Claims (4)

1. Способ выплавки меди и медных сплавов, включающий расплавление шихты в печи с крышкой, подачу к поверхности постоянно перемешиваемого расплава газообразного окислителя и последующее восстановление расплава, отличающийся тем, что в качестве газообразного окислителя используют водяной пар, подаваемый через фурму со скоростью 1-2 м3/ч, причем расход водяного пара составляет 4-6 м3 на тонну расплава.1. A method for smelting copper and copper alloys, including melting the charge in a furnace with a lid, supplying a gaseous oxidizer to the surface of the continuously stirred melt and subsequent reduction of the melt, characterized in that water vapor is supplied as a gaseous oxidizer through a tuyere at a speed of 1-2 m 3 / h, and the flow rate of water vapor is 4-6 m 3 per ton of melt. 2. Способ по п.1, отличающийся тем, что водяной пар подают через фурму, расположенную на расстоянии не более 30-50 мм от поверхности расплава.2. The method according to claim 1, characterized in that the water vapor is fed through a lance located at a distance of not more than 30-50 mm from the surface of the melt. 3. Способ по п.1 или 2, отличающийся тем, что поверхность крышки печи экранируется со стороны расплава такими материалами как графит, асбест, или угольный порошок.3. The method according to claim 1 or 2, characterized in that the surface of the furnace lid is shielded from the melt side by such materials as graphite, asbestos, or coal powder. 4. Способ по пп.1-3, отличающийся тем, что в шихту после расплавления вводят лигатуру Cu-Р.4. The method according to claims 1 to 3, characterized in that a Cu-P ligature is introduced into the charge after melting.
