Description

В промышленных услови х вакуумную плавку металлов и сплавов ведут в тигельных индукщио.нных и дуговых печах с расходуемым электродом.Under industrial conditions, vacuum smelting of metals and alloys is carried out in crucible induction furnaces and arc furnaces with a consumable electrode.

Известные плавильные агрегаты имеют р д недостатков. Так, в (вакуумных тигельных печах огнеупорна  керамика тиглей и форм загр зн ет сплав. Дуговые вакуумные печи с расходуемым электродом в зоне горени  дуги перегревают металл: высока  температурка дуги образует пары металла, которые уменьшают разрежение в зоне плавлени  и эти.м ухудшают дегазацию металла. Известные агрегаты трудно использовать дл  получени  фасонного лить .Known melting units have a number of disadvantages. Thus, in (vacuum crucible furnaces, refractory ceramics of crucibles and molds pollute the alloy. Arc vacuum furnaces with a consumable electrode in the arc burning zone overheat the metal: a high arc temperature forms metal vapors that reduce the vacuum in the melting zone and these m impair the degassing of the metal Known aggregates are difficult to use for shaped casting.

Предлагаемое бестигельное вакуумное индукционное устройство полунепрерывного действи  с приспособлением дл  индукционного перемешивани  расплава и измельчени  зерна устран ет указанные недостатки .The proposed crucible vacuum induction device of semi-continuous action with a device for induction mixing of the melt and grinding of grain eliminates these drawbacks.

Совмещение бестигельной индукционной плавки с разливкой в вакууме и индукционным перемешиванием расплава непосредственно в форме в одном агрегате позвол ет получать довольно чистые сплавы и стали с однородной и мелкозернистой структурой. В результате переплавки сплавов и сталей в предлагаемом устройстве заметно повышаетс  их пластичность, резко уменьшаетс  содержание газов и неметаллических включений.The combination of the crucibleless induction melting with vacuum casting and inductional stirring of the melt directly in the form in one unit makes it possible to obtain fairly pure alloys and steels with a uniform and fine-grained structure. As a result of the remelting of alloys and steels in the proposed device, their plasticity increases markedly, the content of gases and non-metallic inclusions sharply decreases.

На чертеже изображено предлагаемое устройство.The drawing shows the proposed device.

Устройство состоит из вакуумной плавильной печи 1 со съемной крышкой 2, на которой смонтирован механизм 3 подачи электрода с приводом. Внутри печи / размещены плавильный «ндуктор 4 и индуктор 5 дл  перемешивани  расплава и измельчени  зерна при затвердевании отливки.The device consists of a vacuum melting furnace 1 with a removable lid 2, on which is mounted the mechanism 3 for supplying the electrode with a drive. A melter inductor 4 and an inductor 5 are placed inside the furnace / for stirring the melt and grinding the grain during solidification of the casting.

Плавильный индуктор 4 питаетс  током повышенной частоты, а индуктор 5 - током промышленной частоты. Вакуум плавильной камеры создаетс  бустёрными 6 и механическими 7 насосами.The melting inductor 4 is powered by a current of increased frequency, and the inductor 5 is powered by a current of industrial frequency. The vacuum of the smelting chamber is created by a booster 6 and a mechanical 7 pump.
