Fig. 2 is a perspective view showing the material cooling apparatus shown in Fig. 1 in an exploded state.
FIG. 3 is a perspective view showing a state where a material to be transferred to the material cooling apparatus shown in FIG. 1 is applied.
4 is a perspective view showing a state in which the workpiece cooling apparatus shown in FIG. 1 is operated in accordance with the width of a workpiece.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 is a perspective view showing a material cooling apparatus 100 according to a preferred embodiment of the present invention, FIG. 2 is a perspective view showing the material cooling apparatus 100 shown in FIG. 1 in an exploded state, FIG. 4 is a perspective view showing a state in which the workpiece cooling apparatus 100 shown in FIG. 1 is operated in accordance with the width of the workpiece S, As shown in Fig.

1 to 4, a workpiece cooling apparatus 100 according to a preferred embodiment of the present invention includes a jetting section 101, a blocking section 102, and guide sections 103, (S) conveyed by the conveying rolls (10) along the conveying path (F). Also, in this embodiment, the workpiece S is in the form of a plate having a predetermined thickness such as a slab, a steel plate, a thick plate, or the like.

The jetting section 101 is positioned between the conveying rolls 10 and located above and below the workpiece S to be conveyed along the conveying direction F. [ Further, the jetting section 101 is positioned along the width direction W of the material S to be conveyed. At this time, the sprayer 101 cools the material S by spraying cooling water toward the material S conveyed along the conveying direction F. Here, the width direction W of the work S is a direction corresponding to the longitudinal direction of the feed roll 10 orthogonal to the feed direction F of the work S as shown in Fig. The jetting section 101 includes a head section 111 and a nozzle section 113.

The head portion 111 is located above and below the work P to be conveyed along the width direction W of the work S to be conveyed. Further, cooling water is supplied to the inside of the head portion 111. [

The nozzle portions 113 are formed in the head portion 111 so as to face the material S to be transported. The cooling water is injected in the vertical direction toward the work (S) through the nozzle parts (113) while being stored in the head part (111). As the cooling water is injected into the material S, the material S is cooled. In the present embodiment, the nozzle units 113 are disclosed in the form of an opening formed in a recessed portion in the head unit 111, but may be opened in the form of protrusions protruding from the head unit 111 in the state where the openings are formed.

The blocking portions 102 are located at the end portions of the spraying portions 101, respectively, and are movable along the spraying portions 101. At this time, the blocking portions 102 move along the width direction W of the work S to adjust the gap and cover the jetting portion 101. That is, a part of the spraying portion 101 is blocked by being covered by the blocking portions 102, so that the cooling water can not be sprayed toward the material S and the spraying portion 101 (not covered by the blocking portions 102) ) Is not blocked so that the cooling water is sprayed. Here, the remaining part of the jetting section 101 means the jetting section 101 located between the blocking sections 102. [ At this time, the area of the jetting portion 101 covered by the blocking portions 102 is changed. The blocking portion 102 includes a slide portion 121 and a slide driving portion 123.

The slide portion 121 has an insertion space portion 102a. The insertion space portion 102a is formed at one end of the slide portion 121 and the end portion of the injection portion 101 is inserted into the insertion space portion 102a. Further, the slide portion 121 moves along the jetting portion 101 to cover the jetting portion 101. At this time, the slide portion 121 seals the jetting portion 101, particularly the nozzle portions 113. Therefore, the spray portion 101 covered by the slide portion 121 can not spray the cooling water through the nozzle portions 113. The movement of the slide part 121 selectively determines the nozzle parts 113 in which the cooling water is injected in the spray part 101 and changes the number of the nozzle parts 113 covered on the slide part 121 . As a result, as shown in Fig. 4, the cooling water can be injected in accordance with the width of the material S.

The slide driver 123 is connected to the end of the slide member 121 to move the slide member 121. The slide driving unit 123 includes a guide bar 123a, a driving body 123b, and a connecting bar 123c.

The guide bar 123a passes through the end of the sorting part of the slide part 121 and is connected to the jetting part 101, particularly to the head part 111. [

The driving body portion 123b is connected to the end of the sorting portion of the slide portion 121 to move the slide portion 121 along the guide bar 123a. Meanwhile, the driving body portion 123b of the present embodiment is formed in the shape of a cylinder or the like, and the length thereof is changed to move the slide portion 121.

