Description

Изобретение относитс  к области цветной металлургии, в частности к способам рафинировани  цветных металлов. Известен способ рафинировани  цветны.ч металлов и их сплавов от железа и других магнитных примесей, включающий наложение магнитного пол . Ио предложенному способу рафинирование ведут при напр женности магнитного пол  более 500 э и при температуре расплава ниже точки Кюри. Это повышает технико-экономические показатели процесса и улучшает качество товарного продукта, например вторичных алюминиевых сплавов. Способ заключаетс  в паложении на рафинируемый расплав магнитного пол  нанр женностью более 500 э при разливке и температуре ниже точки потери магиитных свойс1В железом и другими магнитными примес ми. Пример I. Вторичпый алюминиевы сплав, содержаш,ий 0,062% железа, расплавл ют и при 750°С помешают между пол юса:,; и посто нного магнита иапр женностью 500 э. После застывани  сплав извлекают из тигл  И анализируют. Часть сплава содержит 0,077% железа, количество его составл ет 35% от исходного . Остальной металл содержит 0,048°/о железа. Пример 2. Сплав, содержащий 1,68% железа, подвергают очистке по примеру 1. После очистки получают 70% алюмини , содержащего 0,76% железа, и 30%, содержащего 2,6% железа. Пример 3. Очистка сплава, содержащего 1,94% железа, но примеру 1 позвол ет получить 70% металла, содержащего 1,09% железа , и 30% -- 2,78% железа. Из приведенных примеров видно, что очистка в магнитном поле проходит при различном содержании железа в сплаве, а проведение многостадийноГ очистки позво,1ит практически полностью очистить сплав от железа и других магнитных металлов и их соедипепий. Применение нредлагаемого способа, например, при производстве вторичных алюминиевых сплавов , позвол е1 избежать трудоемкой операции разделки, проводить очистку от железа при разливке в иепрерывном процессе с получепием примерно 70% сплавов с низким содержанием железа и 30% раскислителей дл  черной металлургии. Количество раскислител  может быть умеиьшено при проведении многократной очисткн. Предмет изобретени  Способ рафинированн  цветных металлов и их сплавов от железа и других магиитпых примесей, включаюн;ий наложение магнитного нол  на рафинируемый раснлав, отлича3 ю щ и и с   тем, что, с целью повышени  технико-экопомических показателей процесса и улучшепи  качества товарного продукта, папример вторичных алюминиевых снлавов, ра4 финироваиие ведут при папр женности магнитного пол  более 500 э и при температуре расплава ниже точки Кюри магнитных примесей .This invention relates to the field of non-ferrous metallurgy, in particular, to methods for refining non-ferrous metals. There is a method of refining nonferrous metals and their alloys from iron and other magnetic impurities, including the imposition of a magnetic field. According to the proposed method, the refining is carried out at a magnetic field strength of more than 500 Oe and at a melt temperature below the Curie point. This improves the technical and economic performance of the process and improves the quality of the commercial product, such as secondary aluminum alloys. The method consists in placing a refined magnetic field melt with a density of more than 500 Oe during casting and a temperature below the point of loss of magical properties of iron and other magnetic impurities. Example I. A secondary aluminum alloy, containing 0.062% of iron, is melted and at 750 ° C is interfered between the floor:,; and a permanent magnet with a strength of 500 e. After solidification, the alloy is removed from the crucible and analyzed. Part of the alloy contains 0.077% iron, its amount is 35% of the original. The rest of the metal contains 0.048 ° / o iron. Example 2. An alloy containing 1.68% of iron is subjected to the purification of Example 1. After purification, 70% of aluminum containing 0.76% of iron and 30% of iron containing 2.6% are obtained. Example 3. Purification of an alloy containing 1.94% iron, but example 1 allows 70% of a metal containing 1.09% of iron and 30% - 2.78% of iron to be obtained. From the above examples it can be seen that cleaning in a magnetic field takes place with a different iron content in the alloy, and the multistage cleaning allows us to completely completely clean the alloy from iron and other magnetic metals and their compounds. The application of the proposed method, for example, in the production of secondary aluminum alloys, allowed e1 to avoid the laborious cutting operation, to clean iron from casting in a continuous process with about 70% of alloys with low iron content and 30% deoxidizing agents for ferrous metallurgy. The amount of deoxidizing agent may be decreased by repeated cleaning. The subject of the invention is a method of refining non-ferrous metals and their alloys from iron and other magical impurities, including the imposition of a magnetic zero on a refined rasslav, which is so important that An example of secondary aluminum slavs, the finishing, is carried out with a magnetic field of more than 500 oe and at a melt temperature below the Curie point of magnetic impurities.
