Description
Technical field
The present invention relates to a kind of sparge pipe, more particularly to a kind of roll cooling sparge pipe.
Background technology
In hot rolling technology, roller temperature is too high to make roller quenching layer that tissue breakdown occurs, and roll surface additional answering is occurred
Power, and roll surface is produced cracking.Meanwhile, roller temperature is high also to be destroyed normal roll shape, make rolled products plate
Type is bad, and roller temperature is too high can also make lubricant failure, and causes that roll wear is accelerated, and service life shortens, not only
Roll is wasted, and increases cost, so must be cooled down to roll and temperature control.
Because the working surface distributed areas of the roll are different, then the surface temperature different zones temperature of the roll is caused
Degree is inconsistent, how both to have ensured adequately and reasonably cooling effect, realizes that the surface temperature of the roll is uniform as far as possible again, is industry
Technical problem urgently to be resolved hurrily.
In the prior art, the method for roll cooling is mainly directly increases setting water spray in the roller surface
Pipe, carries out realizing what is cooled by the direct spraying cooling water of sparge pipe to the roller surface.
But, the nozzle major part of existing sparge pipe is fixed, and its angle presets can not be changed.In actual production
During, roll may be changed according to production needs, and the pressure of coolant is likely to according to the wire rod processed
And adjusted the need for roll.If changing roll in production process or changing the pressure of coolant, the nozzle of fixed angle
Make the spray angle of coolant unadjustable, this can cause need to adjust position between whole cooling device and roll
Preferable cooling effect can be realized.This is clearly very cumbersome regulation process, increased the difficulty of adjustment and it is required when
Between.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of adjustable roll cooling sparge pipe of spray angle.
Central scope of the invention is：A kind of nozzle is installed on roll cooling sparge pipe, the nozzle includes flexibility
Short tube and nozzle head two parts, the flexible short tube realize that the spray angle of the nozzle head can adjust by bending.
The present invention provides a kind of roll cooling sparge pipe, including circular arc body and multigroup spray of the two ends in enclosed construction
Mouth, multigroup nozzle array is located at the center of circle side of the circular arc body and communicates therewith, and the nozzle includes flexible short tube
And nozzle head, one end of the flexible short tube and the circular arc body be interconnected, and the other end is connected with the nozzle head.
Preferably, the flexible short tube also includes changeover portion, and the changeover portion is located at the centre position of the flexible short tube,
It is the symmetrical structure that diameter is small at both ends and big in the middle, the length of the changeover portion is the 1/5~1/3 of the flexible short tube overall length, institute
It is circle to state the section of flexible short tube.Purpose is that, in order to required power is smaller when the flexible short tube bends, deformation concentrates on centre
It is a bit of without expanding to other positions, especially avoid outlet influence of the deformation to coolant flow beam.
Preferably, material is albronze, and the changeover portion is using annealing, in order to ensure that flexible short tube can
Its angle is able to maintain that to bend and after bending.
Preferably, the flexible short tube and circular arc body are threaded communication, and the flexible short tube one end perpendicular to
The surface of the circular arc body.
Preferably, the angle between every group of adjacent two nozzle of nozzle is identical, is 15~30 degree, in order to allow array
There is suitable spacing between the nozzle of setting.
Preferably, the roll cooling sparge pipe also includes connection short tube and multiple elbows, and the multiple elbow passes through
The connection short tube connection, and by the connection short tube and circular arc body vertical connection, the bending direction of adjacent double section belt arm
Conversely.
Preferably, the roll cooling sparge pipe also includes gradient tube, and the gradient tube is the multiple by what is connected
Elbow and connection short tube are connected with circular arc body, and the diameter of the gradient tube is gradually reduced towards the circular arc body direction.
The nozzle of the roll cooling sparge pipe provided compared to prior art, the present invention includes flexible flexibility
Short tube and nozzle head.Flexible flexible short tube causes that the spray angle of the nozzle head can adjust, therefore the roll is cooled down
Can neatly according to on-site actual situations precise control spray angle with sparge pipe.This can not only realize a fluid stream of coolant
Effect is narrowed, and cooling device can be made to meet the requirement of different rolls and wire rod to coolant spray angle, simplify cooling
The regulation process of device spray angle, reduces the regulation difficulty of spray angle.

Fig. 1 is referred to, is a kind of schematic diagram of preferred embodiment of roll cooling sparge pipe that the present invention is provided.It is described to roll
Roller cooling sparge pipe includes water inlet bend pipe 10, circular arc body 30 and multigroup nozzle 50.The water inlet bend pipe 10 includes gradual change
Pipe 11, multiple elbows 12 and connection short tube 13.
The gradient tube 11 is connected by the multiple elbow 12 and connection short tube 13 for connecting with circular arc body 30, and
Its diameter is gradually reduced towards the direction of circular arc body 30.
The multiple elbow 12 is connected by the connection short tube 13, and by the connection short tube 13 and circular arc body
30 connections, the bending direction of adjacent double section belt arm 12 is opposite.In the present embodiment, the water inlet bend pipe 10 includes two elbows 12.
The array of multigroup nozzle 50 is located at the center of circle side of the circular arc body 30 and communicates therewith, and multigroup spray
Mouth 50 and the water inlet bend pipe 10 are respectively positioned at the opposite side of the circular arc body 30.
As shown in Fig. 2 the nozzle 50 includes flexible short tube 51 and nozzle head 53.The section of the flexible short tube 51 is circle
Shape, it includes the first termination 511, the termination 513 of changeover portion 512 and second.First termination 511, the end of changeover portion 512 and second
First 513 are structure as a whole.First termination 511 is interconnected with the circular arc body 30, and the changeover portion 512 is located at institute
State between the first termination 511 and the second termination 513, second termination 513 is connected with the nozzle head 53.
The flexible short tube 51 is flexible flexible short tube, and its flexible enables the spray angle of nozzle head 53
Neatly according to on-site actual situations precise control, prevent unnecessary cooling water scattering problems.In order to ensure that flexible short tube can
It is able to maintain that its angle is constant to bend and after bending.Preferably, the material of the flexible short tube is albronze.
Preferably, first termination 511 and circular arc body 30 are threaded communication, and first termination 511 is vertical
With the surface of the circular arc body 30.
The symmetrical structure that the changeover portion 512 is small at both ends and big in the middle for diameter, its length is the overall length of the flexible short tube 51
1/5~1/3.Preferably, its length is the 1/3 of the overall length of the flexible short tube 51.The effect of the changeover portion 512 be make it is described
Required power is smaller when flexible short tube 51 bends, and deformation concentrates on middle a bit of without expanding to other positions, especially keeps away
Exempt from influence of the outlet deformation to coolant flow beam.The changeover portion 512 uses annealing, as long as disclosure satisfy that reduction hardness
And increasing the flexible requirement of the flexible short tube 51, the annealing process present invention used by it is not limited.
In the present embodiment, second termination 513 and nozzle head 53 are formed in one structure.It should be appreciated that being replaced at other
