Description

Technical Field

[0001] This utility model relates to the technical field of converter slag-blocking rods, specifically a snap-lock type slag-blocking rod. Background Technology

[0002] Slag-blocking rods are a common tool in the metallurgical industry, especially in the steelmaking process. During the tapping process, slag-blocking rods can effectively prevent molten slag in the converter or electric furnace from flowing into the ladle with the molten steel. This is because molten slag contains a large number of impurities, oxides, etc. If it enters the ladle, it will affect the quality of the molten steel, leading to an increase in inclusions in the steel, reducing the purity of the steel, and thus affecting the performance of the steel.

[0003] A converter tapping slag-blocking rod with authorization announcement number CN211814549U is described. The slag-blocking rod is funnel-shaped, and its outer edge wall is curved. A steel-filtering water trough is provided on the outer edge wall of the slag-blocking rod, extending axially from top to bottom along the slag-blocking rod. The top end of the steel-filtering water trough and the top surface of the slag-blocking rod are closed, and the bottom end of the steel-filtering water trough and the bottom end of the slag-blocking rod are also closed. The top surface of this converter tapping slag-blocking rod is relatively smooth, and the welding fixing method makes it difficult to remove the slag-filtering rod after slag is filtered. At the same time, this slag-blocking rod will concentrate molten slag in the tapping hole, making it impossible to clean the tapping hole.

[0004] To address the aforementioned issues, a snap-lock connection type slag-blocking rod is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a snap-lock slag-blocking rod, which solves the problem that the top surface of the existing converter tapping slag-blocking rod in the background technology is relatively smooth, and the welding fixing method makes it difficult to remove the slag-blocking rod after slag filtering. At the same time, this slag-blocking rod will concentrate molten slag in the tapping hole, making it impossible to complete the tapping hole cleaning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a snap-fit ​​slag-blocking rod, comprising a converter outlet pipe, wherein a slag-blocking rod snap-fitting mechanism is slidably disposed inside the converter outlet pipe, and a slag-blocking filter mechanism is rotatably connected to one side of the slag-blocking rod snap-fitting mechanism; the converter outlet pipe includes an outlet pipe, wherein two sets of baffles are fixedly disposed inside the outlet pipe, the two sets of baffles being symmetrically arranged about the center of the outlet pipe; the slag-blocking rod snap-fitting mechanism includes a cleaning block disposed through the outlet pipe, a connecting rod fixedly disposed on one side of the cleaning block, and a snap-fitting component for inserting the baffles fixedly disposed on the connecting rod; the slag-blocking filter mechanism includes a hemispherical block rotatably connected to the connecting rod.

[0007] Preferably, the stop block has a centrally located insertion port.

[0008] Preferably, the cleaning block has spiral openings on both sides.

[0009] Preferably, the connecting rod is fixedly provided with a threaded opening on one side corresponding to the fastening assembly.

[0010] Preferably, the fastening assembly includes a limiting block fixedly mounted on the connecting rod, and insert blocks are fixedly mounted on both sides of the limiting block.

[0011] Preferably, the slag-blocking and filtering mechanism further includes a hexagonal nut that is sleeved with the connecting rod, and a collar is fixedly provided on one side of the hexagonal nut. The hexagonal nut, the collar, and the hemispherical block are fixed to each other.

[0012] Preferably, the center of the hemispherical block has an internal thread that rotatably connects with the threaded opening.

[0013] Preferably, the outer wall of the hemisphere has an arc-shaped groove, and the interior of the hemisphere has a straight groove. The arc-shaped groove and the straight groove are arranged in a circular array of six groups about the center of the hemisphere.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The present invention provides a snap-fit ​​slag-blocking rod, which, through the combination of converter outlet pipe and cleaning block, fixes the outlet pipe and the block to each other. The symmetrical arrangement of the block at the center facilitates the insertion and removal of the cleaning block and the snap-fit ​​assembly. When the cleaning block moves, it can rotate along the block to achieve internal cleaning of the outlet pipe. This solves the problem that the existing converter tapping slag-blocking rods concentrate molten slag in the tapping opening and cannot complete the tapping opening cleaning.

[0016] 2. This utility model provides a snap-fit ​​slag-blocking rod. Through the setting of the slag-blocking rod snap-fitting mechanism and the slag-blocking and filtering mechanism, the snap-fitting and fixing steps of the slag-blocking rod are as follows: push the snap-fitting component forward to the front end of the block, rotate it 90 degrees until the snap-fitting component can be aligned with the block and inserted, and after insertion, rotate the hemispherical block until the front end of the hemispherical block and the snap-fitting component are in contact with each other to achieve snap-fitting. The contact setting between the hemispherical block and the snap-fitting component can also prevent molten steel from entering the joint gap between the hemispherical block and the connecting rod, thus achieving protection. This solves the problem that the top surface of the existing converter tapping slag-blocking rod is relatively smooth, and the welding fixing method makes it difficult to remove the slag-blocking rod after slag filtering.

