[0022] Embodiment:

[0023] As Figures 1 to 4 shown, the present utility model provides a sliding nozzle for a ladle that is convenient to replace, including a placement box 1. A fixed seat 18 is provided below the placement box 1. An installation groove 5 is opened at the bottom of the placement box 1. The fixed seat 18 is clamped in the installation groove 5. A plurality of first knobs 7 are provided at the bottom of the fixed seat 18. The plurality of first knobs 7 all pass through the fixed seat 18 and are clamped in the placement box 1. When the user needs to maintain or replace the internal components of the sliding nozzle, the first knobs 7 can be rotated to release the fixed state between the fixed seat 18 and the placement box 1, and the fixed seat 18 can be removed from the installation groove 5. Through this structure, the user can quickly and conveniently repair or replace the internal components, which effectively reduces the downtime and improves the production efficiency.

[0024] A second adjustment block 10 is provided between the fixed seat 18 and the placement box 1. A plurality of positioning rods 14 are provided at the top of the second adjustment block 10. A plurality of second knobs 15 are provided at the top of the placement box 1. One ends of the plurality of positioning rods 14 all pass through the placement box 1 and are respectively connected to the plurality of second knobs 15. Through the plurality of positioning rods 14, the user can accurately position the position of the second adjustment block 10, ensuring the accuracy and stability during the installation process.

[0025] And through the plurality of second knobs 15, the second adjustment block 10 can be firmly fixed. In this way, it can effectively avoid the influence on the opening accuracy due to the offset of the second adjustment block 10 during the operation of the sliding nozzle, which effectively improves the reliability of the sliding nozzle. And the user only needs to rotate the second knob 15 to remove the second adjustment block 10 from the placement box 1. Through this fixed structure, the safety of the user during disassembly and installation is effectively ensured, and the risk of accidental injury is effectively reduced.

[0026] As Figures 2 to 4As shown in the figure, there is a mounting base 12 below the second adjusting block 10. A fixing groove 11 is formed at the bottom of the second adjusting block 10. The mounting base 12 is clamped in the fixing groove 11, and the mounting base 12 and the fixing groove 11 are connected by threads. A cutting edge 13 is provided on the mounting base 12. When the sliding nozzle stops running, the first adjusting block 6 will reset. During its reset process, the molten steel dripping on the top of the first adjusting block 6 will be scraped off by the cutting edge 13 on the mounting base 12. This can not only reduce the manual intervention, but also avoid the molten steel remaining on the top of the first adjusting block 6 from affecting the internal structure of the sliding nozzle. And after long-term use, the user can rotate the mounting base 12 to remove it from the fixing groove 11 for replacement.

[0027] A first adjusting block 6 is provided between the second adjusting block 10 and the fixing base 18. A slider 9 is provided at the bottom of the first adjusting block 6. Sliding grooves 8 are formed at one ends of both the fixing base 18 and the placing box 1. The slider 9 is clamped in the sliding groove 8 on the fixing base 18. Through the sliding groove 8 and the slider 9, it can not only limit the position of the first adjusting block 6, but also connect the first adjusting block 6 and the fixing base 18 together. This ensures that the first adjusting block 6 can operate within its set range during operation, and also ensures the stability and accuracy during its operation process.

[0028] End caps 2 are clamped at both ends of the placing box 1. A motor 3 is clamped on one side of one group of end caps 2. A screw rod 4 is passed through the first adjusting block 6. One end of the screw rod 4 passes through one group of end caps 2 and is connected to the motor 3, and the other end is clamped in the other group of end caps 2. The user can drive the screw rod 4 through the motor 3 according to the production requirements to control the position of the first adjusting block 6, so as to accurately adjust its opening. Through this structure, the operation error is effectively reduced, and the flow rate adjustment in most different production processes can be satisfied, which effectively improves the production efficiency and safety.

[0029] A connecting pipe 16 is provided on the top of the placing box 1. A swivel joint 17 is clamped on the top of the connecting pipe 16. Through the swivel joint 17, the sliding nozzle can be installed on most different types of equipment for use. This versatility can reduce the dependence on specific equipment and increase the flexibility and application range of the sliding nozzle.

[0030] The specific usage mode and function of this embodiment:

[0031] When using this sliding nozzle, the user can replace the matching adapter 17 according to the equipment model, so as to connect the adapter 17 with the equipment. The adapter 17 effectively increases the applicable range of this sliding nozzle. After installing this sliding nozzle, the user can drive the screw 4 to rotate through its motor 3 according to the production requirements, so as to control the operation of its first adjusting block 6 and adjust its opening to meet the production requirements. This structure effectively reduces manual intervention, which effectively reduces its operation error and improves production efficiency and safety. After using this sliding nozzle for a long time, the user can remove the fixing seat 18 by rotating the first knob 7 to repair or replace the internal components, which effectively improves the efficiency of the maintenance work and reduces the impact on its production efficiency.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
