Description
Technical field
The utility model relates to infrared optics thermometry field, refers more particularly to the infrared continuous temperature measurement device to high-temperature molten steel.
Background technology
In recent years, in steel industry, used tundish molten steel infrared optics continuous temperature measurement technology, adopted this technology to show continuously and write down molten steel temperature in tundish automatically, be convenient to continuous casting operation and in time adjust and control.The infrared optics temp measuring system shows that by temperature tube, infrared signal collecting transmitter and signal Processing and temperature several parts constitute.Wherein temperature tube is daily main wearing detail, accounts for more than 80% of infrared optics temp measuring system use cost.
Temperature tube is a kind of end sealing, and the fire resistive material body of an end opening is generally by Al
2O
3, C, Si constitute.Chinese patent ZL200620165325.6, Chinese patent 200720113118.0, Chinese patent 200920143429.0 and 200920142942.8 disclose temperature tube structure separately (seeing that Fig. 1 shows) respectively.In technique scheme, all used mono-layer tube, reduced the time of temperature tube perception high-temperature molten steel temperature, simultaneously, adopt different purging measures separately, optical channel to temperature tube purges purification, and flue gas that temperature tube material self produces when having alleviated high temperature or volatile matter be to the pollution of infrared optics passage, thereby has improved the response speed and the accuracy of infrared measurement of temperature.
The thermometric response speed of temperature tube depends primarily on the thickness of blind end, the coefficient of heat conductivity and the blackness of material, especially Di Bu thickness, coefficient of heat conductivity and blackness.In above-mentioned each technical scheme, have several common problems: the bottom of (1) temperature tube sealing is hemispherical thin-wall construction, processing difficulties.In the high speed rotating process vibrations or swing can take place, easily form manufacturing deficiency, be difficult to guarantee temperature tube end sphere walled thickness unanimity, cause the temperature tube performance inconsistency.Wall thickness is inconsistent will to cause the temperature tube unstable properties produced in batches: the big thermometric response speed of wall thickness is slow, and wall thickness is just very low too thin serviceable life.(2) in above-mentioned patented technology, making temperature tube body and bottom all is with a kind of aluminium carbonaceous material, does not adopt the bigger material of coefficient of heat conductivity to carry out compound manufacturing in bottom temperature perception zone, therefore, has limited the thermometric response speed and has improved.(3) because temperature tube generally is the aluminium carbonaceous, easily oxidation, though therefore the surface has sprayed one deck antioxidizing paint, when carrying out high-temperature baking with tundish before use, to a certain degree oxidation still can take place in top layer, temperature tube bottom (blind end).The oxidation of temperature tube bottom not only reduces temperature conductivity, reduces the thermometric response speed, and can influence serviceable life.
The utility model content
For solving the prior art existing problems, the utility model provides a kind of continuous measurement of molten steel temperature with inserted compound infrared measurement of temperature pipe, utilize this temperature tube can improve thermometric response speed, serviceable life and stability, reduce temperature tube manufacturing cost and use cost simultaneously.
For achieving the above object, the continuous measurement of molten steel temperature that the utility model provides comprises connecting piece, scavenging duct, temperature tube body with inserted compound infrared measurement of temperature pipe, it is characterized in that, described temperature tube body underpart opening; The groove of conducting strip is inlayed in the inner chamber setting of temperature tube body bottom, and conducting strip is mounted in the described groove, and cements with the high temperature clay, forms the blind end and the temperature Perception Area of described temperature tube; Described temperature tube body bottom outside surface suit protective cover.
Further improvement of the utility model is, the described groove of inlaying conducting strip is an annular groove, and described conducting strip is a truncated cone-shaped or cylindrical.
Further improvement of the utility model is that described protective cover is the thin-wall metal cover.
The utility model temperature tube underpart opening is convenient to processing, reduces rejection rate.The conducting strip that temperature tube body bottom inner chamber is inlayed is by high heat conduction, high temperature resistant, erosion-resistant material manufacturing, conducting strip is through reconditioning processing, be processed into the round table-like accurately or cylindric lamellar body of thickness, conducting strip is mounted to temperature tube body bottom inner chamber, forms the temperature Perception Area of infrared measurement of temperature pipe.Protective cover is a thin-wall metal cover, and mainly in order to protect conducting strip, conducting strip can oxidation when guaranteeing that temperature tube carries out high-temperature baking with tundish before use, thereby guarantees that temperature tube has high thermometric response speed and serviceable life.Compared with prior art, the utlity model has following effect:
(1) the thermometric response speed of raising temperature tube, response time≤4min.
(2) improve serviceable life, serviceable life 〉=30 hour.
(3) reduce temperature tube manufacturing cost and use cost, because the temperature tube underpart opening is convenient to processing, reduce rejection rate, can reduce manufacturing cost, this temperature tube long service life can reduce use cost.
