Description

Technical Field

[0001] This utility model belongs to the field of metallurgical continuous casting process equipment, and in particular relates to a special device for online measurement of the high-temperature cross-sectional dimensions of continuously cast billets. Background Technology

[0002] In the continuous casting process, accurate measurement of the cross-sectional dimensions of the continuously cast billet is crucial for ensuring product quality. Continuous casting is a continuous high-temperature operation; the surface temperature of the billet after leaving the crystallizer is typically above 1000℃. After passing through the straightening machine, the temperature is between 800-900℃, and personnel need to confirm whether the cross-sectional dimensions of the billet meet the requirements.

[0003] In existing technologies, a steel ruler is commonly used to measure the cross-section of a cut steel billet. This measurement method is based on a simple length comparison principle. The operator holds the steel ruler, aligns it with the edge of the billet's cross-section, and reads the scale value to obtain dimensional information. Therefore, existing measurement schemes mainly rely on operators using a steel ruler. After the billet is cut and moved to the cooling bed, the operator lies on the billet and places the steel ruler close to the edge of the cross-section for measurement. Only the steel ruler is needed as a measuring tool, but in practice, it relies entirely on manual alignment and reading, lacking precise positioning and guiding structures in the measurement process.

[0004] Therefore, the existing technology has the following problems:

[0005] 1. Problem of low measurement accuracy: When measuring with a handheld steel ruler, it is difficult to ensure that the ruler body is precisely aligned with the edge of the steel billet cross section, and the reading is easily affected by factors such as viewing angle and shaking, resulting in large measurement deviations and failing to meet the requirements of high-precision production.

[0006] 2. High safety hazards: The temperature of the steel billet is extremely high after cutting. Operators need to lie on the steel billet to measure it, which means they are in close contact with the high-temperature area and are very likely to be burned. At the same time, protective gear is easily burned in the high-temperature environment, which poses a serious threat to the personal safety of operators.

[0007] 3. Measurement lag: After the steel billet is cut, it must be transported to the cooling bed to cool before it can be measured. It is impossible to measure it on the cutting site in real time, which leads to untimely quality feedback, affects the rapid adjustment of subsequent process parameters, and reduces production efficiency and the timeliness of product quality control. Utility Model Content

[0008] The purpose of this invention is to provide a special device for online measurement of the high-temperature cross-sectional dimensions of continuously cast billets, so as to solve the problems of low accuracy, high risk of defects, and lag in the existing technology when measuring the high-temperature cross-sectional dimensions of continuously cast billets.

[0009] This utility model adopts the following technical solution: a special device for online measurement of the high-temperature cross-sectional dimensions of continuously cast billets, comprising:

[0010] The scale rod is set vertically; its lower end is fixedly connected to a lower end latching rod, and the direction of the lower end latching rod is perpendicular to that of the scale rod.

[0011] The sliding rod is vertically set and parallel to the scale rod; its lower end is fixedly connected to the upper end latching rod, and the upper end latching rod is perpendicular to the direction of the sliding rod.

[0012] A fixed short tube is fitted onto the scale rod and fixedly connected to it;

[0013] A sliding sleeve is fitted onto a sliding rod, allowing the sliding rod to slide up and down along its path; the sliding sleeve is fixedly connected to a fixed short tube via a horizontally set connecting rod; thus allowing the sliding rod to slide up and down relative to the scale rod.

[0014] The upper half of the scale rod is equipped with a scale, with the zero point of the scale located close to the fixed short tube; the outer wall of the sliding rod is marked with a mark, and the distance between the mark and the upper snap-in rod is equal to the distance between the zero point of the scale rod and the lower snap-in rod.

[0015] The steel billet is inserted between the upper and lower locking rods for horizontal placement. The scale value on the scale rod corresponding to the mark on the sliding rod is then read to obtain the cross-sectional dimensions of the steel billet.

[0016] The beneficial effects of this utility model are:

[0017] This utility model can achieve accurate measurement, ensure the safety of operators, and meet the needs of online real-time measurement, so as to improve the measurement accuracy, safety and production efficiency in the steelmaking continuous casting production process and ensure stable control of product quality.

[0018] This invention can solve the problems of low accuracy, easy burns to personnel, and measurement lag when using traditional steel rulers to measure the cross-sectional dimensions of cast billets.

[0019] This invention allows the cross-sectional dimensions of a steel billet to be obtained directly by reading the scale value on the scale rod corresponding to the mark on the sliding rod, without the need for secondary calculation;

[0020] This invention breaks through the bottleneck of traditional measurement accuracy when measuring the cross-section of cast billets; it not only ensures that the operation is away from high-temperature and dangerous areas, but also provides stable guidance for measurement; it enables real-time online measurement at the cutting site, without waiting for the billet to cool and be transferred, and timely provides accurate data for subsequent process adjustments.

[0021] This invention significantly improves measurement accuracy, eliminates the risk of burns to personnel, optimizes production processes through timely measurement feedback, and significantly improves production efficiency and quality control, providing the steelmaking and continuous casting industry with accurate, safe, and efficient measurement capabilities.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more. The term "orientation" in this utility model refers to the orientation of the utility model within the... Figure 1 Description of the state's progression.

[0027] This utility model discloses a special device for online measurement of the high-temperature cross-sectional dimensions of continuously cast billets, such as... Figure 1 As shown, it includes: a scale rod 10, a sliding rod 11, a fixed short tube 12, and a sliding sleeve 13.

