Description
Technical field
The utility model belongs to high activity metal powder preparing technical field, and in particular to prepared by a kind of continuous smelting atomization
The device of titanium alloy fine powder at high proportion.
Background technology
Titanium elements the whole world distribution than wide, its content exceedes the 0.4% of earth crustal mass, global proved reserves about 34
Hundred million tons, content occupies the 10th in all elements, and front 10 bit is plain to be ordered as：Oxygen, silicon, aluminium, iron, calcium, sodium, potassium, magnesium, hydrogen,
Titanium.Titanium is less than steel density by 40%, and the intensity of the intensity of titanium and steel is quite, and this can improve structure efficiency.Meanwhile, titanium it is heat-resisting
Property, corrosion resistance, elasticity, elastoresistance and shaping processability are good.Titanium alloy is just applied to aircraft industry from occurring.Space shuttle
It is main, applied range airborne vehicle.Titanium is the primary structural material of aircraft, is also aerial engine fan, compressor
The preferred material of the important component such as wheel disc and blade, is described as " space metal ".Aircraft is more advanced, and titanium consumption is more, such as the U.S.
F22 forth generation machines Ti content is 41% (mass fraction), and its F119 engines Ti content is 39%, is to use Ti content at present
High aircraft.In aviation, the development of aircraft industry also promotes the development of titanium alloy to titanium alloy research origin.Titanium Alloys for Aviation
Research be always important in a titanium alloy field, active branch.
In aerospace field, have many titanium alloy parts all have labyrinth characteristic, adopt powder metallurgy more with
And the manufacture of the method such as 3D printing.Therefore, titanium alloy needs are previously prepared into powder morphology, could use in above-mentioned field.Titanium is closed
Gold has a very high activity under high-temperature atmosphere, and reacts with multiple element in the molten state, causes titanium alloy powder
Preparation it is different from the preparation method of conventional metal powder.
At present, prepare titanium alloy powder is equipped with rotary electrode method and gas atomization.Rotary electrode method is adapted to production
Granularity is the powder between 75～150 μm, due to unstability of the titanium alloy electrode bar under high speed rotation status, current nothing
Method produces powder of the granularity less than 50 μm by improving rotating speed；And powder size prepared by gas atomization can be 0～150
Adjust between μm, especially produce powder of the granularity less than 50 μm and there is advantage, be the unique production method of current titanium alloy fine powder.Should
Method is made special equipment and is produced in Europe (such as Germany) and North America (such as Canada) country.
Prepare titanium alloy powder field in aerosolization, the major way for adopting at present for：Arrange in the bottom of titanium alloy bar
Fusing heating coil, the bottom of titanium alloy bar is directly heated by melting heating coil, until titanium alloy bar is fused into liquid drop
Fall.The Jing atomizations again of the titanium alloy drop of drippage, form powder.But, the subject matter that said method is present is：Titanium alloy is from admittedly
The incubation period of state to liquid is long, will gutter down in an instant after titanium alloy melts, it is difficult to by titanium alloy liquid temperature
Degree brings up to fusing point above much higher value；In addition, the viscosity of liquid titanium alloy is also very high, it is impossible to form continuous flow, so as to affect
Follow-up gas atomization effect, causes the recovery rate of fine powder relatively low, although less than 50 μm of fine powder can be prepared, this
Specification powder proportion is generally below 40%, low production efficiency；Further, since liquid titanium alloy cannot form continuous flow,
And it is continual to be atomized the high-purity argon gas for entering, part argon gas is necessarily caused to act on drop, so as to cause argon gas
Waste, increase argon gas use cost.
