[0001] This utility model relates to the technical field of hot rolling equipment for steel strip, specifically, to a hot rolling equipment for corrosion-resistant steel strip. Background Technology

[0002] Hot rolling mills for corrosion-resistant strip steel are commonly used to produce steel with excellent corrosion resistance, and are widely applied in construction, transportation, and chemical industries. In terms of background technology, hot rolling equipment includes a heating furnace, rolling mill, and cooling system, which processes steel billets into strip steel through a series of rolling processes under controlled temperature and pressure conditions. To improve corrosion resistance, steel grades containing alloying elements such as chromium and nickel are used in the production process, while rolling parameters, such as rolling temperature, speed, and cooling rate, are optimized to ensure the uniformity and corrosion resistance of the strip steel.

[0003] According to a public disclosure of a pickling device for surface treatment of steel strip (Publication No.: CN 220788814 U), it includes a pickling body, a steel strip conveying pickling unit, and a slag removal and acid control unit. A rectangular hole is opened on the upper surface of the pickling body, and the rectangular hole extends into the pickling body. A fixing plate is fixedly connected in the rectangular hole. Pickling liquid is provided inside the pickling body. A feed hole is opened on the left side surface of the pickling body, and a discharge hole is opened on the right side surface of the pickling body. The feed hole and the discharge hole extend into the pickling body respectively.

[0004] However, in the above design, after the strip is formed, there are still impurities such as iron on the surface of the strip, which makes it unable to meet the sales standards and needs to be improved. Utility Model Content

A rapid pickling mechanism 5 is provided inside the machine body 1. The rapid pickling mechanism 5 includes a fixing plate 51, which is fixedly connected to the inner wall of the machine body 1. A motor 52 passes through the top of the fixing plate 51. A rotating shaft 53 is fixedly connected to the end of the output shaft of the motor 52. A transmission gear 55 is fixedly connected to the circumferential surface of the rotating shaft 53. An opening is provided on the inner wall of the machine body 1. A slide groove 54 has a rack 56 slidably connected to its inner wall. A connecting spring 57 is fixedly connected to one side of the rack 56. A hollow block 58 is fixedly connected to the bottom of the rack 56. A sliding block 59 is slidably connected to the inner wall of the hollow block 58. A connecting shaft 511 is fixedly connected to the front side of the sliding block 59. A roller 512 is fixedly connected to the circumferential surface of the connecting shaft 511. A tension spring 510 is fixedly connected to the top of the sliding block 59, and the end of the tension spring 510 away from the sliding block 59 is fixedly connected to the top of the inner wall of the hollow block 58.

[0028] A fixing block 513 is fixedly connected to the circumferential surface of the connecting shaft 511. A contact plate 514 is fixedly connected to the bottom of the fixing block 513. A support bracket 7 is fixedly connected to the bottom of the machine body 1. A conveying assembly 4 is provided on the inner side wall of the machine body 1. A rectangular plate 8 is fixedly connected to the side of the machine body 1. A fixing frame 9 is fixedly connected to the bottom of the rectangular plate 8. A forging box 10 is fixedly connected to the top of the rectangular plate 8. A connecting frame 11 is fixedly connected to the top of the rectangular plate 8. An indirect forging assembly 13 is provided on the top of the inner wall of the connecting frame 11. A cooling assembly 12 is provided on the top of the connecting frame 11. The design of the contact plate 514 is conducive to better removal of impurities from the strip steel.

[0029] The transmission gear 55 is set as a half gear, and the transmission gear 55 meshes with the rack 56. The side section of the hollow block 58 is set as concave. When the transmission gear 55 meshes with the rack 56, it drives the rack 56 to move. When the transmission gear 55 no longer meshes with the rack 56, the connecting spring 57 drives the rack 56 to reset.

[0030] Two sliding blocks 59 are provided and are symmetrical to each other along the vertical central axis at the top of the inner wall of the hollow block 58. The motor 52 passes through the top of the fixing plate 51 and is fixedly connected to the fixing plate 51. The above design is conducive to removing impurities from the upper and lower surfaces of the strip steel.

[0031] The initial state of the connecting spring 57 is set to a relaxed state, and the side section of the contact plate 514 is set to an arc shape.

[0032] In this embodiment, the worker first places the forging material into the forging box 10, then activates the indirect forging assembly 13 located at the bottom of the inner wall of the connecting frame 11 to forge the material. Next, the worker activates the cooling assembly 12 located at the top of the connecting frame 11 to cool the forged parts. When the steel strip is formed and undergoing pickling, the worker places the steel strip on the circumferential surface of the unwinding assembly 2, then pulls the steel strip to contact the roller 512 rotating on the circumferential surface of the connecting shaft 511. After the steel strip contacts the roller 512, it contacts the lower half of the conveying assembly 4 located on the inner side wall of the machine body 1. At this time, the worker continuously pulls the steel strip to wind it around the circumferential surface of the winding assembly 3. After winding is complete, the worker pours pickling liquid into the machine body 1 and simultaneously activates the winding assembly 3 to begin winding the steel strip. During the pickling process of the steel strip, the worker activates the electric motor that is fixed through the top of the fixed plate 51. Machine 52 drives the rotating shaft 53 fixed at the end of the output shaft to rotate. The rotation of the rotating shaft 53 drives the transmission gear 55 fixed on the circumferential surface to rotate. At the same time, it drives the meshing rack 56 to slide on the inner wall of the slide groove 54. When the rack 56 slides, it drives the connecting spring 57 fixed on one side to be in a stretched state. When the rack 56 moves, it drives the hollow block 58 fixed at the bottom, which in turn drives the sliding block 59 sliding on the inner wall to move. The movement of the sliding block 59 drives the connecting shaft 511 fixed on the front side to move. At the same time, it drives the roller 512 rotating on the circumferential surface to move up and down on the steel belt. When the roller 512 moves, it is pushed and rotates. When the connecting shaft 511 moves, it drives the fixed block 513 fixed on the circumferential surface to move. The movement of the fixed block 513 drives the contact plate 514 fixed at the bottom to clean the impurities on the upper and lower surfaces of the steel belt again.

A second sprocket 64 is fixedly connected to the circumferential surface of the fixed shaft 63. A chain 65 is provided on the circumferential surface of the first sprocket 61. When the first sprocket 61 rotates, it drives the meshing chain 65 to rotate. When the chain 65 moves, it drives the meshing second sprocket 64 to rotate.

[0035] A turntable 66 is fixedly connected to the circumferential surface of the fixed shaft 63, and a fan blade 67 is fixedly connected to the circumferential surface of the turntable 66. The above design is beneficial to stirring the pickling solution during the pickling process and to prevent precipitation.

[0037] The support legs 7 are arranged in several units and are symmetrical about each other along the vertical central axis at the bottom of the body 1. This design helps to enhance the stability of the body 1 during operation.

[0038] In this embodiment, when the rotating shaft 53 rotates, it drives the first sprocket 61 fixed on the circumferential surface to rotate, and at the same time drives the intermeshing chain 65 to move. The movement of the chain 65 drives the intermeshing second sprocket 64 to rotate.
