Description
,(54) СПОСОБ ОБРАБОТКИ АЛЮМИНИЕВЫХ СПЛАВОВ, (54) METHOD FOR PROCESSING ALUMINUM ALLOYS
,, : ,1 V ( . .Изобретение относитс к цветной ,,:, 1 V (. The invention relates to color
металлургии, в частности к способам очистки алюминиевы} расплавов .ох растгврренных ,примесей, например водорода. „metallurgy, in particular, to the methods of purification of aluminum melts with dissolved impurities, such as hydrogen. „
: известен способ обработки алюминиевых сплавов, включающий покрытие расплава флюсом,. В качестве флюса используют соли борфтористоводрродной кислоты , например .Фторбораты кали , натри . При этом количее-тво/ флюса, наносйм,ого на поверхн6,сть расплава, берут равнь 1 стехиометрическому количеству, необходимому дл фторировани окиснсэй пленгкй- алюмин,и фтористым бором l. , , , Указанное .количество флюса сравни-тельно велико- и образует на поверхности распла-ва ,.значительный слойу который преп тствует удалению водорода из расплавленного алюминн ., ,. , . . .. ; , Целью Изрбр.ётени вл етс повышение степени очистки сплава от раств,о-- .: There is a known method for treating aluminum alloys that includes melt coating with a flux ,. Salt of hydrofluoric acid is used as a flux, for example. Potassium fluoride, sodium. At the same time, the amount / flux applied on the surface of the melt is equal to 1 stoichiometric amount needed for fluorination with oxide plenky-aluminium and boron fluoride l. The indicated amount of flux is comparatively large and forms on the surface a melt that is significant to the layer that prevents the removal of hydrogen from molten aluminum,,. , . ..; The goal of the Casting is to increase the degree of purification of the alloy from the solution, o--.
ренных газов, например Бодорода. Это Достигаетс тем, что Обработку.сплава : производ т при соотношении флюсрасплав , равном 150-300 г/м поверх-кОсти расплава. ., ,Rena gases, for example, Bodorod. This is achieved by the treatment of the alloy: produced at a ratio of flux-melt equal to 150-300 g / m of the surface of the melt. .,,
. П р и м. е р.. При. осуществлении предлагаемого способа 500 г алюминиевого сплава АМгб обрабатывают тетрафторборатом аммони , который наносит .HS поверхйОсТЬ: расплава из расчета 150-300 г/м поверхности расплава. Температура обработки расплава 700- 72Q С.. For example, at. the implementation of the proposed method, 500 g of aluminum alloy AMgb is treated with ammonium tetrafluoroborate, which causes .HS surface: melt at the rate of 150-300 g / m of the melt surface. The melt processing temperature is 700–72 ° C.
, ,.Срав:нительные результаты по содержанию водорода в сплаве марки ЛМгб приведены в таблице. .,,. Comparative: The significant results on the hydrogen content in LMMB alloy are given in the table. .
Из. данных .таблицы .следует, что описыв .аемый способ обеспечивает- снижевне содержани водорода в расплаве почтиВ два .раза. .Of. The data in the table. It follows that the method described provides for a lower content of hydrogen in the melt almost B two times. .
