Description
Technical field
The utility model is related to force snesor, more particularly, to a kind of high-temperature resistant air cooling shaft type force snesor.
Background technology
With ripe day by day, the continuous development of metallurgical technology, continuous casting steel machine becomes highly important in Steel Production Flow Chart
Link.Continuous casting installation for casting includes：Big packet, tundish, crystallizer, two cold-zones etc..Wherein ladle is splendid attire and the equipment for transporting molten steel；
All using bale panoramic tables, big or middle packet weighs for current CC at home ＆ abroad development, because entire continuous casting production process measures molten steel
Directly affect being smoothed out for continuous casting.Big packet, which weighs, can determine pouring molten steel residual volume in ladle, be conducive to improve steel
Material recovery rate can control tundish liquid level, molten steel in ladle highly can be monitored, find out the critical of removable field trash
Face, and middle packet Liquid level provides reliable parameter regulation for casting process casting speed, be conducive to continuous casting normally into
Row, guarantee is non-leakage, is uninterruptedly produced.Therefore for weigh quality and the reliability of ladle in continuous casting process for steel
It is played a very important role in terms of quality and raising work efficiency.Country's steel ladle balance is all by being divided into ladle support plinth at present
Meter installation force snesor, generally bridge type magnetic sensor, since sensor mounting location and ladle position are very close, and ladle
It is not capped, so the temperature of spot sensor installation site is very high, up to 200 DEG C~250 DEG C.The Shen Ke great of import at present
Packet scale sensor highest also only reaches 150 DEG C, and onsite application can only be isolated thermal insulation protection by multilayer and be used, but actually make
Unsatisfactory with effect, service life more than half or even some thermal insulation protection use not in place short compared with nominal sensor is not
It was just damaged by one month.
Invention content
The purpose of this utility model, which is to provide, to be passed in a kind of high-temperature resistant air cooling shaft type power of normal use under worst hot case
Sensor.
To achieve the above object, the utility model adopts the following technical solution：
A kind of high-temperature resistant air cooling shaft type force snesor, including sensor body and strain gauge patch, feature is, sensing
Device ontology is circle axis structure, and circular shaft formula pressure-bearing surface, the external carrying roller of the pressure-bearing surface, sensor sheet are equipped in the middle part of sensor body
Body axial line is equipped with axial blind hole, which is equipped at intervals with edge as cold wind import on sensor body pressure-bearing surface surface
Axial heat dissipation straight slot, each straight slot middle part of radiating is equipped with the through-hole with the cold wind import radial communication, in sensor body
Non-pressure bearing face surface, it is symmetrical to be arranged at intervals with radial direction thermal vias on the basis of pressure-bearing surface radial center cross section, it is each to dissipate
Heat through-hole is connected with the cold wind import, and for each thermal vias as strain gauge patch heat emission hole, strain gauge patch is affixed on adjacent 2
Non-pressure bearing face surface between radial direction thermal vias.
Further：
The diameter that the sensor body pressure-bearing surface is surrounded is more than the diameter that non-pressure bearing face is surrounded.
The quantity of the heat dissipation straight slot is 8, in setting uniformly at intervals.
The quantity of the thermal vias is 8, and left and right is all provided with 4, and every 2 are a pair, and perpendicular to cold wind import, adjacent
Two pairs of thermal vias is arranged at intervals, and in non-intersecting cross setting.
Compared with the prior art, the beneficial effects of the utility model are as follows：
Air-cooled shaft type force snesor uses the structure of shaft type, and the installation of more traditional bridge type magnetic sensor is more reliable and stable,
Blind hole is axially beaten as air-cooled main air inlet in one end center of shaft type sensor.Then in sensor cylindrical shape pressure-bearing surface
On open four pressure-bearing radiating grooves, groove center gets through Kong Yuzhu air intake passages and is connected.Simultaneously above and below the non-pressure position of sensor
It is each to make a call to four through-holes and be connected with main air intake passage as patch radiating groove.Strain transducer meter patch location is just in 2 patches
The centre of radiating groove.The high temperature of sensor patch position can be reduced in this way, inhibit strain gauge aging.In use, by air-cooled axis
Formula force snesor is rack-mount, after normal (low) warm air is inputted cold wind import by air compressor machine, is carried out by radiating groove
Heat dissipation in time.In the case where normal temperature air is used to carry out air-cooled effect, this sensor can use the high temperature work within 350 DEG C
Condition, if being cooled down using cryogenic gas, the sensor of this design can be with high temperature resistant, 500~600 DEG C.It can be in the utility model
Reliability and service life can be remarkably improved in normal use under worst hot case.Through experiment, excellent.
