Description

Technical Field

[0001] This utility model relates to the field of steel billet measuring tools, and in particular to a device for measuring the width and thickness of high-temperature steel billets. Background Technology

[0002] In the production process of medium and heavy plates, the width and thickness of the high-temperature billets must be checked and verified before they are loaded and cut to ensure that the product specifications meet the requirements of subsequent processing. However, after heat treatment, the billets are usually in a high-temperature state ranging from 300 to 700°C.

[0003] In previous spot checks, steel billets were routinely measured using a measuring tape. However, due to the extremely high temperature of the billets, the measuring tape is easily damaged by the heat when in contact with or near the hot billet. This not only significantly shortens the lifespan of the measuring tape and increases the cost of the measuring tool, but also makes it difficult for measuring personnel to get close to the hot billet for accurate measurements due to concerns about tape damage and their own safety. Furthermore, because of the high temperature and potentially uneven surface of the steel billet, it is difficult for measuring personnel to quickly and stably position the measuring tape. Measuring width and thickness requires considerable time and repeated adjustments, making it difficult to quickly measure these dimensions. Ultimately, this results in significant deviations in the measurements of the hot billets, failing to provide accurate data support for subsequent production and severely impacting production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide a width and thickness measuring device suitable for high-temperature steel billets. This device can solve the problems of inconvenient measurement and difficulty in rapid and accurate measurement in existing high-temperature steel billet width and thickness measuring devices.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: This width and thickness measuring device suitable for high-temperature steel billets includes a width measuring steel ruler, a thickness measuring steel ruler, and a frame spanning the high-temperature steel billet. The width measuring steel ruler and the thickness measuring steel ruler are respectively fixed on the frame. The frame is made of a high-temperature resistant straight rod. One end of the straight rod is bent to form a clamp for fitting against the side of the high-temperature steel billet, and the other end is bent to form a grip ring. The width measuring steel ruler is set along the length direction of the straight rod, and the starting measurement point of the width measuring steel ruler is aligned with the inner side of the clamp. The thickness measuring steel ruler is perpendicular to the straight rod, and the distance between the clamp and the thickness measuring steel ruler is greater than the width of the high-temperature steel billet to be measured.

[0006] A more specific technical solution for the width and thickness measuring device for high-temperature steel billets described above could be: the reading surfaces of the width-measuring steel ruler and the thickness-measuring steel ruler are oriented in the same direction, and the reading surfaces are perpendicular to the upper surface of the high-temperature steel billet.

[0007] The reading face of the width measuring steel ruler faces upwards, and the reading face of the thickness measuring steel ruler faces one end of the grip ring.

[0008] The straight rod is made of round steel.

[0009] In some possible implementations, the diameter of the round steel bar is 10 mm or more.

[0010] In some possible implementations, the distance between the thickness measuring steel ruler and the grip ring is greater than 0.3m.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0012] 1. The overall frame structure made of high-temperature resistant straight rods ensures the stability of the device in high-temperature environments. The clamp design facilitates the positioning of the device on the steel billet, enabling high-precision measurement of the billet dimensions. At the same time, the grip ring makes it easy for the measuring personnel to grasp and measure. The frame is equipped with steel plate rulers for measuring width and thickness, enabling rapid measurement of the width and thickness of high-temperature steel billets. The relevant distance limits allow the measuring personnel to maintain a certain distance from the hot billet, reducing safety hazards, thus enabling the entire measurement process to be completed more efficiently, accurately, and safely.

[0013] 2. The reading surfaces are aligned with the same direction and perpendicular to the upper surface of the billet, which makes it easier for the measuring personnel to observe the width and thickness readings at the same time. This reduces the inconvenience and errors caused by inconsistent reading directions during the measurement process, and further improves the accuracy and efficiency of the measurement.

[0014] 3. The setting of having the reading face of the width measuring steel ruler facing upwards and the reading face of the thickness measuring steel ruler facing the end of the grip ring allows the measuring personnel to more easily read the width and thickness values ​​during the measurement process, based on their operating habits and perspectives. This optimizes the measurement operation process and improves the convenience and accuracy of the measurement.

[0015] 4. The straight rods are made of round steel, which can ensure the structural stability and durability of the frame in high-temperature environments, reduce deformation or damage caused by high temperatures, and thus ensure the long-term stable operation of the measuring device and improve the reliability of measurement.

[0016] 5. The diameter of the round steel bar is 10mm or more, which can improve the strength and rigidity of the straight bar, making it less prone to bending or deformation when subjected to external forces and high-temperature environments during the measurement process. This further ensures the stability and accuracy of the measuring device and extends its service life.

