Description
Technical field
The present invention relates to aluminium and its alloy purification refining treatment technical field, and in particular to a kind of villaumite fusion refining agent
Preparation method.
Background technology
In the fusion process of aluminium and its alloy, melt quality and environmental problem are the important issues of aluminum i ndustry.These are all
There is substantial connection with the handling process of melt and the flux for being used.
Often inevitably containing alkali metal impurities such as higher sodium, calcium and lithiums in aluminium ingot.Inside plants go back feed back
And aluminium waste is generally mixed with nonmetallic inclusion, organic material and steam.These alkali metal, nonmetallic slag inclusion and steam to aluminium and its
The casting of alloy and follow-up manufacturing procedure can cause serious quality problems.So before casting, it is necessary to using refining agent
Purefying process is carried out to aluminium water -- except alkali metal, removal of impurities degasification.
Removing alkali metal needs, by chemical reaction, alkali metal atom to be cemented out, and in terms of removal of impurities degasification, can be with
Absorption principle is swum etc. realizing by bubble.So, for the higher aluminum melt of alkali metal impurity content, need using reaction
The stronger refining agent of property comes purefying, such as carbon trichloride (C2Cl6), chlorine etc..Used as refining agent, carbon trichloride has non-
Normal good refining effect.But unpleasant stench can be produced using carbon trichloride, environment is polluted, the health of workman is affected.Chlorine
Once popular as refining agent, but, the airborne release that substantial amounts of chlorine and hydrochloric acid can be caused using chlorine refining.And it is near
To find, logical chlorine may form a kind of carcinogenic substance in aluminium liquid -- dioxin (Dixon), serious environmental pollution is caused,
So carbon trichloride, chlorine are gradually eliminated as refining agent.
With MgCl2Fusion refining agent for base is to substitute the ideal chose that chlorine is refined.This refining agent has removal concurrently
Alkali metal, remove oxide and be mingled with and the comprehensive function such as dehydrogenation, but free from environmental pollution.MgCl in refining agent2In aluminium water
Liquid MgCl is dissolved into rapidly2, there is displacement reaction with Na, Li and the Ca in aluminium water：
MgCl2+2Na→2NaCl+Mg
MgCl2+2Li→2LiCl+Mg
MgCl2+Ca→CaCl2+Mg
NaCl, LiCl and CaCl of generation2Surface is floated to, so as to reach the purpose for removing Na, Li and Ca.The opposing party
Face, oxide inclusions and the refining agent collision being melted in aluminium water, and be bonded in molten refined agent, interfacial characteristics occurs therewith
Change, these Slag inclusions are no longer by aluminium water-wet.Then, the slag inclusion composition granule for being melted refining agent wetting floats, and incorporates aluminium water
In the slag on surface, the purpose of slagging-off has been reached.
United States Patent (USP) US4099965 discloses a kind of MgCl2- KCl fusion refining agents, containing 20～40%KCl, 60～
80%MgCl2.Good refining effect is achieved, in foundry's chlorine usage amount is reduced, serves positive role.
A kind of MgCl has been opened in application for a patent for invention 20151058357742- NaCl and MgCl2- NaCl-KCl villaumite fusions
Refining agent.At present, the preparation method of villaumite fusion is by commercially available MgCl2, the villaumite such as NaCl, KCl mix, then
Load heating fusing in irony or graphite crucible, then liquation cooled and solidified is formed villaumite fusion, finally by the villaumite of solidification
Fusion is broken into particle or powder.In actual production, programming rate is slower, can produce when villaumite is close to fusing substantial amounts of
Tobacco, the smell is awful.
Presently commercially available MgCl2One of source be the byproduct for producing titanium sponge or sponge zirconium.Titanium sponge or sponge zirconium
Production technology similar.Technological process is：Titanium material or the chlorination of zirconium raw material are generated thick TiCl first4Or ZrCl4, then refine
Obtain smart TiCl4Or ZrCl4.In reduction distillation operation, magnesium metal, smart TiCl is added4Or ZrCl4With gold at 800～1000 DEG C
Category magnesium carries out reduction reaction and obtains spongiform Titanium or zirconium and magnesium chloride, separates titanium sponge or sponge zirconium with vacuum distillation,
So as to obtain pure titanium or pure zirconium and liquid MgCl2.Liquid MgCl2Temperature be 800～1000 DEG C, as byproduct, discharge reaction
Stove.The liquid MgCl of discharge2Or magnesium metal and chlorine is isolated through electrowinning process, or directly cool down, as anhydrous chlorine
Change magnesium to market sale.
On the one hand, high-temperature liquid state magnesium chloride will be cooled down, and bulk magnesium chloride will be crushed.On the other hand, villaumite fusion is prepared
When villaumite is heated.If other component fusings of villaumite fusion are prepared villaumite and are melted by the high temperature using liquid magnesium chloride
Compound, then can save refrigerating work procedure, the broken process of bulk magnesium chloride and the reheating operation of high-temperature liquid state magnesium chloride.Using height
Warm MgCl2Heat fusion other components, firing rate is fast, and all components instant melting greatly reduces fusing
The tobacco produced during villaumite.The energy was both saved so, the production cycle had been shortened again, production cost has been reduced, and is reduced
Environmental pollution, significant.
Content of the invention
The technical problem to be solved in the present invention is, it is proposed that a kind of preparation method of villaumite fusion refining agent, the method
