Description
Technical field
What the present invention relates to is a kind of additive of metallic substance technical field, specifically, is a kind of aluminium alloy manganese additive that contains boride.
Background technology
Along with the whole world to the improving constantly of the energy and environmental requirement, secondary aluminium alloy occupies more and more consequence in China's aluminium industrial production, because the energy that needs of founding aluminium scrap will be far below the refining process of primary aluminum again.But the aluminium scrap wide material sources, sorting difficulty, dopant species are a lot of usually, and content is generally higher, and this is the main difficulty that secondary aluminum production faces, and the foreign matter content that reduces wherein is the main direction of studying at present in the scope that allows.Iron is wherein the most general impurity element, and to the performance hazards maximum of alloy.Because the solid solubility of iron in aluminium very little (0.05wt.%) therefore generally forms rich iron phase with elements such as Al, Si, these rich iron phases are the flaky hard crisp β-Al of pin especially
5FeSi has the different coefficients of expansion and Young's modulus with matrix, forms stress riser easily, thereby has influence on the mechanical property (plasticity, toughness, fatigue strength) of alloy.
At present, the method that is used for eliminating iron phase harm mainly is by adding alloying element (Mn, Cr etc.) form of the rich iron phase of needle-like of solidified structure to be changed into the less massive phase of harm, perhaps in melt, add alloying element and form after the primary Fe-rich phase by filtering or the mode of electromagnetic separation reduces the content of iron, industrial commonly used be to add the Mn element.Yet because the fusing point very high (1244 ℃) of manganese metal, normal aluminum alloy melt casting temperature has only 710-750 ℃, and therefore, how dystectic Mn being joined in the aluminium liquid cost-effectively is the problem of a key.Traditional method is at high temperature Mn and Al to be made master alloy, join after the fragmentation in the aluminium liquid, this method can consume a large amount of energy in the process of making master alloy and fragmentation, the master alloy Mn content that makes is not high, be generally 10wt.%, and Mn in Al very easily segregation cause the master alloy uneven components.The manganese additive of exploitation generally adopts simple substance manganese powder and a little auxiliary to make now, generally contains the manganese about 70wt.%.This kind manganese agent specific absorption depends on the size distribution and the size of manganese powder.The manganese powder diameter is thin more, and granularity is even more, and surperficial non-oxidation, and specific absorption just can improve.Therefore, producing manganese powder is the technological process of a complexity, highly energy-consuming, and specific absorption need prepare manganese powder with Milling and screening machine greater than 95% manganese agent under the argon shield condition.And add Al-Mn alloy or manganese agent and all can cause furnace temperature to descend, this all is disadvantageous to melting.
Find through literature search prior art, document " new and effective fast thawing manganese additive application prospect " (Liu Liang, Liu Guofan. Chinese manganese industry, 2004,22 (2): introduced the importance of development of new manganese additive to aluminium industry and Iron And Steel Industry 13-16), burn-off rate, specific absorption, cost, environmental protection etc. are the important directions of manganese agent development.The manganese powder of pure Mn (〉=99.5%) preparation has been adopted in the novel manganese agent of developing in this article, has investigated the influence of manganese powder particle diameter to casting yield, finds that the bigger manganese powder casting yield of particle diameter is big, melt slow and contradiction that manganese powder casting yield that particle diameter is smaller is little, fusing is fast.Therefore the control to the manganese powder particle diameter is a very difficult problem.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of simple and effective aluminium alloy manganese additive that contains boride is provided.The present invention can strongly promptly react in molten aluminium, restores Mn, the casting yield height, and reaction is thermopositive reaction, can not cause the reduction of furnace temperature.And than faster, the easier generation primary Fe-rich phase of common manganese agent, reduced the additional proportion of Mn simultaneously, reduced the residual of Mn, and this additive is easy to use, operating procedure is simple, with low cost.
The present invention is achieved by the following technical solutions, the chemical constitution of additive of the present invention is adjusted on the basis of molten aluminium insulating covering agent, and added boride and alleviate Manganous chloride tetrahydrate volatilization, its constituent mass percentage composition scope is: 10-25% sodium-chlor (NaCl), 10-25% Repone K (KCl), 1-10% sodium fluoroaluminate (Na
3AlF
6), 1-10% Sodium Tetraborate (Na
2B
4O
7), 30-75% Manganous chloride tetrahydrate (MnCl
2).Insulation can significantly improve Mn content in 5-30 minute after this additive only need add aluminium alloy melt.
Further, the preferable range of the quality percentage composition of said components of the present invention is: 15%-20% sodium-chlor, 15%-20% Repone K, 4%-8% sodium fluoroaluminate, 3%-7% Sodium Tetraborate, 40%-60% Manganous chloride tetrahydrate.
The additive that the present invention is above-mentioned, its production method is: earlier various starting material are put into stainless steel vessel respectively, then container are put into baking oven, be warmed up to 150 ℃-200 ℃, be incubated 2 hours-3 hours after, will expect that taking-up is stand-by.Accurately take by weighing each composition by the flux prescription, under 300 rev/mins speed, ball milling 1 hour 2 hours subsequently, packs it with ball mill.Additive was dried 1 hour 2 hours at 150 ℃ 200 ℃ before use.
During use, after aluminum or aluminum alloy melts in smelting furnace and is incubated for some time, by duster with manganese additive with gas (N
2Or Ar) spurt in the melt, and make manganese additive thorough mixing in whole molten bath, aluminium liquid adds the back at additive can carry out follow-up iron removal step in 5-30 minute, as filter, electromagnetic separation.
Manganese additive provided by the invention has advantages such as efficient, easy to operate.The Mn specific absorption of Al-Mn alloy addition has only 50-60%, the specific absorption of existing manganese agent seldom can reach more than 90%, be generally about 70%, and the manganese specific absorption of manganese additive of the present invention is generally about 80%, as optimizing technology according to actual condition, can reach more than 90%, and, compare traditional Al-Mn alloy and manganese metal agent, Mn is residual less, manufacture craft simple, can generate primary Fe-rich phase more efficiently.In the use of flux, Manganous chloride tetrahydrate can decompose rapidly, the manganese that generates has concentration fluctuations in melt, make forming core core easier grow up to critical size of iron phase in the higher zone of local manganese content, the forming core that this means iron phase is easier, so can form a large amount of primary Fe-rich phase rapidly in the melt.The present invention is fit to the melting requirement of aluminium alloy, has splendid viscosity and surface tension, and the separation property of flux and aluminium is good, has the function of melt covering protection concurrently.The chemical stability of flux is good, and the obnoxious flavour amount is few, meets industrial hygiene standard and waste gas emission standard.And flux adds conveniently, operating procedure is easy, with low cost.
