Description
Technical field
The invention belongs to powder metallurgical technology, and in particular to a kind of device of raising titanium alloy powder yield rate.
Background technology
The present invention is powder preparation principle with plasma centrifugal atomization, and the method is rotated high speed by plasma gun
Blank carries out centrifugal atomizing, and atomization is carried out along the conical surface, powder good sphericity and can largely reduce powder hollowness, but
This powder preparation method, considers not enough for the crystallization mechanism in melts of titanium alloy droplets mixing atmosphere cooling procedure, and makes
Into relatively low powder product rate.
The present invention is with Russian Federation's patent《Powder Preparation equipment》The powder manufacturing apparatus structure of interior introduction is equipment prototype.But this
Plant device structure and there is clearly disadvantageous part in titanium alloy powder preparation process：The equipment is atomized the main cold of indoor gas
But mode is lowered the temperature by spray chamber cooling wall, and gas apart from the region of spray chamber cooling wall certain distance with hot
Stagnate, and cause the efficiency reduction of the drop for flying away from convection current cooling in flight course is centrifuged, such cooling degree is closed to titanium
The production at bronze end is substantially not enough, and the insufficient powder of more cooling is got on spray chamber with high speed can aspherical powder
Grain, so as to reduce the rate of output of finished powder.
Because the thermal conductivity of nickel base superalloy is higher, its cooling degree will more fully, and yield rate is higher, therefore on
The method of stating is used primarily in the production of Ni-base Superalloy Powder.If the method is applied in the preparation of titanium alloy powder, must fill
Divide and consider prepared by titanium alloy powder the characteristics of.
When prepared by titanium alloy powder, sheet aspherical powder is likely to form in fusion process, this is mainly due to atomization
Chamber size and structure constraint, powder do not reach sufficiently cool condition in flight course, high-speed cruising and cool down insufficient
Powder particle with atomization locular wall clash into after pattern change.Although spray chamber water-cooling wall is deposited to the cooling for being atomized indoor gas
, but heated gas is stagnated apart from the region of spray chamber water-cooling wall certain distance, the temperature drop of cooling medium is inadequate, and
And due to titanium alloy thermal conductivity compared with nickel alloy compared to low, drop cool down deficiency in flight course and cannot be fully crystallized, with
Atomization locular wall can occur plastic deformation after clashing into, and in follow-up screening, the powder of this kind of pattern is screened out, and reduces qualification rate.
The content of the invention
To overcome above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of raising titanium alloy powder yield rate
Device, the present invention strengthens the work of spray chamber gas temperature drop to reach by introducing a set of single gas circulation cooling system
With.The temperature of gas in whole fusion process is reduced to gas cooling in cyclic process to carry out supplement cooling；With knot
Structure is simple, the characteristics of improve powder product rate.
To achieve the above object, the technical solution adopted by the present invention is：A kind of device for improving titanium alloy powder yield rate,
Spray chamber is included, spray chamber top is connected by valve one with filter；Filter is connected by valve two with cooling device；
Cooling device is connected by valve three with air accumulator；Air accumulator is connected by valve four with blower fan；Blower fan passes through valve five and mist
Change room bottom to be connected.
The beneficial effects of the present invention are：
In inert gas, using plasma jet fusing rotary billet end, Titanium Powder is being produced using plasma atomization
During end, by introducing the inert gas circulating cooling system independently of plasma gun, supplement cooling is carried out to spray chamber, led to
Crossing the circulatory system will send spray chamber back in spray chamber after heated gas cooling.This method can be by powder in-flight
Last particle supplement cooling, so as to play a part of to reduce aspherical powder quantity, can improve powder product rate.
Brief description of the drawings
Fig. 1 is that spray chamber of the present invention supplements cooling gas circulation theory figure.
Specific embodiment
Structural principle of the invention and operation principle are described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of device of raising titanium alloy powder yield rate includes spray chamber 1, and the top of spray chamber 1 passes through
Valve 1 is connected with filter 3；Filter 3 is connected by valve 24 with cooling device 5；Cooling device 5 by valve 36 with
Air accumulator 7 is connected；Air accumulator 7 is connected by valve 48 with blower fan 9；Blower fan 9 is connected by valve 5 10 with spray chamber bottom.
Operation principle of the invention：
The circulatory system is vacuumized together with equipment, in fusion process, gas under the air-extraction function of blower fan 9,48 dozens, valve
Open, valve 1, valve 24 and valve 36 from spray chamber 1 along pipeline through opening enter storage through filter 3 and cooling device 5
In gas tank 7, and the gas after cooling down returns to spray chamber in the presence of the air-supply of blower fan 9, and the gas in spray chamber is supplemented
Cooling, closes cooling device 5 after the completion of melting, and blower fan continues to run with closing blower fan 9 after residual body is discharged, and closes all
Valve.
