Description

Technical Field

[0001] This utility model relates to the field of steel sampling technology, specifically to a sampling device for detecting molten steel refined outside the ladle. Background Technology

[0002] In the ladle refining process, it is necessary to perform temperature measurement, sampling, and oxygen determination on the molten steel inside the ladle to achieve the required temperature and composition, meet the requirements of constant-speed continuous casting, and ensure product quality. Currently, sampling devices are often used to sample the molten steel inside the ladle. In practice, these devices have advantages such as simple operation, stable structure, and good performance.

[0003] The prior art discloses a molten steel sampler with announcement number CN221426070U. This utility model requires a threaded rod installed inside the outer cup to move the inner cup up and down, thereby pushing out excess molten steel from the outer cup. During this process, the molten steel comes into contact with the threaded rod, and the rotation of the threaded rod requires the application of grease. Contact with the high-temperature molten steel can damage the grease, and failure to apply grease will reduce the service life of the threaded rod, thus reducing the practicality of this utility model. Furthermore, the sampled molten steel needs to be poured into a designated container; without an auxiliary structure, it is impossible to ensure that the poured molten steel is accurately poured into the designated container, thus posing a potential hazard to the accurate pouring of molten steel.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a sampling device for detecting molten steel in ladle refining. It has the advantages of avoiding spillage of molten steel during sampling without the need for a threaded rod structure, and has an auxiliary structure to ensure that the poured molten steel is accurately poured into a designated container, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the advantages of avoiding spillage of molten steel during sampling without the need for a threaded rod structure, and to ensure accurate pouring of molten steel into the designated container using an auxiliary structure, the specific technical solution adopted by this utility model is as follows:

[0009] A sampling device for detecting molten steel refined outside the ladle includes a sampling barrel. An mounting block is fixedly installed on the outer wall of the sampling barrel. Two sets of vertical rods are mounted on the upper part of the mounting block, and handles are mounted on the upper ends of the two sets of vertical rods. Positioning blocks are slidably sleeved on the side walls of the two sets of vertical rods. A barrel cover is installed on one side of the positioning block, and a push plate is slidably installed inside the barrel cover. A liquid outlet is fixedly passed through the outer wall of the barrel cover. A concave frame is installed on the side wall of the handle, and a lead lever is installed inside the concave frame via a bearing. A lead screw sleeve is sleeved on the side wall of the lead lever, and a connecting plate is fixedly sleeved on the side wall of the lead screw sleeve. A connecting rod is installed between the positioning block and the connecting plate. An annular groove is provided on the outer wall of the open end of the sampling barrel, and an insertion tube is installed at the lower end of the barrel cover.

[0010] Furthermore, a handwheel is installed at one end of the lever.

[0011] Furthermore, the lead lever and the lead screw thread are mutually engaged.

[0012] Furthermore, a guide rod slides through the upper part of the socket plate, and the two ends of the guide rod are fixedly connected to the inner top and bottom surfaces of the concave frame, respectively.

[0013] Furthermore, a limiting plate is installed on the side wall of the grip, and a sliding rod slides through the upper part of the limiting plate. One end of the sliding rod slides through the upper part of the barrel cover. One end of the sliding rod is fixedly connected to the upper part of the push plate.

[0014] Furthermore, the inner top surface of the barrel cover is perforated with a breathable mesh.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a sampling device for detecting molten steel in ladle refining, which has the following beneficial effects:

[0017] (1) This utility model adopts a barrel cover. When actually using the sampling device for testing molten steel outside the furnace, the operator can hold the handle with one hand and rotate the handwheel with the other hand. The handwheel can drive the lead screw to rotate. Since the lead lever and the lead screw sleeve are mutually engaged, the rotating lead lever can push the lead screw sleeve to move upward. The upward-moving lead screw sleeve can move the positioning block upward through the sleeve plate and the connecting rod. The upward-moving positioning block can drive the barrel cover to move upward. When there is a gap between the barrel cover and the sampling barrel, the sampling barrel can be placed into the ladle. Molten steel can pass through the gap between the sampling barrel and the barrel cover. Finally, the molten steel can be collected in the sampling barrel. Inside the sample tank, the operator then manually rotates the handwheel in the opposite direction. The handwheel drives the lead lever to rotate in the opposite direction, which in turn causes the lead screw sleeve to move downwards. The downward-moving lead screw sleeve, through the connecting plate and connecting rod, causes the positioning block to move downwards. The downward-moving positioning block causes the tank cover to move towards the sampling tank. When the insertion tube moves into the interior of the annular groove, the sampling tank and the tank cover are connected. At this point, the molten steel inside the sampling tank cannot be discharged. With the tank cover in place, the spillage of the sampled molten steel can be avoided without the need for a threaded rod structure, thus improving the practicality of the sampling device for testing molten steel in ladle refining.

