Description
Technical field
The present invention relates to a kind of high-temperature mechanics experiment heater, relate in particular to a kind of high-temperature moire experiment heating furnace.
Background technology
It is the innovation in high-temperature mechanics field that the moire interference technology is used for the mechanical behavior under high temperature test, and high temperature moire experimental furnace is the indispensable supporting heater of high-temperature moire equipment.Domestic and international disclosed high temperature moire experimental furnace is very few at present, and mostly is used for scientific experiment, like " Experimental Mechanics " the 13rd volume the 3rd phase (1998.9) disclosed " high temperature moire experimental furnace and temperature-controlling system "; The Chinese patent of Tsing-Hua University's application; Publication number 101349549 " a kind of system for measuring high temperature moire interference deformation "; Mention all that high temperature moire experimental furnace is provided with and to test watch window, and have two layers of quartz glass to constitute, can make U, V field test collimated light through the through test specimen of window surface; Can take the moire image information through window simultaneously, body of heater has certain heat insulation function.But above-mentioned moire experimental furnace is sealed, the restriction of heat tracing and problem such as anti-oxidation, and maximum temperature can only reach 1000 ℃, can not be suitable for the requirement of higher temperature moire test.
Summary of the invention
The objective of the invention is to overcome the deficiency (background is said) of original high temperature moire experimental furnace, a kind of moire experimental furnace that can adapt to the higher temperature test request is provided.
Technical scheme of the present invention is following:
This high temperature moire experimental furnace comprises body of heater, charger of installing on the body of heater and heater, and the test watch window that body of heater is anterior, its special character is: the insulated water jacket is housed on the furnace body outer wall; Body of heater is provided with vacuum pumping opening, the protective gas air inlet, and thermocouple inserts mouth and wiring of input power source post, and these interfaces all are equipped with sealing device, and sealing device all is among the insulated water jacket.
The test watch window that is provided with on this high temperature moire experimental furnace fire door is spliced into the taper of cross semi arch by the insulation material in the fire door, is embedded with the two-layer quartz glass different with thin and thick is installed inside and outside the window respectively.
The fire door of said high temperature moire experimental furnace utilizes hinge to be connected with the front panel of body of heater, and the insulated water jacket also is housed on the outer wall of fire door, flows into recirculated water.
The test watch window that is provided with on the said high temperature moire experimental furnace fire door, the thick quartz glass that is installed in its outer surface can be square, and its four jiaos of corresponding placements with the cross window are to practice thrift the quartz glass area.
The heater of this high temperature moire experimental furnace can be employed in vertically settles Elema in the burner hearth, to improve heating-up temperature, be connected with it through high temperature resistant wire.
The present invention and comparing with prior art have better sealing property, and vacuum-pumping injects protective gas, prevents the metal material oxidation; Be employed on the outer walls such as furnace body frame, bonnet, fire door the insulated water jacket is installed, guarantee that each seal avoids temperatures involved; The employing Elema heats, and has improved the temperature of heating source; Test window adopts cross semi arch pyramidal structure, has reduced heat radiation and amass, and four jiaos of square thick quartz glass and cross circular arc tapered window corresponding matching not only help the interference light input, and dwindled the quartz glass area, the saving cost simultaneously.Owing to taked above-mentioned aggregate measures; Moire experimental furnace of the present invention, the highest probe temperature can reach 1300 ℃, in the practice; Utilized high temperature moire experimental furnace of the present invention to accomplish the mechanical behavior under high temperature test of more than 70 kind of high temperature alloy and metal-base composites, the highest probe temperature is 1200 ℃.This experimental furnace also can with the supporting use of electronics tensile and compression testing machine, creep testing machine and fatigue tester, carry out tests such as high temperature tension and compression, high-temerature creep, fatigue at high temperature.
