Abstract
The utility model relates to a water spraying pipe for cooling of a roller. The water spraying pipe for cooling of the roller is used for cooling the roller. The water spraying pipe for cooling of the roller comprises a circular-arc-shaped pipe body, wherein the section of the pipe body is rectangular, nozzles are formed in one surface, close to the roller, of the pipe body, and an inclined angle between the direction of each nozzle and the direction of a tangent line of the corresponding roller is in a range of 0 degree to 35 degrees. The water spraying pipe for cooling of the roller is good in cooling effect, rollers are saved, and the quality of products is improved.
Description
Technical field
The utility model relates to a kind of roll cooling and uses sparge pipe, is used to cool off roll.
Background technology
Roll is steel rolling mill produces steel in hot rolling an important processing component, directly contact and produce sliding friction with steel during roll work, so the temperature of roll generally can reach 1000～1200 ℃, therefore roll needs cooling in time when work, at present general method is for adding a water pipe above roll, vertically spray water along the roller surface direction, but this method cooling effect is poor, make easily that roll hairline occurs, hardening cracks, quick-fried groove, lose flesh even the roll breakage phenomenon, not only waste roll, also influence product quality.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of roll cooling to use sparge pipe, good cooling results is saved roll, has improved product quality.
The utility model is that the technical scheme that its technical problem of solution is adopted is: described roll cooling sparge pipe, comprise that the cross section is the circular arc body of rectangle, body is provided with nozzle near the one side of roll, and the tangential direction angle of nozzle direction and the pairing roll of nozzle is 0 °～35 °.
Described nozzle throat area is wide at the top and narrow at the bottom, is divergent shape, and nozzle width is 1.5～3.5mm, and the nozzle of divergent shape has increased film-cooled heat.
Described nozzle evenly distributes for 15 °～20 ° with central angle on the circular arc body, and it is towards opposite with the roll rotation direction, and the time lengthening that water stops on roll has been strengthened cooling effect.
The beneficial effect that the utility model is compared with prior art had is:
1, the tangential direction of nozzle direction and the pairing roll of nozzle is 0 °～35 °, avoids nozzle vertically to spray water to roller surface, has improved cooling effect.
2, the nozzle throat area is wide at the top and narrow at the bottom, is divergent shape, and nozzle width is 1.5mm～3.5mm.The nozzle of divergent shape has increased film-cooled heat.
3, nozzle evenly distributes for 15 °～20 ° with central angle on the circular arc body, and it is towards opposite with the roll rotation direction.The time lengthening that water stops on roll has been strengthened cooling effect.
Description of drawings
Fig. 1 is the utility model embodiment schematic diagram;
Among the figure: 1, roll; 2, nozzle; 3, body; 4, support; 5, first angle; 6, second angle.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, roll cooling sparge pipe described in the utility model, comprise that the cross section is the circular arc body 3 of rectangle, body 3 is provided with nozzle 2 near the one side of rolls, and nozzle 2 is that first angle, 5, the first angles 5 are 15 ° to the angle with the tangential direction of the pairing roll 1 of nozzle, nozzle 2 towards with roll 1 direction of rotation, described nozzle 2 cross sections are wide at the top and narrow at the bottom, are divergent shape, and its width is 2.0mm; Angle between the adjacent nozzle 2 is that second angle, 6, the second angles 6 are 15 °.
During use, water filling in body 3, water is divergent shape and is injected on the roll 1, makes roll 1 cooling.
Claims (3)
1. a roll cools off and uses sparge pipe, comprise that the cross section is the circular arc body (3) of rectangle, it is characterized in that: body (3) is provided with nozzle (2) near the one side of roll (1), the tangential direction angle of nozzle (2) direction and the pairing roll of nozzle (2) (1) is first angle (5), and first angle (5) is 0 °～35 °.
2. sparge pipe is used in roll cooling according to claim 1, and it is characterized in that: described nozzle (2) cross section is wide at the top and narrow at the bottom, is divergent shape, and nozzle (2) width is 1.5mm～3.5mm.
3. sparge pipe use in roll according to claim 1 and 2 cooling, it is characterized in that: described nozzle (2) is gone up with 15 °～20 ° evenly distributions of central angle at circular arc body (3), its towards with roll (1) direction of rotation.
