Abstract
The invention discloses a process for producing a rare earth aluminum alloy. The process comprises the steps of adding alloy elements in a melting pot, refining, and degassing with a hexachloroethane degassing agent; standing for 40min, transferring to a second pot, adding rare earth, then degassing and drossing. The method comprises the specific steps of 1) heating and cleaning a melting furnace device; 2) weighing 500kg of aluminum ingots, preheating and melting; 3) raising the temperature of the melting furnace after the aluminum ingots are melted, adding manganese chloride, then raising the temperature of the melting furnace to 800-850 DEG C, and stirring; 4) adding a No. 2 solvent and stirring; 5) degassing and then performing artificial drossing. The process disclosed by the invention has the beneficial effects that the aluminum alloy produced by the process has good corrosion resistance, excellent heat resistance and large strength and shock absorption performance, and is a high-quality alternative product of lightweight materials in the automobile manufacturing industry; in addition, the utilization rate of the rare earth in the production process is relatively high, so that the consumption of rare resources is further reduced.
Description
Technical field
The present invention relates to metal alloy novel material production technical field, especially a kind of production technique of rare earth aluminium alloy.
Background technology
Along with developing rapidly of global economy, automobile usage quantity increases year by year, a large amount of automobile makings becomes comparatively distinct issues to the consumption of the energy, the great attention of people to living environment on the other hand, environmental legislation is correspondingly strict gradually, make the energy-saving and emission-reduction of automobile receive all the more attention, lightweight has become the main direction of development of automobile.And aluminium alloy is as a kind of light-weight metal structured material, there is higher specific tenacity, specific rigidity, ratio of damping is low, damping property good, easily cut and be easy to the advantages such as recovery, becomes the weight-reducing material that automotive industry is selected.Rare earth element is very remarkable to the raising of corrosion resistance of aluminum alloy, and rare earth element alloy also can improve the high-temperature heat-resistance performance of alloy material mutually simultaneously.In traditional processing technology process, the mode of taking alloying, rare earth to carry out in one pot, because of added ingredients fusing point difference, refining, pouring temperature variation etc. cause impurity not easily separated, uneven components, rare earth element utilization ratio is low, and the rare-earth phase of separating out is inhomogeneous, segregation is many, larger to quality influence.Therefore, be badly in need of utilization ratio and alloying composition that a kind of new technology improves rare earth element, reduce production costs, seem extremely important of the quality that improves alloy billet.
Summary of the invention
The invention provides the production technique of a kind rare earth aluminium alloy.
The present invention is directed to the technical scheme that above-mentioned technological deficiency proposes is:
A production technique for rare earth aluminium alloy is carried out interpolation, the refining, degassed with hexachloroethane air release agent of alloying element in melting tank; After standing 40min, metaideophone enters in second pot and adds rare earth, then degassed, skim.
Concrete steps are:
1) heating of melting furnace device cleaning: heating crucible, adds the 2# flux of 2-3kg; When crucible heating arrives garnet, by crucible bottom and complete liquidation around, and blow clean with air gun;
2) take the aluminium ingot of 500kg and be preheating to 200-250 ℃, adding and in smelting furnace, melt 2.5-3.5h;
3) after aluminium ingot fusing, smelting furnace temperature raises as 760-790 ℃, adding 10.8kg temperature is the zinc ingot metal of 180 ℃ and the Manganous chloride tetrahydrate of 5.2kg, then the smelting furnace temperature that raises is to 800-850 ℃, installation mechanical stirring device stirs, stirring velocity is that 60r/min stirs 30min, and then adjustment stirring velocity is that 80r/min stirs 15min;
4) add 2# flux, then 40r/min stirs and carries out refining 3-5min, takes out whipping appts;
5) by 9kg temperature, be that the hexachloroethane air release agent of 80-120 ℃ covers at the bottom of pushing crucible and carries out degassed 8-10 minute with the bell jar that is preheating to 80-120 ℃, then manually skim.
Described 2# flux component and weight percentage thereof are: AlCl3: 45%, KCl: 30%, BaCl2: 10%, CaF2: 8%, NaCl: 7%; Described Manganous chloride tetrahydrate content is the 0.1-1.2% of add raw material.
The invention has the beneficial effects as follows: the aluminium alloy through above-mentioned explained hereafter has good corrosion resistance nature, superior resistance toheat has larger intensity and damping performance, is the high quality alternate product of automobile manufacture industry lighting material; In production process, the utilization ratio to rare earth is higher in addition, has further slowed down the consumption of scarce resource.
