Abstract

The utility model discloses a spraying pipe used for roll body cooling, which comprises a water inlet, water outlets and a pipe body. The water outlets are a plurality of small holes arranged on the pipe body, the pipe body is set to be a T shape, and the water inlet is arranged at the middle part of the pipe body. The spraying pipe used for the roll body cooling can ensure the uniformity of pressure and the flow rate of the water outlets, cause a roll to be uniformly and fully cooled, and avoid the conditions of poor roll thermal degree of convexity and rolled piece cooling effect caused by the cooling problem.

Description

Roll barrel cooling shower

Technical field

The utility model relates to a kind of steel rolling roll body of roll cooling device, particularly a kind of roll barrel cooling shower.

Background technology

The 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.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.In the prior art, for reaching even cooling purpose, at the cooling water pipe pipe shaft a plurality of apertures are set, form shower, current spray from aperture, and cooling water pipe is parallel to the roll setting, reaches the purpose of the even cooling body of roll.In the prior art, water pipe is made L shaped more, as shown in Figure 1, ostium excurrens pressure foot, flow near water inlet are big, and reduce gradually away from the ostium excurrens pressure and the flow of import, therefore, because each apopore pressure and flow are inconsistent, be 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 the shower structure, 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.

The utility model content

In view of this, the purpose of this utility model provides a kind of roll barrel cooling shower, can guarantee to make the pressure of apopore and flow even, 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.

For achieving the above object, shower is used in a kind of roll barrel cooling of the present utility model, comprises water inlet, delivery port and pipe shaft, and described delivery port is a plurality of apertures that are arranged on the pipe shaft, and described pipe shaft is the setting of T font, and described water inlet is arranged on the pipe shaft middle part.

Further, described spray in-pipe flow is regulated by the electrodeless control valve that is arranged on water inlet.

The beneficial effects of the utility model are: roll barrel cooling shower of the present utility model, water inlet is arranged on the shower middle part, water inlet shunting both sides, can guarantee to make the pressure of apopore and flow even, 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; Current are adjustable, at different rolling mill practices, reconcile cooling water inflow flexibly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a prior art shower schematic diagram;

Fig. 2 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: shower is used in roll barrel cooling of the present utility model, comprises water inlet 1, delivery port 2 and pipe shaft 3, and delivery port 2 is for being arranged on a plurality of apertures on the pipe shaft 3, pipe shaft 3 is provided with for the T font, and water inlet 1 is arranged on the pipe shaft middle part.Shower water inlet 1 is provided with electrodeless control valve, and in-pipe flow is adjustable.

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.

Claims

1. a roll barrel cools off and uses shower, comprise water inlet (1), delivery port (2) and pipe shaft (3), described delivery port (2) is characterized in that for being arranged on a plurality of apertures on the pipe shaft (3): described pipe shaft (3) is provided with for the T font, and described water inlet (1) is arranged on the pipe shaft middle part.

2. shower is used in roll barrel cooling according to claim 1, it is characterized in that: described spray in-pipe flow is regulated by the electrodeless control valve that is arranged on water inlet (1).
