Abstract
The utility model provides a continuous casting secondary cooling water spray device installation accuracy detection scale which is formed by a graduated scale, a reference frame, a torsion nut and a positioning rod. A body of the cylindrical graduated scale is marked with scales. The hollow type reference frame is vertically connected to the graduated scale through the torsion nut. Two ends of the reference frame are movably inserted with a pull positioning rod respectively. Positioning rod connecting sections are provided with fixed scales, and positioning rod free sections are provided with arc-shaped clamp grooves. A special scale is utilized to detect and evaluate installation positions and angles of an off-line or online continuous casting fan-shaped section secondary cooling water nozzle bracket and a water nozzle, the installation of each secondary cooling water nozzle bracket in a fan-shaped section can be unified and standardized, thus the stability of a secondary cooling water spray system and the uniformity of casting blank cooling are ensured, and the improment of surface and internal quality of a casting blank is facilitated.
Description
Technical field
The utility model belongs to detection utensil field, relates in particular to a kind of scale that is specifically designed to continuous casting segment secondary cooling water (secondary cooling water) water nozzle and the detection of support installation accuracy.
Background technology
The spraying effect of continuous casting segment secondary cooling water directly has influence on the quality of strand, and wherein whether to meet standard then be one of key factor that directly affects spraying effect for the installation site of secondary cooling water water nozzle and support and angle.
Find in the produced on-site process, because installing, some water nozzle has certain angular deviation and vertical range deviation, therefore make the continuous casting segment secondary cooling system unstable, and cause slab cooling inequality and surface temperature uneven phenomenon, thereby cause the problems such as the strand width is unusual, underbead crack increases the weight of.
And for rolling off the production line through the fan-shaped section after reorganizing and outfit, because it is different to reorganize and outfit the standard implementation dynamics, so the installation situation of its each secondary cooling water water nozzle bracket also there are differences, but can't carry out quantitatively calibrating and accurate evaluation to it again at present.The use of in a single day reaching the standard grade of such fan-shaped section will exert an influence to the stability of whole secondary cooling water spray system, and and then has influence on the stable of slab quality.
Summary of the invention
The utility model aims to provide a kind of simple in structure, and accurately reorganizing and outfit and installation situation of detecting and assessing secondary cooling water water nozzle bracket improved the continuous casting two cold water spray system installation accuracy of reorganizing and outfit with installation accuracy and detected scale.
For this reason, the solution taked of the utility model is:
A kind of continuous casting two cold water spray system installation accuracy detects scale, it is characterized in that 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 the rule by torque nut, and benchmark frame two ends respectively activity are fitted with the drawing and pulling type backstay, and the backstay linkage section is with fixing scale, and free segment is provided with arc-shaped slot.
Described benchmark frame transversal section is rectangle.
The beneficial effects of the utility model are:
The utility model is simple in structure, accuracy of detection is higher, can realize carrying 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, thereby guarantee the stability of secondary cooling water spray system and the homogeneity of slab cooling, improve surface and the internal soundness of strand.
Description of drawings
Fig. 1 is the scale front view.
Fig. 2 is the scale front view that backstay is extracted state out.
Among the figure: rule 1, torque nut 2, benchmark frame 3, backstay 4, draw-in groove 5, fixing scale 6.
Embodiment
The utility model continuous casting two cold water spray system installation accuracy detects scale, is comprised of rule 1, torque nut 2, benchmark frame 3 and backstay 4.Rule 1 is a right cylinder, is carved with the 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 is made of two sections of linkage section and free segments, on the linkage section with fixing scale 6, free segment is provided with arc-shaped slot 5, and the radian of arc-shaped slot 5 is corresponding definite according to the diameter of fan-shaped section roller.
Benchmark frame 3 is vertically connected on the rule 1 by torque nut 2, and the position of benchmark frame 3 can be adjusted by torque nut 2, namely unclamps the up and down position of play benchmark frame 3 of torque nut 2.The linkage section of two backstays 4 is inserted respectively the scale that namely forms the present invention in the benchmark frame 3 from two ends, and backstay 4 can be adjusted collapsing length by pull.
During detection, fixedly scale 6 by 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 tightly is 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 the two rows roller, and make the initiating terminal of rule 1 exceed secondary cooling water water nozzle end 4mm, then scale is fixed, carry out the respective items visual inspection and survey.
The one, whether by being positioned in the middle of adjacent two rollers of the same row of fan-shaped section and perpendicular to the rule 1 of the line of two roller axis, it is parallel to detect the relative side of secondary cooling water water nozzle bracket and rule 1; The 2nd, by rule 1, check whether the line between secondary cooling water water nozzle bracket axis and rule 1 axis is parallel to the body surface of roller; The 3rd, determine by the scale of rule 1 whether the secondary cooling water water nozzle meets the equipment requirement standard apart from the vertical range on plane of living in, two roller centers.If the secondary cooling water water nozzle bracket meets standard-required fully, it is qualified that the secondary cooling water water nozzle bracket that this fan-shaped section then is described is reorganized and outfit, the production of can using or reach the standard grade at any time; If wherein have one not meet, then rectify and improve until qualified.
