摘要： Melting plant (10) and relative method for the production of steel, comprising a melting furnace (11) fed laterally with a metal charge conveyed towards the melting furnace (11) by means of a conveyor (12) disposed at least partly inside a tunnel (13) in which the fumes exiting from the melting furnace (11) are made to transit in counter-flow with respect to the metal charge in order to heat it, and discharge members ( 15 ) which discharge the fumes from the tunnel (13) towards the outside environment, possibly after having been treated. The melting plant (10) also comprises diversion means (16), located between the melting furnace (11) and the discharge members (15), able to be selectively activated to convey the fumes directly into the discharge members (15), bypassing the tunnel (13).

摘要： A process and an apparatus for producing metals from a metalliferous feed material are disclosed. The process includes the steps of partially reducing and at least partially melting a metalliferous feed material in a pre-reduction/melting means and completely reducing the partially reduced feed material in a reduction means. The pre-reduction/melting means is positioned directly above the reduction means and communicates with the reduction means so that at least partially molten, partially reduced feed material flows downwardly into a central region of the reduction means. The reduction means includes a vessel that contains a molten bath having a metal layer and a slag layer on the metal layer. The process includes injecting oxygen-containing gas into the reduction means and post-combusting reaction gas generated in the molten bath and injecting oxygen-containing gas into the pre-reduction/melting means and post-combusting reaction gas discharged from the reduction means. The process further includes injecting solid carbonaceous material and a carrier gas into a metal rich region of the molten bath and causing upward movement of splashes, droplets and streams of molten material which forms a transition zone.

摘要： A metal scrap melting submergence device for a chargewell of a melting furnace comprises an open top chamber (116) including walls of a heat resistant material, an inlet (126) positioned in a side wall of the chamber, an outlet (124) positioned in the base of said chamber, and a sloped ramp (121) adjacent said side wall of the chamber. The ramp rises from a base (120) spirally along the chamber circumference and includes an inner wall (122) from an inner edge of the ramp. The top edge of said inner wall will be at approximately the same height as the terminal edge of the ramp.
