Description
Technical field
The present invention relates to melting art field, especially a kind of feed system based on electron-beam cold bed furnace.
Background technology
Electron-beam cold bed furnace is a kind of smelting furnace, is grown up the sixties in 20 worlds, by the development of decades, excellent
Considerable status has been occupied in the production of matter titanium or titanium alloy ingot blank, compared with traditional vacuum consumable arc-melting stove, electricity
The melting of beamlet cold hearth have can remove high and low density inclusions.It can be with melting original charging and 100% titanium defective material and low product
Matter Hami is safe and sound, many advantages, such as directly producing variously-shaped ingot casting and slab, and it is history of metallurgy the next item up to be identified as
Important achievement.
Electron beam cold hearth melting makees heat source with electron beam, and water jacketed copper crucible is cold bed, is converted using the kinetic energy of high-velocity electrons
Make metal molten, refining, casting ingot into thermal energy.Its operation principle is at high vacuum (vacuum degree is generally in 10-1 to 10-3Pa)
In environment, cathode (tantalum or tungsten filament) is heated, cathode will launch a large amount of thermoelectrons, if keeping big between cathode and anode at this time
Potential difference, then electronics accelerate under electric field action, electric energy is converted into the kinetic energy of electronics, assembles electron beam with electric field and magnetic field,
Its bombardment is made to want molten metal, electronics loses kinetic energy in same metal bump, is transformed into the heat mainly as melting batch
Amount, makes metal molten, it can be effectively prevented from molten metal and be polluted by refractory material.Accordingly, it can be said that electron-beam cold bed furnace
Melting is some metal materials, particularly refractory metal provides a kind of indispensable refining means.
But in the actual production of electron-beam cold bed furnace melting technique, due to charging rate, control fusing speed and
The mismatch of ingot speed degree is drawn to be easy to cause titanium ingot cold shut, fold occur, be mingled with, the casting flaws such as grain growth is irregular, rear
Continuous titanium products production must increase the cumbersome process such as cutting, classification, consolidation, substantially reduce production efficiency, and then increase production
Cost.Feed system is the indispensable important component of electron beam furnace, it is communicated with furnace body, and a set of vacuum is shared with furnace body
System, effect are the positions that transferring raw material stick can accurately be bombarded to electron beam, so that fuel rod fusing instills crucible
It is interior.When blank diameter is more than crucible diameter or larger blank bending change, part blank is just had beyond crucible diameter.Electronics
When beam melts blank, the blank beyond crucible diameter cannot melt, when other parts blank melts, beyond crucible diameter part
Blank will fall on outside crucible, prevent electron beam furnace from normally producing.

Angle of inclination control 2/3rds of maximal angle value, and pass through angle detector and confirm that its angle value feeds back to control
Device；By the horizontal displacement of crumble hopper after a quarter of opposite direction movement total displacement in electron-beam cold bed furnace stove, carry out
Crumble charging acts, and completes the melt of crumble；
When considering material granularity to be worth doing more than 60mm, using above-mentioned rate-determining steps, telescoping mechanism is shunk into certain distance, by crumble hopper
Angle of inclination is controlled 1/3rd of maximal angle value, and is passed through angle detector and confirmed that its angle value feeds back to controller；
By the horizontal displacement of crumble hopper after 1/3rd of opposite direction movement total displacement in electron-beam cold bed furnace stove, crumble is carried out
Charging acts, and completes the melt of crumble；
The control process of material all in one piece feed system：After material all in one piece charging enters feed barrel, controller controls conveying device according to setting
Speed conveys material all in one piece, velometer Real-time Feedback speed to controller；When pyroscan detects that material all in one piece has non-melting part
When outside the scope of beam bombardment, after controller receives pyroscan feedack, position sensor is monitored
Detent mechanism location information, control detent mechanism cooperation rotating device complete rotation material all in one piece action, material all in one piece is made to be moved to electricity
In the range of beamlet bombardment, until completing the melting of material all in one piece.
