Description
Technical field
The present invention relates to a kind of production technology of secondary metal, and in particular to a kind of production technology of secondary aluminium.
Background technology
The production technology of secondary aluminium mainly has following processing step：Waste aluminum processing, manual sorting, aluminium scrap material be pre-prepared,
Dispensing, melting, chemical examination and pour into a mould and produce last finished product.In the prior art be particularly fusion process in stirring technique exist with
Lower problem：1st, mixing plant purchase cost is big, causes the cost of whole secondary aluminum production process high；2nd, operation is by very big office
Limit, is stirred in smelting furnace, it is difficult to penetrate into each position, because the position of stirring is limited to, and time of stirring and to aluminium liquid
Mixing evenness be all affected；3rd, it is larger to the scaling loss degree of aluminium liquid, scaling loss degree up to 8~10%, have influence on it is overall go out aluminium rate,
Raw material are wasted, greatly reduce yield；Worker receives scorching for flame for a long time when the 4th, stirring, and has very big potential safety hazard.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of regeneration aluminium production process based on Vibratory Mixing technique,
Can uniform stirring aluminium liquid, reduce the scaling loss degree to aluminium liquid, improve out aluminium rate and yield, and safety, cost are low.
In order to solve the above technical problems, the regeneration aluminium production process based on Vibratory Mixing technique of the present invention, including aluminium scrap
Expect pre-prepared, dispensing, melting, chemical examination composition and cast cast secondary aluminium product, described melting process include to the end
Following processing step：
A, the aluminium scrap material after dispensing is fitted into smelting furnace；
B, melting is carried out at 650~760 DEG C, is stirred simultaneously, stirring is specially to use air compressor, described air
Compressor connects vibrating head one end by pipeline, and the other end of described vibrating head stretches into the burner hearth of smelting furnace, opens during stirring
Air compressor, oscillating rod is driven to be stirred in burner hearth internal vibration, mixing time is 10~15min, is fed after the completion of stirring；
C, it is repeated twice according to the technique in step B, i.e., is stirred, feeds, stirs, feeds successively；
D, according to the stirring technique stirring in step B once；
E, according to the stirring technique stirring in step B once, then it is sampled successively and adjusting component process；
F, according to the stirring technique stirring in step B once, then carry out refining degasification process, then take surface slag off；
G, according to the stirring technique stirring in step B once, melting is completed, obtains melting aluminium liquid.
Described air compressor index parameter is in stepb：Pressure at expulsion is 0.3~0.9MPa, rated discharge amount
For 3~4m3/min, rated speed 1000r/min.
Described oscillating rod is seamless steel pipe in stepb, and a diameter of 80~140mm, pipe thickness is 5~10mm, long
Spend for 4~8m.
Described smelting furnace is the horizontal type smelting furnace of one end open in stepb, and fire door right opposite is provided with thermal insulation board.
In the stirring carried out successively, charging, stirring, charging described in step C, after once stir and feed between enter
Row dedusting ash disposal is handled.
Described dedusting ash disposal is handled：Smelting furnace is by being sequentially connected suspended hood, cyclone dust removal machine, bag-type dust
Machine, blower fan and aiutage, dust is excluded.
The technological merit of the present invention is embodied in：Improvement of the present invention to the stirring technique in the production technology of secondary aluminium and excellent
Change, be connected using air compressor by pipeline with smelting furnace burner hearth, and stirred using vibrating head, and smelting temperature, stir
Mix number, stirring order and mixing time all to optimize and adjust, solve mixing time length in the prior art, to aluminium liquid
Scaling loss degree it is larger, scaling loss degree up to 8~10%, have influence on it is overall go out aluminium rate, raw material are wasted, the problem of yielding poorly, there is provided a kind of
The production technology of secondary aluminium, can uniform stirring aluminium liquid, substantially reduce the scaling loss degree to aluminium liquid, improve out aluminium rate and yield, separately
Outside, labour is saved, and stirring operation is convenient, flexible, it is found which position stirring is uneven, can be by vibrating head neatly
It is moved to that position so that stirring is more uniform, and then aluminium liquid is heated evenly, and improves last aluminium liquid and casts out
The quality of secondary aluminium product；The stirring technique of the present invention reduces equipment acquisition cost.The present invention uses horizontal type smelting furnace, and
Smelting furnace open at one end right opposite is provided with thermal insulation board, improves the stirring environment of worker, prevents that individual from being scorched by flame,
Reduce the amount of labour.
