Abstract
The present invention relates to a kind of method of purification of rafifinal, by the way that the aluminium liquid of melting is injected in crucible, and is heated by crucible, make to be arranged on the crystallizer in the middle part of crucible to rotate in crucible inner-spiral type, aluminium liquid in crucible is stirred, and cooling water is constantly passed through into crystallizer, carries out crystallisation by cooling.The advantage of the invention is that：Aluminium liquid is maintained at certain temperature by the heater strip of crucible outer surface, and cooling water is continuously added into crystallizer, aluminium liquid will go out the high crystal of purity in crystallizer surrounding crystalline；This technique is simple, and production efficiency is high；Meanwhile the purity of aluminium may be up to 99.9999% after purification.
Description
Technical field
The present invention relates to the purification mode of metallic aluminium, more particularly to a kind of method of purification of rafifinal.
Background technology
Although the country has enterprise in trial production or large-scale production rafifinal, compared with external type of industry, have compared with
Big gap, multi-party deficiency be present：1. equipment and technique are relative complex, it utilizes multidisciplinary art, makes cost of investment excessive,
And manipulation is grasped in inconvenience；2. it is unsatisfactory to discharge impurity efficiency, qualified products are can not produce；3. energy consumption is higher, up to 15000KWH/
More than ton, disagreed with national energy-saving emission reduction policy, although decreasing at present, also there are ten thousand degree or so；4. although production is produced
Product, but quality is still unstable, domestic user is not used.
The content of the invention
The purification side of the good rafifinal of simple and refining effect the technical problem to be solved in the present invention is to provide a kind of technique
Method.
In order to solve the above technical problems, the technical scheme is that：A kind of method of purification of rafifinal, its innovative point exist
In：Comprise the following steps：
（1）The aluminium liquid of melting is injected in crucible, and heated by crucible, makes aluminium liquid insulation at 680 DEG C；
（2）Make to be arranged on the crystallizer in the middle part of crucible to rotate in crucible inner-spiral type, the aluminium liquid in crucible is stirred, not
Break and cooling water is passed through into crystallizer, carry out crystallisation by cooling.
The advantage of the invention is that：The method of purification of rafifinal of the present invention, aluminium liquid is set to be maintained at certain by crucible heating
Temperature, and cooling water is continuously added into crystallizer, aluminium liquid will go out the high crystal of purity in crystallizer surrounding crystalline, and lead to
Continuous rotary crystallizer is crossed, increases the flowing of solid liquid interface, improves the diffusion effect of solute；This technique is simple, and produces effect
Rate is high；Meanwhile the purity of aluminium may be up to 99.9999% after purification.
Embodiment
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among described scope of embodiments.
Embodiment 1
The method of purification of the rafifinal of the present embodiment, comprises the following steps：
（1）The aluminium liquid of melting is injected in crucible, and heated by crucible, makes aluminium liquid insulation at 680 DEG C；
（2）Make to be arranged on the crystallizer in the middle part of crucible to rotate in crucible inner-spiral type, the aluminium liquid in crucible is stirred, not
Break and cooling water is passed through into crystallizer, carry out crystallisation by cooling；
（3）Terminated through 4 hours, crystallization taking-up is cooled down, is cooled to 42 DEG C, take out crystallization ingot, from the tail of crystallization ingot
Portion removes the 1/4 of crystallization ingot weight, the aluminium ingot purified.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The skill of the industry
For art personnel it should be appreciated that the present invention is not limited to the above embodiments, described in above-described embodiment and specification is explanation
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
