Description

Skid device {SKID APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skid device, and more particularly, to a skid device that supports materials in a heating furnace while preventing accumulation of scale and minimizing heat transfer to a material.

Generally, materials produced through a performance process such as a slab or billet are heat treated prior to rolling. The heat treatment of the material is performed inside the heating furnace. A skid pipe for moving the material is installed inside the heating furnace. Cooling water flows into the inside of the skid pipe, and an insulator is installed on the inner circumferential surface of the skid pipe. On the other hand, a skid button for supporting the material is provided on the skid pipe. The skid button is for forming a space on the lower surface of the material so that the upper and lower portions of the material can be uniformly heated. However, since the amount of heat that flows into the lower surface of the material through the space formed by the skid button is small, a temperature deviation occurs in the material, and a skid mark is formed on the lower surface of the material. Particularly, since the skid button is cooled by the cooling water circulated in the skid pipe, the temperature is lower than the temperature inside the heating furnace, so that a skid mark is generated on the lower surface of the material.

Also, the high-temperature scale removed from the bottom surface of the heated material is deposited to cover the entire upper surface of the skid pipe. At this time, if the height of the deposited high-temperature scale is increased to be higher than the height of the skid button, the high-temperature scale has a component similar to that of the material and may react with the surface of the material to cause surface defects.

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 skid device 100 according to a first preferred embodiment of the present invention, FIG. 2 is a perspective view illustrating the skid device 100 shown in FIG. 1 in an exploded manner, Fig. 3 is a side view showing the skid device 100 shown in Fig.

1 to 3, a skid device 100 according to a first preferred embodiment of the present invention includes a main pipe portion 101, button portions 102 and guide portions 103, And can be used to move the work S in a supported state inside a heating furnace (not shown).

The main pipe portion 101 is positioned below the work S. The main pipe portion 101 is formed with a flow hole 101a. The flow hole 101a is formed along the longitudinal direction of the main pipe portion 101, and the cooling water flows in. The cooling water flows along the longitudinal direction of the main pipe portion 101 in the flow hole 101a to prevent deformation of the main pipe portion 101 due to the internal heat of the heating furnace.

On the other hand, coupling grooves 101b are formed on the upper portion of the main pipe portion 101. [ The coupling groove 101b is used for coupling the main pipe portion 101 and the button portion 102. [ Further, the main pipe portions 101 are formed of at least a pair and are positioned parallel to each other.

The main pipe portion 101 is not limited to being located below the material S as described above. The main pipe portion 101 may be provided on the bottom side in a facility such as a heating furnace, And the like.

The button portions 102 are located above the main pipe portion 101 and support the lower surface of the work S. At this time, the button portions 102 are positioned along the longitudinal direction of the main pipe portion 101. On the other hand, each of the button portions 102 has a blocking hole 102a. The blocking hole 102a is formed along the longitudinal direction of the main pipe portion 101. However, the blocking hole 102a is not limited to this and may be formed in various directions in the button portion 102, for example, May be formed along the width direction.

In addition, air flows in the blocking hole 102a. As a result, heat exchange between the workpiece S and the main pipe portion 101 through the button portion 102 is restricted. As a result, the temperature of the main pipe portion 101 can be restricted from affecting the work S. Accordingly, the temperature deviation is reduced on the lower surface of the material S generated by the button portion 102, and skid marks can be prevented from being formed on the material S.

The engaging portion 121 is formed below the button portion 102. The engaging portion 121 is inserted into the engaging groove 101b. At this time, the engaging portion 121 has a larger cross-section than the button portion 102 and has a size corresponding to the engaging groove 101b. As a result, the button portion 102 is positioned at the upper portion of the main pipe portion 101. The button portion 102 is coupled to the main pipe portion 101 or detachable from the main pipe portion 101. [ As a result, even if the button portion 102 is damaged due to contact with the work S, the button portion 102 becomes easily replaceable. It is also possible to confirm the state of engagement between the main pipe portion 101 and the button portion 102 according to the degree of insertion of the coupling portion 121 into the coupling groove 101b.

The button portions 102 are located at the upper portion of the main pipe portion 101 in a zigzag shape along the longitudinal direction of the main pipe portion 101. As a result, the workpiece S supported by the button portions 102 can be stably positioned on the button portions 102.

