Claims (5)

1. Способ обработки ванадиевого шлака, включающий восстановительное обогащение шлака углеродом, металлотермическое восстановление обогащенного шлака, отделение восстановленного металла от шлака, отличающийся тем, что восстановительное обогащение шлака производят углеродом при выпуске жидкого шлака из сталеплавильного агрегата, а металлотермическое восстановление производят элементами с большим, чем у углерода, сродством к кислороду при температурах жидкого шлака, которые подают ниже поверхности и/или под струю расплава.1. The method of processing vanadium slag, including reductive enrichment of slag with carbon, metallothermal recovery of enriched slag, separation of the reduced metal from slag, characterized in that reductive enrichment of the slag is produced by carbon upon the release of liquid slag from the steelmaking unit, and metallothermic reduction is carried out by elements with greater than in carbon, an affinity for oxygen at liquid slag temperatures that are fed below the surface and / or under the melt stream. 2. Способ по п. 1, отличающийся тем, что восстановительное обогащение шлака производят углеродом кокса, каменных углей, боя угольных футеровок и электродов. 2. The method according to p. 1, characterized in that the re-enrichment of slag is carried out with carbon of coke, coal, battle of coal lining and electrodes. 3. Способ по п. 1, отличающийся тем, что металлотермическое восстановление обогащенного шлака производят сплавами и лигатурами, содержащими алюминий, кремний, кальций, магний, титан. 3. The method according to p. 1, characterized in that the metallothermic reduction of the enriched slag is performed by alloys and alloys containing aluminum, silicon, calcium, magnesium, titanium. 4. Способ по п. 1, отличающийся тем, что обработку ванадиевого конвертерного шлака производят в сталеплавильном агрегате и/или в ковше, футерованном огнеупорами, обладающими более высокими, чем у шамота, огнеупорными свойствами. 4. The method according to p. 1, characterized in that the processing of vanadium converter slag is carried out in a steelmaking unit and / or in a ladle lined with refractories having higher refractory properties than chamotte. 5. Способ по п. 1, отличающийся тем, что углерод и элементы для металлотермического восстановления подают в струе газа-носителя ниже поверхности расплава. 5. The method according to p. 1, characterized in that carbon and elements for metallothermal reduction are fed in a stream of carrier gas below the surface of the melt.
