Description
Technical field
The present invention relates to a kind of titanium process technology, a kind of recovery method of TC4 titanium alloys defective material is particularly related to.
Background technology
Ti-6Al-4V (TC4) titanium alloy intensity is high, excellent combination property, good processability, is widely used in aviation, warship
The fields such as ship, weapons, physical culture, its output accounts for titanium alloy total output more than 50%, but because production cost is high, limits it
Further genralrlization application, therefore the technique and method of reduces cost are all being explored in countries in the world.In the titanium sponge cost of raw material not
Under the present situation that can be further remarkably decreased, titanium alloy scraps recycle is one of maximally efficient method of reduces cost.Prior art master
To be reclaimed using vacuum arc furnace ignition (VAR) melting, process route for " titanium defective material scale → surface treatment → binding group welding electrode →
VAR melting → secondary VAR meltings → machining ", can obtain the melting of TC4 titanium defective materials and reclaim circular titanium ingot, but be needed bundle
The limitation of group welding electrode is tied up, is only capable of reclaiming dimensions larger tabular, bar-shaped or base head class defective material, it is impossible to less to size
Granular scraps recycle, therefore titanium defective material shape is poor for applicability.Because the VAR melting degrees of superheat are low, high and low density inclusions are difficult
Remove, while 2 times and above number of times melting also result in the increase of O, N objectionable impurities elements, it is not ideal enough that quality is reclaimed in melting.This
Outward, above-mentioned process is only capable of obtaining circular titanium ingot, when plate purposes is rolled, also needs through excessive fire time heating, forging, reconditioning
Stripping off the skin and machine the operations such as square billet needed for acquisition rolling-cogging, reconditioning strips off the skin, crop end can be greatly reduced lumber recovery, production stream
Journey is long, high cost.Therefore, in the defective material melting recovery of TC4 titanium alloys and application aspect there is titanium defective material shape and be applicable in prior art
Property poor, production procedure is long, high cost, objectionable impurities elements increment are big, high/low density field trash is difficult the shortcoming of removal, in economy
Property and quality aspect effect it is not ideal enough, it is necessary to explore new melting recovery method.
The content of the invention
The present invention is in order to solve the above-mentioned technical problem, there is provided a kind of recovery method of TC4 titanium alloys defective material, its effective solution
Traditional titanium defective material shape is poor for applicability, production procedure is long, high cost, objectionable impurities elements increment big, high/low density field trash
The problems such as being difficult removal.
The technical solution adopted in the present invention is：A kind of recovery method of TC4 titanium alloys defective material, comprises the following steps：
Step one, choose pending TC4 titanium alloys defective material and remove the impurity on its surface, clean surface, dry is obtained after drying

Than Al element evaporations scaling loss percentage y%, melting recovery Pd ingot Al element mass percent desired value z% in x%, fusion process, really
The weight m of fine aluminium is added needed for fixed each hopper, wherein, dispensing formula is：[(M*x%+m) * (1-y%)]/[M+m-(M*x%+
m) *y%)]=z%；
Step 5, the quality of calculating in step 4, weigh the aluminium in TC4 titanium alloys defective material and the step 3 in step one
Thin plate, and the method that the TC4 titanium alloys defective material chosen according to aluminium sheet and by step one is alternately laid from the bottom to top carries out cloth,
It is standby after the completion of cloth and the charging box the superiors are TC4 titanium alloy defective materials；
Step 6, EB cold hearth feed systems will be put into through the good charging box of step 5 cloth, and feed space, working chamber are carried out
When being evacuated to feed space vacuum≤0.6Pa, working chamber's vacuum≤0.1Pa, melting is proceeded by, melting in fusion process
Room vacuum satisfaction≤0.1Pa, electron gun power is 280 ~ 440kV, and bombarding voltage is 45 ± 5kW, and TC4 titanium alloys defective material is by electricity
After beamlet bombardment is molten into titanium liquid, through fusing cold bed, cold bed is refined, flow into the solidification of crystallizer crucible, then through drawing ingot system by casting
Ingot is come out of the stove after being pulled to the furnace cooling of ingot room, obtains EB ingot sides ingot；
Step 7, milling face and sawing are carried out to the EB ingot sides ingot prepared in step 6 using milling machine and sawing machine, obtain product.
The cleaning of titanium defective material surface impurity uses ball blast pickling or alkali pickling in the step one.
Titanium defective material charging box is formed by the TC4 titanium plate weldings in 5 pieces of step 2 in the step 2, and each weld seam uses argon arc
Soldering method is welded.
Fine aluminium purity >=99% of fine aluminium band volume in the step 3, the thickness of aluminium strip volume is 0.01 ~ 3.0mm.
In the step 5 by TC4 titaniums defective material according to tabular, it is bar-shaped and it is granular divided, and in cloth, tabular
With in the gap of bar-shaped titanium defective material be filled with granular titanium material.
In the step 7, unilateral milling face thickness answers >=5mm.

Shape titanium defective material, flexible and convenient operation, titanium defective material shape applicability is good；
（3）Traditional VAR meltings are the ionization electric arc for obtaining stabilization, need the gas content of certain content as ionization medium, and high
Vacuum cannot obtain stabilization ionization electric arc, therefore VAR meltings cannot realize condition of high vacuum degree melting, its melting vacuum 0.1 ~
5Pa scopes, and by 2 meltings, therefore O, N objectionable impurities elements increment are larger, and the present invention can melting once acquisition side ingot
(base), working chamber reaches 10-1 ~ 10-3 condition of high vacuum degree scopes, therefore O, N objectionable impurities elements increment are small；
（4）The high and low density inclusions of the present invention are easily removed, and during EB cold hearth meltings, the fusing of titanium liquid, refining, solidification are separated
Carry out, have enough time so that high density is mingled with dissolving or deposition is captured by cold bed scull in refining process, while also having enough
Time make that low-density is mingled with floating volatilization and dissolving is eliminated, therefore high and low density inclusions to be more easy to removal clean.
