Abstract
The utility model relates to a casting blank surface water vapor blower for infrared temperature measurement, which belongs to the technical field of the continuous casting equipment in the metallurgical industry and is used for eliminating high-temperature water vapor on the casting blank surface so as to realize accurate temperature measurement for the casting blank surface. In the technical scheme, the casting blank surface water vapor blower comprises a blow pipe and a compressed air chamber, wherein the blow pipe is a cylindrical pipe, the compressed air chamber is a circular chamber around the upper part of the blow pipe and is fixedly connected with the blow pipe, the cavity of the compressed air chamber is connected with a compressed air generator through a communicating pipeline, and a plurality of compressed air spray pipes are arranged between the cavity of the compressed air chamber and the cavity of the blow pipe and are uniformly arranged around the cavity of the blow pipe. With the blow pipe guiding the air flow to change the original flow field of the casting blank surface water vapor, compressed air in the compressed air chamber forms the jet pump effect in the cavity channel of the blow pipe through the compressed air spray pipe with a special angle, and the negative-pressure zone can be formed in the original water vapor zone to facilitate infrared energy radiation, thereby realizing the accurate temperature measurement of the infrared temperature measurement device.
Description
Technical field
The utility model relates to a kind of steam blow device that uses when being applied to measure casting blank surface temperature, belongs to metallurgy industry continuous casting installation for casting technical field.
Background technology
Continuous casting two cold is to the quality decisive role of strand.Most important in the various parameters of continuous casting two cold is exactly the feedback of casting blank surface temperature, and casting blank surface temperature plays directive function to other parameters of continuous casting (for example water distribution, pulling rate, liquid core length, the degree of superheat etc.).Domestic conticaster is implemented temperature measurement on-line at secondary cooling zone does not still have the report of application, and the way of conventional temperature feedback is still and manually adopts portable infrared temperature-measuring gun to carry out manual thermometric at times.The flexible operability of this method is good, but because continuous casting two cold adopts gas, water mixing to cool off, produces a large amount of steam at casting billet surface under the effect of high temperature strand.When carrying out infrared measurement of temperature superheated vapor influenced the strand infrared energy to external radiation, the accuracy of thermometric is impacted.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of when strand is carried out thermometric, can eliminate the superheated vapor of casting billet surface, makes thermometric infrared measurement of temperature casting billet surface steam purging device accurately.
The technical scheme that solves the problems of the technologies described above is:
A kind of infrared measurement of temperature casting billet surface steam purging device, it is made up of blowpipe, delivery air chamber, blowpipe is a cylindrical duct, delivery air chamber is an annular compartment, delivery air chamber is looped around the top of blowpipe, fixedlys connected with blowpipe, and the chamber of delivery air chamber has connecting pipe to be connected with compressed air generator, be connected with a plurality of compressed air jet pipes between the chamber of delivery air chamber and the blowpipe chamber, the compressed air jet pipe is uniform around the tube wall of blowpipe chamber.
Above-mentioned infrared measurement of temperature is with casting billet surface steam purging device, and described compressed air jet pipe is 4, compressed air nozzle axis and blowpipe axis in angle of 45 degrees, the compressed air nozzle axis becomes 35 to spend angles with the blowpipe tangent plane.
Adopt the infrared measurement of temperature casting billet surface steam purging device of this structure, flow by blowpipe guiding air, to change original casting billet surface steam flow field, the indoor compressed air of compressed air forms the jet pump effect by the compressed air jet pipe that special angle is arranged in the blowpipe cavity lane simultaneously, original steam zone forms little negative pressure region and is beneficial to the infrared energy radiation, to realize the accurate thermometric of portable infrared temperature measurement apparatus.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Mark is as follows among the figure: blowpipe 1, delivery air chamber 2, connecting pipe 3, infrared measurement of temperature observation port 4, blowpipe chamber 5, compressed air jet pipe 6.
The specific embodiment
Show among the figure that the utility model is made up of blowpipe 1 and delivery air chamber 2.
Blowpipe 1 is a cylindrical duct, and delivery air chamber 2 is an annular compartment, and delivery air chamber 2 is looped around the top of blowpipe 1, fixedlys connected with blowpipe 1.
The chamber of delivery air chamber 2 has connecting pipe 3 to be connected with compressed air generator, and the chamber of delivery air chamber 2 also is connected with blowpipe chamber 5.What be connected between the chamber of delivery air chamber 2 and blowpipe chamber 5 is a plurality of compressed air jet pipes 6, and they are uniform around the tube wall of blowpipe chamber 5.Embodiment among the figure shows, delivery air chamber 2 directly is fixed on the outer tube wall of blowpipe 1, the outer tube wall of blowpipe 1 also becomes a lateral compartment wall of delivery air chamber 2, and the compressed air jet pipe 6 that therefore connects the chamber of delivery air chamber 2 and blowpipe chamber 5 is the through hole on blowpipe 1 wall.
Show among the figure that described compressed air jet pipe 6 is 4, compressed air nozzle axis and blowpipe axis in angle of 45 degrees, the compressed air nozzle axis become with the blowpipe tangent plane 35 the degree angles.
During the utility model work, the compressed air of compressed air generator enters delivery air chamber 2 by tube connector 3, carries out uniform distribution by delivery air chamber 2.For guarantee air-flow evenly simultaneously for satisfy in be formed centrally negative pressure institute air demand requirement it is divided into is 4 strands of air-flows, the compressed air jet pipe has carried out special angle design simultaneously:
1, the compressed air nozzle axis becomes the downward angle of 45 degree with the blowpipe axis, has formed air flow field from top to bottom in the blowpipe chamber 5, can guarantee thus to suck the not air of moisture vapor by blowpipe chamber 5 tops, reduces the influence of steam fog to infrared measurement of temperature.
2, the compressed air nozzle axis becomes 35 degree angles with the blowpipe tangent plane, forms the rotary air flow field in blowpipe chamber 5, has played the effect of steady air flow; Form little negative-pressure vacuum district in lumen near axis zone simultaneously, be beneficial to infrared ray and penetrate, reduce the loss of air, realize accurate thermometric infrared energy in this zone.
