Изобретение относитс к области металлургии, в частности к получению и рафинированию металловThis invention relates to the field of metallurgy, in particular to the production and refining of metals.
Известно ycTpolicTBO дл ультразвуковой дегазации расплавов металлов, например, алюмини и сплавов на его основе, включающее литейный желоб с излучател ми ультразвука и кристаллизатор.YcTpolicTBO is known for the ultrasonic degassing of metal melts, for example, aluminum and alloys based on it, including a casting trough with ultrasound emitters and a crystallizer.
Это устройство не обеспечивает высокой степени дегазации расплава в св зи с нарушением сплошности поверхностной окисной пленки и отсутствием условий дл формировани развитой области кавитации.This device does not provide a high degree of melt degassing due to the discontinuity of the surface oxide film and the absence of conditions for the formation of a developed cavitation region.
Целью изобретени вл етс повышение эффективности дегазации расплавов металлов.The aim of the invention is to increase the efficiency of degassing molten metals.
Предлагаемое устройство отличаетс от известного тем, что его излучатели ультразвука акустически независимо установлены в дне желоба , высота которого ступенчато увеличиваетс на 1/4 длины волны звука в материале-расплава по мере рриближени к кристаллизатору, аThe proposed device differs from the known one in that its ultrasound emitters are acoustically independently mounted in the bottom of the chute, the height of which increases in steps by длины of the sound wavelength in the melt material as it approaches the mold and
площадь поверхности излучателей ультразвука составл ет 10-40 площади дна желоба.The surface area of the ultrasound emitters is 10-40 of the bottom of the gutter.
На чертеже схематически изображено предлагаеюе устройство, состо щее из миксера I, излучателей ультразвутса 2, литейного желоба 3,. кристаллизатора 4 и уплотнений 5.The drawing shows schematically a proposed device consisting of a mixer I, ultrasound emitters 2, a casting trough 3 ,. mold 4 and seals 5.
10 Стру расплавленного металла из миксера 1 поступает в литейный желоб 3 с встроенным в дно посредством уплотнений 5 излучател ми ультразвука 2, После ультразвуковой J5 обработки в желобе расплав направл етс в кристаллизатор 4.10 A stream of molten metal from mixer 1 enters the casting chute 3 with ultrasound emitters 2 embedded in the bottom by means of seals. After an ultrasonic J5 treatment in the chute, the melt is directed to the crystallizer 4.
Предлагаемое устройство позвол ет снизить содержание водорода в расплавах алюмини и его сплавов на 50 и более.The proposed device allows reducing the hydrogen content in molten aluminum and its alloys by 50 or more.
