Description

Technical Field

[0001] This utility model relates to the field of slag-blocking tools, and in particular to a converter slag-blocking structure. Background Technology

[0002] A large amount of slag is produced during the converter steelmaking process. The slag contains a variety of impurities. If the slag enters the molten steel, it will significantly increase the impurity content in the molten steel. Therefore, slag blocking operation is required to effectively prevent slag from mixing into the molten steel. The common slag blocking tool is the slag blocking plug. Before the steel tapping process begins, the workers will insert the slag blocking plug into the tapping port. When the molten steel flows out, the slag blocking plug can allow the molten steel to pass through smoothly. When the slag flows out, due to its special shape and position at the tapping port, it can effectively prevent the slag from flowing out.

[0003] Currently, existing slag-blocking plugs are directly inserted into the converter taphole during use. When molten steel and slag flow out rapidly or the converter tilts at an excessive angle, the slag-blocking plug is subjected to an upward force, resulting in a gap between the plug and the taphole. At this time, slag will flow into the molten steel through the gap, which will affect the quality of the molten steel. To address this issue, we propose a converter slag-blocking structure. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A converter slag-blocking structure includes a converter body 1, a tapping port 2 connected to the side of the converter body 1, and a connecting ring 3 connected to the end of the tapping port 2. A slag-blocking plug 4 is inserted inside the tapping port 2. A fixing ring 5 is connected to the inner side of the connecting ring 3, and a rotating rod 6 is connected to the inner side of the fixing ring 5 via a bearing. Since the fixing ring 5 and the rotating rod 6 are connected by a bearing, the rotation requirement of the rotating rod 6 can be met. When the slag-blocking plug 4 needs to be inserted, the operator can rotate the baffle 8 to a position offset from the opening of the tapping port 2 to meet the normal insertion requirement of the slag-blocking plug 4. After insertion, the operator... The operator can rotate the baffle 8 180 degrees to position it on the side of the slag plug 4 to block the slag plug 4. A telescopic rod 7 is inserted into the opening of the rotating rod 6, and the other end of the telescopic rod 7 extends into the interior of the converter body 1 and is connected to the baffle 8. The telescopic rod 7 and the baffle 8 are made of high-temperature resistant material, which can meet the requirements for normal use inside the converter body 1. In addition, the insertion interface inside the converter body 1 corresponding to the telescopic rod 7 is provided with a high-temperature resistant sealing component, similar to the graphene material sealing component in the prior art, to ensure the sealing of the telescopic rod 7 when inserted into the converter body 1.

[0024] Furthermore, refer to Figure 3 It can be seen that a moving ring 9 is sleeved on the outer side of the rotating rod 6, and a positioning rod 11 is symmetrically connected to the side of the moving ring 9 near the connecting ring 3. The end of the fixed ring 5 is provided with four sets of positioning grooves that are adapted to the positioning rod 11. The inner side of the moving ring 9 is connected to the first slider 10, and the side of the rotating rod 6 is provided with a slide that is adapted to the first slider 10. Through the cooperation of the moving ring 9 and the positioning rod 11, it is convenient for the operator to limit the rotating rod 6 when it is rotated to a suitable angle. Through the cooperation of the first slider 10 and the slide, the rotating rod 6 can be rotated together with the moving ring 9.

[0025] Furthermore, refer to Figure 5It can be seen that the side of the moving ring 9 is connected to a protruding piece 12, and the outer side of the protruding piece 12 is provided with anti-slip texture. Through the cooperation of the protruding piece 12 and the anti-slip texture, it is easy for the staff to pull and rotate the moving ring 9.

[0026] Furthermore, refer to Figure 4 It can be seen that the rotating rod 6 is connected to the mounting ring 13 on the side away from the connecting ring 3, and the inner wall of the mounting ring 13 is horizontally inserted with a threaded rod 14. The other end of the threaded rod 14 is connected to an abutment plate 15. The inner wall of the mounting ring 13 is connected to a fixing plate 18, and the side of the abutment plate 15 is connected to a guide rod 16. The mounting ring 13 has a moving groove that matches the guide rod 16. The guide rod 16 and the moving groove can guide the abutment plate 15 to effectively prevent the abutment plate 15 from rotating. The mounting ring 13 has a threaded groove that matches the threaded rod 14. By rotating the threaded rod 14, the abutment plate 15 and the outer wall of the telescopic rod 7 can abut against each other. With the fixing plate 18, the telescopic rod 7 can be clamped and positioned to adjust the position of the baffle 8.

[0027] Furthermore, refer to Figure 4 It can be seen that the abutment plate 15 and the fixing plate 18 are set with arc-shaped structures. The inner walls of the fixing plate 18 and the abutment plate 15 are both provided with serrations. Since the abutment plate 15 and the fixing plate 18 are set with arc-shaped structures, the clamping effect on the telescopic rod 7 can be improved. The serrations are not shown in the figure. By setting the serrations, the limiting effect on the telescopic rod 7 can be further guaranteed.

[0028] Furthermore, refer to Figure 5 It can be seen that the end of the telescopic rod 7 is connected to the second slider 19, and the inner wall of the rotating rod 6 is provided with a groove that matches the second slider 19. Through the cooperation between the second slider 19 and the groove, the telescopic rod 7 can be stably moved inside the rotating rod 6.

[0029] Furthermore, refer to Figure 4 It can be seen that one end of the threaded rod 14 is connected to the rotating rod 17, and the other end of the threaded rod 14 is connected to the abutment plate 15 through the bearing. With the setting of the rotating rod 17, it is easy for the operator to rotate the threaded rod 14, so as to effectively improve the convenience of using the device.

[0030] Working Principle: In use, before the steel pouring process begins, the operator inserts the slag-blocking plug 4 into the taphole 2 through the side opening of the converter body 1 using appropriate tools. After inserting the plug 4, the operator first lifts the moving ring 9, causing the positioning rod 11 connected to its side to be pulled out from inside the fixed ring 5. Then, the operator rotates the rotating rod 6, causing the telescopic rod 7 and the baffle 8 to rotate 180 degrees. At this point, the position of the baffle 8 corresponds to the position of the slag-blocking plug 4. The operator then pushes the telescopic rod 7, causing it to slide along the inner wall of the rotating rod 6. When the baffle 8 is in place... After the 8 is pulled to the position where it abuts against the slag-blocking plug 4, the operator can no longer pull the telescopic rod 7. At this time, the operator can manually rotate the rotating rod 17, which will drive the threaded rod 14 and the mounting ring 13 to engage in threaded engagement. The abutment plate 15 connected to the side of the threaded rod 14 abuts against the outer wall of the telescopic rod 7 to achieve the limiting operation of the telescopic rod 7. Then, during the process of rotating the converter body 1 to pour steel, the baffle plate 8 can block the slag-blocking plug 4, which can effectively prevent the slag-blocking plug 4 from floating, thus effectively ensuring the slag-blocking effect of the slag-blocking plug 4. The above is the complete working principle of this utility model.
