Description

Technical Field

[0001] This utility model relates to the field of testing technology for steel ladle permeable bricks, specifically a strength testing device for the production of steel ladle permeable bricks. Background Technology

[0002] Porous bricks for steel ladles are an important refractory material component used in the steelmaking process inside the steel ladle (a container for holding steel). They are mainly used to introduce gases (such as argon, nitrogen, etc.) into the molten steel to achieve process purposes such as stirring the molten steel, homogenizing its composition, removing inclusions, or adjusting the temperature of the molten steel.

[0003] The strength testing device for permeable bricks in steel ladles is a device specifically designed to evaluate the structural integrity and load-bearing capacity of permeable bricks under harsh working conditions such as high temperature and high pressure. It uses hydraulic or mechanical loading devices to apply vertical pressure to the permeable bricks, simulating the static pressure of molten steel.

[0004] Existing strength testing devices' clamps can cause localized compression or scratches on the edges or surfaces of permeable bricks during clamping. Localized damage to permeable bricks may affect their actual performance, especially in high-temperature or airflow erosion tests, where the damaged areas may become crack initiation points. Therefore, there is a need to provide a clamp that can conform to the surface of steel ladle permeable bricks to improve the testing quality of steel ladle permeable bricks. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this utility model is a strength testing device for the production of steel ladle permeable bricks, comprising:

[0030] The strength testing device 11 and the steel ladle permeable brick 14 are located inside the strength testing device 11. A pressure block 12 is fixed inside the strength testing device 11, and a display screen 13 is fixed on one side of the strength testing device 11.

[0031] The strength testing device 11 is the outer shell and basic platform of the entire system, used to house the steel ladle permeable brick 14 and conduct strength tests. The pressure block 12 is used to apply vertical pressure to the steel ladle permeable brick 14. The display screen 13 is used to display test data and test results in real time.

[0032] The fixing assembly includes a placement platform 21, a side plate 211, a threaded hole 22, and a threaded rod 23. The placement platform 21 is located inside the strength testing device 11. The steel ladle permeable brick 14 is placed on the upper surface of the placement platform 21. There are two side plates 211, which are fixed on both sides of the placement platform 21 respectively. The threaded hole 22 is opened in the middle of the side plate 211, and the threaded rod 23 rotates through the threaded hole 22.

[0033] The placement platform 21 is the support platform for the steel ladle permeable brick 14. It is located inside the strength testing device 11. There are two side plates 211, which are fixed on both sides of the placement platform 21 respectively. They are used to install threaded holes 22 and support threaded rods 23. The threaded holes 22 are opened in the middle of the side plates 211 and are used in conjunction with the threaded rods 23. The threaded rods 23 pass through the threaded holes 22. One end is connected to the rotating handle 29, and the other end is connected to the connecting shaft 26 through the bearing 24.

[0034] A bearing 24 is rotatably sleeved at the end of the threaded rod 23. A rotating hole 25 is opened on the outer surface of the bearing 24. A connecting shaft 26 passes through the rotating hole 25. A connecting rod 27 is rotatably passed through both sides of the outer surface of the connecting shaft 26. A fixing plate 28 is fixed on one side of the connecting rod 27. One side of the fixing plate 28 is arc-shaped. A rotating handle 29 is fixed at one end of the threaded rod 23.

[0035] The bearing 24 is used to support the connecting shaft 26 and reduce rotational friction. The rotating hole 25 is used to accommodate the connecting shaft 26. The connecting shaft 26 passes through the rotating hole 25. One end is connected to the bearing 24, and the other end is connected to the fixing plate 28 through the connecting rod 27. The two ends of the connecting rod 27 are connected to the connecting shaft 26 and the fixing plate 28 respectively, converting the linear motion of the connecting shaft 26 into the fitting action of the fixing plate 28. One side of the fixing plate 28 is arc-shaped and is used to fit the outer surface of the steel ladle permeable brick 14. By pushing the connecting rod 27, the fixing plate 28 limits the permeable brick on the placement platform 21 to prevent it from shifting or tilting during the test.

[0036] Working principle:

[0037] Place the steel ladle permeable brick 14 on the placement platform 21, then rotate the rotating handle 29. The rotating handle 29 drives the threaded rod 23 to rotate. The threaded rod 23 rotates in the threaded hole 22 and moves horizontally in the side plate 211. Under the connection of the bearing 24, the connecting shaft 26 also moves horizontally. The connecting shaft 26 drives the connecting rod 27 to move and rotates the connecting fixing plate 28 so that the fixing plate 28 fits against the outer surface of the steel ladle permeable brick 14, limiting the steel ladle permeable brick 14 inside the strength testing device 11.

[0038] This step does not require changing the fixture or adjusting the complex structure. Simply rotating the handle 29 can achieve quick adaptation, improving testing efficiency and flexibility. The fixing plate 28 moves smoothly through the connecting rod 27 and the bearing 24, avoiding direct squeezing or scratching of the outer surface of the steel ladle permeable brick 14.

[0039] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The adjustment assembly includes sliders 31, mounting holes 32, and springs 33. There are two sliders 31, which are fixed to the lower surface of the placement platform 21. The mounting holes 32 are opened on both sides of one end of the sliders 31. There are two sets of springs 33, which are fixed to both sides of the two sliders 31 respectively.

[0041] There are two sliders 31, each fixed to the lower surface of the placement platform 21, used to support the placement platform 21 and allow it to slide along the slide rail 35. Mounting holes 32 are formed on both sides of one end of each slider 31 for mounting springs 33 and locking pins 34. There are two springs 33 in a set, fixed to both sides of each of the two sliders 31. They provide elasticity to the locking pins 34, causing them to automatically extend into the locking grooves 36 when no external force is applied, thereby locking the placement platform 21.

[0042] The end of the spring 33 is fixed with a locking post 34, and the upper surface of the platform 21 is fixed with slide rails 35 on both sides. The slide rails 35 slide through the slider 31. The outer surface of the slide rails 35 is provided with a locking groove 36, and the end of the locking post 34 extends into the corresponding locking groove 36.

[0043] The locking pin 34 is fixed to the end of the spring 33, and its end extends into the slot 36 on the outer surface of the slide rail 35. The slide rail 35 is fixed to both sides of the upper surface of the placement platform 21, and slides through the slider 31. The slot 36 is opened on the outer surface of the slide rail 35 to accommodate the locking pin 34. It is the core component of the locking mechanism. By cooperating with the locking pin 34, the movement of the placement platform 21 is restricted.

[0044] Working principle:

[0045] When replacing the test ladle permeable brick 14, press the locking post 34 inward to make the locking post 34 exit from the locking groove 36, compress the spring 33 in the mounting hole 32, then pull the placement platform 21 to move the placement platform 21 to the front end of the slide rail 35, and rotate the threaded rod 23 to easily remove and replace the ladle permeable brick 14.

[0046] This step involves pressing the locking post 34 to unlock the placement platform 21. With the sliding design of the slide rail 35, the placement platform 21 can be quickly pulled out, making it convenient to replace the steel ladle permeable brick 14. This significantly reduces replacement time and improves overall testing efficiency.
