[0002] Slide block is a key refractory material used in continuous casting steelmaking to control the flow of molten steel at the bottom of the ladle. It is typically made of high-alumina, zirconium, or magnesia-carbon materials. Its core function is to regulate the flow rate of molten steel from the ladle to the tundish through the precise opening and closing of the sliding mechanism, ensuring the stability and safety of the continuous casting process. Slide blocks must withstand the scouring of molten steel at temperatures exceeding 1600℃, chemical corrosion, and mechanical wear; therefore, they possess high strength, thermal shock resistance, and corrosion resistance. During production, slide blocks require shaping using a sizing device.

[0003] For example, authorization announcement number CN210820152U discloses a shaping device for baffle brick production, including a horizontal plate, a bottom plate at the bottom of the horizontal plate, and first hydraulic telescopic rods fixedly connected to both sides of the top of the horizontal plate. A connecting plate is fixedly connected to the output end of the first hydraulic telescopic rod, a housing is fixedly connected to the surface of the connecting plate, and a second hydraulic telescopic rod is fixedly connected to the top of the connecting plate.

[0004] However, the shaping device in the above technology can only shape bricks one by one, and cannot simultaneously shape a large number of bricks, resulting in low production efficiency; therefore, the market urgently needs to develop a shaping structure for the preparation of magnesium-calcium-carbon steel ladle sliding bricks to help people solve the existing problems. Utility Model Content

[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] Please see Figure 1-4 An embodiment of this utility model provides a shaping structure for preparing magnesium-calcium-carbon steel ladle sliding bricks, including a shaping platform 1. A horizontal rectangular slot 101 is provided in the middle of the upper end surface of the shaping platform 1. Guide rails 102 are fixedly connected to both the front and rear ends of the rectangular slot 101. A receiving plate 2 is provided on the upper end surface of the shaping platform 1. The front and rear ends of the lower end of the receiving plate 2 are slidably connected to the two guide rails 102 respectively through sliders 201. The two guide rails 102 extend out from both sides of the shaping platform 1. The receiving plate 2 slides into the middle of the upper end of the shaping platform 1 on the two guide rails 102.

[0024] Please see Figure 2 and Figure 3 Support columns 3 are fixedly connected to both ends of the upper surface of the shaping table 1. A top plate 301 is fixedly connected to the upper ends of the four support columns 3. Guide rods 304 are fixedly connected to the lower surface of the top plate 301 between the two ends of the middle of the upper surface of the shaping table 1 and the lower surface of the top plate 301. A shaping box 4 is connected to the middle of the four guide rods 304. A rectangular slot 401 is provided on the upper surface of the shaping box 4. Multiple shaping through slots 402 are arranged in an array between the lower end of the rectangular slot 401 and the lower surface of the shaping box 4. A lifting plate 5 is connected to the upper end of the middle of the four guide rods 304. A lifting plate 5 is arranged in an array on the lower surface of the lifting plate 5. Multiple clamping columns 501 are fixedly connected, and the arrayed clamping columns 501 are vertically aligned with the arrayed shaping through slots 402. Linkage blocks 403 are fixedly connected to the upper middle of the end faces on both sides of the shaping box 4. Electrically controlled telescopic rods 303 are fixedly connected to the middle of both sides of the lower end face of the top plate 301. The lower ends of the telescopic ends of the two electrically controlled telescopic rods 303 are fixedly connected to the upper end faces of the two linkage blocks 403 respectively. A hydraulic rod 304 is fixedly connected to the middle of the upper end face of the top plate 301. The lower end of the telescopic end of the hydraulic rod 304 passes through the top plate 301 and is fixedly connected to the middle of the upper end face of the lifting plate 5. When the receiving plate 2 moves to the shaping position... After the upper middle of platform 1 is reached, two electrically controlled telescopic rods 303 synchronously drive the shaping box 4 to descend, causing the lower end face of the shaping box 4 to press down on the receiving plate 2. This allows the receiving plate 2 to support the bottom of multiple shaping channels 402. By pouring the steel ladle sliding brick material into the rectangular slot 401 and gradually filling the multiple shaping channels 402, the hydraulic rod 304 drives the lifting plate 5 to descend, causing multiple clamping columns 501 to pass through the rectangular slot 401 and insert into the multiple shaping channels 402 respectively. This compacts and shapes the material inside the shaping channels 402. After compaction, the shaping box 4 and the lifting plate 5 rise synchronously (i.e., the clamping columns...). 501 does not detach from the shaping channel 402, effectively preventing residual material inside the rectangular slot 401 from flowing into the shaping channel 402 and contaminating the shaped brick. After shaping, the brick detaches from the shaping channel 402 under gravity and is neatly arranged on the receiving plate 2. The receiving plate 2 can then be moved out of the upper end of the shaping table 1 via the guide rail 102. When the next receiving plate 2 moves to the shaping position, it descends synchronously via the shaping box 4 and the lifting plate 5. When the lower end of the shaping box 4 is in contact with the upper end of the receiving plate 2, the lifting plate 5 rises, causing the pressing column 501 to detach from the shaping channel 402, and the loading operation can be carried out again.

[0025] Please see Figure 3 and Figure 4The upper ends of both sides of the front and rear end faces of the shaping box 4 are fixedly connected to the first guide member 404. The middle parts of the four guide rods 304 pass through the interior of the four first guide members 404 respectively. The upper ends of both sides of the front and rear end faces of the lifting plate 5 are fixedly connected to the second guide member 502. The upper ends of the middle parts of the four guide rods 304 pass through the interior of the four second guide members 502 respectively. The lifting and lowering of the shaping box 4 and the lifting plate 5 are guided by the four guide rods 304.

[0026] Working Principle: In use, the receiving plate 2 is first pushed along the guide rail 102 into the upper center of the shaping table 1 for positioning. The shaping box 4 is then driven downwards along the guide rod 304 by the electrically controlled telescopic rod 303, causing the lower end face of the shaping box 4 to press firmly against the receiving plate 2, forming a seal. The operator pours the magnesium-calcium carbonaceous raw material into the rectangular slot 401 of the shaping box 4. Under gravity, the raw material automatically fills into each shaping channel 402. Subsequently, the hydraulic rod 302 drives the lifting plate 5 downwards, causing the arrayed pressing columns 501 to simultaneously insert into the corresponding shaping channels 402, uniformly compacting the raw material. After pressing is complete, the electrically controlled telescopic rod 303 and the hydraulic rod 302 are simultaneously lifted, keeping the shaping box 4 and the pressing columns 501 relatively stationary during the upward movement. This ensures that the pressing columns 501 do not detach from the shaping channels 402, effectively preventing residual raw material from contaminating the formed brick. After the bricks are shaped, they fall off due to their own weight and are neatly arranged on the receiving plate 2. Finally, the receiving plate 2 is pulled out along the guide rail 102 to complete the batch removal of parts.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
