Abstract
A continuous-casting billet cutting length measuring device mainly comprises a casting billet cutting machine, a mechanical measuring wheel connected with the casting billet cutting machine and a reader connected with the mechanical measuring wheel, at least two pairs of photoelectric sensors are symmetrically mounted on the two sides of a roller way of the casting billet cutting machine and are connected with a computer through signal lines, the computer is connected with a PLC through signal lines, and the PLC is connected with the mechanical measuring wheel through signal lines. According to the continuous-casting billet cutting length measuring device, the length measuring precision error of a casting billet can be reduced to +/-20 mm from 80 mm, the casting billet is prevented from being too long or too short, the length qualified rate of the casting billet is improved, quality objection is reduced, the structure is simple, steel material consumption is reduced.
Description
Technical field
The utility model relates to a kind of measurement mechanism, specifically belongs to a kind of continuous casting billet Cutting Length measurement mechanism.
Background technology
Strand length-measuring appliance is the key device that continuous casting is produced cut deal, heavily had the steel grade strand sizes such as high added value steel grade, boiler steel, bridge steel, special steel, the deck of boat, container steel of specific (special) requirements accurately to control base, to control reduce after the short chi of operation strand, overlength equal-specification do not conform to problem and play a crucial role.One of important measures that reduce iron and steel stock consumption.In the prior art, often there is the problems such as strand size overlength or short chi.Hot rolling material, owing to being hot-loading and hot-conveying, causes the overweight situation that causes surpassing crane or reel load at client's harbour of coil of strip.Generally take at present constantly maintenance to adjust strand meter wheel both at home and abroad, keep meter wheel precision to address this problem.But because mechanical measurement wheel is arranged on casting machine pulling-straightening roller, rotate the number of turns calculate the length that strand passes through by roller girth, the method is mechanical measurement, and working condition is 1000 ℃ of red heat strands, and casting billet surface has the mixture of iron scale and crystallizer protecting residue.Casting machine pulling-straightening roller belongs to the place of the frequent accumulated slag of high temperature; the bearing of straightening simultaneously belongs to the roller of stressed maximum, and bearing breaks down or pulling-straightening roller surface accumulated slag, and the roller turn number of turns and roller girth all change; cause the strand length of casting machine mechanical measurement wheel measurement to have error, be greater than ± 30mm of error.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, provide a kind of can be by strand linear measure longimetry trueness error from ± reduce to ± 20mm of 80mm, prevent strand overlength or ultrashort, improve strand length qualification rate, reduce quality objection, continuous casting billet Cutting Length measurement mechanism simple in structure.
Realize the technical measures of above-mentioned purpose:
Continuous casting billet Cutting Length measurement mechanism, mainly by strand cutting machine, the mechanical measurement that is connected with strand cutting machine, take turns, take turns with mechanical measurement the reader being connected and form, it is: the roller-way bilateral symmetry at strand cutting machine is installed at least two pairs of photoelectric sensors, photoelectric sensor is connected with computer by holding wire, computer is connected with PLC controller by holding wire, and PLC controller is connected with mechanical measurement wheel by holding wire.
It is characterized in that: on strand cutting machine, be provided with 0 locating piece, from the distance of the nearest a pair of photoelectric sensor of 0 locating piece, be no less than 5 meters; Spacing between every two pairs of adjacent photoelectric sensors is not less than 0.5 meter.
Feature of the present utility model is: can prevent strand overlength or ultrashort by strand linear measure longimetry trueness error from ± reduce to ± 20mm of 80mm, improve strand length qualification rate, reduce quality objection, and simple in structure, and reduce iron and steel stock consumption.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
In figure: 1-strand cutting machine, 2-mechanical measurement wheel, 3-reader, 4-photoelectric sensor, 5-holding wire, 6-computer, 7-PLC controller, 8-0 locating piece.
The specific embodiment
Below in conjunction with accompanying drawing, be described further:
Continuous casting billet Cutting Length measurement mechanism, mainly by strand cutting machine 1, the mechanical measurement that is connected with strand cutting machine 1, take turns 2, take turns 2 readers that are connected 3 with mechanical measurement and form, its roller-way bilateral symmetry at strand cutting machine 1 is installed at least two pairs of photoelectric sensors 4, photoelectric sensor 4 is connected with computer 6 by holding wire 5, computer 6 is connected with PLC controller 7 by holding wire 5, and PLC controller 7 is connected with mechanical measurement wheel 2 by holding wire 5.
It is also provided with 0 locating piece 8 on strand cutting machine 1, from the distance of the nearest a pair of photoelectric sensor 4 of 0 locating piece 8, is no less than 5 meters; Spacing between every two pairs of adjacent photoelectric sensors 4 is not less than 0.5 meter.
Operating principle
When the photoelectric sensor 4 of strand by roller-way, it is long that the light velocity very accurately reacts ejection very soon, read the counting of the reader 3 on mechanical meter wheel 2 simultaneously, can calculate mechanical measurement and take turns 2 counting errors, by the quick error of calculation correction value of computer 6, zero clearing simultaneously, both static photoelectric sensor 4 pin-point readings had been obtained, simultaneously mechanical measurement is taken turns 2 zero clearings, and after calibration error, short distance is measured longly less than the base of 1 meter, and error narrows down to original 25% left and right.
This specific embodiment only exemplifies for the best, not the restricted enforcement to technical solutions of the utility model.
