A kind of continuous casting secondary cooling water spray equipment installation accuracy detection method, adopt Special ruler to detect off-line or online continuous casting segment secondary cooling water water nozzle bracket and installation site and the angle of water nozzle, by the detection method of three-point fix, realize the accurate installation of secondary cooling water water nozzle.Its concrete grammar and step are:
1, make scale:
Described scale is comprised of rule, benchmark frame, torque nut and backstay; The blade of cylindrical rule is marked with scale, and hollow type benchmark frame is vertically connected on rule by torque nut, and benchmark frame two ends respectively activity are fitted with drawing and pulling type backstay, and backstay linkage section is with fixing scale, and free segment is provided with arc-shaped slot;
While 2, detecting, by the fixedly scale of backstay linkage section, the symmetrical collapsing length of adjusting two backstays, guarantees that the arc-shaped slot of backstay free segment is tightly fitted on adjacent two rollers of the same row of fan-shaped section, makes rule vertically between two rollers; Rule initiating terminal is stretched between two rows roller, make rule initiating terminal exceed secondary cooling water water nozzle end 3-5mm, then scale is fixed;
3, by being positioned in the middle of adjacent two rollers of the same row of fan-shaped section and perpendicular to the rule of the line of two roller axis, check that whether secondary cooling water water nozzle bracket is parallel with rule, if parallel, the setting angle that secondary cooling water water nozzle bracket is described is perpendicular to strand direction, meets installation code; If not parallel, need to adjust;
4, check that whether the line between secondary cooling water water nozzle bracket axis and rule axis is parallel to the body surface of roller, as parallel, illustrates that secondary cooling water water nozzle is in the middle of two rollers on upright position, meets installation code; If not parallel, need to adjust;
5, by the scale of rule, determine that whether secondary cooling water water nozzle meets equipment requirement standard apart from the vertical range of adjacent two roll axis plane of living in, does not need to rectify and improve in time if met yet;
6,, after detecting by above-mentioned three-point fox method, if secondary cooling water water nozzle bracket meets standard-required completely, it is qualified that the secondary cooling water water nozzle bracket that this fan-shaped section is described is reorganized and outfit, the production of can using or reach the standard grade at any time; If wherein there is one not meet, can assert that this secondary cooling water water nozzle bracket reorganizes and outfit defectively, the production of can not using or reach the standard grade, need to rectify and improve until qualified.
Described benchmark frame transversal section is rectangle.
Beneficial effect of the present invention is:
The inventive method is simple, convenient operation, and accuracy of detection is higher, can meet completely and install and use standard-required, realization is carried out quantitative detecting and assessing to reorganizing and outfit rear or online fan-shaped section secondary cooling water water nozzle and kerb weight and the installation accuracy of support, the installation of each secondary cooling water water nozzle bracket in unified standard fan-shaped section, thus the stability of secondary cooling water spray system and the homogeneity of slab cooling guaranteed, improve surface and the internal soundness of strand.

Embodiment
Continuous casting secondary cooling water spray equipment installation accuracy detection method of the present invention, system adopts Special ruler to detect off-line or online continuous casting segment secondary cooling water water nozzle bracket and installation site and the angle of water nozzle, realizes the accurate installation of secondary cooling water water nozzle by the detection method of three-point fix.
Its concrete grammar and step are:
1, make scale:
Scale is comprised of rule 1, torque nut 2, benchmark frame 3 and backstay 4, adopts aluminium material matter to make.Rule 1 is a right cylinder, is carved with length scale on the blade of rule 1; Benchmark frame 3 is the rectangular parallelepiped sleeve pipe of a hollow.Backstay 4 is two, size and the shape of two backstays 4 are identical, and backstay 4 consists of two sections of linkage section and free segments, on linkage section with fixing scale 6, free segment is provided with arc-shaped slot 5, and the radian of arc-shaped slot 5 is determined according to the diameter of fan-shaped section roller is corresponding.
Benchmark frame 3 is vertically connected on rule 1 by torque nut 2, and the position of benchmark frame 3 can be adjusted by torque nut 2, unclamps the position that torque nut 2 gets final product upper and lower play benchmark frame 3.The linkage section of two backstays 4 is inserted respectively to the scale that forms the present invention in benchmark frame 3 from two ends, and backstay 4 can be adjusted collapsing length by pull.
While 2, detecting, by the fixedly scale 6 of backstay 4 linkage sections, the symmetrical collapsing length of adjusting two backstays 4, guarantees that the arc-shaped slot 5 of backstay 4 free segments is tightly fitted on adjacent two rollers of the same row of fan-shaped section, makes rule 1 vertically between two rollers; Again rule 1 initiating terminal is stretched between two rows roller, and make the initiating terminal of rule 1 exceed secondary cooling water water nozzle end 4mm, then scale is fixed.
