Description

Technical Field

[0001] The present invention relates to the technical field of continuous casting machines, and in particular to a device for detecting the rotation condition of a continuous casting sector roller system. Background Art

[0002] In the metallurgical industry, continuous casting machines are primarily used for continuous casting operations and are closely linked to the overall production level and efficiency of a steel mill. Controlling the rotation of the segment rollers on these machines directly impacts the quality of the cast strands, further impacting the quality of the rolling mill coils and even leading to production accidents such as steel buildup. Therefore, personnel must consider various factors, strengthen segment roller monitoring, and perform maintenance to ensure the effectiveness of the continuous casting machine segments.

[0003] Typically, continuous casting machine segment rollers are segmented, particularly on thin slab continuous casting machines. The gap between the rollers is less than 200mm, creating a confined operating space. Conventional tools make it difficult to accurately determine roller rotation. This necessitates long machine downtimes to measure the gap using a roll gap meter, which requires long operation times and limits flexibility. Operators and inspectors often lack timely visibility into segment roller rotation, leading to the accumulation of iron oxide scale in areas where the rollers are not rotating, causing scratches on the cast slab. Failure to promptly detect the slab entering the rolling mill can lead to coil quality issues and even steel pile-up accidents, posing production and quality risks. Summary of the Invention

[0028] Please refer to Figure 1 , discloses a device for detecting the rotation condition of a continuous casting sector roller system, comprising a base 100, a bearing 200, a universal joint 300, a torque wrench 400 and a drive head 500.

[0029] The base 100 is fixedly mounted on the sector frame, the bearing 200 is fixed on the base 100, and the universal joint 300 includes a first rod 310, a universal joint 320, and a second rod 330 connected in sequence. The first rod 310 is fixedly penetrated through the inner ring of the bearing 200, and the torque wrench 400 is connected to one end of the first rod 310. The torque wrench 400 and the universal joint 320 are located on opposite sides of the bearing 200. The driving force is provided by the torque wrench 400, and the drive head 500 is connected to the end of the second rod 330 away from the universal joint 320.

[0030] The drive head 500 is configured to extend into the gap between two adjacent outer-arc rollers 21 and two adjacent inner-arc rollers 22 in the segment roller system. The inner-arc rollers 22 in the segment roller system are equipped with hydraulic cylinders. These hydraulic cylinders work together to press the inner-arc rollers 22 against the drive head 500, which also presses the drive head 500 against the outer-arc rollers 21. During testing, the lower drive head 500 presses against both the outer-arc rollers 21 and the inner-arc rollers 22 in the gap between them.

[0031] During specific implementation, the device is installed on the sector frame through the base 100, the universal shaft 300 is installed in the bearing 200 of the base 100, the drive head 500 is connected to the universal shaft 300, and the rotation of the drive head 500 is satisfied by the universal shaft 300; during inspection, the drive head 500 is extended into the gap of the sector roller system, specifically the gap between two adjacent outer arc rollers 21 and two adjacent inner arc rollers 22, and the inner arc roller 22 is moved downward by controlling the oil cylinder of the sector roller system itself until the drive head 500 is tightly against the two outer arc rollers 21 and the drive head 500 is tightly against the two inner arc rollers 22, and then a torque of a certain size is applied by the torque wrench 400, and the drive head 500 is driven to rotate through the universal shaft 300, and the suspected roller is observed to rotate normally under the specific torque, and the rotation of the sector roller is quickly detected and confirmed to be in good condition.

[0032] By providing a universal shaft 300, this device can achieve multi-angle measurement, facilitate the arrangement of the drive head 500 in space, and facilitate the universal shaft 300 to extend into multiple gaps in the sector, thereby expanding the scope of use of the detection device and being suitable for the detection of a large number of rollers; this device has the advantages of easy assembly and disassembly and simple and easy operation; this device can quickly detect and confirm the rotation status of the sector rollers, saving about 60 minutes of time for overall measurement using a roll gap meter; this device can be used for the detection of most sector rollers of continuous casting machines, has a wide range of applications, and can be widely used.

[0033] In some embodiments, the second rod 330 in the universal shaft 300 is configured as a retractable coupling, enabling detection of long rollers and ensuring a full detection range for segmented rollers. Given the retractable nature of the universal shaft 300, this device enables comprehensive detection of the rotation of the segmented roller system.

[0034] In some embodiments, the driving head 500 is a solid rubber structure made of rubber material, which not only ensures that the above-mentioned tightness requirements are met, but also has considerable friction with the roller, and can smoothly drive the roller to rotate.

[0035] When the driving head 500 is a solid rubber structure, the driving head 500 may be selected to have a diameter of 120 mm, and the design value may be adjusted according to the actual situation of the sector segment.

[0036] In some embodiments, the base 100 is removably mounted on the segment frame.

[0038] In some embodiments, as Figure 1 As shown in FIG, the base 100 is made of a stainless steel square tube, and includes a main body portion and a small portion for mounting the bearing 200 .

[0039] On the whole, this device can quickly check suspected rollers in the sector segment. If a dead roller is found, online processing or sector segment replacement can be arranged in time, effectively ensuring the quality of the continuous casting machine's billets and avoiding production accidents caused by abnormal raw materials in the rolling mill.
