Description

Technical Field

[0001] The utility model belongs to the technical field of No. 1 shear sampling in a bar rolling production process, in particular to a sampling device for quality control in the intermediate process of bar rolling. Background Art

[0002] At present, in order to ensure the size and surface quality of finished round steel during the production process of bars, it is necessary to regularly cut and sample the steel heads (mainly the red steel after No. 1 shearing) during the rolling process to check whether the red steel size meets the requirements and whether there are defects on the red steel surface. In the traditional production process, sampling mainly relies on workers to hook out the steel heads using tools such as iron hooks. Later, the guide rail base was fixed and the sampling trolley was installed for sampling. This device reduced the personal safety hazards during the sampling process. However, due to the limited area, the guide rails and trolleys could not move freely. When a steel pile accident occurred, it seriously affected the handling of the accident and increased the labor intensity and risk factor of the workers. At the same time, after the sampling is completed, the temperature of the steel head drops quickly, and it needs to be reheated and then forged to detect its surface quality. Only after it is qualified can it be continuously produced, which seriously reduces the operating rate. At the same time, the sampling steel head falling off the trolley is likely to cause surface scratches, affecting the results of quality judgment. In order to solve these problems and improve the flexibility, safety and accuracy of sampling, a trackless and flexible intermediate process quality control sampling device is designed.
