Description

Technical Field

[0001] The utility model relates to the technical field of steel billet processing, in particular to a novel device for removing flanging on the surface of a steel billet. Background Art

[0002] The raw materials used in the bar and wire production workshop of steel enterprises are rectangular billets, which are produced by continuous casting in the steelmaking workshop and cut into the length required by the steel rolling workshop by a flame cutting machine. Because flame cutting after continuous casting is dynamic cutting, the cut billet section is often accompanied by cutting nodules. If the cutting nodules attached to the bottom of the billet end face are not removed, it is very easy to cause the risk of foreign matter being pressed in during rolling.

[0003] In the prior art, when flanging the surface of a steel billet is performed, a scraper is usually used to scrape the cutting tumor or a milling cutter is used to mill the end face of the steel billet. In this process, due to the hard contact, the tool wear is relatively serious, and the tool usually needs to be replaced frequently. In particular, when the extended handle end of the tool is longer, the contact area between the blade and the surface of the steel billet is larger, which causes the blade to be easily deformed and broken under stress. For operators, working under this condition poses a safety hazard.

[0004] The utility model is a novel device for removing the flanging of the steel billet surface developed to solve the above problems, thereby reducing the single contact area between the blade and the steel billet surface, increasing the cutting force and the effect of removing the flanging of the steel billet surface.
