Изобретение относитс  к области .металлургии цветных металов и .касаетс  способа переработки алюминиевых отходов.The invention relates to the field of metallurgy of non-ferrous metals and relates to a method for processing aluminum waste.

Известен способ переработки гор чего съема , образующегос  при плавке лома и отходов алюминиевых сплавав в иидукционной печи с помощью флюса, вводимого в твердо;М состо нии.There is a known method of processing hot metal removal, which is formed during the smelting of scrap and aluminum waste by alloying in an effect furnace with the help of a flux introduced in a solid; M state.

По лредложенному способу гор чий съем обрабатывают жидким флюсом, нагретым до 680-720°С при весовом отнощении его к съему , равном от 0,1 до 0,3. Это уменьщает потери металла при плавке лома и отходов.According to the foregoing method, the hot removal is treated with a liquid flux heated to 680-720 ° C with its weight ratio to the removal equal to from 0.1 to 0.3. This reduces the loss of metal in the smelting of scrap and waste.

Гор чий съем обрабатывают сначала в индукционной печи, а затем вне ее, например в коробе-сите, жидким флюсом, нагретьим до 680-720°С. При этом весовое отношение флюса к .съему составл ет 0,1-0,3. В качестве флюса используют омесь, содержащую 50- 70 вес. % хлористого кали  и 50-30 вес. % хлористого натри .Hot removal is treated first in an induction furnace, and then outside it, for example in a sieve box, with a liquid flux, heated to 680-720 ° C. In this case, the weight ratio of the flux to the removal is 0.1-0.3. As the flux used mixture containing 50- 70 weight. % potassium chloride and 50-30 wt. % sodium chloride.

Способ осуществл ют следующим образом.The method is carried out as follows.

На съем, представл ющий собой щлак с механическими .включени ми частиц алюмини , наход щийс  на зеркале металла в индукционной цечи, заливают жидкий флюс, на,гретый до температуры 680-720°С. При обработке флюса съем поддерживают в гор чем состо нии, не довод  его до жидкого. Йосле перемешивани  съема и флюса смесь выдерживают в течение 1-3 мин. Указанную операцию повтор ют, а затем съем удал ют в короб-сито, который устанавливают возле печи , где съем обрабатывают нагретым до 680- 720°С жидким флюсом. При этом расход флюса не превышает 0,1 вес. ч. к весу съема. Указанные отличи  сиособствуют сли нию частиц металла в крупные корольки и удалению их из шлака в ванну жидкого металла или через отверСти  в коробе-сите в поддон. Способ повышает извлечение металла из отходов алюминиевых сплавов при плавке их в индукционной печи до 96-97 %.For removal, which is a slag with mechanical inclusions of aluminum particles located on the metal mirror in an induction tank, pour liquid flux on it, heated to a temperature of 680-720 ° C. When processing the flux, the removal is maintained in a hot state, not its liquid. After mixing the mixture and flux, the mixture is kept for 1-3 minutes. This operation is repeated, and then the removal is removed in a box-sieve, which is installed near the furnace, where the removal is treated with a liquid flux heated to 680-720 ° C. At the same time, the flux consumption does not exceed 0.1 weight. hours to the weight removal. These differences contribute to the fusion of metal particles into large crowns and their removal from slag into a bath of liquid metal or through holes in a sieve box into a tray. The method improves the extraction of metal from waste aluminum alloys when melting them in an induction furnace to 96-97%.
