Abstract
The utility model provides a high pressure water descaling effect detection apparatus, comprising a framework being adjustable in length, width, and height and four upper and lower working planes for measuring the high pressure water descaling impact effect. The framework is capable of simulating the length, width, and height of different slabs. Supporting frames and a positioning device are mounted and fixed by bolts to support the working planes at calculated positions of the framework. Taking advantage of the production interval time or maintenance time, the apparatus is pushed into a descaling system to be detected and is withdrawn after enabling high pressure water to inject on the working planes for 1-2 seconds. Observations are made in terms of the shape, width, length, depth, and angle of impact traces on the working planes as well as the degree of overlapping of two adjacent traces along the rolling direction, thereby detecting whether a nozzle is normal or not. The apparatus employs a size-adjustable compound structure so that the apparatus is capable of simulating the shapes of the slabs of various specifications and performing the on-line detection of the high pressure water descaling nozzle impact effect for multiple production lines. The apparatus is relatively light and is convenient to operate. The apparatus improves the field working efficiency.
Description
Technical field
The utility model is particularly related to a kind of pick-up unit at operation of rolling mesohigh water scale removal effect, in particular for the detection of descaling jet.
Background technology
In course of hot rolling, oxidation can occur through the heating rear surface in slab, generates one deck iron scale; Roughing and finish rolling descaling system Main Function are exactly the iron scale of removing steel slab surface, are the key equipments of control surface quality of steel.
In the prior art, the device that detects water nozzle is also arranged, be ZL200820303385 " high-pressure water descaler water nozzle pick-up unit " such as the patent No., although this device can detect the duty of water nozzle, but have following shortcoming: the material that 1) is used for testing is plastic plate, and is insensitive to the hitting power test." vinyon plate or other have the two retable offset plates that certain plasticity and strength materials are made " described in the embodiment, plastic material does not have resilient material to be quick on the draw such as it.2) framework is fixed, neatly transform length, width and height.3) detection time relatively long, can not simulate better industry spot, use plastic material generally to need the high-pressure water jet of several seconds, and use rubber peel (resilient material) only to need 1-2s, then the simulated field slab is actual better overwhelms the time.
The utility model content
The purpose of this utility model mainly provides descaling jet on-line measuring device in a kind of roughing and the finish rolling descaling system, can utilize time or the repair time in production gap that the duty of roughing and finish rolling descaling jet is carried out On line inspection, judge rapidly corresponding nozzle and whether work, and framework can be simulated different slab length, width and thickness.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
This device comprises length, width and adjustable for height framework and rubber peel, mounting and positioning device on the described framework.In lengths of frame, beat bolt hole according to required size on the Width, its framework is plug-type angle steel group frame, change length and the width of framework with the fixing method of bolt, support frame is beaten bolt hole according to required size on short transverse, its framework is plug-type angle steel group frame, change the height of bracing frame with the fixing mode of bolt, changing the lengths of frame fundamental purpose is the detection of determining the position of locating device and satisfying dissimilar descaling mill nozzle, change frame width and simulate the width of different slabs, change the support frame height and simulate different slab thicknesses, rubber peel is resilient material, hitting power is sensitiveer for detecting, and rubber peel is installed on the support frame corresponding with descaling jet, and rubber peel thickness is 8-15mm, during detection, locating device is fixed on the de-scaling entrance casing upper section.
Compare with prior art, the beneficial effects of the utility model are at least: 1) use the sensitiveer resilient material of hitting power reflection to detect, detect effective; 2) length of framework can be adjusted according to the position of the position of locating device and nozzle, width and highly can be according to the adjusted size of slab; 3) detection time short, can simulate better the commercial production scene.

Embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described further.
As shown in Figure 1 and Figure 2, general frame can be simulated slab thickness and the width of different phase, and slab is of a size of example during here mainly with a de-scaling (thickness 220mm * width 1350mm) and secondary descaling steel (thickness 40mm * width 1350mm):
(1) slab of simulated thickness 220mm * width 1350mm.On-the-spot determine locating device 6 and support frame 7,8,9,10 position by the length that changes framework 3, the handy bolt of its length adjustment is fixed; Framework 3 width adjustment are fixed with bolt to width of plate slab 1350mm; Adjust at thickness direction go forward, the height of lower front support framework, making gross thickness is 220mm, fixes with bolt; In like manner, in the adjustment after, the height of lower rear support framework, making gross thickness is 220mm, fixes with bolt.
(2) slab of simulated thickness 40mm * width 1350mm.On-the-spot determine locating device 6 and support frame 7,8,9,10 position by the length that changes framework 3, the handy bolt of its length adjustment is fixed; Framework 3 width adjustment are fixed with bolt to width of plate slab 1350mm; After on thickness direction is adjusted, the height of lower rear support framework, making gross thickness is 40mm, fixes with bolt; In like manner, in the adjustment after, the height of lower rear support framework, making gross thickness is 40mm, fixes with bolt.
During the normal detection of this device stationary installation is fixed on the de-scaling entrance casing upper section, makes this device when normal operation, play not occur, increase the stability of device and the accuracy of detection.Go forward rubber peel workplace 1 and upper rear rubber peel workplace 4 each be separately fixed on the support frame 7,9 with bolt, and workplace is in the spray regime of descaling system upper header nozzle, lower front rubber peel workplace 2 and lower rear rubber peel workplace 5 respectively are separately fixed on the support frame 8,10 with bolt, and workplace is in the spray regime of descaling system lower collector pipe nozzle.
Utilize time or the repair time in production gap this device to be pushed in the descaling system of required detection, start descaling system, water ejection beginning timing, slab is actual in descaling system to be impacted the time in order to simulate, 1-2 stops to spray water second, extract this device out, by observing the shape of the strike vestige on the workplace, width, length, the degree of depth, angle and two adjacent vestiges are along the degree of overlapping of rolling direction, the field personnel just can know very soon whether descaling spray nozzle work is normal, and wearing and tearing and stopping state, in order in time change abnormal nozzle, improve the high-pressure water descaling effect.
