Description

Technical Field

[0001] This utility model relates to the technical field of continuous casting slab manufacturing, and in particular to a measuring device. Background Technology

[0002] In the production process of continuously cast slabs, the presence of surface and subsurface defects has a profound impact on the quality of rolled products. Specifically, defects such as transverse cracks, corner cracks, subsurface pinholes, and inclusions not only lead to a large number of scraps in the rolling process but also seriously affect the performance and reliability of the final product. Therefore, the introduction of an automatic slab flame cleaning machine provides an effective solution to improve this situation. This equipment uses a high-temperature flame to melt the slab surface into a liquid state and eliminate defects, forming a groove on the slab surface. This allows for the rapid and effective cleaning of slab surface defects, improving the quality of the finished product.

[0003] When using an automatic flame cleaning machine, it is crucial to pay attention to measuring the slab cleaning thickness. The automatic flame cleaning machine flame-cleans the slab at intervals along its width, creating multiple parallel grooves. A raised corrugated strip is formed at the junction of two adjacent grooves. The distance between the highest point of the upper surface and the highest point of the lower surface of the slab after flame cleaning is the slab thickness. The formula for calculating the slab cleaning thickness is: original slab thickness minus the slab thickness after cleaning. If the cleaning thickness does not meet the standard, it means that surface and subsurface defects in the slab have not been effectively removed, which will directly affect the quality of subsequent rolling processes. Therefore, accurately measuring the slab thickness after cleaning is essential.

[0004] However, in practice, slab cleaning thickness measurement still relies on manual experience, typically using a ruler or tape measure for direct measurement. This method suffers from inconvenience and low accuracy, especially after flame cleaning, when the slab surface becomes corrugated with varying corrugation heights, making accurate data acquisition difficult during manual measurement. This not only increases operational complexity but may also lead to inaccurate assessments of the cleaning effect, thus impacting subsequent production decisions. Utility Model Content

The device includes a first measuring rod, a first level, and a measuring ruler. The slab is placed on a horizontal worktable. The first level is mounted on the first measuring rod. The first measuring rod moves vertically downwards in a horizontal position, contacting two corrugated strips at their highest positions on the slab.

[0010] Preferably, the first measuring rod and the second measuring rod form an integrated L-shaped structure.

[0011] Preferably, the bottom surfaces of both the first measuring rod and the second measuring rod are flat.

[0012] Preferably, the measuring device further includes a telescopic rod, one end of which is fixed to the first measuring rod or the second measuring rod, and the other end can extend outward to the outside of the slab.

[0013] Preferably, the measuring ruler is a pull-out tape measure.

[0028] Example 1

[0029] like Figures 1-2 As shown, this embodiment discloses a measuring device for measuring the thickness of a slab after flame cleaning. Specifically, in the production process of continuously cast slabs, the presence of surface and subsurface defects on the slab 500 has a profound impact on the quality of the rolled product. Specifically, defects such as transverse cracks, corner cracks, subsurface pinholes, and inclusions not only lead to a large number of scraps in the rolling process but also seriously affect the performance and reliability of the final product. Therefore, the introduction of an automatic flame cleaning machine for slabs provides an effective solution to improve this situation. This equipment uses a high-temperature flame to melt the slab surface into a liquid state and eliminate it, forming a groove 510 on the slab surface, which can quickly and effectively clean the defects on the slab surface and improve the quality of the finished product.

[0030] When using an automatic flame cleaning machine, it is crucial to pay attention to the measurement of the slab cleaning thickness. The automatic flame cleaning machine flame-cleans the slab at intervals along its width, creating multiple parallel grooves. A raised corrugated strip is formed at the junction of two adjacent grooves. The distance between the highest point of the upper surface and the lowest point of the lower surface of the slab after flame cleaning is the slab thickness. The formula for calculating the slab cleaning thickness is: original slab thickness minus the slab thickness after cleaning. If the cleaning thickness does not meet the standard, it means that surface and subsurface defects in the slab have not been effectively removed, which will directly affect the quality of subsequent rolling processes. Therefore, accurately measuring the slab thickness after cleaning is essential.