[0028] The scale rod 10 is set vertically; the lower end of the scale rod 10 is fixedly connected to the lower end snap-in rod 16, and the lower end snap-in rod 16 is perpendicular to the direction of the scale rod 10.

[0029] The sliding rod 11 is vertically arranged and parallel to the scale rod 10; the lower end of the sliding rod 11 is fixedly connected to the upper end latching rod 15, and the upper end latching rod 15 is perpendicular to the direction of the sliding rod 11.

[0030] The fixed short tube 12 is sleeved on the scale rod 10 and is fixedly connected to the scale rod 10; the sliding sleeve 13 is sleeved on the sliding rod 11 and allows the sliding rod 11 to slide up and down along its direction; the sliding sleeve 13 is fixedly connected to the fixed short tube 12 through a horizontally set connecting rod; thereby allowing the sliding rod 11 to slide up and down relative to the scale rod 10.

[0031] The upper half of the scale rod 10 is equipped with a scale, with the zero point 14 of the scale positioned close to the fixed short tube 12. A mark is provided on the outer wall of the sliding rod 11, and the distance between the mark and the upper snap-in rod 15 is equal to the distance between the zero point 14 of the scale rod 10 and the lower snap-in rod 16. When calculating this distance, the distance between the mark and the lower edge of the upper snap-in rod 15, and the distance between the zero point 14 of the scale rod 10 and the upper edge of the lower snap-in rod 16 are calculated, thus ensuring that the distance between the lower edge of the upper snap-in rod 15 and the upper edge of the lower snap-in rod 16 is exactly equal to the cross-sectional diameter of the steel billet.

[0032] The upper latching rod 15 and the lower latching rod 16 are used to insert a horizontally placed steel billet, and the scale value on the scale rod 10 corresponding to the mark on the sliding rod 11 is read to obtain the cross-sectional dimensions of the steel billet.

[0033] The distance between the zero point 14 on the scale rod 10 and the lower latching rod 16 is 130-150cm. This design allows personnel to read the specific dimensions of the steel billet cross-section while standing, eliminating the need to bend over, thus increasing measurement speed and reducing labor intensity.

[0034] The upper latching rod 15 and the lower latching rod 16 are parallel to each other and located on the same side. Setting them on the same side makes it easier for personnel to operate, and also makes it easier for the upper latching rod 15 and the lower latching rod 16 to extend into the upper and lower sides of the steel billet, respectively.

[0035] This invention improves measurement accuracy, reduces errors caused by manual operation, and makes measurement results more accurate and reliable. It meets the high-precision measurement requirements of billet dimensions in steelmaking continuous casting processes, thereby improving product quality stability. Operators do not need to be in close contact with high-temperature steel billets, avoiding burns and protecting their protective gear, reducing labor protection costs and complying with industrial production safety regulations. It enables online, real-time measurement, eliminating the need to wait for billet cooling and transportation, and providing timely feedback of measurement data. This allows production personnel to quickly adjust subsequent process parameters, reducing production delays caused by measurement lags, improving overall production efficiency, and enhancing the company's competitiveness in the market. Operators can quickly approach and measure the billet after cutting, without complicated preparation. The tool's structure is simple and easy to understand; after simple training, operators can master its use. On steelmaking continuous casting production lines, this tool can be configured as a standard measuring tool, seamlessly integrating with existing production processes without interfering with the original production rhythm, while effectively improving the efficiency and quality of the measurement process.

[0036] Example

[0037] A steel mill currently uses a manual method of holding a steel ruler, aligning the ruler with the edge of the billet's cross-section, and reading the scale value to obtain dimensional information. Therefore, the existing measurement method relies heavily on operators using a steel ruler. After the billet is cut and moved to the cooling bed, the operator lies on the billet and holds the steel ruler close to the cross-sectional edge to take measurements.

[0038] This invention is made using existing materials: two 1-meter-long stainless steel pipes, two 4×10 cm steel plates with a thickness of 3 mm, and two interconnected fixed short pipes 12 and sliding sleeves 13. A scale rod 10 and a sliding rod 11 are made from the two stainless steel pipes, and an upper snap-in rod 15 and a lower snap-in rod 16 are made from the two steel plates. Scales are marked on the scale rod 10. The distance between the zero point 14 on the scale rod 10 and the lower snap-in rod 16 is 150 cm.

[0039] The specific usage process is as follows:

[0040] After the steel billet is cut, the operator holds the measuring tool and aligns the upper locking rod 15 and the lower locking rod 16 with the cross-section of the billet. By moving the sliding rod 11, the lower edge of the upper locking rod 15 and the upper edge of the lower locking rod 16 are made to fit tightly against the upper and lower or left and right sides of the cross-section of the billet. At this time, by observing and reading the scale value on the scale rod 10 corresponding to the mark on the sliding rod 11, the cross-sectional dimensions of the steel billet can be obtained.

[0041] Throughout the measurement process, the sliding sleeve 13 guides the sliding rod 11, ensuring its vertical or horizontal movement and thus guaranteeing measurement accuracy. Simultaneously, operators do not need to be close to the high-temperature steel billet; they can complete the measurement from a suitable distance, greatly improving operational safety and achieving precise measurement of the billet's cross-sectional dimensions, breaking through the accuracy limitations of traditional steel ruler measurements. It can be used directly at the billet cutting site, eliminating the need to wait for the billet to cool and be transported to the cooling bed, enabling online, real-time measurement. This provides timely and accurate data support for subsequent process adjustments, improving the continuity of the production process and the timeliness of quality control.
