Abstract
The utility model relates to an instrument for measuring openings and back tapers of crystallizers. The utility model is composed of a tensioning mechanism, a displacement transducer mechanism, a vertical position measuring mechanism and a handle. The values of the opening and the back taper of the measured crystallizer are directly displayed on line without positioning and referencing in the process of measuring. The utility model has the advantages of time saving and convenient operation.
Description
The utility model relates to the particularly measuring instrument of continuous cast mold opening degree and back draught of a kind of crystallizer.
The precision of crystallizer opening degree and back draught is very crucial to the influence of the quality of strand, and is excessive as the conticaster crystallizer dimensional discrepancy, occurs easily that steel billet skids or bleed-out not only influences slab quality and also industrial accident may occur.So the opening degree of crystallizer and the detection of back draught are very important.The at present domestic slide calliper rule hand dipping of normally using is promptly measured the opening size of the suitable for reading and end opening of crystallizer with slide calliper rule, calculate its back draught according to certain any the altitude gauge that will survey then.Error ratio is bigger like this, and precision is lower, and operation is also inconvenient.Abroad be to adopt sensor to add the mode of registering instrument, measure, the curve on the contrast of the data after the test coordinate is conversed the value of crystallizer opening degree and back draught, and in use positioning reference must be arranged.
The purpose of this utility model provides a kind of instrument of measuring crystallizer opening degree and back draught, and the energy direct-on-line demonstrates the value of crystallizer opening degree and back draught when measuring, and need not look for positioning reference, and is easy to use, saves time.
For achieving the above object, the utility model adopts following structure, and it is by the measuring instrument body, the tensioning guiding mechanism, and displacement transducer mechanism, the lengthwise position measuring mechanism, handgrip is formed.The measuring instrument body is that I-groove is equipped with two groups of tensioning guiding mechanisms in the Qi Sijiao symmetry, it is moved in crystallizer reposefully, displacement transducer mechanism is contained in body I-groove middle part, be in the middle of upper and lower two groups of tensioning guiding mechanisms, two displacement transducers are in same center line, symmetry is installed, during detection during gauge head contact crystallizer wall sensor send electric signal and be transferred to the instrument that has microcomputer and calculate, show the opening degree value.When needs were measured certain any back draught, measuring instrument continued to move down, and pulse is sent in the scrambler rotation in the lengthwise position mechanism, the number of turns according to rotation is measured fore-and-aft distance, send 50 pulses as rotary encoder, its rotation half-turn just, the gauge head 50mm that moves down.The transversal displacement of writing down this point again i.e. the opening degree of this point, and these data are input to simultaneously in the secondary instrument of band microcomputer and calculate, and directly show and print the value of the opening degree and the back draught of this point.Calculate the back draught value by following formula
Δ＝ (S
1-S
2)/(S
1) × 1/(h) ×100％
In the formula: S=H+L
1+ L
2H is the width L of crystallizer itself
1And L
2It is the distance between two displacement transducer gauge heads and the crystallizer wall.S is the opening degree of crystallizer, S
1Be upper shed degree, S
2Be the under shed degree.H is S
1With S
2Between fore-and-aft distance.
Advantage of the present utility model is to use this apparatus measures opening degree back draught.Can directly show and print its value, when measuring, need not positioning reference, easy to use, save time, and the measuring accuracy height.

In conjunction with the accompanying drawings the utility model is described in further detail.For making measuring instrument in measurement, keep balance, four jiaos four groups of tensioning structures are installed at measuring instrument body I type groove, it comprises four rolling axles 6 and eight running rollers that are installed on the rolling axle, rolling axle makes the rolling axle 6 that links bearing pin 8 move in copper sheathing 9 under the effect of spring 10, the elastic force of compression spring 10 makes running roller be pressed against crystallizer wall and moves up and down.Sensor mechanism is to overlap 12 sensor overcoat end caps 13, gauge head spring 14, sensor overcoat 15 by gauge head 11, gauge head, and clamping plate 16 high accuracy displacement sensors 17 are formed.Sensor mechanism links to each other with body by sensor overcoat end cap, and sensor is fixed on the measuring instrument body by clamping plate 16.The sensor internal coil sent electric signal when compression spring 14 made two gauge heads press crystallizer wall simultaneously during measurement, was transferred to the secondary instrument that has microcomputer.Calculate, show.Need measure the fore-and-aft distance of this point when measuring certain some back draught, this is realized by the lengthwise position measuring mechanism that is contained on the body, along with moving down of measuring instrument, runner 19 is close to the crystallizer wall to begin to rotate, scrambler 21, constantly send pulse value,, determine the fore-and-aft distance of certain point according to the number of turns of scrambler rotation.Send 50 pulses as rotary encoder, the rotation half-turn, the gauge head 50mm that moves down writes down the opening degree of this point, by top formula as calculated the machine computing can demonstrate the crystallization opening degree and the back draught value of this point.Measure and finish to reset by spring leaf 24, scrambler is fixed on the measuring body body by hinge 23 by the front and back limiting plate.Add 18 protections of scrambler outer cover.
Claims (2)
1, the measuring instrument of a kind of crystallizer opening degree and back draught is characterized in that it is by the measuring instrument body, the tensioning guiding mechanism, and displacement transducer mechanism, the lengthwise position measuring mechanism, handgrip is formed.
2, measuring instrument according to claim 1 is characterized in that:
