Description
Technical field
The present invention relates to a kind of high temperature process furnances, in particular to a kind of metal boiler tube heat expansion deforms controllable high-temperature heat treatment
Tube furnace.
Background technique
The second generation high-temperature superconducting coating band of deposition of metal organic route based on low cost during the preparation process, needs
It to be heat-treated in the high temperature furnace of certain length, since the condition required precision of heat treatment is higher, high temperature occurs in burner hearth
It is mobile to will drive air inlet/outlet, temperature measuring equipment etc. when thermal expansion deformation.And heat can be leaked if reserved mobile space seriously, in addition
It may cause the deformed damaged of some detection devices.
Due to intrinsic atom anharmonic vibration, most solid material shows " expanding with heat and contract with cold " phenomenon, leads to material
Size changes with variation of ambient temperature, has seriously affected equipment design accuracy and function；It is raw in the long band of second generation high-temperature superconductor
During production, long-term reciprocal temperature cycles also result in microstress concentration, shorten the service life of material and equipment.
Summary of the invention
Controllable high-temperature heat treatment tube furnace is deformed the object of the present invention is to provide a kind of metal boiler tube heat expansion, is mainly solved
The present long furnace of high temperature there is technical issues that heat expansion.
Thinking of the invention is the heat expansion problem on deformation for how providing a kind of structure and can control the long furnace of high temperature, in material
Field has been surprisingly found that " pyrocondensation cold expanding " phenomenon is presented in negative thermal expansion material, is the controlled material coefficient of expansion, improves scantling heat
Stability provides opportunity.By negative thermal expansion material and it is common it is positive thermal expansion (positive thermal expansion,
PTE) material carries out compound, and the thermal expansion of PTE material can be effectively suppressed or even realize zero thermal expansion.Therefore the present invention is quasi- selects rare earth
Tungstates negative thermal expansion material, Thermodynamically stable temperature range can be from room temperatures to 875 DEG C.In addition track bridge stress release is used for reference
Mode controls heat expansion problem on deformation by telescopic high-temperature bellow.
The technical solution of the present invention is as follows: a kind of metal boiler tube heat expansion deforms controllable high-temperature heat treatment tube furnace, tube furnace
It is mounted on the base, whole long boiler tube is separated into the short boiler tube of several sections, uses negative expansion boiler tube or high temperature wave between short boiler tube
Line pipe is arranged above tube furnace by flanged joint, air inlet pipe, is separately connected short boiler tube by pipeline, escape pipe is arranged in pipe
Below formula furnace, short boiler tube is separately connected by pipeline, temperature thermocouple is housed on each short boiler tube and is protruded into short boiler tube.Institute
Stating negative expansion boiler tube is rare-earth tungstate product.
Advantageous effects of the invention: by normally expand with heat and contract with cold material and negative thermal expansion material according to suitable ratio
Example is alternatively arranged, and form a whole the deformation that do not expand with heat and contract with cold with the lifting of temperature.Deformation is prevented to make equipment
Process conditions when at damage and influencing production.In addition track bridge stress release mode is used for reference, telescopic high temperature wave is passed through
Line control heating bulging deformation problem, part is fixed, and corrugated pipe connector discharges stress, integrally remains unchanged shape.
Detailed description of the invention
Fig. 1 is 1 structural schematic diagram of the embodiment of the present invention.
Fig. 2 is 2 structural schematic diagram of the embodiment of the present invention.
In figure: the short boiler tube of 1-, 2- negative expansion boiler tube, 3- air inlet pipe, 4- escape pipe, 5- temperature thermocouple, 6- flange, 7-
Pedestal, 8- high-temperature bellow.
Specific embodiment
Embodiment 1, referring to Fig.1, a kind of metal boiler tube heat expansion deform controllable high-temperature heat treatment tube furnace, tube furnace installation
On pedestal 7, whole long boiler tube is separated into the short boiler tube 1 of several sections, uses negative expansion boiler tube 2 to pass through flange 6 between short boiler tube 1
Connection, air inlet pipe 3 are arranged above tube furnace, are separately connected short boiler tube 1 by pipeline, and escape pipe 4 is arranged below tube furnace,
It is separately connected short boiler tube 1 by pipeline, temperature thermocouple 5 is housed on each short boiler tube 1 and is protruded into short boiler tube 1.According to just
The thermal expansion coefficient of normal burner hearth material and negative expansion furnace tube material (rare-earth tungstate) determines short boiler tube 1 and negative expansion boiler tube
The ratio of 2 length, to offset the normal swell increment of burner hearth with negative thermal expansion material reduction volume at high temperature.
Embodiment 2, referring to Fig. 2, a kind of metal boiler tube heat expansion deforms controllable high-temperature heat treatment tube furnace, tube furnace installation
On pedestal 7, whole long boiler tube is separated into the short boiler tube 1 of several sections, is connected with high-temperature bellow 8 by flange 6 between short boiler tube 1
It connects, air inlet pipe 3 is arranged above tube furnace, is separately connected short boiler tube 1 by pipeline, and escape pipe 4 is arranged below tube furnace, leads to
It crosses pipeline and is separately connected short boiler tube 1, temperature thermocouple 5 is housed on each short boiler tube 1 and protrudes into short boiler tube 1.According to normal
Burner hearth material thermal expansion coefficient determines the ratio of 8 length of short boiler tube 1 and high-temperature bellow.
