Description

  The present invention relates to a drainer for removing cooling water adhering to a rolling roll.

  When manufacturing a steel product, a steel slab (slab), which is a semi-finished product, is first manufactured by continuous casting, and the manufactured steel slab is processed into a predetermined shape through a rolling process or the like. In the rolling process, the steel slab is rolled by a rolling roll and formed into a strip-shaped steel (hot coil). Moreover, especially when performing the hot rolling which rolls in the state which made the material high temperature, since a rolling roll also becomes high temperature, a cooling system which supplies a cooling water to a rolling roll is needed for a rolling installation. However, since the cooling water may adversely affect the steel slab, a draining device for removing the cooling water adhering to the rolling roll is indispensable in the cooling system. A wiper method is generally adopted for this drainer. The wiper-type draining device includes a blade having a rubber member disposed at the tip, and the cooling water is removed by pressing the blade against the surface of the rolling roll to wipe the surface of the rolling roll.

  On the other hand, when a part of a steel slab adheres to the surface of the rolling roll, if the surface is distorted by polishing of the surface to remove the attached steel slab, a draining device for the axis of the rolling roll for some other reason. In many cases, such as when the blades are not parallel, the rolling roll itself or the surface is deformed in the course of use. However, the original draining device had a structure in which the blade was moved in parallel and pressed against the surface of the rolling roll as it was, so that when the surface of the rolling roll was deformed, such as distortion or inclination, the blade was in close contact with the surface of the rolling roll. In other words, the cooling water may not be sufficiently drained, and the rubber member may be worn away.

  On the other hand, a draining device has been proposed in which an inflatable bag (tube) is arranged behind the blade and air is supplied and exhausted to adjust the inclination of the blade with respect to the axis of the rolling roll. (See Patent Document 1). According to such a configuration, even if the surface of the rolling roll is deformed, the blade can be brought into close contact with the surface of the rolling roll, so that water can be sufficiently drained and uneven wear of the rubber member can be suppressed. it can.

  However, the above draining device provided with a bag body requires equipment such as an air pressure source and air piping for supplying air to the bag body, and there has been a tendency for manufacturing cost and operation cost to increase. Further, due to the problem of the expansion rate of the bag body, the amount of displacement of the blade that can be controlled is small. In fact, there are cases where a plurality of bag bodies are stacked and used, resulting in a complicated structure.

  The present invention has been made in order to solve the above-described problems, and is a rolling roll draining device capable of draining appropriately even if the rolling roll is deformed while having a simple structure so as to reduce costs. It is intended to provide.

  The present invention has been made to solve the above-described problems, and a draining device according to the present invention is a draining device that removes cooling water adhering to the surface of a rolling roll. A movable base material extending substantially in parallel to the movable base member, a rubber member attached to an edge of the movable base material on the rolling roll side, and holding the movable base material so as to be able to advance and retreat in the direction of the rolling roll. A holding member and a plurality of urging members for urging the movable base toward the rolling roll, wherein the plurality of urging members are continuously disposed along the movable base, Independently, the movable substrate is urged toward the rolling roll.

  According to this configuration, since the plurality of urging members independently urge the movable base, it is possible to prevent a force from being biased to a part of the movable base (rubber member). Therefore, the rubber member as a whole can be brought into close contact with the rolling roll for appropriate drainage, and uneven wear of the rubber member can be suppressed. In addition to this, according to the above-described configuration, since the urging member having a simple structure can be used, facilities such as an air source are not necessarily required, and the manufacturing cost and operation cost of the draining device are not necessarily required. Can be suppressed.

  In the draining device, the urging member may be a leaf spring formed in an annular shape. According to such a configuration, it is not necessary to positively control the urging member, and since the structure is simple compared to a coil spring or the like, dust does not accumulate and maintenance can be easily performed.

