Description

Technical Field

[0001] This invention belongs to the field of copper smelting technology, and specifically relates to a converter adjustment method. Background Technology

[0002] During smelting operations, converters need to rotate back and forth within a certain angle range. Due to uneven wear of the rollers and support rollers, it is normal for the furnace body to experience slight jumping or axial movement during rotation. However, when the furnace body moves significantly in one direction for an extended period, adjustments are necessary. Existing furnace adjustment methods are cumbersome and time-consuming, severely impacting equipment maintenance efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a highly efficient converter adjustment method.

[0004] To achieve the above objectives, the technical solution adopted by this invention is as follows: a converter adjustment method, wherein rolling rings are respectively provided at both ends of the furnace body, the bottom of the rolling rings are in rolling engagement with the support rollers, the support rollers are rotatably mounted on the support roller brackets, the drive end support rollers are finely adjusted so that the wheel core of the drive end support roller is parallel to the shaft core of the drive end rolling ring, and the top wheel surface of the drive end support roller matches the outer circumferential contour of the drive end rolling ring; the free end support roller brackets are adjusted so that the wheel core of the free end support roller is arranged at an angle with the shaft core of the free end rolling ring, while simultaneously driving the furnace body to rotate, the furnace body moves in its axial direction, and the distance between the end faces of the drive end rolling rings and each drive end support roller away from the drive mechanism is observed. When the difference in the distance between each end face is less than a limited value △d u At this time, the shaft core of the drive end rolling ring is adjusted to the design position, completing the adjustment of the furnace body posture.

[0005] Compared with the prior art, the present invention has the following technical effects: after finely adjusting the drive end support roller to the design position according to the ring surface of the drive end roller, the furnace body can be quickly debugged by finely adjusting the furnace body posture, which can effectively improve the maintenance and debugging efficiency of the converter, thereby ensuring the stable and reliable operation of the furnace body.

[0014] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0015] The converter to be adjusted in this embodiment is shown in the attached figure. Figure 1-3 As shown, the furnace body 11 is mounted on the base 10. Rolling rings 12 are provided at both ends of the furnace body 11. The bottom of the rolling rings 12 rolls in engagement with a support roller 20, which is rotatably mounted on a support roller bracket 23. A gear ring 14 is fixedly mounted at one end of the furnace body 11. A drive mechanism 13, which engages with the gear ring 14, is provided on the base 10. The drive mechanism 13 drives the furnace body 11 to rotate around the axis of the gear ring 14. For ease of description, the rolling ring 12 adjacent to the gear ring 14 is designated as the drive end rolling ring 12a, and the other rolling ring 12 is designated as the free end rolling ring 12b. Similarly, the support roller 20 supporting the drive end rolling ring 12a is designated as the drive end support roller 20a, and the support roller 20 supporting the free end rolling ring 12b is designated as the free end support roller 20b.

[0016] A converter adjustment method involves first fine-tuning the drive-end support roller 20a so that its wheel core is parallel to the shaft core of the drive-end rolling ring 12a, and its top surface aligns with the outer periphery of the drive-end rolling ring 12a. Then, the free-end support roller bracket 23b is adjusted so that the wheel core of the free-end support roller 20b is angled with the shaft core of the free-end rolling ring 12b, simultaneously driving the furnace body 11 to rotate and allowing it to move axially. (See attached diagram.) Figure 5 Observe the distance d between the end face of the drive end rolling ring 12a and the end face of each drive end support roller 20a away from the drive mechanism 13. When the difference between the distances of each end face is less than the limit value Δd uAt this time, the shaft of the drive end roller 12a is adjusted to the designed position, completing the adjustment of the furnace body 11's posture. Specifically, the drive end support roller 20a is first fine-tuned to the designed position based on the drive end roller 12a, and then the free end support roller 20b is adjusted to adjust the furnace body 11's posture. The distance d between the end face of the drive end roller 12a and the end face of the drive end support roller 20a is used to determine whether the furnace body 11 has been adjusted to the designed position. (Appendix) Figure 5 This is an enlarged schematic diagram showing the engagement state of the drive-end rolling ring 12a and a drive-end support roller 20a. The distance between their end faces furthest from the drive mechanism 13 is the distance d marked in the diagram. Let w t w is the wheel surface width of the drive end support roller 20a. g The width of the drive end rolling ring 12a is given by the distance d between the end face of the drive end rolling ring 12a and the end face of the drive end support roller 20a away from the drive mechanism 13. t- w g To prevent the furnace body 11 from falling off the support roller 20, see attached... Figure 5 As shown, the drive-end support roller 20a has radially outwardly protruding wheel edges 24 at both ends. When the axial displacement of the furnace body 11 is too large, the wheel edges 24 can abut against the end face of the drive-end rolling ring 12a. In specific implementation, the mating area between the drive-end rolling ring 12a and the drive-end support roller 20a is exposed, and the end face distance d is easy to measure and obtain, facilitating the operation of the converter for the operators.

