Abstract
The utility model discloses a roll barrel spray cooling device including a spraying tube which is arranged at one side in front of a roller so as to ensure that the spray direction and the tangent direction of a spray point of the external cycle of the roller form an included angle being 45 DEG to 50 DEG. By adjusting the spray angle of the spraying tube, the roll barrel spray cooling device of the utility model can ensure that the roller is evenly and fully cooled, avoid the condition that the thermal convexity of the roller is not good and a rolling piece has bad cooling effect due to the cooling problem, in addition, the cooling effect of the rolling piece is better due to the evenly and fully cooling, thereby the roll barrel spray cooling device can be applied to the high-speed steel rolling technology.
Description
Technical field
The utility model relates to a kind of steel rolling roll body of roll cooling device, particularly a kind of roll barrel spray cooling device.
Background technology
Medium plate mill's rolling mill roll cooling is a link important in the steel rolling process, if inhomogeneous, the local cooling condition not body of roll temperature of benefit raises, and causes local reaustenitizing, and cooling subsequently can be quenched to martensite, bainite again; These regional hardness risings, wearability are strengthened, in use wear and tear less and generation circle shape projection, the instant heating convexity is bad.In the prior art, rolling mill roll cooling generally adopts the mode of spraying cooling water to cool off, and cooling effect not only influences the hot convexity and the rolling template of roll, and cooling water also directly acts on the rolled piece, and the cooling velocity of rolled piece is had considerable influence.Existing cool water shower pipe biases toward roll cooling itself mostly, and best duty is that cooling water forms the thick and heavy moisture film of one deck attached to body surface, makes cooling evenly, fully; Avoid occurring the situation of iron scale in body of roll adhesion, avoided the generation of fatigue point, this is the most directly transient cause of top roll Apparently in Good Order﹠ Condition.If the angle of ejection cooling water and vertical direction is that α is too small, cooling water should not break through the diaphragm of roller surface, cools off insufficiently, if α is excessive, cooling water is beaten at roller surface and rebounded, and cooling effect is bad.Simultaneously, spraying cooling water can directly act on rolled piece, but the high speed steel rolling process needs the cooling velocity of rolled piece very fast, and chilling temperature is lower, and existing spray header is arranged and is not suitable for the high speed steel rolling process.Existing cooling structure is difficult to reach even cooling purpose, thereby the bad and bad situation of rolled piece cooling effect of roller heat convex degree learning occurs.
Therefore, need transform milling train body of roll cooling device, can guarantee to make roll evenly, fully cooling, avoid because the bad and bad situation of rolled piece cooling effect of the roller heat convex degree learning that the cooling problem occurs, and need cooling device can be applicable to the high speed steel rolling process.
The utility model content
In view of this, the purpose of this utility model provides a kind of roll barrel spray cooling device, can guarantee to make roll evenly, fully cooling, avoid because the bad and bad situation of rolled piece cooling effect of the roller heat convex degree learning that the cooling problem occurs, and can be applicable to the high speed steel rolling process.
For achieving the above object, a kind of roll barrel spray cooling device of the present utility model comprises shower, and described shower is arranged on roll and rolls last side, guarantees that the angle α of injection direction and roll cylindrical spray site tangential direction is 45 °-50 °.
Further, described roll comprises topping roll, and described topping roll top also is provided with two shower I, guarantees that the ejection waterline is perpendicular to topping roll;
Further, the current of described shower and shower I are regulated by the electrodeless control valve that is arranged on the pipeline;
Further, described shower guarantees that the angle α of injection direction and roll cylindrical tangential direction is 48 °.
The beneficial effects of the utility model are: roll barrel spray cooling device of the present utility model, adjust the spray angle of shower, can guarantee to make even, the fully cooling of roll, avoid because the bad and bad situation of rolled piece cooling effect of the roller heat convex degree learning that the cooling problem occurs, and because cooling is full and uniform, make the cooling effect of rolled piece better, applicable to telling steel rolling process; The top increases by two showers, increases cooling water inflow, and useful effect reduces the rolled piece temperature in rolled piece, more can be applicable to the high speed steel rolling process, and further increases all even abundant degree of roll cooling; The spray equipment water yield is adjustable, at different rolling mill practices, reconciles cooling water inflow flexibly.
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
Embodiment one
Accompanying drawing is a structural representation of the present utility model, as shown in the figure: roll barrel spray cooling device of the present utility model, comprise shower 1, shower 1 is arranged on topping roll 3 and rolls last side, guarantees that the angle α of injection direction and topping roll 3 cylindrical spray site tangential directions is 45 °.Topping roll 3 tops also are provided with two shower I2, guarantee that the ejection waterline is perpendicular to topping roll 3.The current of shower 1 and shower I2 are by being arranged on the step-less adjustment valve regulation on the pipeline.
Embodiment two
The difference of present embodiment and embodiment one is: shower 1 is arranged on topping roll 3 and rolls last side in the present embodiment, guarantees that the angle α of injection direction and topping roll 3 cylindrical spray site tangential directions is 48 °.
Embodiment three
The difference of present embodiment and embodiment one is: shower 1 is arranged on topping roll 3 and rolls last side in the present embodiment, guarantees that the angle α of injection direction and topping roll 3 cylindrical spray site tangential directions is 50 °.
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.