  In the above draining device, the movable base material may be composed of a plurality of independent partial base materials, and the biasing member may bias the partial base material toward the rolling roll. According to this structure, since each partial base material moves independently, the responsiveness with respect to a deformation | transformation of a rolling roll can be improved.

  ADVANTAGE OF THE INVENTION According to this invention, although it is a simple structure, even if a rolling roll deform | transforms, the draining device of the rolling roll which can drain water appropriately can be provided.

Can rotate to the center. Other members such as the holding member 2 are placed on the side of the rolling roll R (hereinafter referred to as “front side”) of the draining device main body 1, and a weight 8 is attached to the side opposite to the rolling roll R. Therefore, when the load of the weight 8 is converted into a force in the rotation direction and the draining device body 1 rotates (rotates clockwise in FIG. 1), the member placed on the front side of the draining device body 1 is It comes into contact with the surface of the rolling roll R. As shown in FIG. 2, the drainer main body 1 has a stripper resin portion 9 made of resin on the front side, and other members such as the holding member 2 are arranged on the stripper resin portion 9. (See also FIG. 4). In this way, by disposing another member on the stripper resin portion 9, heat transmitted from the steel piece P to the draining device main body 1 is further prevented from being transmitted to another member placed on the upper surface thereof. doing. In addition, since the stripper resin 9 receives the load of the weight 8, excessive load on the rubber member 4 can be prevented. The draining device 100 disposed on the lower rolling roll R side has basically the same structure as the draining device 100 disposed on the upper rolling roll R side, except that the weight 8 is not provided.

  The holding member 2 is a member that holds the movable substrate 3. Although the holding member 2 is displayed with a part of its upper surface deleted in FIG. 2, the holding member 2 has a box-like shape as a whole. However, the front surface is open. The holding member 2 accommodates the movable base material 3 therein, but a part of the movable base material 3 is exposed to the outside from the opening surface. The internal width and height of the holding member 2 are formed so as to be slightly larger than the width and thickness of the movable base material 3, respectively. It can move forward or backward in the direction of R. The holding member 2 has a columnar protrusion 10 inside thereof. The protrusions 10 protrude in a direction perpendicular to the moving direction of the movable base 3 and are arranged at equal intervals in the axial direction of the rolling roll R (hereinafter simply referred to as “axial direction”). ing.

  The movable substrate 3 is a member that moves inside the holding member 2. As described above, the movable base material 3 according to the present embodiment is accommodated in the holding member 2 with a part thereof exposed. FIG. 3 is a plan view of a portion of the draining device 100 according to the present embodiment excluding the draining device main body 1. However, the upper surface of the holding member 2 is omitted from the drawing so that the entire movable base material 3 can be seen. As shown in FIG. 3, the movable base material 3 according to the present embodiment has a plate shape and extends substantially parallel to the axis A of the rolling roll. In addition, a plurality of cutout portions 11 cut out toward the inside of the movable base material 3 are formed at the end of the movable base material 3 opposite to the rolling roll R (hereinafter referred to as “rear side”). Has been. In the present embodiment, cutout portions 11 are formed at five locations. The notches 11 are formed at equal intervals in the axial direction, and are formed at positions corresponding to the protrusions 10 of the holding member 2 described above. In addition, the width of the notch 11 is formed to be slightly larger than the diameter of the protrusion 10. Further, an overhanging portion 16 projecting outward is formed on the upper portion of the rear side end portion of the movable base material 3 (see also FIG. 5). In addition, the movable base material 3 is formed with resin.

  The rubber member 4 is a member that contacts the rolling roll R and removes cooling water. As shown in FIG. 2, the rubber member 4 according to the present embodiment is attached to the front side (rolling roll R side) edge of the movable substrate 3. The rubber member 4 is configured such that it can be easily detached from the movable base 3 such as being attached to the movable base 3 using screws. This is because the rubber member 4 is a consumable item and needs to be replaced periodically. FIG. 4 is a side view showing a front portion of the drainer 100 according to the present embodiment. As shown in FIG. 4, the rubber member 4 has a lip portion 12 having a substantially L-shaped cross section at the top of the front end. The front surface of the lip portion 12 comes into contact with the rolling roll R, and the cooling water adhering to the rolling roll R is removed. In addition, as a material of the rubber member 4, abrasion-resistant fluororubber or the like is used.

