Description
Technical field
The invention belongs to solar energy heat utilization technical field, particularly relate to a kind of high temperature resistant spring.
Background technology
In the case that fossil fuel reduces increasingly, solar energy has become the important component part that the mankind use the energy, and continuous
To development.The utilization of solar energy has photothermal deformation and opto-electronic conversion two ways, and solar electrical energy generation is a kind of emerging renewable energy
Source.The advantages such as solar energy has that stock number is big, has a very wide distribution, cleanliness without any pollution, technically reliable.Solar energy generation technology day
Benefit becomes China or even the emphasis of international renewable energy technologies development.China's solar energy resources enrich, national total area 2/3 with
On regional sunshine in year when grow up more than 2000 hours, year of China's solar energy resources, theoretical reserves were up to 1,700,000,000,000 tons of coals.
In the gatherer process of solar energy, solar energy heat collector is provided with the swivel joint for connecting line, connecting tube
Have the high-temperature medium of circulation inside road, swivel joint, swivel joint be internally provided with spring, therefore, the heat-resisting quantity of spring
There is serious impact in the service life of energy butt joint.At present, spring can only tolerate the high temperature of 300-400 DEG C, when the temperature of medium
When improving further, existing spring cannot meet use demand.
Content of the invention
The present invention is directed to above-mentioned technical problem, provide the high temperature resistant spring of a kind of Long-Time Service at 600 DEG C.
The technical solution adopted in the present invention is: a kind of high temperature resistant spring, it is characterised in that each component forms according to mass fraction
For: nickel 50-60 part, chromium 20-25 part, molybdenum 5-10 part, titanium 1-3 part, aluminium 1-3 part, tungsten 5-10 part.
Each component consists of according to more high quality number: 55 parts of nickel, chromium 25 parts, molybdenum 7.5 parts, titanium 2 parts, 1.5 parts of aluminium,
9 parts of tungsten.
The invention have the benefit that
1st, the spring resistance to elevated temperatures in the present invention is good, can have preferable resistance to lax at 600 DEG C of Long-Time Service at 600 DEG C
Performance, excellent spring；
2nd, component is simple, it is easy to processing, manufacture.
Brief description
The structural representation that Fig. 1-3 is applied in swivel joint for the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
In figure, 1-housing, 2-spring, the 3rd, the 4th, 5-seal, 6-connector.
First, embodiment 1-5
A kind of high temperature resistant spring, weighs each component according to the consumption in table 1, then according to following steps are processed:
(1) being processed into heat-resisting alloy by cooling formation technic, heat-resisting alloy is round steel wire between 1-10mm for the diameter；
(2) being placed in automatic spring winding machine, coiling is molded；
(3) it is then passed through stress relief annealing process, to eliminate the internal stress of wire cold-drawn processing and spring cold rolling forming；
(4) termination grinding, through special grinding wheel machine grinding, removes flash removed；
(5) again through stress relief annealing, halt process and inspection are then carried out；
(6) finally carry out the anti-corrosion treatment on surface, get product.
Each amounts of components detail list in table 1 embodiment 1-5
Fig. 1-3 is applied to the structural representation in 3 kinds of swivel joints, wherein, the housing of swivel joint for the spring in the present invention
1 selection 321 (0Cr19Ni10Ti) austenitic stainless steel, it is excellent that austenitic stainless steel has high temperature resistant, wear-resistant, resistance to oxidation etc.
Point, after processing, carries out solution treatment, high-temperature salt bath, increases case hardness and corrosion resistance；Seal the 3rd, the 4th, 5 be import
Graphite root timber material, be resistant to 1000 DEG C of high temperature, there is wearability high, service life the advantage such as length.
2nd, the concrete principle of the present invention is:
High temperature resistant spring is nickel-base heat resisting superalloy, and nickeliferous stainless steel is base material, with A3B type intermetallic compound
γ ＇-[Ni (AlTi)] is hardening constituent mutually.
Precipitation strength: by Ageing Treatment, separates out the second phase (γ ＇, γ ＂, carbide etc.), with by force from supersaturated solid solution
Alloy；γ ＇ phase is identical with matrix, is face-centred cubic structure, and lattice constant is close with matrix, and with crystal coherence, therefore
γ phase uniformly can separate out in fine particle shape in the base, hinders dislocation motion, and produces significant invigoration effect；γ phase is
A3B type intermetallic compound, A represents nickel, cobalt, and B represents aluminium, titanium, niobium, tantalum, vanadium, tungsten, and chromium, molybdenum, iron both can be
A can be again B；In nickel-base alloy, typical γ ＇ phase is Ni3 (Al, Ti)；The strengthening effect of γ phase can be obtained by following approach
Strengthen:
1. the quantity of γ ＇ phase is increased；
2. γ phase and matrix is made to have suitable mismatch, to obtain the strengthening effect of coherence distortion；
3. the element such as niobium, tantalum is added to increase the Apb Energies of γ phase, to improve the ability of its opposing dislocation cutting；
4. adding the elements such as cobalt, tungsten, molybdenum to improve the intensity of γ ＇ phase, γ ＂ phase is body-centered structure of the quartet, consisting of Ni3Nb.
Because γ ＂ phase is relatively big with the mismatch of matrix, coherence distortion largely can be caused, make alloy obtain very high yield strength；
But more than 700 DEG C, strengthening effect just substantially reduces；Cobalt base superalloy does not typically contain γ phase, and with carbide reinforced.
3rd, performance detection
According to JB/T6655-1993 high temperature resistant spring technical standard and GB/T10120-1996 metal stresses relaxation test method
Detecting the product in embodiment 1-5, concrete testing result is:
(1) according to high temperature resistant spring technical conditions standard (JB/T6655-1993), detection spring performance and limit deviation, refer to
Determine under the load of height, in embodiment 1-5 its length be 52mm deflection be 14mm, meet spring deflection negative in test
Under lotus deflection 20% to 80% between standard；Spring diameter is 85mm, and external diameter limit deviation 1.5mm, the rigidity limit is inclined
Difference is 10%, and limit deviation is in the range of meeting condition of work, and other detections all meet technical conditions and done and specify.
(2) stress relaxation test is to carry out at the temperature (i.e. 600 DEG C) of reality application, superalloy used by spring,
Its stress-strain diagram meets spring and uses condition.
Above 5 embodiments of the present invention are described in detail, but described content has been only presently preferred embodiments of the present invention, no
The practical range for limiting the present invention can be considered.All equalizations made according to the present patent application scope change and improvement etc., all should
Still belong within the patent covering scope of the present invention.
