The utility model solves the problems of complexity, thickness, low temperature measuring speed, short service life, inconvenience replacement, higher cost, etc. existing in the prior art. The utility model has the advantages of simple integral technical structure, reasonable structure, convenient fabrication, low fabricating cost, high temperature measuring precision, etc.
Description
Technical field
The utility model belongs to molten metal liquid temperature to be measured fast, particularly makes the miniature blackbody cavity temperature probe of the quick actinometry molten metal liquid temperature of a kind of noncontact.
Background technology
The world today extensively adopts the expendable thermopair to the temperature survey of molten metal bath, makes disposable use temperature probe.Along with riseing of noble-metal thermocouple silk price year after year, need a kind of temperature measuring equipment that replaces quick consumption-type thermal couple of development.
Recently the technician utilizes the relevant performance of infrared optics technology and black matrix, grey body in the new method of making great efforts research and development measurement molten metal liquid temperature, develops multiple Radiation Temperature Measurement Instrument.But radiation temperature measurement generally is a contactless temperature-measuring, measurement be the surface temperature of motlten metal table, can not record inner real temperature, and be subjected to the factor affecting of the black matrix emissivity of testee and measurement environment big, anti-interference is poor.The present domestic report that has can adopt graphite or metallic ceramics to insert molten metal bath as blackbody cavity and carry out continuous temperature measurement, but blackbody cavity complex structure, thick and heavy, thermometric speed is slow, the life-span short, change inconvenience, and cost is higher; The consumption-type optical fiber radiation thermometer that also has the exploitation of Japanese NKK company is that the termination of optical fiber is invaded in the molten metal bath, utilize cylinder cavity that the heart yearn of profile of optic fibre and covering form as miniature blackbody cavity, consume optical fiber and measure the temperature of molten metal bath fast, but what adopt is FIMT (fiber in metallic tube) optical fiber, the more expensive present home market of price is rare, the numerous and jumbled costliness of entire measuring device.Though these designs have well solved the obstacle of optical radiation measurement molten metal liquid temperature, are difficult to realize.
Summary of the invention
The purpose of this utility model is on the basis of the thermocouple probe of the quick measurement of existing manufacturing molten metal liquid temperature, in conjunction with the optical radiation thermometry, development is used for the miniature blackbody cavity temperature probe of actinometry molten metal liquid temperature, substitute the quick temperature measurement probe that thermocouple wire is made, be convenient to batch process and use, reduce cost.
One-piece construction of the present utility model is:
At least one end be the thermostable heat-conductive pipe separated of cecum or middle part or light-transmission tube 3 with base 5 on the through hole 6 fixing assemblings of offering.
Specific structural features of the present utility model also has:
Front end protuberate basic unit 5 outside surfaces of thermostable heat-conductive pipe or light-transmission tube 3.
The base 5 outside surface surface encapsulation that are positioned at thermostable heat-conductive pipe or the light-transmission tube 3 front ends outside have shielding cap 2.
The fusing point that shielding cap 2 selects for use thin-walled material to make and make material is lower than the fusing point of testee.
Secure fit is adopted on the bottom of shielding cap 2 and base 5 surfaces.
The bottom of shielding cap 2 is adopted to be adhesively fixed with base 5 surfaces and is cooperated.
Thermostable heat-conductive pipe or light-transmission tube 3 are selected high-temperature resistant glass tube for use.
The front end of thermostable heat-conductive pipe or light-transmission tube 3 is a cecum.
Cavity owing to thermostable heat-conductive pipe in the miniature blackbody cavity temperature probe or light-transmission tube 3 during use is very little, the chamber wall is also very thin, opening is aimed at the small diaphragm that passes photosystem, so can in molten metal bath, form an isothermal wall cavity, has good black matrix condition, can regard the emissivity of thermometric object as 1, realize high-precision temperature survey.
The obtained technical progress of the utility model is:
1, overall technology of the present utility model is simple and reasonable for structure, and is easy to make.
2, select inexpensive thin-walled miniature quartz (or other exotic material) the glass tube valuables such as thermocouple wire, U type quartz ampoule, compensating wire that replace for use, the cost of manufacture of temperature probe is reduced greatly, be convenient to use as consumptive material.
3, measuring accuracy height.