  The stopper member 5 is a member that prevents an excessive load from being applied to the rubber member 4. As shown in FIG. 2, the stopper member 5 according to the present embodiment is disposed at the rolling roll R side (front side) edge of the movable base 3 and at both ends in the axial direction. In other words, the stopper member 5 is disposed at both ends of the rubber member 4. Further, as shown in FIG. 4, the stopper member 5 has a tip formed in a curved shape, and is disposed so that the surface thereof is located on the inner side (rear side) of the front end of the rubber member 4. Yes. In the case of this embodiment, the stopper member 5 is made of resin, and is configured to be harder and less deformable than the rubber member 4. For this reason, when the rubber member 4 is pushed into the rolling roll R and deformed more than a predetermined amount, the rolling roll R comes into contact with the stopper member 5 and the stopper member 5 supports the rolling roll R. Thereby, the rubber member 4 functions as a stopper, and it is possible to prevent an excessive load from being applied to the rubber member 4 from the rolling roll R. As described above, the excessive load applied to the rubber member 4 is prevented because the rubber member 4 is greatly deformed by the excessive load. This is to prevent excessive wear from occurring.

  The urging member 6 is a member that urges the movable substrate 3 toward the rolling roll R side. As shown in FIG. 3, the draining device 100 according to the present embodiment includes four urging members 6 and is continuously disposed along the movable base 3. Further, the urging members 6 are spaced apart from each other, and each urges the movable substrate 3 independently. Further, in the present embodiment, a leaf spring formed in an annular shape is employed as the biasing member 6. Specifically, an annular leaf spring is formed by combining a pair of plate members 13 formed in an arcuate shape. One of the pair of plate members 13 is fixed to the holding member 2, and the other is fixed to the movable substrate 3. More specifically, the plate member 13 on the holding member 2 side has its central portion fixed to the inner surface of the holding member 2 with screws 17, and the plate member 13 on the movable base 3 side has the center of the movable base 3. It is fixed to the rear surface with screws 17. Therefore, when the movable base material 3 is accommodated in the holding member 2, the ends of the pair of plate members 13 are engaged with each other to form one annular leaf spring. Here, FIG. 5 is a cross-sectional view taken along the line X5-X5 in FIG. As shown in FIG. 5, the pair of plate members 13 are not fixed by welding or the like, but are configured to be able to fit each other.

  The above is the configuration of the drainer 100 according to the present embodiment. Since the draining device 100 according to the present embodiment has the above-described configuration, the following operation is performed. First, when the draining device main body 1 is rotated by the weight 8, the lip portion 12 of the rubber member 4 located near the front end of the draining device main body 1 comes into contact with the surface of the rolling roll R (see FIGS. 1 and 4). Further, when the rubber member 4 receives the force from the rolling roll R as it is, the movable base material 3 is pushed into the holding member 2 against the biasing member 6. And the movable base material 3 stops in the position where the force received from the rolling roll R and the repulsive force of the stripper resin 9 are balanced.

  In addition, when the entire rubber member 4 does not contact the surface of the rolling roll R from the beginning, but only a part of the rubber member 4 initially contacts the surface of the rolling roll R, the contacted portion The portion of the movable substrate 3 corresponding to is strongly pushed. That is, a part of the movable substrate 3 is pushed in, and the entire movable substrate 3 is not pushed uniformly. Therefore, when the movable base material 3 is pushed to some extent, since the urging members 6 are arranged in parallel, the tip portion of the rubber member 4 that was not initially in contact with the surface of the rolling roll R begins to contact gradually, Eventually, the entire rubber member 4 comes into contact with the surface of the rolling roll R.

