Description
Technical field
The invention belongs to aluminum alloy fiber manufacturing field, a kind of continuous aluminum alloy fiber of micron order super-strength is related generally to
Manufacturing method.
Background technology
Aluminum alloy fiber belongs to industry newly developed in recent years, and due to its good application performance, it is heavy increasingly to embody its
It is worth, with the raising of the development and people's living standard quality of society, required precision higher and higher to product requirement standard
Also higher.
There are three types of the manufacturing method of aluminum alloy fiber is summed up：Meltblown, hubbing and cutting method.Meltblown it is basic
Principle is to set there are one the aperture of adjustable flow velocity, give liquid level METAL HEATING PROCESS to molten condition at the bottom of liquid metal vessels
Apply pressure, forces molten metal to spray rapidly or throw away and form metallic fiber, liquid is made using the agent of chemism Quench or magnetic field
Stream is stablized and its solidification is promoted to form fiber；Hubbing is divided into as single strand drawing and bundle drawing method, wherein single strand drawing method product
Surface is smooth, accurate size, but tedious process, and the production cycle is long, of high cost, is mainly used for certain special dimensions, such as high-precision
Sieve etc.；Though bundle drawing method reduces cost, in the prior art the manufacturing process of aluminum alloy fiber, need aluminum-alloy wire collection
It gets one's things ready and carries out drawing again in auxiliary extraction loop bar, loop bar has fixed length, therefore aluminium alloy filament also can only be one section one section
Processing, can not Continuous maching, production efficiency is not high, and fineness does not reach requirement yet, and product surface quality and drawing diameter are difficult to
Ensure；Cutting method is using solid metallic as raw material, and with Tool in Cutting at Soft flocks, method is simple, with short production cycle, cost
It is low, but be difficult to obtain the smooth long fibre in section；Meltblown and cutting method are larger mainly for the production of 30um or more specifications
Staple fiber cannot produce superfine continuous aluminum alloy fiber；Meltblown production efficiency is higher, but surface oxide layer is thicker, right
The heat conduction of aluminum alloy fiber, electric conductivity have large effect；Cutting method production efficiency is relatively low, shorter only several lis of fibre length
Rice.
Invention content
Goal of the invention：The purpose of the present invention is to provide a kind of manufacturers of the continuous aluminum alloy fiber of micron order super-strength
Method, the aluminum alloy fiber that the present invention produces have the advantages that string diameter uniformly, can continuous production, at low cost, efficiency is higher, from
And so that compression ratio is matched with drawing speed and realize that uniform fiber diameter, the coefficient of variation are small.
Technical solution：In order to reach foregoing invention purpose, the present invention is specifically achieved like this：A kind of micron order is superpower
The manufacturing method for spending continuous aluminum alloy fiber, includes the following steps：
（1）Cladding：Using aluminium alloy rod as raw material, coated with copper strips after the oxide layer on surface treated removal aluminium alloy rod surface；
（2）It stretches：Copper-clad aluminum alloy bar after will be coated is drawn into aluminium alloy wires, is then cleaned with copper surface cleaning liquid dry
After net aluminium alloy wires, then will be in the aluminium alloy wires after-combustion to drum that cleaned up；
（3）Compound assembling：Several aluminium alloy wires are positioned on tension pay-off creel simultaneously, are then coated with copper strips；
（4）Boundling connects withdrawing roll and rolls：Aluminium alloy wires after compound assembling is exhausted, is compressed, even withdrawing roll rolls, until copper strips packet
Coating is adjacent to aluminium alloy wires；
（5）Repeat step（3）And step（4）More than primary, aluminum alloy fiber is obtained；
（6）Surface treatment：Aluminum alloy fiber is positioned on copper aluminium defiber, the copper on aluminum alloy fiber surface is removed and rinsed
Totally；
（7）Drying：The aluminum alloy fiber of rinsed clean is carried out to dry to obtain aluminum alloy fiber finished product.
Most sliding friction, is become rolling friction by the production technology that even withdrawing roll rolls, and greatly reduces friction resistance
Power is, it can be achieved that high speed drawing.Boundling even draws the advantage of roll process to be to allow that even withdrawing roll Increased Speed of Rolling Mill, can improve production capacity and set
Standby utilization rate, reduces and shuts down mould replacing time, reduces breakage ratio, improves out line mass：Outlet radial direction even tissue, mechanical performance carry
Height, the unlubricated powder in surface, spatter property improves, energy saving, saves manually, need not anneal, and shortens the process-cycle；Improve environment, subtracts
Few wire drawing powder uses, and workshop condition is clean.
Further, the step（3）It is middle when being coated with copper strips, control the filling of aluminium alloy wires in copper strips clad
Amount is 80%~85%.
Further, the loading of aluminium alloy wires is 85% in the copper strips clad.
Further, it is, the step（4）In, it is described exhaust, compression, even withdrawing roll roll for carry out successively it is big draw,
Middle drawing and rolling are drawn.
Further, control compression ratio is 8%~20% when even withdrawing roll rolls.When copper strips clad is adjacent to aluminium alloy wires,
Guarantee thoroughly empties air, to ensure that every wire rod in bulk keeps relatively parallel.
Further, control compression ratio is 20% when even withdrawing roll rolls.
Further, in the surface treatment step, copper is removed using concentrated nitric acid, then neutralizes and rinses, until pH
It is 7 ± 0.3.Surface treatment be remove aluminum fiber in copper, due to having used concentrated nitric acid in the process, thus carry out neutralize with
Rinsing, it is 7 ± 0.3 to be eventually held in pH.
Further, with supersonic wave cleaning machine on-line cleaning when the rinsing.It is most important when cleaning aluminum alloy fiber,
Supersonic wave cleaning machine on-line cleaning is first used, speed during which should be controlled and not exceed regulation, is avoided to aluminum alloy fiber cleaning not
Totally surface is caused to be stained.
Further, in the baking step, first naturally dry to surface is without water droplet；It is dried again into glass sunlight house, control temperature
Degree is 45 ± 2 DEG C, 10 ± 3h of time.
Beneficial effects of the present invention：Compared with traditional technology, the invention has the advantages that：
1, the present invention need not make annealing treatment, and shorten the process-cycle；
Most sliding friction, is become rolling friction, greatly reduces frictional resistance by the 2, production technology that even withdrawing roll rolls,
High speed drawing can be achieved；
3, boundling even draws the advantage of roll process to be to allow that even withdrawing roll Increased Speed of Rolling Mill, can improve production capacity and utilization rate of equipment and installations, subtract
Mould replacing time is shut down less, is reduced breakage ratio, is improved out line mass：Outlet radial direction even tissue, mechanical performance improve, surface Wu Run
Smoothers, spatter property improves, energy saving, saves artificial；Improve environment, reduces wire drawing powder and use, workshop condition is clean.
