately 50 and 1200 Sm.sup.3 /h and a speed of injection into the furnace of between approximately 5 m/s and 150 m/s. The process has particular applicability to an electrical furnace for melting scrap for the production of steel.

摘要： A furnace comprises a space overlying a charge into which space opens at least one oxygenated gas injector passing through the periphery of the furnace to deliver within this space a jet of gas that is nonradial relative to a vertical axis of the space. Each injector comprises a) a head (14) disposed within the thickness of the wall (1) of the furnace and having a gas passage having an axis (11) inclined at a predetermined angle (.alpha.) to an axis (15) that is substantially radial relative to the vertical axis of the space overlying the charge and b) a substantially cylindrical body (16) prolonging the head and the gas passage within the furnace along this substantially radial axis (15), itself substantially perpendicular to the wall (1) through which it passes. The injector is useful in an electric furnace for melting scrap for the production of steel.
