Description
Technical field
The present invention relates to the magnesium alloy processing industry, particularly relate to a kind of used for magnesium alloy nanometer flux.
Background technology
Magnesium alloy is the fastest light alloy of our times development and application, have that light specific gravity, specific tenacity height, specific rigidity height, damping and amortization are good, the electromagnetic shielding ability strong, environmentally safe, and be easy to series of advantages such as recovery, be described as the green engineering material of tool development and application potentiality " 21 century ", more and more be subjected to the attention of industry member, becoming the third-largest metal engineering material after iron and steel and aluminium.Yet, magnesium alloy oxidizing fire very easily in fusion process, and easily be mixed with in the melt be mingled with, gas and harmful elements such as Fe, Si.Carry out refining and protection so magnesium alloy needs to add flux in smelting process, magnesium alloy flux directly affects the quality of magnesium alloy quality to the quality of liquid magnesium alloy refining and protection effect.There is the problem that refining effect is poor, the magnesium alloy metallurgical quality is not high in tradition magnesium alloy flux, and discharges the obnoxious flavour of higher concentration in use, influences the healthy of workman.
Summary of the invention
The object of the present invention is to provide a kind of used for magnesium alloy nanometer flux, be applicable to the melting of pure magnesium and magnesium alloy, by in flux, adding nano level magnesium oxide, zirconium tetrachloride and titanium dioxide, SODIUMNITRATE and Graphite Powder 99 etc., not only can carry out efficiency refining high, and can generate N melt
2And CO
2, melt is played a protective role, also diluted the concentration of obnoxious flavour.
The present invention is by the following technical solutions:

Second step, a certain amount of magnesium chloride, Repone K, bariumchloride are packed in the crucible, be warming up to 450～470 ℃, add Calcium Fluoride (Fluorspan) and sodium-chlor then, continue to be warming up to raw material and melt fully, be cast into bulk after stirring, behind broken, ball milling, become powder;
The 3rd step, add dry zirconium tetrachloride powder, powdered titanium dioxide, SODIUMNITRATE, Graphite Powder 99 and the sodium aluminum fluoride of crossing again, and adding the nano magnesia of handling through tensio-active agent, mechanically mixing on planetary ball mill is then through screening, pack after the assay was approved warehouse-in.
Add SODIUMNITRATE, Graphite Powder 99 and sodium aluminum fluoride in the used for magnesium alloy nanometer flux, in fusion process, can generate protective gas such as nitrogen and carbonic acid gas, can also protect melt effectively when purifying melt, avoid contacting and oxidizing fire with air.Also add zirconium tetrachloride and titanium dioxide in the flux, can remove harmful elements such as Si in the melt and Fe.In flux, add nano level magnesium oxide, utilize the particle size effect of nano material to absorb oxide inclusion in the melt, finally reach degasification purified effect.
Added nano level magnesium oxide in the used for magnesium alloy nanometer flux, principle according to nanoparticle size and surface atom number, nano material almost all is made up of the individual layer surface atom, the surface atom number increases, because Atomic coordinate is not enough and high surface energy, makes these surface atoms have high activity, and is extremely unstable, be easy to combine, thereby generate heavier macrobead oxide compound and sedimentation with oxide inclusion.Promptly compare, have the ability of better removing oxide inclusion with micron order or bigger size.
Beneficial effect of the present invention is:
(1) (main component is MgCl at traditional magnesium alloy flux
2, Repone K, Calcium Fluoride (Fluorspan), sodium-chlor, bariumchloride etc.) in add nano level magnesium oxide and be used for absorbing the oxide inclusion of melt, and in the flux preparation process, add tensio-active agent, prevent that nano particle from reuniting;
(2) add zirconium tetrachloride and titania powder, be used for removing melt Si and the Fe element bigger performance impact;
(3) add Powdered SODIUMNITRATE and Graphite Powder 99, generate protective gas such as nitrogen and carbonic acid gas, make bath surface protective layer show bubble, increased the contact area of melt and flux, make melt obtain better refining;
(4) use efficient nano flux of the present invention, use traditional magnesium alloy flux, can make the intensity of magnesium alloy improve 4～8%, elongation improves 5～10%.
