Description
Technical field
The utility model is related to a kind of smooth liquid jetting devices for cold rolled strip steel production.
Background technology
Cold-strip steel need to spray leveling precision when smooth to strip and work roll surface, it is desirable that be ejected into the flat of belt steel surface
Whole liquid is uniform, and leveling precision cannot recycle, and it is 930-1250mm, leveling precision spray that eight steel cold rollings produce width specifications range at present
It is 1300mm to penetrate width range, when producing the strip of 1000mm or so width, smooth liquid jetting device upper and lower ends 150mm models
The leveling precision for enclosing injection does not have utilization upper, is expelled directly out.The steel plate of different in width uses the emitted dose of maximum width, can not achieve
According to the width adjustment leveling precision spray regime of production steel plate, leveling precision waste is big；One ton 13000 yuan of leveling precision at present, ton steel
Leveling precision consumption is in 0.7Kg/t or more, and domestic and international leveling precision consumption is in 0.4Kg/t or less.In addition, leveling precision discharge rate increases,
Increase cost for wastewater treatment.
Invention content
The purpose of this utility model is to provide a kind of smooth liquid jetting devices for cold rolled strip steel production, are ensureing to spray
Be mapped to belt steel surface leveling precision it is uniform under the premise of, can reduce leveling precision consumption, reduce enterprise's production cost.
The purpose of this utility model is achieved in that a kind of smooth liquid jetting device for cold rolled strip steel production, packet
The two horizontally disposed leveling precision transfer pipelines for including upper and lower part fixed beam and being respectively communicated in the fixed beam,
Uniformly nozzle is arranged in interval on leveling precision transfer pipeline, and the internal diameter of leveling precision transfer pipeline middle part tube body is conveyed more than leveling precision
The tube body outboard end of the internal diameter of tube body at pipeline both ends, leveling precision transfer pipeline both ends is connected with the fixed beam both ends respectively
Logical, tube two sides are separated by by flange baffle and the tube body at leveling precision transfer pipeline both ends respectively in the middle part of leveling precision transfer pipeline
Absolutely, be connected to independent inlet tube in the middle part of leveling precision transfer pipeline on tube body, the tube body at the leveling precision transfer pipeline both ends it
Between be connected by bypass pipe.
The utility model ensure be ejected into belt steel surface leveling precision it is uniform under the premise of, realize 1100mm（Contain
1100mm）The above width specifications use the injection of maximum width, 1100mm or less width specifications to use the injection of 1100mm width.
Width is produced more than or equal to before 1100mm strips, the entire active length of leveling precision transfer pipeline is opened, is sprayed；Production is wide
Before degree is less than 1100mm strips, the independent inlet tube on the middle part tube body is only opened, is sprayed by middle part tube body, is put down
The tube body of whole liquid transfer pipeline both sides can reduce leveling precision consumption 15% or so in this way without spraying operation, leveling precision ton
Steel consumption is reduced to 0.5Kg or less.
Description of the drawings
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the main structure diagram of the utility model；
Fig. 2 is the main structure diagram of the utility model leveling precision injection line.
Specific implementation mode
A kind of smooth liquid jetting device for cold rolled strip steel production as shown in Figure 1, 2, including is mounted on planisher memorial archway
The outlet tension roll assembly 1 and entrance tension roll assembly 2 of 5 both sides pass through strip 10 between two roller groups, are located at planisher memorial archway 5
Interior upper backup roll 4, top working roll 6 and bottom working roll, lower backing roll are clamped strip, are conveyed, leveling precision injection dress
It sets on the planisher memorial archway 5 that 3 are mounted between top working roll 6 and entrance tension roll assembly 2.Smooth liquid jetting device 3 includes upper and lower
Portion's fixed beam 7,12 and two horizontally disposed leveling precision transfer pipelines being respectively communicated in the fixed beam, it is smooth
Uniformly nozzle 11 is arranged in interval on liquid transfer pipeline, and the internal diameter of leveling precision transfer pipeline middle part tube body is more than leveling precision delivery pipe
The tube body outboard end of the internal diameter of tube body at road both ends, leveling precision transfer pipeline both ends is connected with the fixed beam both ends respectively,
Tube two sides are isolated by flange baffle and the tube body at leveling precision transfer pipeline both ends respectively in the middle part of leveling precision transfer pipeline, are put down
Independent inlet tube 9,14 is connected in the middle part of whole liquid transfer pipeline on tube body, between the tube body at the leveling precision transfer pipeline both ends
It is connected by bypass pipe 8,13.
In use, leveling precision is respectively enterd by upper and lower part fixed beam 7,12 on the outside of leveling precision transfer pipeline flange baffle
Tube body in, width is sprayed more than the band steel edge of 1100mm；It is less than the strip of 1100mm for width, in closing,
Leveling precision channel in lower part fixed beam 7,12；Leveling precision only needs to enter tube body in the middle part of leveling precision by independent inlet tube 9,14
It is sprayed.Whole leveling precision transfer pipeline can in due course be worked according to the width of strip in this way, to play section
Save the effect of leveling precision dosage.