[0031] In this embodiment, the automatic flame cleaning machine performs flame cleaning at intervals along the width direction of the slab 500, and the path of each flame cleaning is along the length direction of the slab 500. Therefore, after the flame cleaning is completed, multiple parallel grooves 510 are formed on the surface of the slab, and raised corrugated strips 520 are formed at the junctions of adjacent grooves 510. The multiple grooves 510 and the multiple corrugated strips 520 are all arranged along the length direction of the slab 500.

[0032] Specifically, the measuring device includes a first measuring rod 100, a first level 110, and a measuring ruler 300. The slab 500 is placed on a horizontal worktable 600. Both the upper and lower surfaces of the slab 500 are flame-treated. The lower surface of the slab 500 is placed horizontally on the horizontal worktable 600. The distance from the highest point of the upper surface of the slab 500 to the horizontal worktable 600 can be approximately equal to the distance from the highest point of the upper surface of the slab 500 to the lowest point of the lower surface of the slab 500. That is, in this embodiment, the thickness of the flame-treated slab 500 is measured by measuring the distance from the highest point of the upper surface of the slab 500 to the horizontal worktable 600 using the measuring ruler 300. Then, the thickness of the flame-treated slab 500 is obtained by subtracting the original thickness of the slab 500 from the original thickness. Based on this thickness, it is determined whether the cleaned thickness of the slab 500 meets the standard. If the cleaned thickness of the slab 500 meets the standard, it means that the defects on the surface and under the slab 500 have been effectively removed, which will directly affect the quality of subsequent rolling processes. Therefore, it is crucial to accurately measure the 500mm thickness of the slab after flame cleaning.

[0033] In this embodiment, the first measuring rod 100 is a cuboid rod structure, and the first level 110 is installed on the upper surface of the first measuring rod 100. The length direction of the first measuring rod 100 is the width direction of the slab 500, that is, the first measuring rod 100 is perpendicular to the grooves 510 and corrugated strips 520 on the upper surface of the slab 500. When locating the highest point on the upper surface of the slab 500, the first measuring rod 100 first moves vertically downward in a horizontal posture until it contacts the upper surface of the slab 500. At this time, the first measuring rod 100 can cover part of the corrugated strips 520 on the upper surface of the slab 500 (the length of the first measuring rod 100 does not exceed the width of the slab 500). The first measuring rod 100 contacts the two higher corrugated strips 520 in this part of the corrugated strips 520 (the lower corrugated strips 520 will not contact the first measuring rod 100), and the highest corrugated strip 520 of these two corrugated strips 520 is found by the deflection of the first level 110. Then, the first measuring rod 100 is moved along the width direction of the slab 500, and the above process is repeated continuously to compare and determine the highest corrugated strip 520 on the entire upper surface of the slab 500, thereby obtaining the highest position of the upper surface of the slab 500. The starting end of the measuring ruler 300 is flush with the lower surface of the first measuring rod 100, and the measuring ruler 300 is set in the vertical direction to measure the distance between the highest corrugated strip 520 on the upper surface of the slab 500 and the horizontal worktable 600, thus obtaining the thickness of the cleaned slab 500.

[0034] In another implementation, the length of the first measuring rod 100 can be set to be greater than or equal to the width of the slab 500, so that the first measuring rod can obtain the corrugated strip 520 at the highest position on the upper surface of the slab 500 in one measurement. This measurement method is more convenient and simpler than the previous measurement method, and can effectively improve measurement efficiency.

[0035] In this embodiment, the measuring device further includes a second measuring rod 200 and a second level 210. The second level 210 is mounted on the second measuring rod 200. The second measuring rod 200 is parallel to the corrugated strip 520 and is used to move along the length direction of the corrugated strip 520 to find the highest point of the corrugated strip 520 in the length direction.

[0036] Since the upper surface of the slab 500 is not completely flat and has a certain degree of inclination or protrusions and depressions, after finding the highest corrugated strip 520 on the upper surface of the slab 500 through the first measuring rod 100, it is also necessary to find the position of the highest point of the highest corrugated strip 520 through the second measuring rod 200.

