Description

A kind of contact casting blank surface temperature measurement apparatus
Technical field
The utility model is related to continuous casting technology field, more particularly to a kind of contact casting blank surface temperature measurement apparatus.
Background technology
In continuous casting production process, the continuous casting billet skin temperature of two cold-zones has for secondary cooling water control and slab quality control It is significant.The quality of continuous casting billet cooling effect can not only be analyzed according to continuous casting billet skin temperature, and it can be made Cooling water inflow is controlled for the control input parameter of two cold-zone cooling control systems, continuous casting billet is avoided fragility in aligning area Area, so as to improve slab quality.
For Inspection Research result or adjustment production technology, manufacturing enterprise will be to the temperature of secondary cooling area for continuous casting in one's power for Research Center Degree is measured, and especially aligning region casting blank surface temperature is measured.At present, it is main to the surface temperature measurement of strand Using contactless infra-red radiation method.Multi-group data is measured in the range of certain time with infrared temperature instrument, takes it maximum The method of value, its measurement accuracy is of a relatively high.But because infrared ray requirement that infrared radiation thermometer is sent vertical irradiation of trying one's best exists The surface of testee could staff needs hand-held infrared radiation thermometer station to arrive closer to accurate measured value, therefore during measurement Above strand on straightening roller mechanism, thermometric operation could be carried out to casting billet surface, therefore there is great potential safety hazard.
Meanwhile,, can only be to fan-shaped section and fan-shaped section exposed portion due to being limited by conticaster labyrinth in measurement Casting billet surface carry out thermometric, and the gap between fan-shaped section and fan-shaped section is smaller, generally only 10~20 centimetres and gap Between be often additionally provided with resistant to elevated temperatures rubber cover plate, bring extreme difficulties to thermometric work, many people generally required during measurement and are coordinated It could complete to measure work.
In addition, when the strand to aligning area is measured, due to having carried out water-spraying control to strand, depositing casting billet surface In a large amount of water smokes, these water smokes can absorb, reflect and scatter the energy of casting billet surface radiation, the accuracy of measurement is dropped significantly It is low.
In order to eliminate influence of the water smoke to measurement result, Authorization Notice No. is CN201644739U Chinese patent, open " a kind of casting blank surface water vapor blower for infrared temperature measurement ", it is made up of blowpipe, delivery air chamber, and air is guided by blowpipe Flowing, is radiated beneficial to infrared energy with dispelling casting billet surface water smoke, realizes accurate thermometric.Although the technical scheme can solve the problem that water Interference of the mist to thermometric, but introduce after compressed air purging, the reduction of casting blank surface temperature will certainly be caused, this is unfavorable for pair The accurate measurement of strand temperature.Meanwhile, the cold-zone narrow space of conventional slab caster two is also unfavorable for the placement of purging device, specifically grasped There is certain difficulty in work.
The Chinese patent of Application No. 200710093063.6, discloses a kind of " high temperature casting billet surface temperature under water fog medium The measuring method of degree ", the water smoke concentration for measuring high temperature casting billet surface by air water smoke concentration sensor is transferred to remote computation Machine, obtains water smoke under the concentration by the relation curve between water fog medium and the attenuation coefficient of radiation energy by remote computer and is situated between The attenuation coefficient of confrontation radiation energy, the temperature tested using the emissivity of the attenuation coefficient and casting billet surface oxide-film temperature measurer Data are modified and measured in real time the true temperature of the casting billet surface under water fog medium.The weak point of this technical scheme exists In:The surface temperature of strand is measured indirectly by measuring water smoke concentration, and water smoke concentration is by environment temperature, nozzle operation state Influence than larger, this all can produce error to measurement result.
The Chinese patent of Application No. 03153364, discloses a kind of " continuous casting aligning target temperature monitoring and controlling and analysis System ", in order to avoid the interference of medium, strand straightening point temperature is measured from the infrared probe of 1~1.1 micron wave length.Due to Strand is 900 DEG C~1200 DEG C in straightening point surface temperature, bent according to the relation of wavelength under condition of different temperatures and spectral energy Line understand, corresponding peaks wavelength be 0.7~1.0 micron, 1~1.1 micron wave length section when, spectroscopic capabilities with temperature change Tend towards stability, be unfavorable for the raising of measurement accuracy.
From the point of view of the technical scheme announced at present, the measurement to the cold-zone casting blank surface temperature of slab two mostly uses infrared Temperature measurer coordinates goes water smoke device or other contactless indirect thermometric modes accordingly.These thermometric modes, which all exist, necessarily asks Topic and shortcoming, one be infrared measurement of temperature by water smoke interference it is big, then again can be to the surface temperature of strand if installing water smoke device additional Influence is produced, easily makes measurement result distortion;Two be when being measured by Portable infrared temperature measurement instrument, it is necessary to many people coordinate station in sky Between could complete measurement on narrow and small withdrawal straightening machine, this brings great potential safety hazard to measurement, and often due to the big temperature of water smoke Degree is high, and survey crew can not complete to measure work;Three be to measure casting blank surface temperature indirectly by measuring water smoke concentration, its water Mistiness degree is protected from environmental and the influence of nozzle operation state is than larger, is also easily caused measurement result distortion.Four be above-mentioned measurement The structure of device is all more complicated, and equipment cost is high, installs difficult in maintenance.
