[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0015] See attached document Figure 1 This embodiment provides a device for cleaning the iron oxide layer on both sides of a steel billet, comprising two sets of cleaning mechanisms symmetrically arranged in the installation areas 9 on both sides of the steel billet 3. Each cleaning mechanism includes a scraper block 2, a wire rope 4, a stroke adjustment seat 5, an adjusting screw rod 6, a bracket 7, and a base 8. The base 8 is mounted on a roller beam 11, and the bracket 7 is mounted on the base 8. The stroke adjustment seat 5 is mounted on the top of the bracket 7. The stroke adjustment seat 5 has a wire rope slide inside, and two wire ropes 4 are arranged parallel to each other in the wire rope slide. Each wire rope is matched with three adjusting screw rods 6 arranged side by side for positioning. The adjusting screw rods 6 pass through holes in the side wall of the stroke adjustment seat 5 to position the wire rope 4 in the wire rope slide. Both ends of the wire rope 4 extend out of the outside of the stroke adjustment seat 5. A scraper block 2 is provided at the end of the wire rope 4 adjacent to the steel billet 3. Each wire rope 4 is fixed in the scraper block 2 by its own screw rod 1.
[0016] In this embodiment, a support frame 7 and a base 8 are fabricated using steel structures, and a stroke adjustment seat 5 is manufactured and welded to the support frame 7 and the base 8. A scraper block 2 is fabricated, and a steel wire rope 4 is installed in the hole of the scraper block 2 and tightened by a screw 1. Two steel wire ropes 4 are threaded into the holes (steel wire rope tracks) of the stroke adjustment seat 5 and tightened by adjusting the top screw 6.
[0017] This utility model is a centrally symmetrical structure for cleaning the iron oxide layer on both sides of a steel billet. It includes two sets of identical cleaning mechanisms, symmetrically arranged on both sides of the steel billet 3 in the width direction. By turning and adjusting the top screw 6, the wire rope 4 is loosened within the wire rope slide of the stroke adjustment seat 5. By moving the wire rope 4 on both sides to the position of the stroke adjustment seat 5, the contact between the scraper block 2 and the steel billet 3 is adjusted. By adjusting the distance deviation between the upper and lower wire ropes 4, the perpendicularity between the scraper block 2 and the side of the steel billet 3 is adjusted. According to field test verification, in order to ensure effective removal of the iron oxide layer on both sides of the steel billet 3, the distance between the scraper blocks 2 on the two sets of cleaning mechanisms is adjusted to be less than the width of the steel billet 3 by 10mm, which constitutes the yield prestressed elastic force of the wire rope, so that the scraper blocks 2 are in close contact with both sides of the steel billet 3.
[0018] See attached document Figure 2 The roller beam 11 is equipped with multiple roller assemblies 10, and two sets of cleaning mechanisms are installed on it. Figure 2 As shown in installation area 9, the base 8 of the cleaning device is installed and secured to the roller beam 11 by bolts. Furthermore, the cleaning device is not limited to the location in installation area 9; it can be installed at any position among the multiple roller assemblies 10.
