Description

Aluminium alloy additive
[technical field]
The present invention relates to aluminium alloy smelting technical field, particularly relate to a kind of aluminium alloy additive.
[background technology]
Current China has nearly 85% to be apply with the form of aluminium alloy in the aluminium total amount of consumption, need during smelting aluminium alloy to add various alloying element, to make the aluminium alloy of heterogeneity and model, meet different performance requirement, conventional unit have silicon, iron, copper, manganese, titanium, magnesium, chromium, tin, boron, rare earth etc.For fusing point, low and solubleness is very high in aluminium alloying element is as magnesium, zinc, mainly adds in pure metal mode.The metal that the fusing points such as silicon, iron, manganese are higher then adds with master alloy form, as aluminium silicon master alloy (silicon content 19%-21%), ferro-aluminum master alloy (iron-holder 19%-22%), aluminium manganese master alloy (manganese content 9%-11%), this method have easy and simple to handle, add-on accurately, alloying constituent is convenient to the advantages such as control, but energy consumption when master alloy is produced is very high, in aluminium alloy process for preparation, particularly add the loss of alloying element, waste greatly.
In correlation technique, occurred carrying out with metal additive the new form that adds, this metal additive comprises chalybeate, manganese agent, silicea etc.Metal additive fully mixes compacting with the pure metal powder of 75% and the fusing assistant (being made up of villiaumite, nitrate, villaumite and carbonate) of 25% to form, though it solves some shortcomings of adding in contained aluminium-base intermediate alloy mode, still there is following problem in current this additive: solvent temperature is high, specific absorption is unstable; The density of metal additive is general all large than aluminium, and when addition is very large, additive sinks to furnace bottom, forms bulk, has a strong impact on specific absorption.
Therefore, be necessary to provide a kind of new aluminium alloy additive to overcome above-mentioned technical problem in fact.
[summary of the invention]
The technical issues that need to address of the present invention are to provide that a kind of specific absorption is higher, the aluminium alloy additive of Vapor recovery unit.
A kind of aluminium alloy additive of the present invention, by weight percentage, comprises following component:
Wherein, described metal-powder purity is more than or equal to 99.5%, and granularity is 70-120 order.
Preferably, described metal-powder is iron powder, copper powder, manganese powder, titanium valve or chromium powder.
Compared with correlation technique, beneficial effect of the present invention is, (710-720 DEG C) can realize high specific absorption at a lower temperature, and dissolution rate is fast.The potassium cryolite added can not only promote that alloying element absorbs, and can also play slagging-off effect, and the interpolation of potassium silicofluoride can not only bulking additive block, discharges protective gas simultaneously, is conducive to the degasification of aluminium liquid, further increases the purity of aluminium liquid.Thus, described aluminium alloy additive possesses high specific absorption and stability, also possesses the cleaning molten ability of degasification slagging-off simultaneously.
[embodiment]
Below in conjunction with embodiment, the invention will be further described.
Described aluminium alloy additive by weight percentage, comprises following component: metal-powder 70-90%; Potassium cryolite 5-20%; Potassium silicofluoride 0-5%; Higher fatty acid salt 0-5%, wherein, described metal-powder purity is more than or equal to 99.5%, and granularity is 70-120 order.
Metal-powder granularity is comparatively thin, and purity is higher, can with aluminium liquid generation thermite reaction, promote that it absorbs.Potassium cryolite fusing point is low, under interpolation temperature (710-760 DEG C), can become liquid state rapidly, dissolution of metals powder surface and alumite, penetration enhancement.Potassium silicofluoride is as swelling agent and initiator; at interpolation temperature, undergoes rapid expansion, is conducive to aluminium liquid and enters into additive block inside; further promotion metal-powder and aluminium liquid generation thermite reaction; improve the casting yield of alloying element, meanwhile, himself decomposes; release protective gas; additive is fluctuated, slows down settling velocity, the dissolution rate of alloying element improves more than 1 times.Higher fatty acid salt its cohesive action main, is convenient to briquetting.The principal feature of this additive is as follows: 1, specific absorption is stable and high; 2, the potassium cryolite in additive possesses slagging-off ability, and potassium silicofluoride decompose themselves release guard gas possesses deaeration capability, and therefore this additive also helps the purification of melt.
Thus this aluminium alloy additive (710-720 DEG C) can realize high specific absorption at a lower temperature, and dissolution rate is fast.The potassium cryolite added can not only promote that alloying element absorbs, and can also play slagging-off effect, and the interpolation of potassium silicofluoride can not only bulking additive block, discharges protective gas simultaneously, is conducive to the degasification of aluminium liquid, further increases the purity of aluminium liquid.Thus, described aluminium alloy additive possesses high specific absorption and stability, also possesses the cleaning molten ability of degasification slagging-off simultaneously.
The making method of aluminium alloy additive, is equipped with raw material according to the above ratio, by 70-120 object metal-powder and appropriate potassium cryolite, potassium silicofluoride, mixes, then adds in said mixture by the higher fatty acid salt of having dried, all mix.Compacting in specific mould, is prepared into the powder agglomates of about density 3.5g/cm3, every block about 500g, then vacuum sealed package.
In present embodiment, described metal-powder is the metal-powder that the purity such as iron powder, copper powder, manganese powder, titanium valve or chromium powder are higher.
Be described further below in conjunction with specific embodiment.
Embodiment one:
A kind of aluminium alloy additive, comprises following component: iron powder 70kg; Potassium cryolite 20kg; Potassium silicofluoride 5kg; Higher fatty acid salt 5kg, wherein, described iron powder purity is 99.5%, and granularity is 80 orders.
