Abstract
A roller cooling device is fixed on a rolling-mill housing. the utility model comprises a fixed stander, a plurality of cooling pipes, and a plurality of nozzles, wherein the fixed stander is fixed on a beam of the rolling-mill housing; a plurality of cooling pipes are cambered, are fixed on the fixed stander respectively, correspond to a roller slot of a roller, and connect with a water pipe outside; a plurality of nozzles are respectively arranged on the cooling pipe; the arch length of the cooling pipe accounts for two fifths of the circumference of the whole roller; the mouth of the nozzle is flat, the injection angle Alpha is 65 to 80 degrees, and the nozzle integrates the cooling pipe. When being used, cooling water spurred by the nozzle covers the roller slot of the roller. The the utility model has the advantages that, with the roller being provided with the cooling pipe in an arch shape, and the roller being provided with the nozzle, the utility model guarantees that the roller can be cooled thoroughly and evenly.
Description
Technical field
The utility model relates to roll cooling device, particularly carbon tungsten roller ring.
Background technology
Carbon tungsten roller ring is used for rolled threaded steel and is different from general common roll, and it has advantages such as high rigidity, high abrasion, than common roll high life more than ten times.It is high that but the The field of carbon tungsten roller ring requires cooling water, not good as cooling effect, phenomenon such as be easy to generate the roll explosion, lose flesh.Existing roll cooling device just is provided with water injector in roll turnover guide and guard place, and the angle of water spray and area are all smaller, makes the roll cooling insufficient and inhomogeneous.
Summary of the invention
The purpose of this utility model is to design a kind of roll cooling device, can satisfy the collars cooling requirement, guarantees that the roll slotted eye obtains fully, cooling uniformly.
For achieving the above object, technical solution of the present utility model is:
Roll cooling device is fixed on the rolling-mill housing; Comprise fixed support, cooling water pipe, plurality of nozzles; Wherein, described fixed support is fixed on the crossbeam of rolling-mill housing; Described some cooling water pipes, curved, be individually fixed on the fixed support, corresponding to the groove on the roll, and external water pipe; Plurality of nozzles is arranged on the cooling water pipe respectively.
Further, described cooling water pipe arc length is 2/5 of a whole roll circumference.
Described nozzle spout is an offset flat shape;
The jet angle α of described nozzle spout is 65 °～80 °.
Described nozzle and cooling water pipe are integral structure.
Described nozzle number is 9.
Advantage of the present utility model is, because the curved cooling water pipe that is provided with of breaker roll is provided with nozzle and can guarantees that the roll slotted eye obtains fully, cooling uniformly on it.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model structure of nozzle schematic diagram.
The specific embodiment
As shown in Figure 1 and Figure 2, roll cooling device of the present utility model is fixed on the rolling-mill housing 5,5 '; Comprise fixed support 1,1 ', a plurality of cooling water pipe 2,2 ', plurality of nozzles 3,3 '; Wherein, described fixed support 1,1 ' is fixed on rolling-mill housing 5,5 ' the crossbeam; Described a plurality of cooling water pipe 2,2 ' is curved, is individually fixed in fixed support 1,1 ', and corresponding to the groove on the roll 4,4 ', cooling water pipe 2,2 ' external water pipe; Nozzle number on the described single cooling water pipe 2 is 9, is arranged at respectively on the cooling water pipe 2; Described cooling water pipe 2,2 ' arc length are 2/5 of whole roll 4,4 ' circumference; Nozzle 3,3 ' and cooling water pipe 2,2 ' be integral structure; Nozzle 3 spouts 31 are offset flat shape, and the jet angle α of nozzle 3 spray chambers 32 is 70 °.
Cooling water pipe 2,2 ' camber can guarantee that whole roll 4,4 ' circumference have 2/5 part to obtain cooling, and the jet angle α of nozzle 3 spray chambers 32 is 70 °, and during use, the cooling water cocoa that nozzle 3 sprays covers roll 4,4 ' groove.
By implementing the utility model, roll records the body surface temperature behind continuously hot rolling be 42 ℃, satisfies the requirement of body of roll temperature≤50 ℃ fully.Reach 3200 tons through rolling φ 20mm screw-thread steel list groove, after pulling down, the groove wearing and tearing are even, and Apparently in Good Order﹠ Condition is the rolling higher tonnage of ability after obtaining sufficient water cooling thereby can draw roll, and improved 15 times than former roll service life.