[0025] Combination Figure 1 This utility model discloses a snap-fit ​​type slag-blocking rod, including a converter outlet pipe 1. A slag-blocking rod snap-fitting mechanism 2 is slidably arranged inside the converter outlet pipe 1. A slag-blocking filter mechanism 3 is rotatably connected to one side of the slag-blocking rod snap-fitting mechanism 2. The converter outlet pipe 1 includes an outlet pipe 11. Two sets of baffles 12 are fixedly arranged inside the outlet pipe 11. The two sets of baffles 12 are symmetrically arranged about the center of the outlet pipe 11. The slag-blocking rod snap-fitting mechanism 2 includes a cleaning block 21 that penetrates through the outlet pipe 11. A connecting rod 22 is fixedly arranged on one side of the cleaning block 21. A snap-fitting component 23 for inserting the baffle 12 is fixedly arranged on the connecting rod 22. The slag-blocking filter mechanism 3 includes a hemispherical block 33 that is rotatably connected to the connecting rod 22.

[0026] Specifically, the outlet pipe 11 and the stop block 12 are fixed to each other. The symmetrical arrangement of the stop block 12 facilitates the insertion and removal of the cleaning block 21 and the fastening component 23. When the cleaning block 21 moves, it can rotate along the stop block 12 to achieve internal cleaning of the outlet pipe 11. The fastening and fixing steps of the slag-blocking rod are as follows: push the fastening component 23 forward to the front end of the stop block 12, rotate it ninety degrees until the fastening component 23 can be aligned with the stop block 12 and inserted, and after insertion, rotate the hemispherical block 33 until the front end of the hemispherical block 33 is in contact with the fastening component 23 to achieve fastening. The contact setting of the hemispherical block 33 and the fastening component 23 can also prevent molten steel from entering the sleeve gap between the hemispherical block 33 and the connecting rod 22, thus achieving protection.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1:

[0029] Combination Figures 2-5 The block 12 has a centrally located insertion port 121 for inserting the slag-blocking rod fastening mechanism 2 to fix the slag-blocking rod.

[0030] The cleaning block 21 has spiral openings 211 on both sides. The opening of the spiral openings 211 allows the slag-blocking rod fastening mechanism 2 to rotate synchronously when it moves horizontally, so as to scrape and clean the inside of the outlet pipe 11.

[0031] The connecting rod 22 is fixedly provided with a threaded opening 221 on one side corresponding to the fastening assembly 23. The threaded opening 221 is used to rotatably connect the slag-blocking filter mechanism 3. The slag-blocking filter mechanism 3 can be adjusted by rotating along the threaded opening 221 to adjust the fixed position between the slag-blocking rod fastening mechanism 2 and the slag-blocking filter mechanism 3.

[0032] The fastening assembly 23 includes a limiting block 231 fixedly mounted on the connecting rod 22. Insert blocks 232 are fixedly mounted on both sides of the limiting block 231. The limiting block 231 limits the rotation of the hemispherical block 33 to prevent the insert post 233 from interfering with the hemispherical block 33. When the insert post 233 is inserted into the socket 121, the insert block 232 and the stop block 12 fit together.

[0033] Example 2:

[0034] Combination Figure 4 and Figure 5 The slag-blocking and filtering mechanism 3 also includes a hexagonal nut 31 that is sleeved with the connecting rod 22. A collar 32 is fixedly provided on one side of the hexagonal nut 31. The hexagonal nut 31, the collar 32 and the hemispherical block 33 are fixed to each other. The hexagonal nut 31 is an auxiliary setting to facilitate the control of the rotation of the hemispherical block 33. The collar 32 is hollow inside to facilitate the rotation and forward movement of the hemispherical block 33.

[0035] The center of the hemispherical block 33 has an internal thread 331 that is rotatably connected to the threaded opening 221. The internal thread 331 and the threaded opening 221 are matched to complete the connection.

[0036] The outer wall of the hemispherical block 33 is provided with an arc-shaped groove 332, and the inside of the hemispherical block 33 is provided with a straight groove 333. The arc-shaped groove 332 and the straight groove 333 are distributed in a circular array about the center of the hemispherical block 33 in six groups. The arc-shaped groove 332 realizes the filtration and diversion of steel slag, and the straight groove 333 realizes the filtration of steel slag. The arc-shaped groove 332 and the straight groove 333 are interconnected to reduce the blind area of ​​the gap.