[0017] 6. The distance between the steel ruler and the grip ring is more than 0.3m, which ensures that the measuring personnel maintain a sufficient distance from the high-temperature steel billet when operating the device. This reduces the heat radiation and potential dangers to the measuring personnel caused by being close to the high-temperature steel billet, improves the safety of the measurement process, and also helps the measuring personnel to perform the measurement operation more comfortably and stably, indirectly improving the accuracy and efficiency of the measurement.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0023] Figures 1 to 3 The width and thickness measuring device for high-temperature steel billets shown mainly includes a frame 1, a width measuring steel ruler 2, and a thickness measuring steel ruler 3. The frame 1 is integrally made of a high-temperature resistant straight rod. One end of the rod is bent to form a "7"-shaped clamp 1-1 for fitting against the side of the high-temperature steel billet 4, and the other end is bent to form a grip ring 1-2 for easy holding. The width measuring steel ruler 2 is fixedly welded along the length of the straight rod, and its starting measurement point is strictly aligned with the inner side of the clamp 1-1 to ensure the accuracy of the width measurement reference. The thickness measuring steel ruler 3 is welded perpendicular to the straight rod and located in the vertical part of the frame 1. The distance between it and the clamp 1-1 is greater than the maximum width of the high-temperature steel billet 4 to be measured, ensuring that the device can stably straddle the steel billet.

[0024] In this embodiment, frame 1 is made of round steel with a diameter of 10mm or more, with an overall length of 2700mm and a height of 300mm, to accommodate the size range of common high-temperature steel billets 4. Round steel exhibits excellent resistance to deformation and burn-off under high-temperature conditions, ensuring long-term stable use. The clamp 1-1 of frame 1 is designed to fit tightly against the side of the steel billet, providing a precise positioning reference for measurement. The grip ring 1-2 is located at the other end of frame 1, and its distance from the thickness gauge ruler 3 is maintained at more than 0.3m, ensuring a safe distance between the measuring personnel and the high-temperature steel billet.

[0025] In this embodiment, the width measuring steel plate ruler 2 is welded and fixed along the straight rod direction, with a length of 2200mm to cover a sufficient measurement range. Since the starting point of the ruler is aligned with the inner side of the clamp 1-1, during measurement, the width value of the steel billet can be directly read from the ruler simply by pressing the clamp 1-1 against the edge of the steel billet. This avoids errors caused by pulling or inaccurate positioning during traditional tape measure measurements, and the measurement accuracy can reach ±1mm. The thickness measuring steel plate ruler 3 is 300mm long and is vertically welded to the straight rod.

[0026] In some possible embodiments, the reading surfaces of the width measuring steel ruler 2 and the thickness measuring steel ruler 3 are oriented in the same direction and perpendicular to the upper surface of the steel billet, so that the measuring personnel can observe the width and thickness readings at the same time.

[0027] In some other possible embodiments, the reading surface of the width measuring steel ruler 2 is set upwards, making it convenient for the operator to read the data from above. The reading surface of the thickness measuring steel ruler 3 is set towards the grip ring.

[0028] In the measurement process for width and thickness sampling and verification during the billet receiving stage of the sheet metal production line, the measuring personnel first place the width and thickness measuring device across the high-temperature billet 4, ensuring that the clamp 1-1 is tightly against one edge of the high-temperature billet 4, and that the straight rod of the frame 1 is perpendicular to the side edge of the high-temperature billet 4. At this point, the reading on the width measuring steel ruler 2 corresponding to the other side of the high-temperature billet 4 is the width of the billet. Subsequently, the width and thickness measuring device is moved in the opposite direction, so that the thickness measuring steel ruler 3 contacts the side edge of the high-temperature billet 4, and the thickness value corresponding to the lower edge of the high-temperature billet 4 is read. The measurement data of width and thickness are recorded for subsequent billet sampling and verification. The entire measurement process does not require repeated adjustment of the tool position and can be completed quickly by a single person in less than 10 seconds, which is more than 3 times more efficient than traditional tape measure measurement.

[0029] This width and thickness measuring device integrates width and thickness measurement functions into one unit. Its simple and reasonable structure enables high-precision and high-efficiency measurement of steel billet dimensions under high-temperature environments. The frame structure allows the operator to maintain a safe distance of 0.3~0.5m from the high-temperature steel billet at all times, significantly reducing the risk of burns. Meanwhile, the high-temperature resistant steel ruler and frame design ensure high durability and significantly reduce tool replacement costs.
