Изобретение относитс  к оборудованию, примен емому при производстве металлов и сплавов .The invention relates to equipment used in the production of metals and alloys.

Известно устройство дл  рафинировани  жидких металлов и сплавов, включающее -корпус , выполненный в виде перфорированного закрытого с одного торца цилиндра, жестко закреплеиного на валу, и привода.A device for refining liquid metals and alloys is known, including a housing, made in the form of a perforated cylinder closed at one end, rigidly fixed to the shaft, and a drive.

Предложенное устройство отличаетс  тем, что цилиндр закрытым перфорированным торцом закреплен па валу, а внутри цилиндра укреплена крыльчатка, лопасти которой расположены под УГЛОМ 20-30° к оси вращени .The proposed device is characterized in that a cylinder with a closed perforated end is fixed on the shaft, and an impeller is fixed inside the cylinder, the blades of which are located under the ANGLE 20-30 ° to the axis of rotation.

Это позвол ет упростить ко 1струкцию устройства и повысить эффективность расплава.This simplifies the design of the device and increases the melt efficiency.

На фиг. 1 изображено описываемое устройство , общий вид; на фиг. 2 - то же, разрез по Л-А.FIG. 1 shows the described device, a general view; in fig. 2 - the same, section on LA.

Устройство содержит вал 1 с приводом н стакан 2, изготовленный из материала, не реагирующего с рафинируемым расплавом. Бокова  новер.хность стакана 2 перфорирована отверсти ми а диаметром 0,4-2,0 мм, а торцова  поверхность - отверсти ми б диаметром 8-10 мм. К валу 1 приварен стакан 2 н крыльчатка 3, котора  вставлена внутрь стакана . Крыльчатка имеет две лопасти 4 с наклоном в 20-30° к оси вращени .The device comprises a shaft 1 with a drive n glass 2, made of a material that does not react with the refined melt. The lateral recess of the cup 2 is perforated with holes a with a diameter of 0.4-2.0 mm, and the front surface with holes with a diameter of 8-10 mm. A 2 n impeller 3 welded to the shaft 1, which is inserted into the inside of the glass. The impeller has two blades 4 with a slope of 20-30 ° to the axis of rotation.

Устройство погружают в рафинируемый расплав, включают привод и дают 100- 300 об/мин. Расплав под действием гидростатического давлени  и вращающихс  наклон5 иых лопастей 4 крыльчатки заполн ет стакан и вращаетс  с той же скоростью, что и устройство , так как лопасти не допускают проскальзывани  расплава. Под действием центробежных СИЛ жидка  фаза фильтруетс  через боковые отверсти  а стакана, а тверда  фаза остаетс  на его внутренней поверхности, как на фильтре. Часть расплава проходит через отверсти  б в торце стакана не фильтру сь, благодар  чему создаетс  необходима  цнр5 кул ци  раснлава, котора  обеспечивает многократное нрохождение его через устройство. В результате того, что забор расплава в устройство осуществл етс  через открытый нижний торец стакана, можно отфильтровать ин0 терметаллические соеднненн , выпавщие из расплава и лежащие на дне сосуда. Так как вес погружаемой части устройства ничтожен по сравнению с весом рафиннруемого расплава , оно не вносит тепловых возмущений в температурном поле расплава, что дает возможность рафинировать его при температуре на 5-10°С выше солидуса, что позвол ет улучщить степень очистки.The device is immersed in the refined melt, turn on the drive and give 100-300 rpm. The melt under the action of hydrostatic pressure and rotating tilting blades 4 of the impeller fills the cup and rotates at the same speed as the device, since the blades prevent the melt from slipping. Under the action of centrifugal SIL, the liquid phase is filtered through the side openings of the glass, and the solid phase remains on its inner surface, as on a filter. A part of the melt passes through the holes b in the butt end of the glass and does not filter, due to which it creates the necessary core for rasklava, which ensures its repeated passage through the device. Due to the fact that the melt is taken into the device through the open lower end of the glass, it is possible to filter intermetallic compounds falling out of the melt and lying at the bottom of the vessel. Since the weight of the submerged part of the device is negligible compared to the weight of the refinable melt, it does not introduce thermal perturbations in the temperature field of the melt, which makes it possible to refine it at a temperature of 5-10 ° C above the solidus, which allows for improved purification.

По окончании процесса центрифугировани  вращающеес  устройство извлекают из расплава и над его поверхностью увеличивают число оборотов до 3000-4000 в 1 мин. В результате происходит почти полное отделение жидкой фазы от твердой (за счет центробежных сил), благодар  чему получают «сухие дроссы. Они легко удал ютс  через нижний открытый торец стакана при постукивании устройства. Простота конструкции и малые размеры дают возможность примен ть устройство непосредственно в печах, миксерах и разливочных ковщах.At the end of the centrifugation process, the rotating device is removed from the melt and the number of revolutions is increased to 3000-4000 in 1 minute above its surface. As a result, there is an almost complete separation of the liquid phase from the solid phase (due to centrifugal forces), due to which “dry dross are obtained. They are easily removed through the lower open end of the glass when the device is tapped. The simplicity of construction and small dimensions make it possible to apply the device directly in furnaces, mixers and casting dugs.
