Description
Technical field
The invention discloses a kind of method utilizing Ovum crusta Gallus domesticus carrier to prepare refining agent, belong to refining agent technology of preparing neck
Territory.
Background technology
Known, along with growing in intensity of aluminium alloy processing industry competition, in order to reduce cost, when casting, foundry returns
Accounting for raw-material ratio more and more higher, the foundry returns that even some oxidative impurity levels are higher is also frequently used, but,
Owing to producing during aluminium alloy, molten aluminium alloy when solidification, the hydrogen molecule formed by hydrogen atom in aluminum liquid can and
Non-metallic inclusion forms bubble, and in aluminum liquid, impurity and the gas of the overwhelming majority both are from answering in foundry returns, i.e. foundry returns
With greatly improving the content of oxidation impurities in aluminum liquid, thus cause the aluminium alloy castings made can there is certain defect,
Therefore, in view of when aluminium alloy smelting, in aluminum liquid, the increase of oxidative impurity levels not only influences whether the performance of product, and right
Conforming product rate also has a significant impact, and impurity content particularly requires strict product, the aluminum-alloy wheel of as bright in finish turning,
Piston, engine cylinder-body etc., so, the refine purified treatment of aluminum liquid is just become one of requisite operation；But,
In actual application, because traditional method of refining, as spray refining, filter refine etc. use be all there are refining agent not under
Heavy, the most floating on molten aluminium alloy upper strata phenomenon, which results in and also need to manually carry out being stirred continuously just to complete refine,
Its not only effect poor, and the amount of labour is relatively big, so, in the case of current recruitment cost improves day by day, the simplest and
Remove one of difficult problem having had become as puzzlement industry development of the oxidation impurities in aluminum liquid the most efficiently.
The conventional production process of refining agent is to use furnace cupola fritting method and furnace melting method, both sides the most both at home and abroad
Method be all by putting in high temperature furnace after fusing after the mixing of the natural slag making materials such as Calx, bauxite, dolomite, Silicon stone, cooling broken
Prepare after broken.Aforesaid way need to consume the natural resources such as substantial amounts of Calx and bauxite, and power consumption is big, and production cost is high, therefore
The price making fritting refining agent is the highest, considerably increases the smelting cost of iron and steel enterprise, produces simultaneously after ladle furnace refining
Raw a large amount of refining waste residues also result in the severe contamination of environment and a large amount of wastes of resource.
It addition, the refining agent used in traditional aluminium alloy manufacture process, the electric conductivity of finished product, heat conductivity, resistance to can be caused
Corrosivity is strong, and the degree of porosity in the alloy-steel casting produced is higher, can produce seven apertures in the human head cast(ing) surface is many, aoxidize miscellaneous
The ratio of thing is the highest, have impact on the performance of alloy-steel casting, and the product during refine has penetrating odor, for work
Make personnel's harm very big.
Summary of the invention
The technical problem that present invention mainly solves: for current conventional production process during preparing refining agent, inhales
The ability of attached field trash is the highest, and cost is high, and the degree of porosity in the alloy-steel casting produced is higher, at cast(ing) surface
How can produce pore, the ratio of oxidation foreign material is the highest, the problem that have impact on the performance of alloy-steel casting, it is provided that a kind of with egg
Shell is carrier, carbonization after first processing its surface, and the Ovum crusta Gallus domesticus after carbonization is put into potassium chloride, magnesium chloride, sodium sulfate, chlorination
Zinc, sodium nitrate solution in soak absorption, dry together with solution after absorption, by drying object and calcium fluoride, pyrophillite, diatom
The method that soil, flyash and rare earth mixing and ball milling obtain refining agent, the method refining agent auxiliary agent after Ovum crusta Gallus domesticus adsorbs
It is possible not only to improve the stability of auxiliary agent, and the ability of Ovum crusta Gallus domesticus dross inclusion adsorption is high, low cost, prepared refining agent chemistry
Good stability, slag making performance is good, and degasification, purification capacity by force, have wide market prospect.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
