Description
Technical field：
The utility model is related to a kind of magnesium alloy fused mass filter devices, belong to industrial magnesium alloy production field.
Background technology：
Magnesium alloy is increasingly used in the high-end necks such as aerospace weapon equipment as most light structural metallic materials
Domain.Magnesium alloy have many merits, other than light weight, also have compared with electromagnetic wave shielding it is good, damping performance is excellent and dirty
The advantages of small is contaminated, is known as " 21 century green material ".
The production and processing of magnesium alloy materials at present is still based on casting, and there is certain casting flaws, it is impossible to as
Large-scale load-carrying member uses.Even across large plastometric set, it is loose to eliminate some holes, but cannot still completely eliminate base
Flux in body is mingled with and oxide slag inclusion, and causing component, there are uncertain hidden danger, these castings during being on active service
The industrialization method of smelting that the generation of defect is derived from current magnesium alloy after all is not perfect caused.The activity of pure magnesium compared with
Height easily forms oxide in fusion process, and in order to avoid the generation of oxidation, common way is covered in bath surface addition
Lid agent carries out gas shield.Under ordinary meaning, so-called coverture is the powder containing fluoride, can be become at high temperature
Oily liquids floats on bath surface, blocks contact of the oxygen with melt, and then prevent from aoxidizing.So-called gas shield, mostly contains
The high density inert gas of fluorine, the process of blocking oxide.For coverture, other than containing fluoride, also containing a large amount of
Chloride, it is most important for magnesium chloride, rare earth-iron-boron can be contained under the conditions of some, these powder in dispersion process inevitably
It will appear caking phenomenon, be used as during subsequent alloying smelting and be more significantly mingled with；And gas shield is carried out
Melting, at present its application range it is too small, cannot accomplish to cover comprehensively in magnesium alloy production process is commercialized, in addition, right
It is higher than 800 DEG C of magnesium alloy in smelting temperature, the effect of gas shield will significantly reduce, and aoxidizing will continue to occur.It follows that
Since the oxide inclusion or flux that occur in magnesium alloy smelting are mingled with unavoidably, then how to improve the matter of magnesium alloy ingot
Amount will be the following key factor for improving magnesium alloy enterprise competitiveness, while be also the only way which must be passed that magnesium alloy expands application.
The sublimate of magnesium alloy fused mass is always the direction that magnesium alloy enterprise makes great efforts to have in mind, most commonly addition refining
The method of agent, the largest benefit of this method can exactly simplify smelting technology, in fact be also that current magnesium alloy enterprise commonly uses
One of method, but be using the greatest problem of refining agent, refining agent is combined in itself with impurity belongs to probabilistic event, always
Will appear certain probability scenarios causes refining agent that cannot be come into full contact with impurity, so it is necessary work to increase stirring dynamics,
However increase oxygen again in stirring and contacted with air, more impurity generations are had, in addition, what refining agent was generally mingled with flux
Removal effect is preferable, and the removal effect being mingled with to oxide is general, so pure using agent method raising alloy melt is refined
Way has apparent limitation.
According to the difference of capability of industrialization, the melt sublimate method that some magnesium alloy enterprises use is mainly using multistage
The mode of tank, every grade of flow container all extract the liquid at the top of melt, and slag is stayed in bottom.The great advantage of this method is exactly can be with
Stablize quick production, improve production efficiency, but after the ingot casting that melting is obtained reaches certain amount, prime smelting pot is necessary
It is replaced, and other grade of smelting pot must stop producing at this time, therefore, this method is suitble to the production of large-scale magnesium alloy enterprise.
Another more common method is exactly using filter forced filtration melt, and potsherd is general common Jie
Matter is typically include MgO, SiO2 or ZrO etc., these potsherds show that there are many apertures, when melt is through small holes, large scale
Impurity can be blocked, after the melt for filtering certain volume, replace potsherd.However, since potsherd belongs in itself
Brittleness material, since the shock of melt is susceptible to the phenomenon that potsherd is broken in filter process, into melt after formed it is new
Impurity, therefore, in order to reduce the generation of the above situation, need to optimize current ceramic chip structure.
Utility model content：
The utility model is to provide a kind of magnesium alloy fused mass filtering dress to solve the above-mentioned problems of the prior art
It puts.
There is technical solution used by the utility model：A kind of magnesium alloy fused mass filter device, including setting up and down two
Layer steel wire, spaced two layers of stainless steel plate between two layers of steel wire are spaced between two layers of stainless steel plate
Two layers of stainless steel grinding dust of setting, the porous ceramics between two layers of stainless steel grinding dust, the steel wire are tightly attached to stainless steel plate, no
Rust steel plate is tightly attached to stainless steel grinding dust, and stainless steel grinding dust is tightly attached to porous ceramics.
Further, the hole density of the steel wire be 1000 mesh, material be 304 stainless steels, a diameter of 150mm.
Further, the stainless steel plate material be stainless steel containing Cr, hole density be 25 mesh, thickness 5mm.
