Abstract
The utility model discloses a cooling water pipe structure for a roller. The cooling water pipe structure comprises a plurality of parallelly arranged cooling water pipes, wherein the cooling water pipes are in the shape of a circular arc; the two ends of each cooling water pipe adopt sealed structures; a plurality of nozzles are arranged on the inner sides of the cooling water pipes; a water inlet pipe is connected with the outer sides of the cooling water pipes; included angles are formed by the nozzles and the radial direction of a circular where the cooling water pipes are positioned; the inclining directions of the nozzles are the same; the cooling water pipes are mutually communicated through a plurality of connecting pipes. According to the cooling water pipe structure, the water spraying effects of the cooling water pipes can be more uniform, so that balanced cooling can be conducted on the roller better, and the service life of the roller is prolonged.
Description
Technical field
The utility model relates to a kind of cooling device, relates in particular to a kind of roll cooling water tubular construction.
Background technology
Roll is that steel rolling mill produces the important processing component of steel in hot rolling, during roll work, directly contacts and produce sliding friction with steel, so the temperature of roll generally can reach 1000～1200 ℃, so roll needs cooling in time when work.At present general method for adding a cooling water pipe above roll, along roller surface direction, vertically spray water, but water spray is less with the contact area of roller surface, make this method cooling effect poor, easily make roll occur crackle, fall the even phenomenon such as roll breakage of piece, and roll wear is accelerated, shorten service life, not only waste roll, also affect product quality.Simultaneously, existing cooling water pipe is all direct and main pipeline welds together, the water spray effect of sparge pipe is subject to the impact of main pipeline larger like this, when in main pipeline, hydraulic pressure is lower, easily cause the water pressure spraying from the nozzle of each cooling water pipe inconsistent, thereby easily cause cooling effect of roller unbalanced, easily the further damage of aggravation roll.
Utility model content
For prior art above shortcomings, the purpose of this utility model is just to provide a kind of roll cooling water tubular construction, the water spray effect that can effectively solve existing cooling water pipe is subject to the larger problem of impact of main pipeline, thereby make the water spray effect of each cooling water pipe more even, thereby breaker roll carries out equilibrium and cools better, to extend the service life of roll.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of roll cooling water tubular construction, is characterized in that: comprise several cooling water pipes that be arranged in parallel, described cooling water pipe is circular arc, and its two ends are enclosed construction; In the inner side of cooling water pipe, be provided with several nozzles, outside is connected with water inlet pipe; Described nozzle and cooling water pipe place circle radially between there is angle, and the incline direction of nozzle is also identical; Described cooling water pipe is interconnected by several tube connectors.
Further, the delivery port of described nozzle is flat structure, and the length direction of delivery port is consistent with the length direction of crossing water pipe.Can increase like this from the water of nozzle ejection and the contact area of roll, and the water between adjacent two cooling water pipes can mutually intersect or join to holding together, thereby make the roll integral body water that can be cooled carry out coolingly, make the cooling effect of roll better.
Further, the delivery port of described nozzle is wedge structure, and its bore away from cooling water pipe one end is greater than the bore near cooling water pipe one end.Can increase from the pressure of the water of nozzle ejection, thereby cooling effect is further increased.
Further, described tube connector is positioned at cooling water pipe middle part.Cooling water pressure force balance effect is better.
Compared with prior art, the utility model has the advantage of: simple in structure, easy to process; Can effectively improve the cooling effect of cooling water pipe, and cooling water pipe is communicated with by tube connector, make the water of cooling water pipe ejection be subject to the influence of hydraulic pressure of main pipeline less, thereby the effect that makes to spray water reaches unanimity, the equilibrium that is so more conducive to roll is cooling, to improve the service life of roll, and then improve the operating efficiency of milling train.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model;
Fig. 2 is side view of the present utility model.
In figure: 1-cooling water pipe, 2-nozzle, 3-water inlet pipe, 4-tube connector.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: referring to Fig. 1, Fig. 2, a kind of roll cooling water tubular construction, comprises several cooling water pipes that be arranged in parallel 1, and described cooling water pipe 1 is circular arc, and its two ends are enclosed construction; In the inner side of cooling water pipe 1, be provided with several nozzles 2, outside is connected with water inlet pipe 3; Described nozzle 2 and cooling water pipe 1 place circle radially between there is angle, and the incline direction of nozzle 2 is also identical; Described cooling water pipe 1 is interconnected by several tube connectors 4.During concrete enforcement, described tube connector 4 is positioned at cooling water pipe 1 middle part; Cooling water pressure force balance effect is better.
The delivery port of described nozzle 2 is flat structure, and the length direction of delivery port is consistent with the length direction of crossing water pipe; Can increase like this from the water of nozzle 2 ejection and the contact area of roll, and the water between adjacent two cooling water pipes 1 can mutually intersect or join to holding together, thereby make the roll integral body water that can be cooled carry out coolingly, make the cooling effect of roll better.
The delivery port of described nozzle 2 is wedge structure, and its bore away from cooling water pipe 1 one end is greater than the bore near cooling water pipe 1 one end; Can increase from the pressure of the water of nozzle 2 ejections, thereby cooling effect is further increased.
The utility model can effectively improve the cooling effect of cooling water pipe 1, and cooling water pipe 1 is communicated with by tube connector 4, make the water of cooling water pipe 1 ejection be subject to the influence of hydraulic pressure of main pipeline less, thereby the effect that makes to spray water reaches unanimity, the equilibrium that is so more conducive to roll is cooling, to improve the service life of roll, and then improve the operating efficiency of milling train.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or are equal to replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present utility model.
