Description
Technical field
The present invention relates to a kind of beryllium copper and amorphous and/or nanocrystalline strip production unit copper sheathing and preparation method.
Background technology
Beryllium copper is the good a kind of alloy of mechanics, physics and chemical over-all properties, it is a kind of malleable and castable alloy, the copper base alloy that belongs to the timeliness precipitation strength, after handling, quench aging has high intensity, hardness, elastic limit, and good stability, have corrosion-resistant, wear-resisting, antifatigue, low temperature resistant, nonmagnetic, electrical and thermal conductivity is good, can not produce series of advantages such as spark during impact, is described as " king of coloured resilient material ".In recent years, the beryllium copper range of application is progressively enlarging, be widely used in multiple fields such as electronic apparatus, communication Instrument, aerospace, petrochemical complex, metallurgical mine, vehicle appliance, machinofacture, become indispensable essential industry material in the development of the national economy.
Because the good thermal conductivity of beryllium copper, in amorphous and/or the production of nanocrystalline strip continuous casting, used crystallization roller often adopts the beryllium copper copper sheathing.Yet, present beryllium copper copper sheathing, still not fully up to expectations aspect thermal conductivity and intensity, hardness.
Summary of the invention
The object of the present invention is to provide a kind of beryllium copper, is the beryllium copper material that a kind of intensity and thermal conductivity can be fit to amorphous and/or nanocrystalline strip production unit usefulness copper sheathing.
The present invention takes following technical scheme to realize:
A kind of beryllium copper, described beryllium copper are to contain element Be and Co in copper, and the quality percentage composition of described element is respectively, Be:0.25-2.1%, Co:0.1-2.0%.
Also comprise element Zr and Si in the described beryllium copper, the quality percentage composition branch of described element is Zr:0.01-0.65%, Si:0.01-0.06% in addition.
Ag, Cr, Al, Mg, Fe, P and the Ni trace that can also comprise trace in the described beryllium copper further, and impurity, the impurity summation is less than 0.5%.
The present invention also provides a kind of manufacturing amorphous and/or nanocrystalline strip production unit copper sheathing, is the copper sheathing that utilizes above-mentioned beryllium copper to make.
The present invention also provides a kind of preparation method of above-mentioned copper sheathing, comprises following process:
(1) smelts: prepare starting material and accurately weighing by the castings production requirement, will consider the burn out rate of element during batching.Electrolytic copper blast after 500-550 ℃ of preheating is removed dirt and moisture, and beryllium generally adds with beryllium copper master alloy form.The maximum lumpiness of metal charge should not surpass 1/3 of crucible diameter, and length should not surpass 4/5 of the crucible degree of depth.Should strictly control smelting temperature in the fusion process, because temperature is higher, alloy is bigger to Gas Solubility, so smelting temperature should be controlled at 1250-1350 ℃.The air-breathing oxidation of berylliumbronze is serious, and will taking measures in the non-vacuum melting process, it is air-breathing to prevent.Better through verification experimental verification with cupric oxide powder, and use borax, glass cullet to cover and to lead to the technological effect of argon gas degasification best.
(2) casting: will smelt good beryllium copper and water ingot or strand, teeming temperature should be controlled at 1000-1150 ℃.
(3) forge hot: strand is carried out forge hot 600-910 ℃ of temperature range, and forge hot presses down rate 〉=20%.
(4) thermal treatment: berylliumbronze is the heat treatment reinforcement alloy, and foundry goods will be heat-treated and could be obtained optimum performance, and therefore, heat treatment process parameter is very crucial for the performance of berylliumbronze.General thermal treatment is carried out in two steps, and the first step is that foundry goods is carried out solution treatment (quenching), and second step was age hardening.The selection of quenching temperature should be considered the abundant dissolving of beryllium, so that obtain oversaturated αGu Rongti.Make timeliness subsequently have enough strengthening phases to separate out, thereby reach the ideal mechanical property.But too high quenching temperature can make α phase grain growth, even the local scorification of crystal boundary and produce overheated and burn-off phenomenon.The Heating temperature of solution treatment should be controlled at 760-850 ℃, and solution treatment furnace temperature uniformity coefficient should be strict controlled in ± and 5 ℃.Treatment time varies in size according to foundry goods, and the time is 4-11 hour.At 300-500 ℃, be incubated 5-30 hour and carry out ageing treatment afterwards.
Aforementioned trace, be meant element in alloy content ten thousand/below, 1,000,000/above component.
Beryllium copper of the present invention and copper sheathing, its Rockwell hardness HRC is: 18-42, softening temperature＞600 ℃, thermal conductivity is: 70-200W/m.k, tensile strength is: 450-1100Mpa.
With amorphous and/or the nanocrystalline strip production unit copper sheathing that described beryllium copper is made, the interactional advantage of performance alloying element, the magnetic property that can effectively improve amorphous, nanocrystalline strip (improves Bs, Br, reduces coercive force and loss P simultaneously
1.3/50Hz≤ 0.2w/kg) and surface quality, reducing thickness of strip simultaneously to 30um, and can effectively improve strip surface planeness, density and stacking factor, this strip product is applied to the power electronics industry and has good energy-saving effect, obvious social benefit.
The invention has the beneficial effects as follows:
A kind of beryllium copper of the present invention, on the beryllium copper basis, add elements such as Co, Si, Zr, and pour into ingot casting or strand by the alloy after will smelting, strand is carried out processing steps such as forge hot, insulation and ageing treatment, prepare the beryllium copper material that meets amorphous, nanocrystalline strip production unit usefulness copper sheathing of high strength and high thermal conductivity.The beryllium copper copper sheathing is applied to the visual appearance and the actual performance that can promote amorphous, nanocrystalline strip in the band production link effectively, the performance of iron core product also can be improved accordingly, be applied to field of power electronics, can make device miniaturization, loss reduces, not only economical with materials but also save energy, obvious social benefit.
