Description

Technical Field

[0001] The utility model relates to the technical field of sliding nozzle detection, in particular to an airtightness detection device for the sliding nozzle of a ladle. Background Technique

[0002] The sliding nozzle is a key device for precisely regulating the molten steel flow rate in the continuous casting process. It can accurately control the water flow rate from the ladle to the tundish of the continuous casting, balance the inflowing and outflowing molten steel, making the continuous casting operation easier to control. It is an indispensable part of smelting. As a key device for controlling the molten steel flow rate in the continuous casting process, the airtightness of the sliding nozzle is directly related to whether the molten steel can accurately and stably flow into the tundish. If the airtightness of the sliding nozzle is poor, it may cause molten steel leakage, which not only wastes precious molten steel resources but also may pose serious safety hazards to production equipment and operators.

[0003] After retrieval, the Chinese patent with the application number CN202221188671.1 discloses a variety of detection devices for the sliding nozzle of a ladle. In the actual use of the existing sliding nozzle detection device for the ladle, it is necessary to fix the sliding nozzle and then measure the inner diameter of the sliding nozzle. However, the existing sliding nozzle detection device cannot be applied to the detection of sliding nozzles of different sizes. It may only be able to detect a single-size sliding nozzle in actual use, which will cause inconvenience in the detection of the sliding nozzle. Therefore, by moving the sliding nozzle between two clamping blocks, then opening the first telescopic rod to drive the support plate to move downward, the support plate will drive the sliding rod to move downward, drive the limit block to move downward, drive the clamping block to move downward, and the clamping block will move downward along the inner wall of the fixed box. Then the clamping block will gradually approach, and then achieve the effect of clamping the sliding nozzle, achieving the effect of facilitating the fixation of sliding nozzles of different sizes.

[0004] In the above detection process of the sliding nozzle, it is convenient to clamp the sliding nozzle. However, the above clamping only uses the downward movement of the clamping block to clamp the sliding nozzle, and the clamping effect is relatively weak. Moreover, it is not convenient to tightly clamp the sliding nozzle according to the direction of the clamping point required in the sliding nozzle. At the same time, it is not convenient to adjust the clamping height of the clamping component according to the height of the sliding nozzle of different sizes, which reduces the clamping effect of the clamping component, resulting in easy shaking and displacement of the sliding nozzle during the clamping process, thus causing disengagement from the clamping component, reducing the accuracy and accuracy of the airtightness detection, and being inconvenient for detection.