[0037] Specifically, the second measuring rod 200 is a cuboid rod structure, and the second level 210 is fixedly installed on the upper surface of the second measuring rod 200. After finding the highest corrugated strip 520 on the upper surface of the slab 500 using the first measuring rod 100, the second measuring rod 200 is placed on the corrugated strip 520 and moved along the length of the corrugated strip 520. The highest point of the corrugated strip 520 is found using the second level 210. The method of finding the highest point is to continuously compare the relative heights by adjusting the deflection of the second level 210.

[0038] like Figure 1 As shown, the first measuring rod 100 and the second measuring rod 200 form an integrated L-shaped structure. The first measuring rod 100 and the second measuring rod 200 are perpendicular to each other. This structure is beneficial for the measurement and overall movement of the first measuring rod 100 and the second measuring rod 200. When using the first measuring rod 100 to measure, the second measuring rod 200 can act as a handle. Similarly, when using the second measuring rod 200 to measure, the first measuring rod 100 can act as a handle.

[0039] Furthermore, the bottom surfaces of both the first measuring rod 100 and the second measuring rod 200 are flat, thus ensuring the accuracy and precision of the measurement. Also, the first measuring rod 100 and the second measuring rod 200 are located in the same horizontal plane.

[0040] like Figures 1-2As shown, the measuring device also includes a telescopic rod 400. One end of the telescopic rod 400 is fixed at the connection between the first measuring rod 100 and the second measuring rod 200, and the other end can extend outward to the outside of the slab 500. The measuring ruler 300 is set at the end of the telescopic rod 400 that extends outward, so as to facilitate the measuring ruler 300 to perform measurement.

[0041] Specifically, the measuring ruler 300 is a pull-out tape measure, which is installed inside the telescopic rod 400.

[0042] The specific usage of the measuring device in this embodiment is as follows:

[0043] First, place the flame-cleaned slab on the horizontal worktable 600, ensuring that the lower surface of the slab 500 is in complete contact with the worktable surface to provide a stable reference surface.

[0044] Then, the first measuring rod 100 moves downward in a horizontal position until it contacts the upper surface of the slab 500. Since there are multiple grooves 510 and corrugated strips 520 on the surface of the slab, the first measuring rod 100 will cover two of the higher corrugated strips 520 among several corrugated strips, and find the highest one of these two corrugated strips 520 with the help of the first level 110.

[0045] The first measuring rod 100 is moved gradually along the width direction of the slab 500. The above process is repeated to compare the height of the corrugated strip 520 at different positions and finally determine the highest corrugated strip 520 on the entire surface of the slab 500.

[0046] Once the highest corrugated strip 520 on the surface of the slab 500 is found, the second measuring rod 200 is moved along the length of the corrugated strip, and the second level 210 is used to continuously adjust and find the highest point in the length of the corrugated strip 520.

[0047] Finally, pull out the measuring ruler 300 from inside the telescopic rod 400 to measure the distance from the highest corrugated strip 520 to the horizontal worktable, and obtain the thickness of the flame-treated slab 500.

[0048] The measuring device in this embodiment employs a first measuring rod 100 with a first level 110 and a second measuring rod 200 with a second level 210, which can conveniently and quickly locate the highest point of the corrugated strip 520 on the upper surface of the slab 500, and quickly and efficiently measure the thickness of the flame-treated slab 500 using a measuring ruler 300. Using a measuring device instead of manual measurement greatly improves measurement accuracy. Furthermore, the measuring ruler 300 is a pull-out tape measure installed inside the telescopic rod 400; it is stored inside the telescopic rod 400 when not in use, and can be pulled out simply when measurement is needed, offering high convenience.

[0049] Furthermore, the measuring device in this embodiment not only improves the accuracy and efficiency of measurement, but also simplifies the operation process through its integrated design, reducing errors caused by human factors. Moreover, the convenient design of the measuring ruler makes the entire measurement process more flexible and efficient.

[0050] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