The connecting bar 123c connects the guide bar 123a and the driving body 123b. Thus, the driving body portion 123b moves the slide portion 121 along the guide bar 123a in a fixed state.

The guide portions 103 extend from the blocking portion 102 in the vertical direction toward the conveying rolls 10, respectively. That is, the guide portions 103 extend toward the work S conveyed from the lower side of the blocking portion 102. The guide portions 103 are spaced apart from each other such that the guide portions 103 are aligned with the width of the work S by the blocking portions 102. The cooling water is injected from the spraying portion 101 not covered by the blocking portions 102 so as to correspond to the direction of the arrow shown in Fig. 4 and flows between the guide portions 103 and along the guide portions 103 . The guide portion 103 includes a main guide portion 131 and an auxiliary guide portion 133.

The main guide portion 131 is in the form of a plate and is positioned adjacent to the blocking portion 102, particularly the material S to be conveyed, particularly the upper surface, perpendicular to the slide portion 121.

The auxiliary guide portions 133 extend from both sides of the main guide portion 131 and are parallel to each other. The cooling water injected from the jetting section 101 flows between the main guide sections 131 and flows into the auxiliary guide sections 133. Therefore, the auxiliary guide portions 133 can combine with the main guide portion 131 to guide the cooling water jetted from the jetting portion 101 to the material S stably, thereby remarkably reducing the scattering of the cooling water.

Therefore, as the distance between the guide portions 103 is positioned in accordance with the width of the material S, the cooling water may not reach both sides of the material S by the guide portions 103. As a result, both side portions of the work S are prevented from being undercooled, and the deviation of the work S along the width direction of the work S can be controlled to some extent.

Although the blocking portions 102 and the guide portions 103 are illustrated as being applied only to the jetting portion 101 located on the upper side of the material S in the present embodiment, Or may be applied to both of the spraying portions 101 located above and below the work S.

In the case where the blocking portions 102 and the guide portions 103 are located in the jetting portion 101 positioned on the upper side of the work S as shown in this embodiment, (100) may further include auxiliary blocking portions (104).

The auxiliary blocking portions 104 are installed in the guide portion 103 so as to face the blocking portions 102, respectively. At this time, the auxiliary blocking portions 104 are positioned adjacent to the jetting portion 101 positioned below the material S to be transported. Further, the auxiliary blocking portion 104 is connected to the blocking portion 102 by the guide portion 103. As a result, when the blocking portion 102 moves, the auxiliary blocking portion 104 also moves in the same direction. That is, the auxiliary blocking portion 104 may also be moved and aligned with the width of the work S.

On the other hand, the auxiliary blocking portions 104 cut off part of the cooling water injected from the jetting portion 101 located below the material S to be conveyed. At this time, the auxiliary cut-off portions 104 are formed in a state in which the cooling water jetted from the jetting portion 101 located below the workpiece S fed in combination with the guide portions 103 is sprayed, It is possible to prevent reaching the upper surface. In addition, blocking grooves (not shown) are formed on the lower surfaces of the auxiliary blocking portions 104 so that the prevention of splashing of the cooling water by the auxiliary blocking portions 104 due to the blocking groove can be improved. Here, the lower surface of the auxiliary blocking portions 104 is a surface facing the jetting portion 101 positioned below the material S to be transported.

Therefore, the workpiece cooling apparatus 100 according to the present embodiment allows the cooling water to be sprayed onto the workpiece S in accordance with the width of the workpiece S. Thus, the cooling water is sprayed to the material S stably along the width direction W of the material S to cool the material S. At this time, unnecessary cooling water reaches the material (S) or remains in the material (S), and the supercooling of the material (S) can be prevented. Therefore, the material cooling apparatus 100 according to the present embodiment can reduce the temperature deviation along the width direction W of the work S, thereby stably maintaining the quality of the work S.

While the present invention has been described in connection with certain exemplary embodiments, it will be understood by those skilled in the art that various changes may be made without departing from the scope of the present invention.
