Description

Technical Field

[0001] The utility model relates to the technical field of refractory material processing and production, in particular to a ladle slide brick sleeve hoop positioning tool for a sliding water nozzle. Background Art

[0002] The sliding nozzle is a control device that accurately adjusts the molten steel flow from the ladle to the continuous casting tundish during the casting process of the continuous casting machine. The sliding plate brick, as the most critical refractory component in the sliding nozzle, is the key part that determines the function of the nozzle. The quality of the sliding plate brick directly affects whether there is a risk of steel leakage in the ladle.

[0003] The compacted and flattened skateboard bricks are thick, so in order to prevent thermal shock cracks from occurring in the brick body during operation, it is often necessary to surround them with steel hoops at a certain height on their outer periphery (i.e., the hooping process). The existing hooping is done manually. During the operation, in order to ensure that the steel hoop is accurately put into place at one time, a bearing plate is often set to stably support the skateboard bricks, and multiple positioning blocks corresponding to the outer periphery of the skateboard bricks are fixedly arranged on the bearing plate. Then, the skateboard brick is firmly clamped on the bearing plate inside the positioning blocks, and the hooping operation can be manually performed.

[0004] The fixed positioning block can only be used to position and fix a skateboard brick of a certain specific contour, and its adaptability is relatively limited. A set of sleeve positioning tooling must be designed for a model of skateboard brick, and the processing cost is relatively high. In addition, when using it, the corresponding sleeve positioning tooling must be taken according to the model of the skateboard brick, and taking and taking is relatively cumbersome. In addition, the positioning block contacts the side edge point of the skateboard brick, the fit is poor, the force is relatively concentrated, and it is easy to cause cracks and other damage to the positioning and fixing part of the skateboard brick. Summary of the invention

[0005] The utility model aims to provide a positioning tool for a ladle slide brick sleeve hoop in view of the defects of the prior art.

[0006] In order to achieve the above purpose, the utility model can adopt the following technical solutions:

[0007] The ladle slide brick sleeve hoop positioning tool described in the utility model comprises:

[0008] A horizontal carrier plate having a plurality of pairs of first fixing holes and second fixing holes with internal threads uniformly distributed thereon;

[0009] There are two first positioning clamps, each of which has a first positioning edge for supporting the outer edge of the ladle slide brick, and a first connecting long hole is opened on the first positioning clamp in the width direction, and a first fastening bolt matching the first fixing hole is passed through the first connecting long hole;

[0010] The second positioning card board, there are two of them, and each said second positioning card board has a second positioning edge for propping up the outer edge of the ladle slide brick. A second connecting long hole is opened in the second positioning card board along the width direction, and a second fastening bolt matching the second fixing hole is inserted into the second connecting long hole.

[0011] Specifically, both the first positioning card board and the second positioning card board are right trapezoid structures. The length direction of the first connecting long hole is parallel to the upper and lower bases of the first positioning card board with a right trapezoid structure, and the length direction of the second connecting long hole is parallel to the upper and lower bases of the second positioning card board with a right trapezoid structure.

[0012] Furthermore, to prevent the installation positions of the first positioning card board and the second positioning card board on the horizontal carrier board from being upside down, an anti-fooling chamfer can also be set at a corner of the horizontal carrier board, so as to clearly distinguish the upper and lower edges of the horizontal carrier board, facilitating the accurate installation of the first positioning card board and the second positioning card board onto the horizontal carrier board.

[0013] The advantages of the present utility model are as follows: Through multiple pairs of first and second fixing holes opened on the horizontal carrier board, in cooperation with the first connecting long holes opened on the two first positioning card boards and the second connecting long holes opened on the two second positioning card boards, the fine adjustment of the positions of the first and second positioning card boards in all directions on the bearing plane of the horizontal carrier board can be easily achieved; and the first and second fastening bolts can be used to realize the horizontal rotation of the first and second positioning card boards at any angle on the bearing plane and subsequent pressing and fixing, enhancing the adaptability of the entire ladle slide brick hoop positioning tooling, being able to match various types of ladle slide bricks, and being able to achieve surface-to-surface contact between the first and second positioning card boards and the outer edge of the slide brick, ensuring the fitting property while avoiding the phenomenon of concentrated stress on the outer edge of the slide brick and preventing damage to the slide brick.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] As Figures 1-4 shown, the ladle slide brick hoop positioning tooling of the present utility model includes a horizontal carrier plate 1, and a first positioning card plate 2 and a second positioning card plate 3 arranged thereon.

[0020] Specifically, the top surface of the horizontal carrier plate 1 is a bearing plane for supporting the ladle slide brick. Along the length direction on the bearing plane of the horizontal carrier plate 1, there are multiple pairs of first fixing holes 4 with internal threads and multiple pairs of second fixing holes 5 with internal threads. The first fixing holes 4 are arranged in the upper half of the horizontal carrier plate 1, while the second fixing holes 5 are arranged in the lower half of the horizontal carrier plate 1.

