grooves on the inner surface of the metal sections, since during heating in the inductor zone there is no direct contact of the ingots with the sections, which

leads to relatively low heat losses and, consequently, to increase the thermal efficiency of the device. During the fusion process, the liquid metal fills the groove in

Q zone of induction and does not go beyond it, which ensures the required quality of welding

The drawing shows an induction melting device, a General view,

5 The induction melting device comprises a cold crucible 1, consisting of longitudinal metal sections 2, an inductor 3 coaxially arranged with t, helmet 1, a movement mechanism 4 of the inductor 3. Ustroevo also contains a sealed chamber 5, a movement mechanism 6 of the metal sections 2, crucible 1, a mechanism download /; and unloading of ingots and the mechanism of 8 rolling 1 of slig during welding Metals 5 ict 1f sections 2 and the parts on the outer surface have recesses 9 in height, with an inductor height of 3, Inward-poiu ° and opera ociM with a glacial tcfii ii 9 throughout illtrine in the induction zone.

The pr-fjoTcieT inertial melting device, which is hermetically sealed in the chamber 5, creates the required working achmoger. Mechanism 7 is implemented

5 ingot loading. The mechanism 6 for the transfer of sections СДШ1ГЯСМ sections crucible, inductor 3 is mixed in the welding zone and is set so that the middle of the inductor 3 is opposite the stick of the ingots Next

Q, voltage is applied to the inductor 3 and heating of the ingots begins. In the process of heating in the ind / ctoZ zone, due to the presence of manhole 10, there is no direct contact on the inner surface of sections 2

5 ingots with sections 2. Contact may be absent during the entire heating process, depending on the depth of the groove, since the diameter of the ingots increases when heated

0 For example, titanium or titanium alloys kmsec significant volume expansion coefficient. When heated to a melting temperature of an ingot with a diameter of 0.67 m, its diameter increases by approximately 9 mm. Outside the inductor zone, due to the low conductivity of the metal, the diameter increases slightly

At the end of the heating process, the power of the inductor 3 increases and a short-time fusion process occurs. Compression mechanism 8

provides at the time of fusion the movement of the ingots towards each other. Next, the power source is turned off, metal crystallizes in the fusion-welding zone. The welded electrode cools down, the inductor 3 moves to its extreme position, where sections 2 of crucible 1 have

recesses on the outside. Sections 2 of crucible 1 are extended, the chamber is depressurized and the electrode is unloaded. The process is considered complete.
