Description
Technical field
The utility model is related to a kind of siphon transfer pipe, specifically a kind of aluminium alloy purification siphon for Die Casting
Transfer pipe.
Background technology
Die casting refers to molten alloy filling mold cavity under high pressure, high-speed condition, and be cooled and shaped under high pressure
Casting method.With developing rapidly for the fields such as auto industry, in modern manufacturing industry product to quantitatively, complicate, it is accurate
Change, lightweight, energy-saving, the requirement of greenization manufacturing technology are improved constantly, and die casting has turned into most widely used, hair in casting technique
The fastest non-ferrous alloy precision parts forming technique of exhibition.Clean liquid metal be obtain high-quality die casting premise and
Ensure, therefore, in fusing and cast, melt obtains totally enclosed type protection to prevent melt is mingled with from entering die casting die cavity with gas,
Avoid causing cast properties reduction because being mingled with the various defects produced with gas in die casting or even scrap.
Increasingly increase as the application in non-ferrous metal structure material, especially auto industry, generate substantial amounts of useless
Material, the waste material particularly produced in die casting is particularly more.It is necessary that these waste materials are returned based on consideration economical and environmentally friendly
Receive and recycle, so as to substantially increase the technical difficulty of melt refining purification.In die casting non-ferrous alloy fusion process, in alloy
The gas (wherein 80~90% be hydrogen) of existing dissolving in liquid has compound field trash again, because furnace charge is unholiness and fusion process in
Aoxidize the existing diecasting alloys oxide of melt field trash (magnesia, which is mingled with, in diecast magnesium alloy about account for 80%) produced, add
Flux chloride and fluoride etc. are entered, the intermetallic compound kind also including Fe-riched phase is mingled with.Field trash it is general with
The form of film-form, particle shape or race's shape is remained on the matrix or crystal boundary of Mg alloy castings, at the same because hydrogen precipitation not only
Cause field trash surface multiple crackses, pore, and shrinkage porosity defect of contraction cavity can be formed in casting.It is existing test result indicates that,
The class harmful substance of this in aluminium alloy two also produces synergy, and increase disperse inclusion content can prevent the dehydrogenation from aluminium alloy
Diffusion process.Gas in field trash and melt not only reduces the processing performance, mechanical performance and corrosion resisting property of diecasting alloys, and
And often due to field trash is wrapped in substantial amounts of alloy liquid and causes the loss of alloy, it is therefore, necessary during diecasting alloys melting
Refinery by de-gassing purification is carried out to melt to remove the field trash and gas that are harmful in aluminium alloy.
The method of field trash can be divided into flux refining and the major class of non-flux purification two in conventional removal magnesium alloy.Flux is net
Chemical industry skill is because of dust removal rate height, cost is low, easy to operate and turns into the purification technique generally used in diecasting alloys purified treatment,
But flux refining is mingled with there is also metal loss increase, flux, is unable to the deficiencies such as degasification.Non-flux purification method at present should
With being most widely gas rotating blowing process, mechanical filter method, ultrasonic purification method, electromagnetic purification method, vacuum purification method etc..Knot
The composite purification technology for closing flux refining and non-flux purification process characteristic and developing is purified as high-quality die-casting alloy melt
The major technique of processing, general diecasting alloys founding purified treatment be accomplished by it is closed, rise and do not carry out in the twin furnace of same-action：
Melting furnace is used to feeding, melt and collect slag refining degasification, holding furnace for keep the temperature of pure aluminium alloy, stable components with
It is easy to die casting (can also be using melting furnace, refining except three furnace structures of steam stove and holding furnace are carried out at diecasting alloys founding purification
Reason).At this moment, how the aluminium alloy in melting furnace is transferred in holding furnace and ensures that the degree of purity of aluminium alloy just turns into die casting and closed
The key technical problem solved is needed in golden purified treatment, traditional way is to connect two stoves by the pipe with filtering, but
This method can not eliminate the mutual crossfire of aluminium alloy in two stoves, so as to be difficult to ensure that the degree of purity of aluminium alloy in holding furnace, together
When connecting tube in filter replacing it is also extremely difficult.

The parabola shaped cavity structure of feed liquor end face of refractory ceramics filter stick can guide liquid to be moved to cavity bottom, from
And sealing function can be played, alloy liquid is avoided to a certain extent from the outlet of refractory ceramics filter stick and siphon transfer pipe
Junction leaks outside between section；When alloy liquid flows from the top down, the feed liquor end face of refractory ceramics filter stick is parabola shaped
Cavity structure causes the impurity particle not only in the vertical direction, and also being flowed in a lateral direction on filter stick surface
The active force of aluminium alloy stream, being so deposited in the impurity of filter bores will repeatedly be rushed under the horizontal force of aluminium alloy stream
Brush, impurity will not be blocked in filter bores, avoid filtering hole plug to greatest extent, improve the efficiency of aluminium alloy filtering.
Preferably, the aperture of the filter bores is
In order to be incubated to the alloy solution in siphon transfer pipe, heating is sequentially installed with outside the siphon transfer pipe
Layer, heat-insulation layer and fixed zone of heating, the fixed bed of heat-insulation layer.
The utility model uses simple structure, the diecasting alloys that effectively will can be tentatively filtered by screen pack from melting furnace
Solution, is removed oxide inclusion by the in-depth filtration purification of filter stick in siphon pipe, it is ensured that be transferred in holding furnace and press
The degree of purity of cast alloy solution, improves the quality of alloy die cast production；When not shifting aluminium alloy, heater stop works, rainbow
Aluminium alloy is flowed back in respective stove respectively in suction pipe, while the replacement operation of filter stick is also more convenient in siphon pipe.This practicality is new
The refractory ceramics filter stick structure of type not only acts as preferable sealing effectiveness, and can be prevented effectively from the blocking of filter bores.
