Description
Technical field
The present invention relates to vacuum high temperature furnace fields, more specifically to a kind of vacuum drying oven and its viewing window cleaner.
Background technique
Currently, viewing window cleaner is widely used in aerospace, automobile, food, tobacco, outdoor video monitoring device etc.
Industry, common cleaning device such as: windshield wiper, tobacco sorter viewing window cleaner, monitoring camera optical window, greatly
Part is worked in room temperature, normal pressure operating condition.In industry frequently with cleaning mode be broadly divided into contact and contactless clear
Clean two kinds.Contact cleaning mode is primarily referred to as cleaning brush and acts directly on form, carries out form by mechanical swing arm motion
Cleaning, by taking windshield wiper as an example, main purpose is exactly the letter for preventing rainwater and other pollutant effects driver sight and installing
Single burnisher, adhesive tape for wiper blade material are resistance to ozone and the strong rubber material of anti-uv-ray, have good water repellent and remove
Dirty effect, but this kind of rubber can not use in worst hot case.Non-contact cleaning mode mainly passes through gas or liquid is formed
Quick flow or liquid stream viewing surface is cleaned, this kind of device is complex, higher cost, with the view of tobacco sorter
For window cleaning device, wind-force is provided using blower to clean form, but can not be very high by the wind speed that blower provides, in addition
Wind speed is uneven, in electrostatic it is low with rate, EFFECTIVE RANGE is close etc., and reasons, form cleaning effect are undesirable.
In industrial circles such as aerospace, automobile, derived energy chemicals, many components are all long services at high temperature, are such as sent out
Motivation, boiler, refining equipment, cladding nuclear fuels pipe etc., they propose very high requirement to the high temperature resistant service performance of material,
Correct evaluation material, the heat-resisting material for reasonably using material, research new, become above-mentioned industrial development and material science research
One of vital task.By taking current nuclear power field research hotspot accident fault tolerant fuel (ATF) cladding tubes as an example, main target is
A kind of traditional zirconium alloy cladding pipe of novel fire resistant material enclosure pipe substitution is developed, in design basis accident and super design reference
Can be resisted under accident conditions high temperature, can prevent fission product release, fuel gas yield in permissible range in certain time,
Keep reactor core can cooling capacity high performance fuel system, reduce reactor occur major accident risk, alleviate major accident after
Fruit improves the extreme event ability that nuclear power station resists super design reference, improves the safety of reactor.
Advanced heat-resisting material refers to a generic material of the long-term work under high temperature and certain stress.Advanced resistance to height
Adiabator elevated temperature strength with higher, good anti-oxidant and hot corrosion resistance, good anti-oxidant and corrosion and heat resistant
Can, good fatigue behaviour, fracture toughness, plasticity etc..Currently, advanced heat-resisting material specifically includes that high temperature alloy, infusibility gold
Category, ceramics, intermetallic compound, metal-base composites, ceramic composite etc..High temperature furnace and in-situ measurement device combine
It is research advanced hightemperature mechanical property under high temperature complexity bad working environments, such as: stretching, creep, fatigue, fracture behavior machine
The important measurement method of reason, wherein the high temperature furnace infrared induction furnace that is rapidly heated by traditional resistance furnace till now, former
Level measuring arrangement is by traditional contact type measurement, such as: extensometer, and till now non-contact is measurement, such as: infrared survey,
High-speed camera etc., data acquisition rate and accuracy are continuously improved.But it finds in use, in-situ measurement device is to measurement
Form Penetration ration it is more demanding, with the decline of form Penetration ration in measurement process, measurement data will appear drift, influence to survey
Accuracy of measurement leads to not measure when serious, and this phenomenon is particularly evident in traditional high temperature vacuum resistance furnace, and main cause is such as
Under:
It (1) is more than 1000 DEG C of resistance furnace for using temperature, especially under high vacuum environment, calandria would generally be used
Molybdenum filament or graphite heating body, trace volatiles in use can be attached to viewing surface, reduce form Penetration ration；
(2) when being more than 1000 DEG C using temperature, structural member in furnace, such as piece fixture, heat screen, heat insulation foam, even
Certain oxysensible test specimens itself can also generate micro voloxidation object and be attached to viewing surface, reduce form Penetration ration；
(3) high temperature furnace is not it is difficult to ensure that furnace chamber has any pollution during cleaning, these pollutants are in the high temperature process
It can volatilize and be attached to viewing surface, reduce form Penetration ration；
Therefore, a kind of viewing window cleaner suitable for vacuum high temperature furnace is developed, it is first to promotion in-situ measurement device
It is of great significance into the further application in high-temperature material performance study.
High temperature high vacuum furnace viewing window cleaner is studied at present less, technical difficult points have as follows: first, it is only capable of
Contact cleaning mode is taken to clean form, because the high-speed flow cleaning form formed using gas can make in furnace
Vacuum degree and temperature generate fluctuation, influence measurement result, and volatile matter biggish for adhesive force not can guarantee and completely remove；
Second, cleaning device Fixture Design will guarantee the cleaning effect of form；Third, the material of cleaning device, especially cleaning brush material
The selection of matter, which will meet, to be used for a long time at high temperature；4th, cleaning device should guarantee the spirit of operation in use
Activity guarantees the vacuum degree in furnace chamber again.

Determine the moving range of cleaning head 72.
In an Application Example of vacuum drying oven, the molybdenum alloy testpieces 3 of diameter of phi 9.712mm is passed through into sample clamp
4 are clamped in high temperature resistance furnace, and the sealing element that sample clamp 4 is equipped with graphite material seals testpieces 3, in-situ measurement device
6 registrations are 9.71255, and data are shown accurately.
1100 DEG C are warming up to 10 DEG C/min heating rate, and after 1100 DEG C of stabilizations, 5MPa is introduced into pipe by pressure guiding pipe 5
Internal pressure, 6 data of in-situ measurement device be 9.71265, data display stablize.1100 DEG C of heat preservation 1000min or so, it is in situ to survey
Amount 6 data of device shows unstable, and registration fluctuates, and after showing that testpieces 3 is heated and volatilizing, cause dirt to 8 surface of form
Dye.
Further extend soaking time, in-situ measurement device 6 can not show measurement data, show that form 8 is completely dirty
Dye.Measurement window is cleaned by cleaning device 7, is cleaned 5~6 times repeatedly, 6 registration of in-situ measurement device reverts to 9.71365, shows
Number accurate stable.
Measurement window after wiping can guarantee that 6 registration of in-situ measurement device stablizes 1000min or so again, then measure
Registration can fluctuate again, until registration completely disappears.It repeats to wipe, it is ensured that the high penetration rate of measurement form 8 guarantees former
