Description
The present invention relates to the preparation method of the aluminium base master alloy of a kind of titaniferous, carbon, belong to the metallic substance technical field.
The aluminium base master alloy of titaniferous, carbon has quite widely to be used.Early stage research is carried out it as conventional aluminium and aluminum grain refiner.
Realize micritization and and then reach highly malleablized, be important and general research topic in aluminium and aluminium alloy and other metallic substance.Research to grain refining at present mainly comprises two approach, i.e. physical method and chemical process.Specific form is just like rapid solidification, stirring and interpolation nucleating agent (grain-refining agent) and powder metallurgy etc., wherein the most effective practicality and economic method is to add nucleating agent.
For commercial-purity aluminium and aluminium alloy, the fining agent that generally uses is the master alloy of series such as AlTi, AlTiB at present, and wherein Al5Ti1B is one of best fining agent of generally acknowledging in the world at present.But, still have some inborn problems that are difficult to overcome.At first, AlTiB fining agent TiB in use
2Particle is assembled easily, is precipitated, and influences its decline performance greatly, damages the surface quality of stocking especially greatly and damages roll; In addition, the AlTiB fining agent can lose thinning effect to aluminium and the aluminium alloy that contains elements such as Zr, Cr.The AlTiC that the eighties develops is that fining agent is that the problems referred to above have found a new solution route.Yet owing to the reasons such as wettability difference of aluminium liquid and graphite, carbon is introduced in the aluminum titanium alloy very difficult.At present, the typical preparation technology of AlTiC master alloy fining agent is the patent that Banerji and Reif deliver in the mid-80, is promptly adding certain particle size (mean particle size is 20 microns) under the high temperature more than 1250 ℃ and also stir to reach more than 30 minutes fast at 0.5-1 hour carbon dust of 700-900 ℃ of oven dry in advance and make in the Al-Ti alloy melt.Its complex manufacturing, raw material and technology cost are very high, and the stability of producing is not high.Above-mentioned factor has greatly hindered the development of AlTiC series fining agent.At present, the production of AlTiC fining agent only only limits to laboratory scale in the world, is small-scale industrial production at the most, also seldom uses on a large scale in the aluminium industrial production.
In addition, at the end of the eighties, along with XD
TMEtc. the appearance of spontaneous synthesis technique, Al-TiC is the interest that the research of in-situ composite begins to cause people, causes the extensive attention of international material circle gradually after entering the nineties and becomes one of focus of material Application Areas.At present, the XD that develops by the U.S. Martin Mametta company end of the eighties
TMTechnology is still the main technology of preparing that Al-TiC is an in-situ composite.Its principle is that Ti, C powder and matrix Al or the Al powdered alloy that will generate TiC mix, and being higher than the matrix fusing point, being lower than under the single TiC synthesis temperature condition, makes between Ti, the C to react, thereby form TiC strengthening phase particle in aluminum substrate.In this preparation method, wild phase element powders and matrix powder prefabricated and mix make the raw materials cost of this method very high, complex process, control difficulty and have suitable danger, be difficult to carry out large-scale industrial production.In recent years, for avoiding XD
TMThe above-mentioned shortcoming of method, it is in-situ composite that domestic and international many investigators adopt conventional founding+remelting chilling technology to prepare Al-TiC.In its conventional founding, be raw material with aluminium ingot, titanium ingot or aluminum-titanium alloy ingot and Graphite Powder 99, melting method reference A.Banerji and W.Reif prepare the method for Al-Ti-C grain-refining agent.Therefore, this Al-TiC is that preparation method and the Al-Ti-C of in-situ composite is that the preparation method of fining agent is the same, has very big defective, is difficult to apply.
The objective of the invention is to propose the preparation method of the aluminium base master alloy of a kind of titaniferous, carbon, defective at existing the whole bag of tricks, a kind of preparation method who contains Ti, the aluminium base master alloy of C simple again brand-new the time has been proposed, adopting commercial-purity aluminium and fluotitanate (potassium fluotitanate or titanium sodium fluoride) is raw material, replace in original method the metallic aluminium, metal titanium or the Al-Ti alloy raw material that generally adopt, thereby dissolving and reaction take place in carbon dust can make full use of fluotitanate when decomposing liberated heat and active titanium atom; Add constituent element X activation melt simultaneously, improve the wettability in molten aluminium and the carbon granules, significantly promote the absorption of carbon.
A kind of titaniferous that the present invention proposes, the aluminium base master alloy of carbon, it consists of:
Component content (wt%)
Aluminium (Al) 80.48-99.98
Titanium (Ti) 0.001-10.00
Carbon (C) 0.001-4.00
Topped dose of 0.05-5
Activator (X) 0.00-4.50
The preparation method of the aforesaid master alloy that the present invention proposes comprises following each step:
1. prepare raw material for standby by formula rate;
2. the fusing commercial-purity aluminium adds activator in proportion to 750-850 ℃ in resistance furnace or induction furnace:
3. after 1-3 minute, add fluotitanate and Graphite Powder 99 in proportion, and add insulating covering agent, keep reaction 10-30 minute;
4. slagging-off is cast into ingot, promptly obtains the product master alloy.
Above-mentioned activator comprises one or more in rare earth element (lanthanum (La), cerium (Ce) etc.) and the alkaline earth element (magnesium (Mg), calcium (Ca), strontium (Sr) etc.).The main effect of its () activates molten aluminium on the one hand, promotes the absorption of carbon; Also reduced simultaneously the TiC agglomeration of particles that generates; Also strengthen the interface compatibility of TiC particle and aluminum substrate in the master alloy on the other hand.
The method that the present invention prepares above-mentioned fining agent is: the component proportions by design requirements in advance is ready to commercial-purity aluminium, fluotitanate (potassium fluotitanate or titanium sodium fluoride), Graphite Powder 99 (granularity is below 50 microns), activator (rare earth element or alkaline earth element or their mixture) and mixing salt insulating covering agent raw material for standby such as (50wt% Repone K+50wt% sodium-chlor).
The fusing commercial-purity aluminium adds promoting agent (X) earlier to 750-850 ℃ in induction furnace or resistance furnace, adds fluotitanate and Graphite Powder 99 simultaneously after about 1-2 minute, and adds the mixing salt insulating covering agent.For resistance furnace, can utilize the carrying out of mechanical agitation accelerated reaction; For electromagnetic induction furnace, utilize himself function composite by electromagnetic stirring to stir and get final product.After about 10-30 minute, slagging-off is cast into ingot, is the product master alloy.The recovery rate of titanium and carbon is all more than 90% among the present invention.