  Note that when the movable base 3 is pushed into the holding member 2, the protrusion 10 of the holding member 2 gradually enters the notch 11 of the movable base 3. The movement of the movable substrate 3 in the axial direction is limited by the protrusion 10 entering the notch 11. Further, when the protruding portion 10 reaches the bottom of the notch portion 11, the movable base material 3 can no longer be pushed into the holding member 2. Thus, the notch 11 and the protrusion 10 function as a guide and a stopper when the movable substrate 3 moves.

  As described above, according to the draining device 100 according to the present embodiment, the rubber member 4 can be brought into close contact with the surface of the rolling roll R even when the rolling roll R is deformed. Further, uneven wear of the rubber member 4 can be suppressed. In addition, according to the present embodiment, since an air supply source or the like is not necessary, the structure can be greatly simplified, and the manufacturing cost and operation cost of the draining device 100 can be suppressed. Furthermore, according to the present embodiment, when the rolling roll R is exchanged, the movable base 3 is moved forward by the urging member 6, so that the rubber member 4 and the stopper member 5 that are consumables are removed from the movable base 3. Can be easily removed.

(Second Embodiment)
Next, with reference to FIG. 6, the draining device 100 which concerns on 2nd Embodiment of this invention is demonstrated. FIG. 6 is a plan view of a portion of the draining device 100 according to the present embodiment excluding the draining device main body 1 and corresponding to FIG. 3 of the first embodiment. As in the case of FIG. 3, the upper surface of the holding member 2 is omitted from the drawing so that the entire movable base material 3 can be seen. As shown in FIG. 6, the drainer 100 according to the present embodiment has basically the same configuration as the drainer 100 according to the first embodiment. However, in the draining device 100 according to the first embodiment, the movable base material 3 is integrally formed, whereas in the draining device 100 according to the present embodiment, the plurality of partial base materials 3a in which the movable base material 3 is independent. There is a difference that consists of.

  More specifically, in the draining device 100 according to the present embodiment, the movable base material 3 is composed of a plurality of partial base materials 3a each independent. In other words, the movable substrate 3 is divided into a plurality of partial substrates 3a. In the present embodiment, the movable base material 3 is constituted by four partial base materials 3a arranged in the axial direction. Further, as the movable base material 3 is formed in this way, the urging member 6, the notch portion 11, and the protruding portion 10 are also different in arrangement position and the like from the case of the first embodiment. . Specifically, the urging member 6 is disposed corresponding to each partial base material 3a, and one urging member 6 urges one partial base material 3a to the rolling roll R side. It is configured. And the notch part 11 is formed in a pair by the partial base material 3a, and they are formed in the both sides of the part to which the biasing member 6 is being fixed. Further, the protrusion 10 is disposed corresponding to the position where the notch 11 is formed. In the second embodiment, the rubber member 4 is not divided in the axial direction, and is integrally formed. However, the rubber member 4 may be divided so as to correspond to each partial base material 3a.

  The above is the configuration of the drainer 100 according to the present embodiment. Thus, according to the second embodiment, each of the plurality of partial base materials 3a can press the rubber member 4 against the surface of the rolling roll R while moving forward and backward in the direction of the rolling roll R. Even if the surface of R is deformed, the rubber member 4 can be brought into close contact with the surface of the rolling roll R, and the response is very high.

  The first embodiment and the second embodiment according to the present invention have been described above with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the scope of the present invention is not deviated. Any change in design is included in the present invention. For example, although the case where an annular leaf spring is employed as the biasing member 6 has been described above, a coil spring may be employed as the biasing member 6.

  ADVANTAGE OF THE INVENTION According to this invention, although it is a simple structure, even if a rolling roll deform | transforms, the draining device of the rolling roll which can drain water appropriately can be provided. Therefore, it is useful in the technical field of the draining device of a rolling roll.