[0017] Furthermore, during the converter operation, the distance between the end face of the drive end support roller 20a and the end face of the drive end rolling ring 12a can be monitored. When the difference between the end face of the drive end rolling ring 12a and the end face of the drive end support roller 20a exceeds the limit value △d, the system will detect the difference. u If the deviation exceeds the limit, it indicates that the attitude deflection of the drive end roller 12a and the drive end support roller 20a is causing an alarm for furnace attitude adjustment. After the operators check that the connection between the drive end roller 12a and the furnace body 11, the damage to the surface of the drive end roller 12a, the damage to the surface of the drive end support roller 20a, and the attitude of the drive end support roller 20a are all correct, the furnace attitude can be adjusted according to the aforementioned method to ensure the stable operation of the furnace body 11.

[0018] The adjustment of the free end support roller bracket 23b is as shown in the attached figure. Figure 6 , 7 As shown, the wheel cores of the free-end support rollers 20b symmetrically arranged on both sides of the furnace body 11 are arranged at an included angle. See Appendix Figure 6 When the wheel cores of the free-end support rollers 20b symmetrically arranged on both sides of the furnace body 11 are arranged near the free-end rolling ring 12b, the furnace body 11 is driven to rotate, and the furnace body 11 will move towards the driving end, that is, the furnace body 11 will shift to the right side of the figure; see appendix. Figure 7When the wheel cores of the free end support rollers 20b symmetrically arranged on both sides of the furnace body 11 are arranged near the drive end rolling ring 12a, the furnace body 11 will be driven to rotate, and the furnace body 11 will move towards the drive end, that is, the furnace body 11 will be displaced to the left in the figure.

[0019] As attached Figure 2 As shown, in this embodiment, the support roller 20 includes a high-position roller 21 and a low-position roller 22. The high-position roller 21 and the low-position roller 22 are rotatably mounted on the support roller bracket 23 to form a support roller assembly. The support roller assembly is symmetrically distributed on both sides of the plumb line passing through the axis of the furnace body 11. After the drive-end support roller 20a is finely adjusted, the coplanar plane of the wheel cores of the two drive-end high-position rollers 21a is perpendicular to the plumb line, and the coplanar plane of the wheel cores of the two drive-end low-position rollers 22a is also perpendicular to the plumb line.

[0020] This implementation example is attached. Figure 4 As shown, a limiting wheel 30 is provided on the bottom end face of the free end rolling ring 12b near the drive end. The rotation axis of the limiting wheel 30 is arranged vertically, and the limiting wheel 30 rolls with the end face of the free end rolling ring 12b to restrict the displacement of the free end rolling ring 12b towards the drive end. Furthermore, the limiting wheel 30 is mounted on the base 10 via a linear displacement mechanism, which drives the limiting wheel 30 to move axially along the furnace body 11.

[0021] Let the design distance between the end face of the drive end rolling ring 12a and the end face of the drive end support roller 20a away from the drive mechanism 13 be d. s 0 <d s <w t- w g , where w t w is the wheel surface width of the drive end support roller 20a. g The width of the drive end rolling ring 12a is shown in the attached example. Figure 2 , 3 As shown, baffles 15 are welded to both sides of the rolling ring 12 on the furnace body 11. To ensure the reliable operation of the rolling ring 12 under high-temperature working conditions or after deformation due to long-term use, the distance between the abutting surfaces of the baffles 15 on both sides of the same rolling ring 12 is greater than the width of the rolling ring 12, which is w. g +a, where a is a constant. Then, the limiting value of the end face distance Δd is... u ≥a. In this embodiment, the design value of the end face spacing d s =(w t- w g ) / 2.

[0022] The adjustment of the furnace body 11's posture includes the following steps:

[0023] K1, the distance between the end face of the drive end rolling ring 12a and the end face of the drive end support roller 20a away from the drive mechanism 13 is less than the design value d of the end face distance. s If so, proceed directly to step K2.

[0024] The distance between the end faces of the drive end roller 12a and the drive end support roller 20a, which is furthest from the drive mechanism 13, is greater than the design value d for the end face distance. s At this time, adjust the free end support roller bracket 23b so that the wheel cores of the free end support rollers 20b symmetrically arranged on both sides of the furnace body 11 are at an angle with a larger distance on the side away from the drive mechanism 13 and a smaller distance on the side adjacent to the drive mechanism 13. This drives the furnace body 11 to move towards the free end until the distance between the end face of the drive end rolling ring 12a and the end face of the drive end support roller 20a away from the drive mechanism 13 is less than the designed end face distance d. s Proceed to step K2.

[0025] K2. Adjust the limiting wheel 30 to the designed position, and adjust the free end support roller bracket 23b so that the wheel cores of the free end support rollers 20b symmetrically arranged on both sides of the furnace body 11 form an angle with a smaller distance on the side away from the drive mechanism 13 and a larger distance on the side adjacent to the drive mechanism 13. Drive the furnace body 11 to move towards the drive end. After the end face of the free end rolling ring 12b contacts the limiting wheel 30, monitor the distance between the end face of the drive end rolling ring 12a and the end face of each drive end support roller 20a away from the drive mechanism 13.

[0026] When the difference in the distance between each end face is less than the limit value △d u At this time, the free end support roller bracket 23b is rotated to the designed position so that the wheel core of the free end support roller 20b is parallel to the axis of the free end rolling ring 12b, thus completing the fine adjustment of the furnace body 11 attitude and the converter enters the normal working state.
