Detailed description of the invention
In order to understand the utility model better, explain embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Embodiment 1, composition graphs 1 to Fig. 7, the steel billet dephosphorization apparatus that a kind of small rod production line uses, comprise rollgang 7 before support 1, back shaft 2, scraper plate 5, steel billet, before described steel billet, the neutral position between billet heating furnace and First milling train is located at by rollgang 7, and before described front steel billet, rollgang 7 is connected with support 1 bottom, be connected with roller-way foundation frame bottom support 1, frame upper is provided with back shaft 2, is provided with scraper plate 5 in the centre position of back shaft 2, and scraper plate 5 is around back shaft axis oscillating.After installing, scraper plate 5 is by locating piece 3 under the effect of balancing weight, keeps becoming plumbness with blank traffic direction, and scraper plate 5 is under plumbness freely, and scraper plate 5 bottom surface is lower than steel billet blank upper surface.As scraper plate 5 bottom surface can lower than blank upper surface 30mm to 60mm.
The back shaft 2 at described scraper plate two ends is provided with locating piece 3, and scraper plate 5 regulates the axial location on back shaft 2 by locating piece 3.
Described back shaft two ends are fixed on support 1 by locking nut 4.
Described scraper plate is provided with counterweight 6 upper, higher than the bottom surface of scraper plate bottom described counterweight 6.Described counterweight 6 is connected with the surface of scraper plate 5 along steel billet traffic direction side.Rely on balancing weight to remove blank surface iron scale under gravity, the size of scraper plate 5 pairs of steel billet active forces can be regulated by the size of balancing weight.
