Description

Technical Field

[0001] This utility model relates to a tool for cutting corners on cast billets, belonging to the technical field of continuous casting billet production equipment. Background Technology

[0002] During continuous casting, factors such as improper control of casting temperature and casting speed, slag entrapment, and excessive secondary cooling strength can easily lead to defects such as corner cracks and corner depressions at the corners of the billets. Billets with corner defects can affect the stability of subsequent forging and rolling processes. These defects can usually be removed by corner trimming, improving the quality of the continuously cast billets. Currently, some steel companies use manual methods for corner trimming, employing acetylene torches to remove corner defects. This method is labor-intensive, involves harsh working conditions, has a high risk factor, and produces inconsistent cutting quality, severely impacting the quality of the continuously cast billets and subsequent production. Improvement is urgently needed. Utility Model Content
