Description

Technical Field

[0001] The utility model relates to the field of steel preparation, in particular to a processing device for preparing high-strength steel. Background Art

[0002] During the steel production process, a layer of oxide scale forms on the steel surface. This oxide scale is mainly composed of iron oxides, which can have adverse effects on the surface quality of the steel, such as reducing the corrosion resistance of the steel and affecting the adhesion of the coating.

[0003] High-strength steel pipes or steel bars produced by continuous casting usually use high-pressure water jets to impact and flush the steel surface to remove the oxide scale. This dephosphorization method not only wastes water but also causes subsequent rust on the steel. Utility Model Content

[0004] To this end, the utility model provides a processing device for preparing high-strength steel, which is used to achieve efficient phosphorus removal of high-strength steel pipes and bars in a water-free environment, so as to overcome the waste and pollution caused by the high-pressure water removal method in the existing technology.

[0008] The second transmission device is arranged at the output end of the dephosphorization part, and includes a second base frame and a second conveyor belt arranged above the second base frame.

[0009] Furthermore, the first dephosphorization unit includes a plurality of scrapers arranged on the inner wall of the dephosphorization barrel near the end of the first transmission device and distributed at equal angles along the central axis of the dephosphorization barrel.

[0011] Furthermore, the ratchet pawl is made of high manganese steel.

[0012] Furthermore, the number of the phosphorus scrapers is 3-5.

[0013] Furthermore, the second dephosphorization unit includes a plurality of phosphorus brushes arranged on the inner wall of the dephosphorization barrel near the end of the second transmission device and distributed at equal angles along the central axis of the dephosphorization barrel.

[0031] The present invention provides a processing device for preparing high-strength steel, comprising:

[0032] A first transmission device includes a first base frame 11 and a first conveyor belt 12 arranged above the first base frame 11;

[0033] The dephosphorization unit is provided at the output end of the first transmission device and includes a bracket 21, a rolling cavity 22 extending through the bracket 21, a plurality of support wheels 23 disposed within the rolling cavity 22, a dephosphorization barrel 24 coaxially disposed with the rolling cavity 22, the outer wall of the dephosphorization barrel 24 being tangential to each of the support wheels 23, a first dephosphorization unit for pre-dephosphorization and a second dephosphorization unit for fine dephosphorization disposed on the inner wall of the dephosphorization barrel 24, and a power motor 27 disposed above the bracket 21 for driving the dephosphorization barrel 24 to rotate. A belt 28 drives the power motor 27 and the dephosphorization barrel 24.

[0034] The second transmission device is provided at the output end of the dephosphorization section and includes a second chassis 32 and a second conveyor belt 33 provided above the second chassis 32 .

[0035] Specifically, the first transmission belt 12 and the second conveyor belt 33 are, for example, steel chain conveyor belts. The specific size of the steel chain conveyor belts is not limited and can be designed according to the size of the steel in the actual production process. The specific strength of the steel chain conveyor belts is not limited and only needs to be able to bear the weight of the steel in the actual production process.

[0036] Specifically, the support wheel 23 is, for example, a rolling bearing. It can be understood that the inner ring of the rolling bearing is fixed to the bracket, and the outer ring of the rolling bearing is tangent to the outer wall of the rolling cavity 22 and the dephosphorization barrel 24 respectively.

[0037] Specifically, the first dephosphorization unit includes a plurality of phosphorus scrapers 251 arranged on the inner wall of the dephosphorization barrel 24 near the end of the first transmission device and distributed at equal angles along the central axis of the dephosphorization barrel 24 .

[0038] Specifically, the scraper 251 includes a ratchet pawl 2510, one end of which is hinged to the inner wall of the dephosphorization barrel 24 through a hinge pin 241, and a claw knife 2511 is provided at the other end of the ratchet pawl 2510. A first loading spring 2512 is provided on the back of the ratchet pawl 2510 near the end of the claw knife 2511, and the other end of the first loading spring 2512 is connected to the inner wall of the dephosphorization barrel 24. It can be understood that the claw knife of the ratchet pawl 2510 is attached to the outer wall of the pipe or rod, and as the power motor 27 drives the dephosphorization barrel 24 to rotate, the rotation direction is Figure 2The clockwise direction of the cross section drives the claw knife 2511 of the ratchet pawl 2510 to scrape the outer wall of the pipe or rod. When encountering resistance during the scraping process, the ratchet pawl 2510 will bounce up, and then quickly reset under the action of the first loading spring 2512, so that the impact generated during the bounce and reset process further increases the dephosphorization effect.

[0039] Specifically, the ratchet pawl 2510 is made of high manganese steel. It is understandable that high manganese steel has high wear resistance and impact resistance.

[0040] Specifically, the number of the phosphorus scrapers 251 is 3-5, and in this embodiment, the number of the phosphorus scrapers is 4.

[0041] Specifically, the second dephosphorization unit includes a plurality of phosphorus brushes 2610 arranged on the inner wall of the dephosphorization barrel near the end of the second transmission device and distributed at equal angles along the central axis of the dephosphorization barrel.

[0042] Specifically, the phosphorus brush device 2610 includes a phosphorus brush plate 2610, one end of which is hinged to the inner wall of the dephosphorization barrel 24 through a hinge pin 241, and the other end of the phosphorus brush plate 2610 is provided with a brush head. A second loading spring 2613 is provided on the back of the phosphorus brush plate 2610 near the brush head end, and the other end of the second loading spring 2613 is connected to the inner wall of the dephosphorization barrel 24.

[0043] Specifically, the brush head is a wire brush 26121; the working surface of the wire brush 26121 is a curved surface. It can be understood that the wire brush 26121 with a curved working surface has a high degree of compatibility with the surface of the pipe and the rod.

[0044] Specifically, the brush head is sandpaper 26122; a rubber pad 26123 is provided between the sandpaper and the brush plate, and the rubber pad 26123 can increase the degree of fit between the sandpaper and the surface of the pipe and rod.

[0045] Specifically, in this embodiment, three support wheels 23 are provided and the support wheels 23 are distributed at equal angles along the central axis of the dephosphorization barrel 24 , which can improve the rotation stability of the dephosphorization barrel 24 .

[0046] For those skilled in the art, according to the concept of the embodiments of the present invention, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
