[0001] The utility model relates to the field of slag removal equipment, in particular to an auxiliary dephosphorization device for a dephosphorization machine. Background Art

[0002] At present, in the process flow of the medium and large bar production line, the steel billet heated to the process temperature must pass through a descaling device before entering the rolling mill for rolling, so as to remove a layer of iron oxide generated on the surface of the steel billet during the heating process.

[0003] The current descaling method is high-pressure water descaling, in which high-pressure water hits the iron oxide scale on the surface of the steel billet through a nozzle, breaking it up and then peeling it off.

[0004] However, for special steel types containing Ni, this method cannot completely remove the surface oxide scale, resulting in defects such as warping and wiredrawing on the steel surface after rolling. In mild cases, manual cleaning is required, increasing labor and finishing costs; in severe cases, the steel defects exceed the size standard and are judged scrap.

[0031] Specifically, the auxiliary dephosphorization device disclosed in the utility model is arranged at the feed port 2 of the dephosphorization machine; it mainly includes a dephosphorization mechanism 3 arranged at the edge of the feed port 2, and the dephosphorization mechanism 3 is mainly used to scrape off the iron oxide scale on the rod. In actual arrangement, the dephosphorization mechanism 3 is required to be connected to the machine body 1 through a fastening mechanism 4; there are various fastening methods, as long as the dephosphorization mechanism 3 can be installed and fixed on the dephosphorization machine.

[0032] Meanwhile, the dephosphorization mechanism 3 in the present invention comprises a plurality of dephosphorization parts 31; in the present invention, the dephosphorization part 31 has a columnar structure; the end of the subsequent dephosphorization part 31 directly acts on the rod material to scrape off the iron oxide scale on the rod material.

[0033] Meanwhile, in the present invention, a plurality of the dephosphorization components 31 are arranged at the edge of the feed port 2; such an arrangement can perform a scraping operation on the rods entering the dephosphorization components 31 from the feed port 2, thereby achieving an iron oxide scale deslagging operation on the rods.

[0034] Furthermore, in the utility model, the plurality of dephosphorization components 31 are evenly distributed along the circumference of the feed port 2; each dephosphorization component 31 extends from the edge of the feed port 2 to the center of the feed port 2; such a configuration enables the dephosphorization component 31 to be equivalent to reducing the opening of the feed port 2, thereby facilitating the contact between the dephosphorization component 31 and the rod material, thereby better realizing the subsequent scraping operation.

[0035] Furthermore, in the present invention, each of the dephosphorization components 31 is a steel wire rope; the provision of the steel wire rope facilitates the subsequent scraping operation.

[0036] Furthermore, the steel wire ropes described in the utility model are all wound together by a plurality of single steel wire ropes; the structural strength of the steel wire ropes is ensured by winding and using a plurality of single steel wire ropes, and at the same time, in the utility model, a plurality of single steel wire ropes are fastened together at one end close to the machine body 1 and are scattered at the end away from the machine body 1; such a setting can increase the contact area between the steel wire rope and the rod material and optimize the slag removal operation.
