Description
Technical field
The utility model relates to steel rolling high-pressure water descaling technical field, particularly relate to a kind of have protection nozzle function water under high pressure header device.
Background technology
High-pressure water descaling technology is requisite technology during hot-strip is produced, the quality direct influence zone product made from steel quality of scale removal effect.Roughing De-scaling box enters first time de-scaling before mill milling to rolled piece, is used for removing the once oxidation iron sheet that rolled piece produces in heating furnace.
The frequent produced problem of prior art is: the steel billet after heating furnace is fired is easy to the phenomenon occurring discount and nose, after steel billet head enters De-scaling box, often because steel billet head nose or discount, steel billet is caused to produce spring when working track is carried, jumping height is up to 300mm, steel billet head is caused to knock nozzle, cause nozzle head tungsten carbide high temperature failure, or cause nozzle to miscue because impact is excessive, knock, influence of rolled scale removal effect, occurs that iron sheet removes unclean phenomenon, causes nozzle exchange frequent.
In addition; the patent No. for " a kind of descaling spray nozzle protective device " disclosed in the patent document of CN201320691078 can play protection nozzle effect; but its structure is too complicated, cause the waste of steel, the too much cost of manufacture adding high pressure water descaling device.
Summary of the invention
The utility model provide a kind of have protection nozzle function water under high pressure header device, structure is simple, cost of manufacture is cheap, can effectively prevent from causing nozzle to be occurred by the phenomenon that damage is bad because of deformation of rolled wire, play the effect of protection hydraulic spray, can prolonging nozzle service life, reduce equipment breakdown, ensure belt steel product quality, improve the security of equipment simultaneously, reduce operation intensity, ensure high-pressure water descaling effect, extend water under high pressure collector life cycle, reduce spares reserve consumption costs, avoid the generation of great quality accident, strengthen lumber recovery.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of have protection nozzle function water under high pressure header device; comprise steel pipe, nozzle, guide plate, N number of nozzle is weldingly fixed on steel pipe, between an interval M nozzle, arrange guide plate; guide plate is weldingly fixed on steel pipe, and the length that guide plate stretches out from nozzle direction is longer than nozzle.
Compared with prior art, the beneficial effects of the utility model are:
A kind of have protection nozzle function water under high pressure header device; structure is simple; cost of manufacture is cheap; can effectively prevent from causing nozzle to be occurred by the phenomenon that damage is bad because of deformation of rolled wire; play the effect of protection hydraulic spray; can prolonging nozzle service life; reduce equipment breakdown, ensure belt steel product quality, improve the security of equipment simultaneously; reduce operation intensity; ensure high-pressure water descaling effect, extend water under high pressure collector life cycle, reduce spares reserve consumption costs; avoid the generation of great quality accident, strengthen lumber recovery.

In figure: 1. steel pipe .2. nozzle .3. guide plate .4. rolled piece.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is further illustrated:
As shown in Figure 1-2; the utility model is a kind of have protection nozzle function water under high pressure header device; comprise steel pipe 1, nozzle 2, guide plate 3; the individual nozzle 2 of N (N>1) is weldingly fixed on steel pipe 1; between the individual nozzle 2 of interval M (1≤M≤3), guide plate 3 is set; guide plate 3 is weldingly fixed on steel pipe 1, and the length that guide plate 3 stretches out from nozzle 2 direction is longer than nozzle 2.
See Fig. 2, nozzle 2 for high pressure nozzle be standard component, the connected mode between nozzle 2 and steel pipe 1 is: be directly welded on by the pedestal of nozzle 2 on steel pipe 1, and it is inner that the water inlet of nozzle 2 puts in steel pipe 1.
The wall thickness of steel pipe 1, should have can the intensity of anti-high pressure.
The suitable length that guide plate 3 exceeds nozzle 1 is 50mm.
After the utility model comes into operation, descaling header effect reaches desirable effect, has fairly obvious raising than before transformation, from beater plate test effect and actual removing iron sheet state, strike vestige is parallel, and point-blank, is 15 ± 5 DEG C with horizontal angle; The amount of lap of adjacent strike vestige, all at more than 7mm, meets the technological requirement of high-pressure water descaling completely.After the utility model uses, equipment failure rate is down to improved 8.3% by 25% before transforming, and equipment fault obviously declines, prolonging nozzle service life, reduce equipment breakdown, ensure belt steel product quality, improve the security of equipment simultaneously, reduce operation intensity, ensure high-pressure water descaling effect, extend water under high pressure collector life cycle, avoid the generation of great quality accident, strengthen lumber recovery.
