Description

Technical Field

[0001] The utility model relates to the field of steel processing equipment, in particular to an automatic rejecting device for rolled steel with double length tail steel. Background Art

[0002] Steel rolling is a vital link in the steel production process. Steel rolling refers to the process of processing steel billets through rolling mills to transform them into the required shape and size. "Double-length tail steel" may refer to the oversized tail steel produced during the rolling process. The steel rolling process in steel production usually includes stages such as rough rolling, finishing rolling and shaping. In this process, the billet will undergo multiple rolling to achieve the required size and shape. In some cases, due to factors such as process parameters or equipment adjustments, some steel may be oversized and form tail steel. Dealing with double-length tail steel usually requires different measures according to the actual situation, such as adjusting the rolling mill parameters, reheating and re-rolling, cutting or heat treatment, etc., to ensure that the final steel products that meet the standards are produced.

[0003] In the past steel rolling production process, tail steel was a problem that could not be ignored. Since tail steel is produced during the shearing process, its quantity is usually not accurately controlled and it is easy to be confused with qualified steel. This leads to a situation where the tail steel is not effectively removed, but is sheared together with other undamaged steel. This practice not only causes huge waste, but also reduces the quality of the finished product, greatly reducing the yield rate. The existence of tail steel will have a great impact on the production process of steel rolling. First, the presence of tail steel will increase the impurity content in the production process, thereby affecting the normal rolling. Secondly, the hardness and toughness of the tail steel are different from those of qualified steel, which will affect the subsequent rolling and cooling process, and may cause cracks, deformation and other problems in the product. These problems will affect the final performance of the product and reduce the yield rate.

[0004] Therefore, it is necessary to provide a new automatic removal device for rolled steel with double length tail steel to solve the above technical problems. Utility Model Content
