Description
Technical field
The present invention relates to aluminium alloy smelting field, specifically, it is related to a kind of compound place of Strong shear stirring aluminium alloy melt
Reason device and technology.
Background technology
The fast development of the particularly China Automobile Industry of Global Auto industry in recent years has driven auto parts and components manufacturing industry
Development, also welcome rapid growth period as the aluminium alloy wheel hub of vehicle key parts.Counted according to Chinese wheel association,
, up to 75,000,000, the amount of money is up to 38.67 hundred million dollars, and 78.86 ten thousand tons of export volume is Chinese for China's Mainland aluminium alloy wheel hub outlet in 2015
Turn into world's aluminium wheels first to manufacture and big export country.
Multiple links such as aluminium wheels manufacture is related to aluminium liquid to melt, casting, heat treatment, machining, surface treatment, wherein molten
Body treatment is first link of manufacture, and the outward appearance condition and Effect on Mechanical Properties to product are very big.At present, to aluminum melt
Reason mode, it is general using coverture is sprinkling upon into bath surface in being subcontracted in industry, refining agent is pressed into aluminum solutions with bell jar
In, then refining purification will be carried out using rotary blowing mode by carrier of nitrogen again, though during the method can eliminate aluminium liquid
Portion gas and oxide inclusions thing, but atomic hydrogen in melt processes not thoroughly with oxide inclusion, refines clean-up effect
Unsatisfactory, treated aluminum melt is 2.53~2.60g/cm through survey hydrogen to check general density2, the melt quality situation only fits
Common wheel hub is produced in symphysis, it is impossible to reach the requirement of high-quality wheel hub mechanical performance and outward appearance；Especially for the molten of high-alloying
Body, due to being easier the presence of component segregation, high-melting-point equiax crystal skewness, above processing method is for composition, particle
It is uniformly distributed treatment effect limited, coarse grains after solidifying castings crystallization；Therefore, aluminium wheels industry technology research staff needs
Develop more preferable refining aluminium fusant processing unit.
The content of the invention
The purpose of the present invention be overcome the shortcomings of it is existing to existing for aluminium alloy melt refining process, there is provided Yi Zhongke
Purifying aluminium alloy melt, refinement and the composite handling arrangement and technology for homogenizing are realized, is that a kind of Strong shear is stirred specifically
Mix aluminium alloy melt composite handling arrangement and technology.
Realizing the technical scheme of the above is：A kind of Strong shear stirs aluminium alloy melt composite handling arrangement and technology, including

The composition of refining agent is the NaCl and 20%Na of the KCl of 45% content, 35% content3AlF6；The composition of fining agent is K2ZrF6With
KBF450% is respectively accounted for, so treatment makes to contain a certain amount of ice crystal Na in solvent3AlF6Can promote solvent to the wetting of oxide with
Adsorption capacity is greatly reinforced, and the atomic hydrogen in melt and oxide inclusions are carried to the table of melt with bubble in floating-upward process
Face, improves the detergent power of solvent, fining agent K2ZrF6With KBF4Add and chemically reacted with the aluminium liquid of melting：
3K2ZrF6+13Al→3ZrAl3+4AlF3+6KF
6KBF4+3K2ZrF6+10Al→3ZrB2+10AlF3+12KF
ZrAl can be generated3With ZrB2As the heterogeneous nucleus particle of high-melting-point, the ZrAl for being formed in like fashion3With ZrB2Molten
Activity in vivo is big, good in refining effect, ɑ dendrite can be promoted more tiny, so as to play a part of crystal grain thinning；Graphite rotator immerses
The part of melt be in left-hand screw formula thread, its thread 10~15mm of depth, 15~20mm of pitch, the structure is in high-speed rotation process
Strong shear effect is played to melt, i.e., the primary phase in melt is sheared, dystectic heterogeneous nucleus particle is sheared, it is right
High density microalloy is sheared, and ɑ dendrite is tiny after the melt crystallization solidification that the pattern handling is crossed and is uniformly distributed, and eutectic composition is thin
Small uniform, casting does not exist component segregation；Scum board is installed in the both sides of graphite rotator, the cross section of scum board assumes diamond in shape, scrapes
The side of slag plate plays the role of to clash into the big foaming in melt countless small foamings, strengthens the clean-up effect of melt, scrapes slag
The corner angle of plate drive melt to rotate in graphite rotator high-speed rotation, also have shear action to melt；According to melting when using
Technological requirement, is subcontracted during 1.5-2.5kgAl-Sr-RE intermediate alloys are added, and aluminium liquid is added the transfer for being preheated to kermesinus
In bag, the dry 1.0~1.5kg of coverture of last layer is uniformly spread on aluminium liquid 500-800kg, surface, by dry refining agent 1.0
~1.5kg and dry 1.0~1.5kg of grain refiner is added in powder storage bottle, and protective cover is screwed, and graphite rotator is led to
Cross jacking system drive motor and be moved down into and subcontracted at 80~100mm of bottom, the refining clarification time is set on switch board
10.0~15.0min, 0.8~1.5m of setting gas flow2/ h, 600~800 revs/min of graphite rotator rotating speed, after refining terminates
By graphite rotator by moving on to certain altitude on jacking system, close gas, skimmed, it is whole in subcontract interior Combined Processing knot
Beam.The device favorably purifies the gas and slag inclusion in aluminium liquid, and processing procedure produces a large amount of highly dispersed heterogeneous nucleus of high-melting-point
Particle, while also having to Melt Stirring and shear effect, promotes heterogeneous equiax crystal in melt equal with high density microalloy
Even distribution, it is to avoid traditional handicraft melt treatment not thoroughly, component segregation and the problems such as coarse grains, checked at the device through surveying hydrogen
The aluminium liquid density of reason can reach 2.65m/cm2, each position ɑ dendrite of casting is tiny and is uniformly distributed, and traditional purifier phase
Than there is the effect of more preferable degassing and purifying, refinement and homogenization.
