Description

[0001] Spraying apparatus and high temperature material cooling apparatus using same [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injection apparatus and a high temperature material cooling apparatus including the same, and more particularly, to an injection apparatus capable of uniformly cooling a high temperature material and a high temperature material cooling apparatus including the same.

In general, the continuous casting facility is for producing molten steel as a semi-finished product such as cast steel, and is composed of a tundish, a mold and a plurality of castor rolls. After molten steel passes through the mold to form a solidified layer, And a manufacturing process of cooling the surface of the cast steel by injecting cooling water when passed between a plurality of castor rolls.

Thus, the casting of the continuous casting equipment is cut to a certain size in the torch cutting machine, and then the work is repeatedly carried out for each of the plurality of lines by the correction line conveying roller table. Thereafter, when the finished product is transported to the post-process or the removal of the surface defect is required for each of the respective routes, that is, the product to be hand scaped is placed on the casting cooling bed. At this time, when the scraps to be hand scalled are cooled after about 24 hours, they are transferred to a hand scaping field by a tong crane and scoured to a hand torch, Perform a correction operation to cut with a cutting machine. Correction work must be done with sufficient cooling of the casting since the work is carried out on the casting.

Therefore, the casting is cooled by injecting a fluid such as cooling water to the casting placed on the casting cooling bed using a cooling device. However, the conventional cooling device is configured to be able to jet the fluid in a predetermined direction, for example, in the horizontal direction, and cooling of the cast steel that is placed within a certain range is possible. That is, since the conventional cooling device is configured to inject the fluid in the horizontal direction, it is difficult to control the jetting distance of the fluid, so that it is difficult to cool the cast product located at a distance or at a distance from the cooling device. Therefore, it is difficult to uniformly cool the cast steel, so that the operator is liable to be exposed to the high temperature cast steel during the correcting operation, and the hose for supplying the fuel to the hand torch can be connected to the operation accident in which the fuel is leaked.

The second stopper 168 may be used to prevent the body 120 from rotating in the left-right direction when the streak 134 is rotated in the up-and-down direction through the first rotating member 140.

With this configuration, the injector according to the embodiment of the present invention can independently rotate the body 120 and the jetting unit 130 so that the jetting direction of the fluid jetted through the jetting line 134 can be freely moved up, down, Can be adjusted. Particularly, since the spraying distance of the fluid injected through the streaks 134 can be adjusted by moving the streaks 134 in the vertical direction, it is possible to uniformly cool the high-temperature processed material, for example, high-temperature stakes. Therefore, the worker can perform the work in a safe environment, thereby reducing the burden on the worker. It is also possible to prevent the occurrence of safety accidents due to fuel leakage or the like by preventing the welding loss of the pipe supplying the fuel to the hand torch.
