Description
Technical field
The invention belongs to continuous cast mold and use utility appliance, be specifically related to a kind of continuous cast mold centering measurement mechanism.
Background technology
The strand of continuous casting installation for casting production is the starting material of steel rolling, and the quality of strand directly influences the quality of final products, and the crystallizer very important parts that are conticasters are ingot moulds of the no end of a Forced water cooling, can be described as " heart " of continuous casting installation for casting.The precision that continuous cast mold is installed directly has influence on the quality of strand.Especially first backing roll in the fan-shaped top of O (hereinafter to be referred as first backing roll) of wide sufficient roller of crystallizer and bending section is a key factor that influences cc billet surface quality to the arc precision; And in a single day the arc deviation is transfinited, also can cause the serious production safety accident of this type of bleed-out to take place.
At present the conticaster of steelworks is many is provided by VAI industrial group (hereinafter to be referred as VAI), to the arc precision has been provided clear and definite requirement, and special-purpose centering measurement mechanism is provided.The continuous cast mold centralising device that VAI provides is manual, and its critical part is the sounding rod that spirit level is equipped with in a upper end; The sounding rod lower end is provided with two armature devices, and upper armature is aimed at the sufficient roller side face of crystallizer, and lower armature is aimed at the first backing roll side face; Make the straight-bar swing through armature suction, if sufficient roller does not align with first backing roll, the bubble in the spirit level just flows on one side so, if aimed at, bubble will be in the center.
The centralising device that VAI provides; The moving range estimation of armrest fully; Bubble position through the range estimation spirit level judges whether centering, can't show the deviation of position between the sufficient roller and first backing roll, and the amount of deflection between the two is extremely important for continuous casting process; If can not be controlled in the specialized range, cause potential safety hazard can for whole technology.The field engineer feels that generally this device operation is very inconvenient in addition; Owing to can not provide effective deviate; Be difficult to installing and locating crystallizer accurately, so the adjustment time is long and workload is big, these problems have seriously hindered safety, production work efficiently.
Summary of the invention
The present invention is intended to overcome the prior art defective, and purpose provides a kind of continuous cast mold centering measurement mechanism that can measure quickly and accurately.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is: this device comprises sensor, test rod, carriage, support adjustment rack and digital display meter.Installing plate is fixed on the housing in the carriage, and the lower plane of installing plate is vertical with the center line of housing, and installing plate is fixed on the platform that supports adjustment rack through fastening bolt; Detect worm and wheel and be installed in concentrically in the housing, the lower end of test rod is equipped with sensor, and sensor is connected with digital display meter through cable.
The structure of carriage is: worm screw passes through Bearing Installation in housing; The worm and wheel engagement, the interior circle of worm gear is processed with internal thread, and test rod is provided with slide block topmost; On the test rod at slide block lower plane 30～50mm place, be processed with external thread, worm gear and test rod are thread connection; The upper surface of worm gear and lower surface are equipped with thrust bearing and following thrust bearing respectively, and the lower surface of the upper surface of last thrust bearing and following thrust bearing is equipped with back-up block and following back-up block respectively; Test rod, worm gear, go up thrust bearing, down thrust bearing, go up back-up block and following back-up block all with the concentricity installation of housing.
In the present technique scheme: sensor or be ultrasonic sensor or for laser sensor; The housing side of being tubular, square tubular is made up of " recessed " body and another " recessed " body; Housing upper end hollow parts is a slideway, and slide block is installed in the slideway, and the xsect of slide block is identical with the xsect of slideway, is square; Be respectively equipped with on the test rod and measure outer parapodum roller and measure pairing mark I-II of lateral branch runner and III-IV; Supporting adjustment rack is the special-purpose The Cloud Terrace of video camera or camera, and level meter is arranged on the The Cloud Terrace.
The measuring method of continuous cast mold centering measurement mechanism is:
The first step is placed on the platform of crystallizer supporting adjustment rack, through the adjustment handle, makes the level vial centering adjustment that supports on the adjustment rack, then the fixed support adjustment rack;
Second step made the worm-gear driven test rod to lower slider through the turn worm screw, and when mark I-II skidded off the lower surface A of housing, record is the corresponding outer parapodum roller of section and the reading of the distance L 2 between sensor therewith, gets minimum value wherein;
The 3rd step continued to lower slider the worm-gear driven test rod through the turn worm screw, and when mark III-IV skidded off the lower surface A of housing, record is the corresponding lateral branch runner of section and the reading of the distance L 1 between sensor therewith, gets minimum value wherein;
In the 4th step, what calculate outer parapodum roller and lateral branch runner is Δ L=L2-L1 to arc, moves crystallizer to the left or to the right with adjustment Δ L, if Δ L is less than or equal to 0.3mm, explains and aims at;
In the 5th step, if Δ L greater than 0.3mm, then repeats first to fourth step, L is less than or equal to 0.3mm until Δ.
Owing to take technique scheme, the present invention is directed to the manual centralising device that existing VAI provides, the adjustment handle with on the supporting adjustment rack guarantees that orthogonal two detection sides are in the center to the bubble of level meter.After the adjustment test rod is fixed on the upper support plane of supporting adjustment rack, the sensor that will be fixed on the test rod lower end simultaneously is connected through cable with digital display meter.Rotary worm; Through the worm and gear motion test rod is slided up and down; Can pickup from digital display meter relatively outside the distance of parapodum roller and lateral branch runner periphery; For the work to arc of crystallizer provides numerical basis, so just can carry out autotelic adjustment, can crystallizer be in place accurately and rapidly.
The advantage of this device is: first; Directly provided the distance of outer relatively parapodum roller of sensor and lateral branch runner; On-the-spot staff can be easy to confirm the direction and the size of crystallizer adjustment, the adjustment time of having practiced thrift crystallizer greatly through the data on the digital display meter; The second, adopt the worm and gear structure, make data acquisition more effective, the screw thread pair of worm gear and sounding rod also can make the device self-locking, prevents that sounding rod from gliding because of deadweight; The 3rd, easy to operate, be easy to safeguard, only need the sensitivity of inspection sensor to use for a long time.
