Technical Field

[0001] The utility model belongs to the technical field of continuous steel casting, and in particular relates to a crystallizer ingot cage calibration device. Background Art

[0002] When the rectangular billet continuous casting machine seals the ingot head before pouring, the dimensional deviation of the ingot cage can easily cause equipment accidents such as scratching the copper tube of the crystallizer, unhooking, and steel leakage.

[0003] However, if the size of the self-made dummy cage is too large or too small, it is not good for continuous casting; if the size of the self-made dummy cage hook rod is too small or the welding angle is biased, it will not prevent the hook from coming off, there is a risk of steel leakage, and it is very easy to cause the problem of leakage in the dovetail slot cavity. If the size of the self-made dummy cage hook rod is too large, it will not fit into the dovetail slot of the dummy head, and it is easy to scratch the shell of the crystallizer and cannot be used.

[0004] At present, the crystallizer dart cage is calibrated by manual measurement with a tape measure. Since the finished product dart cage is a three-dimensional structure, this measurement method leads to large errors in the measured size values ​​and cannot ensure that the crystallizer dart cage meets the production process requirements.

[0005] The utility model aims at the defects in the prior art and provides a crystallizer ingot cage calibration device.

[0006] To achieve the above objectives, the utility model adopts the following technical scheme, including a base plate, a first vertical plate, a second vertical plate, a first sliding plate, a second sliding plate, a first guide shaft, a second guide shaft, a third guide shaft, a fourth guide shaft, a support plate and an adjusting bolt.

[0008] One end of the first sliding plate is respectively passed through by the first guide shaft and the second guide shaft, and is slidably connected to the first group of guide shafts. One end of the second sliding plate is passed through by the third guide shaft and the fourth guide shaft, and is slidably connected to the second group of guide shafts, thereby realizing the sliding of the sliding plate along the guide shafts.

[0009] The other end of the first sliding plate is perpendicular to the other end of the second sliding plate, and together with the first vertical plate and the second vertical plate, forms a rectangular frame for accommodating the ingot cage.

[0010] Furthermore, the first sliding plate and the second sliding plate are both provided with a strip hole slideway, and the support plate is slidably connected to the corresponding sliding plate through an adjusting bolt, and the support plate can be slid in the slideway by manually adjusting the bolt to achieve left and right position adjustment of the support plate.

[0011] Furthermore, the adjusting bolt is connected to the backing plate through threads, thereby ensuring the stability and precise adjustment of the backing plate position.

[0012] Furthermore, the length of the first sliding plate is longer than that of the second sliding plate, and two supporting plates are arranged on the first sliding plate, and one supporting plate is arranged on the second sliding plate.

[0013] Furthermore, the shape of the support plate matches the contact surface of the dummy cage to optimize the contact area and improve the accuracy of the measurement.

[0014] Furthermore, the bottom plate, the first vertical plate, the second vertical plate and the sliding plate are all made of steel to ensure the durability and stability of the device.

[0015] Furthermore, it also includes a limiting mechanism, which is arranged on the guide shaft and is used to limit the sliding range of the sliding plate to prevent excessive sliding from damaging the device or affecting the measurement.

[0016] Furthermore, an interference fit is adopted between the openings on the first vertical plate and the second vertical plate and the corresponding guide shafts to ensure that the first group of guide shafts and the second group of guide shafts are firmly installed and maintain parallelism.

[0017] Compared with the prior art, the utility model has beneficial effects.

[0018] The utility model can be used as a measurement auxiliary tool, and can be combined with measuring tools such as a tape measure to calibrate the size of a crystallizer dummy cage before use, so as to screen the crystallizer dummy cages with sizes meeting the requirements and put them into use, thereby improving the measurement accuracy and efficiency.

[0019] The utility model has a simple structure and is easy to operate, can significantly improve the verification efficiency and accuracy, reduce production accidents caused by deviations in the size of the ingot cage, and meet the strict requirements of the continuous steel casting process.

[0035] b) One side of the dummy cage is placed close to the first vertical plate 2, and the other side is placed close to the second vertical plate 3, and then the sliding plate is pushed to make the support plate 10 close to both sides of the dummy cage.

[0036] c) Adjust the position of the support plate 10 as needed to ensure that it fits tightly with the starter cage body and can be used for starter cages of different lengths.

[0037] d) Use a tape measure to measure the distance between the inner side of the vertical plate and the corresponding support plate 10 to determine the outer contour size of the ingot cage.

[0038] Embodiment 1: The length of the first sliding plate 4 is longer than that of the second sliding plate 5, and two supporting plates 10 are provided on the first sliding plate 4, and one supporting plate 10 is provided on the second sliding plate 5. The shape of the supporting plate 10 matches the contact surface of the dummy cage to optimize the contact area and improve the accuracy of the measurement.