[0021] There are two first positioning card plates 2. Each first positioning card plate 2 has a first positioning edge 6 for propping against the outer edge of the ladle slide brick. And along the width direction on each first positioning card plate 2, there is a first connecting long hole 7. A first fastening bolt 8 that can be adapted and screwed with the first fixing hole 4 is inserted into the first connecting long hole 7. By the first fastening bolt 8 passing through the first connecting long hole 7 and being screwed and fixed in the first fixing hole 4 to press the first positioning card plate 2, the first positioning card plate 2 is fixed on the horizontal carrier plate 1.

[0022] There are also two second positioning card plates 3. Each second positioning card plate 3 has a second positioning edge 9 for propping against the outer edge of the ladle slide brick. And along the width direction on each second positioning card plate 3, there is a second connecting long hole 10. A second fastening bolt 11 that can be adapted and screwed with the second fixing hole 5 is inserted into the second connecting long hole 10. By the second fastening bolt 11 passing through the second connecting long hole 10 and being screwed and fixed in the second fixing hole 5 to press the second positioning card plate 3, the second positioning card plate 3 is fixed on the horizontal carrier plate 1.

[0023] In addition, both the first positioning card plate 2 and the second positioning card plate 3 are plate bodies with a right trapezoidal structure. At this time, the hypotenuse of the first positioning card plate 2 is the first positioning edge 6, the hypotenuse of the second positioning card plate 3 is the second positioning edge 9, and the length direction of the first connecting long hole 7 should be parallel to the upper and lower bottoms of the first positioning card plate 2 with a right trapezoidal structure, and the length direction of the second connecting long hole 10 should be parallel to the upper and lower bottoms of the second positioning card plate 3 with a right trapezoidal structure.

[0024] Further, to prevent the first positioning card board 2 and the second positioning card board 3 from being installed upside down on the horizontal carrier plate 1, an anti-fooling chamfer 12 can be provided at a corner of the horizontal carrier plate 1, so as to clearly distinguish the upper and lower edges of the horizontal carrier plate 1, facilitating the accurate installation of the first positioning card board 2 on the upper half of the horizontal carrier plate 1 and the second positioning card board 3 on the lower half of the horizontal carrier plate 1.

[0025] During use, first, place the ladle slide brick steadily at the center position of the bearing plane of the horizontal carrier plate 1, and install the two first positioning card boards 2 and the two second positioning card boards 3 according to the outer contour of the slide brick, ensuring that the first positioning edges 6 of the two first positioning card boards 2 and the second positioning edges 9 of the two second positioning card boards 3 all face the slide brick.

[0026] Then, utilize the multiple pairs of first fixing holes 4 and second fixing holes 5 provided on the horizontal carrier plate 1, the first connecting long holes 7 provided on the two first positioning card boards 2, and the second connecting long holes 10 provided on the two second positioning card boards 3 to easily achieve the position translation of the first positioning card board 2 in the arrangement direction of the first fixing holes 4 and the length direction of the first connecting long holes 7, and the position translation of the second positioning card board 3 in the arrangement direction of the second fixing holes 5 and the length direction of the second connecting long holes 10, realizing the precise position adjustment of the first positioning card board 2 and the second positioning card board 3 in all directions on the bearing plane of the horizontal carrier plate 1, so that the first positioning edges 6 of the two first positioning card boards 2 can abut against the upper left and right sides of the slide brick, and the second positioning edges 9 of the two second positioning card boards 3 can abut against the lower left and right sides of the slide brick.

[0027] After that, the first fastening bolts 8 and the second fastening bolts 11 can also be used to achieve the horizontal rotation of the first positioning card board 2 and the second positioning card board 3 at any angle on the bearing plane and subsequent pressing and fixing, so that the two first positioning edges 6 and the two second positioning edges 9 can be in contact with the outer edge of the slide brick as large as possible, enhancing the adaptability of the entire ladle slide brick hoop positioning tooling, matching various models of ladle slide bricks, realizing the surface-to-surface contact between the first positioning card board 2 and the second positioning card board 3 and the outer edge of the slide brick, ensuring the fitting property while avoiding the phenomenon of concentrated stress on the outer edge of the slide brick and preventing damage to the slide brick.

[0028] After the above adjustments are completed, the steel hoop can be heated and then placed on the slide brick, and the heated steel hoop is tapped to make it surround the outer circumference of the slide brick and drop onto the first positioning card board 2 and the second positioning card board 3. At this time, the steel hoop is controlled at the required height of the slide brick. When the temperature of the steel hoop cools down, it tightly wraps around the outer circumference of the slide brick, completing the entire process of hooping the slide brick.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly.

[0030] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.
