Description

Technical Field

[0001] This utility model relates to the technical field of slag removal devices, specifically to an oxygen lance slag removal device. Background Technology

[0002] The oxygen lance is a crucial piece of equipment in modern steelmaking, primarily used in the oxygen blowing stage of converter steelmaking. Its core function is to achieve decarburization, temperature increase, impurity removal, and homogenization of the molten metal through a high-speed oxygen jet reacting with the molten metal in the pool. An oxygen lance typically consists of a body, a nozzle, and a cooling system. The nozzle is designed with multiple nozzles to ensure stable, supersonic oxygen injection, penetrating the slag layer and effectively agitating the molten steel. To ensure stable operation under extreme high-temperature environments, the oxygen lance employs a high-pressure circulating water cooling system to prevent burn-out. Furthermore, the lifting mechanism and control system of the oxygen lance require precise adjustment of the blowing height and oxygen flow rate to adapt to the needs of different stages of smelting. As the "heart" of converter steelmaking, the performance of the oxygen lance directly affects steel quality, smelting efficiency, and production costs, making it an indispensable core piece of equipment for the steel industry's progress towards high efficiency and automation.

[0003] However, during the use of the oxygen lance, it became unusable due to severe residue buildup, and the oxygen lance nozzle was far from reaching its service life. This resulted in the waste of some oxygen lance parts and the consumption of a large amount of manpower for residue removal, indicating certain drawbacks.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0016] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0017] Example 1: like Figures 1 to 4 As shown, an embodiment of this utility model provides an oxygen lance slag removal device, including a mounting base 1, an adjusting frame 2, an angle adjusting cylinder 3, a hydraulic impact head 4, and a positioning component 5.

[0018] Specifically, the adjustment frame 2 is rotatably mounted on the mounting base 1, and the bottom end of the adjustment frame 2 is rotatably connected to the mounting base 1 via a rotating shaft 8.

[0019] The angle adjustment cylinder 3 is movably disposed between the adjustment frame 2 and the mounting base 1, and the angle adjustment cylinder 3 is used to adjust the tilt angle of the adjustment frame 2.

[0020] The hydraulic impact head 4 is slidably mounted on the adjusting frame 2 via the guide rail 6, and the hydraulic impact head 4 slides along the length direction of the adjusting frame 2. A displacement telescopic rod 7 is provided between the hydraulic impact head 4 and the bottom end of the adjusting frame 2, and the displacement telescopic rod 7 is used to push the hydraulic impact head 4 to slide along the guide rail 6.

[0021] The positioning element 5 is disposed on the adjusting frame 2, and the positioning element 5 positions the hydraulic impact head 4 by clamping the oxygen lance.

[0022] In this embodiment, when slag removal is required for the oxygen lance, the angle adjusting cylinder 3 drives the adjusting frame 2 to rotate to a position perpendicular to the mounting base 1. Simultaneously, the hydraulic impact head 4 slides to its highest position, preparing for the next slag removal operation. Once the adjusting frame 2 is perpendicular to the mounting base 1, the positioning component 5 activates, clamping and fixing the oxygen lance to further secure and position the adjusting frame 2, thus completing the on-site setup of the slag removal device. During the slag removal operation, the hydraulic impact head 4 uses its tip to vibrate and impact the slag deposits on the oxygen lance, breaking up the slag adhering to the outside of the oxygen lance and separating it from the lance, thus achieving slag removal. Compared to manual slag removal, this slag removal device can automatically and quickly perform the slag removal operation, greatly improving the efficiency of slag removal.

[0023] In one specific embodiment, two angle adjustment cylinders 3 are provided, and the two angle adjustment cylinders 3 are symmetrically distributed on the mounting base 1. The two angle adjustment cylinders 3 extend and retract synchronously to adjust the tilt angle of the adjustment frame 2.

[0024] Furthermore, the positioning component 5 includes a positioning gripper 9, a transmission gear 10, a drive rack 11, and a rotating telescopic rod 12.

[0025] Specifically, there are two symmetrically arranged positioning grippers 9, and each of the two positioning grippers 9 has a transmission shaft 8 fixedly installed at its end, and the transmission shaft 8 is rotatably installed on the adjusting frame 2.

[0026] The transmission gear 10 is fixedly mounted on the transmission shaft 8, and the transmission gear 10 is located at the end of the transmission shaft 8 opposite to the positioning gripper 9.

[0027] The drive rack 11 is movably mounted on the adjusting frame 2, and the drive rack 11 is meshed with the two transmission gears 10.

[0028] The rotating telescopic rod 12 is fixedly installed on the adjusting frame 2, and the output end of the rotating telescopic rod 12 is fixedly connected to the driving rack 11.

[0029] In this embodiment, when it is necessary to fix and position the adjusting frame 2, the rotating telescopic rod 12 drives the drive rack 11 to move linearly. During the linear movement of the drive rack 11, since the drive rack 11 is meshed with the two transmission gears 10, the drive rack 11 can drive the two transmission gears 10 to rotate, which in turn drives the two positioning jaws 9 to rotate through the transmission shaft 8. After the two positioning jaws 9 close, the two jaws clamp and fix them on the outer wall of the oxygen lance, completing the fixing and positioning of the adjusting frame 2.

[0030] In one specific embodiment, the positioning claw 9 is L-shaped, and a positioning clamping groove 13 is formed on the positioning claw 9. The positioning clamping groove 13 is semi-circular, and when the two positioning claws 9 are closed, the two positioning clamping grooves 13 form a circle and clamp onto the oxygen lance. After the two positioning claws 9 are closed, the outer wall of the oxygen lance is in close contact with the inner wall of the two positioning clamping grooves 13, thereby achieving the clamping and fixing of the positioning claws 9 on the outer wall of the oxygen lance.

[0031] To reduce the impact of vibration from the hydraulic impact head 4 on the oxygen lance during operation, a vibration damping pad is fixedly installed on the inner wall of the positioning and clamping groove 13. The vibration damping pad 14 can reduce vibration transmission and reduce the wear caused by vibration on the oxygen lance.

[0032] Example 2: Based on Embodiment 1, an auxiliary telescopic rod 15 is provided between the mounting base 1 and the adjustment frame 2, and the auxiliary telescopic rod 15 is located between two angle adjustment cylinders 3 to improve the stability of the rotation angle adjustment of the adjustment frame 2.

[0033] Unlike existing technologies, this utility model has at least the following beneficial effects: This invention utilizes an angle-adjusting cylinder to initially establish the working environment of the hydraulic impact head, while simultaneously using positioning components to fix and position the hydraulic impact head and adjustment frame. This enables rapid and effective impact removal of slag on the oxygen lance, featuring a simple structure and convenient operation.

[0034] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
