Abstract
The utility model discloses a cooling device for rolling ring of high-speed wire rod mill, which comprises an arched water pipe concentrically arranged with a rolling ring, cooling water nozzles are juxtaposed on one side of the arched water pipe near the rolling ring, and facing towards the rotating direction of the rolling ring. The axis of the cooling water nozzles and the outer circle of the rolling ring intersect at an angle of 15 to 30 degree. In operation, cooling water sprays onto the groove of the rolling ring through the nozzles to cool down the rolling ring when the rolling ring rotates continuously, which effectively minimizes the possibility of fatigue damage of the rolling ring at a high temperature, lowers production cost and ensures a smooth operation.
Description
Technical field
The utility model relates to and is used for the finishing mill parts that high line is produced, particularly a kind of high line finishing mill collar cooling device.
Background technology
In the high-speed rod production process, the high temperature rolled piece passes through groove at a high speed, will produce higher temperature on the groove surface, thereby cause the collars temperature to raise, and collars will produce fatigue damage under complex conditions such as high temperature and alternate stress; Simultaneously, the groove generation certain deformation of also will expanding with heat and contract with cold has produced harmful effect to the quality of wire rod.For addressing the above problem, need to adopt cooling water pipe that collars is cooled off.
In the prior art, cooling water pipe is to be prepared by the common steel tube hot bending, the cooling water nozzle is welded on the in type water pipe after by the machine tooling moulding again, but this cooling water pipe has some deficiency: 1. adopt the method for welding to be difficult to guarantee that nozzle sprays the angle of cooling water, cooling water splashes seriously; 2. the water yield unreasonable distribution of nozzle; 3. the cooling water coverage rate is narrower; 4. the selection of water nozzle quantity is unreasonable, opening is big, hydraulic pressure is low, and cooling water can't be broken through at the formed air film in collars surface.Above shortcoming has caused the cooling effect of cooling water pipe not good, and the groove metal surface comes off seriously, and the collars surface color turns blue blue, the collars rapid wear, and it is apparent in view when rolling particularly to raise speed.
At above-mentioned deficiency, need existing cooling water pipe is improved, increase its cooling effect, be not damaged with the protection collars, ensure carrying out smoothly of producing.
The utility model content
In view of this, the utility model provides a kind of high line finishing mill collar cooling device, uses this water pipe can effectively improve the cooling effect of cooling water to collars, is damaged to prevent collars, ensures carrying out smoothly of producing.
High line finishing mill collar cooling device of the present utility model, comprise arc water pipe with the concentric setting of collars, described water pipe is set side by side with the cooling water nozzle near collars one side, the cooling water nozzle is met the direction of rotation to collars, its axis and collars cylindrical intersect, and the tangent line at intersection point place becomes 15～30 ° of angles on the axis of cooling water nozzle and the collars cylindrical.
Further, the rolled piece that the is positioned at collars flow that exports the cooling water nozzle of a side accounts for 30% of all nozzle flow summations;
Further, the quantity of described cooling water nozzle is 6;
Further, described water pipe is made by aluminium alloy.
The beneficial effect of utility model: high line finishing mill collar cooling device of the present utility model, comprise arc water pipe with the concentric setting of collars, described water pipe is set side by side with the cooling water nozzle near collars one side, the cooling water nozzle is met the direction of rotation to collars, its axis and collars cylindrical intersect, the tangent line at intersection point place becomes 15～30 ° of angles on the axis of cooling water nozzle and the collars cylindrical, during use, cooling water sprays in the groove of collars by nozzle, continue in the rotating process collars to be cooled off at collars, effectively reduce collars produces fatigue damage under hot conditions probability, thereby reduced production cost, guaranteed carrying out smoothly of production.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Accompanying drawing is a structural representation of the present utility model, as shown in the figure: the high line finishing mill collar cooling device of present embodiment, comprise arc water pipe 2 with collars 1 concentric setting, described water pipe 2 is set side by side with cooling water nozzle 3 near collars 1 one sides, cooling water nozzle 3 is met the direction of rotation to collars 1, its axis and collars 1 cylindrical intersect, when hydraulic pressure surpasses 0.5MPa, can destroy cooling water from the cooling water of cooling water nozzle ejection and run into formed steam blanket behind the red-hot collars, reach better cooling effect, can select the quantity of cooling water nozzle according to pressure of supply water, the pressure of cooling water adopts 0.5～1MPa to be advisable, under the too high situation of hydraulic pressure, can suitably increase the quantity of cooling water nozzle, otherwise then reduce its quantity, the tangent line at intersection point place becomes 15～30 ° of angles on the axis of cooling water nozzle 3 and collars 1 cylindrical, select for use suitable angle can prevent effectively that cooling water from splashing, improve cooling effect, present embodiment is selected 20 ° for use, during use, cooling water sprays to by nozzle in the groove of collars, continues in the rotating process at collars, collars is cooled off, effectively reduce collars produces fatigue damage under hot conditions probability.
In the present embodiment, the flow that the rolled piece that is positioned at collars 1 exports the cooling water nozzle of a side accounts for 30% of all cooling water nozzle flow summations, and the water yield of each water nozzle of reasonable distribution reaches best cooling effect.
In the present embodiment, described water pipe 1 is made by aluminium alloy, and weight was also lighter when intensity satisfied technological requirement, and is easy to use.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
