The metal that melting is wanted with bombardment after scanning, melts refractory metal.Electron beam is narrow with melting zone, energy density is high and melting zone
The advantages that interior average temperature gradient is big, has been successfully used to the refractory metals such as W, Mo, Ta, Nb, Zr, Hf, refractory metal chemical combination
Object, the purification of active metal and its alloy and the purification of silicon material.
Electron beam furnace includes: furnace body and one group of high-power electron gun of arranging, ingot casting crucible, drag ingot at feed system
System, vacuum pump set, hydrologic cycle cooling system and electric-control system.It is in underground, wherein dragging ingot system bearing that this, which drags ingot system,
Ingot casting and the effect for controlling its lifting discharging.Structure is complicated for traditional support ingot device, specifically includes that discharge barrel, draws spindle blade, draws ingot
Bar rotating electric machine, ball screw assembly, ball screw assembly, rotating electric machine, slide rail, hoist engine, travelling bogie etc..Spindle blade is drawn to connect
Dummy bar head is connect, is extended to ingot casting crucible, the mobilizable interior bottom of ingot casting crucible is formed, forms molten bath in crucible.Carry out melting
When operation, metallic solution solidification is coagulated together with dummy bar head, spindle blade is drawn both to be able to maintain lifting, is also able to maintain itself rotation,
Spindle is continuously pulled out from crucible, and then the more experienced ingot casting the longer in crucible.When melting terminates to prepare ingot out, can make to draw spindle blade drop
To lowest order, steel wire rope of windlass decentralization moves down discharge barrel integrally along sliding rail, and guarantee reaches discharge height.Later
Ingot device will be dragged to remove together together with spindle by travelling bogie.
Traditional function of dragging ingot device that can effectively realize ingot casting and feeding, but there are also the spaces of optimization for structure and efficiency:
1. travelling bogie is walked in underground, occupied space is larger；Need to dig two layers of ditch, the wheel of travelling bogie is
It walks on track in one trench, for driving the motor for drawing spindle blade to move up and down and lead screw to be placed in second layer ditch.Due to
Wheel is placed in travelling bogie middle and lower part, will lead to gravity center instability in travelling bogie traveling, and vehicle body in traveling is caused to rock, make to discharge
Cylinder is not easy centering, can only use and slow down travel speed, repeatedly slows down influence to medium mode；
2. hoist engine occupied space is larger and structure is complicated, the danger of disconnection is likely to occur using wirerope for a long time；
3. spindle motor is dragging ingot device bottommost, the entire length for dragging ingot device is increased, keeps ground deeper, and not
Facilitate maintenance；
4. discharge tank opens up 2 clean-up ports, when clearing up discharge barrel, go to clear up without discharge barrel of dismantling, blind hole flange
Opening can be cleared up directly, easy to operate simple；
5. travelling bogie positioning device only configures a travel switch, brake not sensitive enough；
6. travelling bogie brake gear is completed by hydraulic cylinder control banking pin, there is time delay, braking effect is bad, greatly
The precision of discharge barrel and furnace body flange centering is influenced, can only also be used and be slowed down travel speed, shadow is slowed down to medium mode to this
It rings.The operation difficulty of field personnel is increased significantly.

Side wall is connected by pin shaft, and the cylinder bottom of the cylinder is fixed in the support plate of the bracket.
The clean-up port is 2.
Beneficial effects of the present invention: 1. remove travelling bogie, and are used for mobile wheel for four and are placed in whole device
Top, the wheel of wheel carrier have been moved on on ground and have been walked, and track is arranged on the ground, are not easy to topple over, and center of gravity is more steady, are reduced
The difficulty of discharge barrel centering, simplifies overall structure, one layer of ditch also need to be only dug when reducing occupied area, and building ground；
2. removing hoist engine, the lifting of control discharge barrel is substituted by cylinder.Structure is simplified, occupied area, work are reduced
Make more reliable and easy to installation and maintenance, and eliminates the security risk that steel wire rope of windlass may disconnect；
3. spindle motor position moves on to top by bottom, reduces the entire length for dragging ingot device, alleviates construction intensity,
And it is easy to installation and maintenance；
4. discharge barrel opens up 2 cleaning eyes, easy cleaning；
5. it is 2 that the positioning device of wheel carrier, which increases travel switch quantity, when touching retarding travel switchs, wheel is controlled
Decelerating through motor, touching braking distance switch when, open brake gear.Solve traditional structure causes to stop since acceleration is excessive
Incessantly the problem of vehicle, make discharge barrel and furnace body flange exactitude position；
6. brake gear is changed to the brake at motor control wheel end by the brake of Hydraulic Cylinder pin to brake, tie
Structure is simpler, brakes sensitiveer.
