Description
Technical field
The invention belongs to hot-rolled sheet strip steel production technical field, is specifically related to one kind and is removed for hot-rolled sheet strip steel water under high pressure
Squama device.
Background technology
Hot-rolled sheet strip steel can occur to aoxidize and produce iron scale at high operating temperatures, if Strip can not be removed effectively
The iron scale on surface, and the Strip with iron scale is directly rolled, the abrasion of roll can be aggravated, reduction bites
Condition and Strip surface quality, therefore, removal scale on surface is needed to claim de-scaling before Strip enters roll.Mesh
Before, typically all use high-pressure water descaling.
Traditional high pressure water descaling device is to be arranged in juxtaposition upper and lower in Strip by a number of fan nozzle, and
With the angled purpose for carrying out jet impulse to steel plate, reaching de-scaling of belt steel surface.Have the drawback that：Adjacent fan-shaped spray
The water under high pressure that mouth jet goes out has certain lap in surface of steel plate, and optimal scale removal effect is can reach when lap is optimal；
When Strip thickness is by h0Increase to h1When, because nozzle height is constant, adjacent fan nozzle jet to water under high pressure during surface of steel plate
Lap reduces, and surface of steel plate de-scaling can be caused not thorough, iron scale strip occurs in surface of steel plate after de-scaling；Work as steel plate thickness
By h0It is down to h2When, the increase of water under high pressure lap, cause overlapping region jet impulse intensity too high, strip base steel may be damaged
Body, it is unfavorable for the raising of Strip surface quality.
The content of the invention
It is an object of the present invention to provide one kind to be used for hot-rolled sheet strip steel high pressure water descaling device, can be efficiently against prior art
The shortcomings that existing.
The present invention is achieved in that as shown in Fig. 1~2, it is characterized in that being installed successively on descaling device case lid 1.1
N-th water inlet pipe 2.1,2.2 ... that has first, second ..., 2.n, corresponding intake antrum is connected each water inlet pipe respectively；
Structure in the water cavity of connection corresponding with each water inlet pipe be stationarily connected to left and right horizontal dividing plate 1.5 among intracavitary and
1.6 will be divided into upper and lower two chambers and be formed in casing, spaced between left and right horizontal dividing plate 1.5 and 1.6, be fixedly connected on
There are first and the 3rd vertical partition plate 3.1,3.3 above left horizontal baffle 1.5, being fixedly connected on below case lid 1.1 has second
Epicoele is separated into the intake antrum IV being connected and by vertical partition plate 3.2, first, second, third vertical partition plate 3.1,3.2,3.3
First, second, third water storage water cavity I, II, III；Dividing plate 4 is fixedly mounted between left horizontal baffle 1.5 and bottom plate 1.3, by under
Chamber is separated into cavity VI and water chamber V, and the nozzle fixed plate 7 for being formed with arcwall face is arranged on water chamber V's by fixing screws 8
At lower right, the nozzle portable plate 6 for being formed with arcwall face is arranged on by adjusting screw 5 at water chamber V lower left, nozzle activity
Be formed as water spray seam 10 between plate 6 is corresponding with the arcwall face of nozzle fixed plate 7, water spray seam 10 is adjusted by adjusting screw 5
Size, the angle α between water spray seam 10 and steel plate 9 are 70 °.
The invention has the advantages that and good effect：
(1) descaling device casing delivery port is slit structure, after the current balance function of level Four damping structure, the wide side of plate
Injection uniformity is preferable upwards；
(2) lower surface of descaling device is planar structure, impact when can avoid Strip nose to nozzle, protects and removes
Squama device；
(3) descaling device delivery port jet direction and Strip operation opposite direction are in 70 ° of angles, and water under high pressure can be to iron oxide
Skin forms " backing-off cutting " effect, is advantageous to improve de-scaling efficiency.