The guide portions 103 extend from the side surface of the button portion 102 and are inclined toward the main pipe portion 101, respectively. At this time, the guide portions 103 are formed in a plate shape and are positioned on the upper side of the main pipe portion 101 to cover the main pipe portion 101.

Further, the guide portion 103 has an induction angle? Of at least 45 degrees. Here, the induction angle? Refers to an acute angle formed between the vertical surface of the button portion 102 and the upper surface of the guide portion 103. As a result, the scale dropped from the work S is guided to the upper surface of the guide portion 103 smoothly and descends along the guide portion 103. [ On the other hand, it is preferable that the induction angle alpha is set so that the scale guided on the upper surface of the guide portion 103 is smoothly guided and the descending scale does not reach the main pipe portion 101, desirable. Therefore, surface defects of the workpiece S due to contact of the scale with the workpiece S accumulated on the skid device 100 can be prevented.

On the other hand, the upper end portion of the guide portion 103 is positioned above the blocking hole 102a. As a result, the scale guided to the upper surface of the guide portion 103 is not scattered by the air in the blocking hole 102a.

FIG. 4 is a perspective view showing a skid device 200 according to a second preferred embodiment of the present invention, FIG. 5 is a perspective view of the skid device 200 shown in FIG. 4, Fig. 3 is a side view showing the skid device 200 shown in Fig.

4 to 6, the skid device 200 according to the second preferred embodiment of the present invention includes the main pipe portion 101, the button portions 202, And a guide portion 203, and can be used to move the work S in a supported state inside a heating furnace (not shown). However, the present embodiment has the guide portion 203 different from the first embodiment, and accordingly, the button portion 202 also differs. The present embodiment will be described focusing on the above differences.

The guide portion 203 is formed in a plate shape and is inclined toward the main pipe portion 201 with respect to the button portions 202. At this time, guide holes 203a are formed in the guide portion 203 so as to correspond to the button portions 202. At this time, the guide hole 203a has a shape corresponding to the cross section of the button portion 202. [ The button portion 202 is inserted into the guide hole 203a and the upper surface of the button portion 202 is positioned above the guide portion 203. [ Thus, the upper surface of the button portion 202 is brought into contact with the lower surface of the work S, and the work S is supported by the button portion 202. Further, the guide portion 203 covers the main pipe portion 201. Particularly, the guide portion 203 covers not only the main pipe portion 201 corresponding to the button portion 202 but also the main pipe portion 201 between the button portions 202.

Further, the guide portion 203 has an induction angle? Of at least 45 degrees. Here, the induction angle? Refers to an acute angle formed between a vertical surface to the side surface of the button portion 202 and the upper surface of the guide portion 203. As a result, the scale dropped from the workpiece S is smoothly guided to the upper surface of the guide portion 203 and descends along the guide portion 203. On the other hand, it is preferable that the induction angle alpha is set so that the scale guided on the upper surface of the guide portion 203 is smoothly guided and the descending scale does not reach the main pipe portion 201, desirable. Therefore, surface defects of the workpiece S due to contact of the scale with the workpiece S accumulated on the skid device 200 can be prevented.

On the other hand, a stopper portion 223 protrudes from the side surface of the button portion 202. The button portion 202 is inserted into the guide hole 203a until the lower surface of the guide portion 203 comes into contact with the stopper portion 223. At this time, the guide part 203 covers the main pipe part 201 in a state of being separated from the main pipe part 201.

At this time, a blocking hole 202a is formed in each of the button portions 202. [ The blocking hole 202a is formed on the lower side of the stopper portion 223 along the width direction of the main pipe portion 201. The present invention is not limited to this, And may be formed along the longitudinal direction of the main pipe unit 201.

Further, air flows in the blocking hole 202a. As a result, heat exchange between the workpiece S and the main pipe portion 201 through the button portion 202 is restricted. As a result, the temperature of the main pipe portion 201 can be restricted from affecting the material S. Therefore, the temperature deviation is reduced on the lower surface of the material S generated by the button portion 202, and skid marks can be prevented from being formed on the material S.

As described above, the skid devices 100 and 200 according to the present invention can prevent the cooling water flowing into the main pipe portions 101 and 201 from flowing into the blocking holes 102a and 202a of the button portions 102 and 202, It is possible to prevent the skid marks from being formed at the contact portion between the material S and the button portions 102 and 202 and to prevent the skid marks from being formed at the contact portions between the scales Is not accumulated.

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.
