[0002] In the steel smelting industry, slag balls are a key auxiliary tool widely used in the converter tapping process. Their main function is to block the tapping port when tapping is about to end, effectively blocking the slag from flowing into the ladle, thereby improving the purity and quality of the steel.

[0003] At present, the traditional slag stopper has various designs. Among them, the patent document with the authorized patent number CN205347487U discloses a slag stopper with a truncated cone structure and a delivery handle. This design aims to achieve the effect of rapid immersion in molten steel and efficient slag blocking by setting transverse and longitudinal cross grooves on the side of the truncated cone, while ensuring the delivery accuracy of the slag stopper.

[0023] In a further preferred embodiment of the present invention, the limiting mechanism includes: an assembly frame 9 slidably mounted on the core shell 4, one end of the assembly frame 9 is fixedly connected to the positioning block 8; a spring 10 sleeved on the assembly frame 9; a guide plate 11 sleeved on the assembly frame 9, the top of the guide plate 11 is fixedly connected to the core shell 4; a guide rod 12 fixed on the core shell 4, the guide rod 12 passes through the guide plate 11; and a push plate 13 fixed on the guide rod 12.

[0024] In this embodiment, the assembly frame 9 is slidably mounted on the core shell 4, and one end thereof is fixedly connected to the positioning block 8. When the positioning block 8 needs to be fixed or released, the assembly frame 9 can be operated to drive the movement of the positioning block 8; the spring 10 is sleeved on the assembly frame 9 to provide elastic force for the assembly frame 9 to return to its original position. When an external force acts on the assembly frame 9, the spring 10 will be compressed; when the external force disappears, the spring 10 will push the assembly frame 9 to return to its original position, thereby driving the positioning block 8 to engage or disengage the plug-in block 6; through the elastic force of the spring 10, the automatic engagement and release of the positioning block 8 is achieved, thereby improving the stability and reliability of the internal structure of the slag ball; the guide plate 11 is sleeved on the assembly frame 9, and its top end is fixedly connected to the core shell 4. The guide plate 11 provides a guiding function for the sliding of the assembly frame 9, ensuring that the assembly frame 9 does not deviate from the track during the sliding process; the guide rod 12 is fixed on the core shell 4 and passes through the guide plate 11. The guide rod 12 provides a fixed support point for the push plate 13 and limits the moving direction of the push plate 13; the fixing and supporting function of the guide rod 12 ensures the stability and accuracy of the push plate 13 during the movement; the push plate 13 is fixed on the guide rod 12, and the user can compress or release the spring 10 by operating the push plate 13, thereby driving the movement of the assembly frame 9 and the positioning block 8.

[0025] In a further preferred embodiment of the present invention, a slide rod 15 is slidably mounted on the mounting tube 5 , a conical support block 14 is fixed to the bottom end of the slide rod 15 , and the conical support block 14 contacts one side of the push plate 13 .

[0026] In this embodiment, the slide rod 15 is slidably mounted on the mounting tube 5, and the user can operate the position of the conical support block 14 by sliding the slide rod 15 up and down; the conical support block 14 is fixed to the bottom end of the slide rod 15 and contacts one side of the push plate 13. When the slide rod 15 slides downward, the conical support block 14 pushes the push plate 13, thereby compressing the spring 10 and driving the movement of the assembly frame 9 and the positioning block 8. This design allows the user to indirectly control the state of the positioning block 8 by operating the slide rod 15; the design of the conical support block 14 provides the user with a simple and effective operation method, making the disassembly and installation process of the slag ball more intuitive and easy to understand. At the same time, the conical design of the conical support block 14 helps to provide uniform force when pushing the push plate 13, avoiding structural damage or operational difficulties caused by uneven force.

[0027] In a further preferred embodiment of the present invention, a pressing block 16 is fixed to the top end of the slide rod 15 , and an arc-shaped groove is formed on the pressing block 16 .

[0028] In this embodiment, the push block 16 is fixed at the top of the slide rod 15, providing the user with a point for easy operation and force application. The user can hold the push block 16 with fingers or tools to slide the slide rod 15 up and down, thereby achieving control of the conical support block 14 and the push plate 13.

[0029] In a further preferred embodiment of the present invention, a limiting groove is provided on the plug-in block 6 , and the limiting groove is adapted to the positioning block 8 .

[0030] In this embodiment, a limiting groove is provided on the plug-in block 6, and its shape and size are adapted to the positioning block 8. When the positioning block 8 is inserted into the limiting groove under the action of the spring 10, the connection between the plug-in block 6 and the core shell 4 will be firmly locked; this design ensures the stability and reliability of the slag-blocking ball during use; in use, the positioning block 8 can automatically be inserted into or out of the limiting groove under the action of the assembly frame 9 and the spring 10. When the slag-blocking ball needs to be removed, the user can compress the spring 10 by operating the slide bar 15 and the press block 16 to disengage the positioning block 8 from the limiting groove; when the slag-blocking ball needs to be installed, the user only needs to insert the plug-in block 6 into the core shell 4, and the positioning block 8 will automatically be inserted into the limiting groove under the elastic force of the spring 10.

[0031] In a further preferred embodiment of the present invention, a conical opening is provided on the top of the core shell 4 , and the inner diameter of the conical opening is larger than that of the conical support block 14 .

[0032] In this embodiment, the conical opening is opened at the top of the core shell 4, and its inner diameter is designed to be larger than the maximum diameter of the conical support block 14. This design ensures that the conical support block 14 can smoothly pass through the conical opening when moving upward without being obstructed or stuck; the design of the conical opening provides sufficient space for the up and down movement of the conical support block 14, avoiding operational difficulties or structural damage caused by insufficient space. At the same time, the conical design of the conical opening also helps to guide the smooth movement of the conical support block 14, improving the fluency and accuracy of the operation; when the slide bar 15 slides upward, the conical support block 14 will move upward accordingly. Since the inner diameter of the conical opening is larger than the conical support block 14, the conical support block 14 can easily pass through the conical opening and continue to move upward. This design allows users to experience a smoother and easier operating experience when operating the slide bar 15.

[0033] In a further preferred embodiment of the present invention, the groove block 7 is provided with an inserting hole, and the inserting hole is adapted to the positioning block 8 .

[0034] In this embodiment, the insertion hole is provided on the groove block 7, and its shape and size are adapted to the positioning block 8. When the positioning block 8 is moved to the position of the insertion hole under the action of the spring 10, the positioning block 8 can be smoothly inserted into the insertion hole, thereby achieving a stable connection between the groove block 7 and the core shell 4 or other related components.

[0035] To sum up, the core shell 4 is pluggable and arranged in the truncated cone body 1, which is convenient for disassembly and replacement, and the reuse of the core shell inside the slag stop ball is realized, which effectively reduces the production cost; the design of the mounting tube 5 makes the disassembly and installation process more convenient, and the user can easily complete the disassembly and installation of the slag stop ball by grasping and operating the mounting tube 5; the cooperation between the plug-in block 6 and the groove block 7, as well as the sliding installation and automatic snap-fit ​​design of the positioning block 8, ensure the reliable connection between the core shell inside the slag stop ball and the outer shell, and facilitate disassembly and replacement; the elastic force of the spring 10 realizes the automatic snap-fit ​​and release of the positioning block 8, and improves the stability and reliability of the internal structure of the slag stop ball; the guide plate 11 provides a guiding role for the sliding of the assembly frame 9, ensuring that the assembly frame 9 will not deviate from the track during the sliding process; the guide rod 12 provides a fixed support point for the push plate 13 and limits the moving direction of the push plate 13.