[0018] (2) This utility model adopts a push plate and a liquid outlet. According to the above operation, after the molten steel is sampled, the sampling bucket is moved to a suitable position by using the handle. At this time, the sampling bucket is tilted. When the liquid outlet is moved above the designated container, the operator pulls the handle by hand. The handle can move the push plate and the fixed hole plate through the sliding rod. The fixed hole plate and the limiting plate will squeeze the telescopic spring. When the push plate is moved above the liquid outlet, the sampling bucket is tilted. The molten steel inside can be moved out through the liquid outlet and finally fall into the designated container. When the use is finished, the operator releases the handle. The telescopic spring can push the fixed hole plate by its own elastic force, so that the fixed hole plate drives the sliding rod to reset. The sliding rod can drive the push plate to reset, waiting for the next use. The push plate and liquid outlet have an auxiliary structure, which can ensure that the poured molten steel is accurately poured into the designated container, thus ensuring the accurate pouring of the sampling device for testing molten steel outside the furnace.

An annular groove 13 is provided on the outer wall of the opening end of the sampling barrel 1. An insertion tube 14 is installed at the lower end of the barrel cover 2. With the barrel cover 2, the spillage of the sampled molten steel can be avoided without the need for a threaded rod structure, thus improving the practicality of the sampling device for testing molten steel in ladle refining.

[0030] In one embodiment, a handwheel 23 is installed at one end of the wire lever 8, which facilitates the rotation of the wire lever 8.

[0031] In one embodiment, the lead lever 8 and the lead screw sleeve 9 are threaded together to facilitate adjustment of the working position of the lead screw sleeve 9.

[0032] In one embodiment, a guide rod 11 is slidably passed through the upper part of the socket plate 10, and the two ends of the guide rod 11 are fixedly connected to the inner top surface and bottom surface of the concave frame 7, respectively.

[0033] In one embodiment, a limiting plate 17 is installed on the side wall of the handle 5, and a sliding rod 16 slides through the upper part of the limiting plate 17. One end of the sliding rod 16 slides through the upper part of the barrel cover 2. One end of the sliding rod 16 is fixedly connected to the upper part of the push plate 15. A handle 18 is installed on the other end of the sliding rod 16. A fixing hole plate 19 is fixedly sleeved on the side wall of the sliding rod 16.

[0034] In one embodiment, a breathable mesh 22 runs through the inner top surface of the barrel cover 2, which provides protection for the movement and use of the push plate 15.

[0035] Working principle:

[0036] In actual use of the sampling device for testing molten steel in ladle refining, the operator can hold handle 5 with one hand and rotate handwheel 23 with the other. Handwheel 23 drives the lead screw to rotate. Since the lead lever 8 and lead screw sleeve 9 are threadedly engaged, the rotating lead lever 8 can push the lead screw sleeve 9 upward. The upward-moving lead screw sleeve 9 can move the positioning block 6 upward through the sleeve plate 10 and connecting rod 12. The upward-moving positioning block 6 can drive the barrel cover 2 upward. When there is a gap between the barrel cover 2 and the sampling barrel 1, the sampling barrel 1 can be placed into the ladle. Molten steel can pass through the gap between the sampling barrel 1 and the barrel cover 2. Finally, the molten steel can accumulate inside the sampling barrel 1. Then, the operator manually rotates the handwheel 23 in the opposite direction. The handwheel 23 drives the lead lever 8 to rotate in the opposite direction. The reverse rotation of the lead lever 8 causes the lead screw sleeve 9 to move down. The moving lead screw sleeve 9, through the sleeve plate 10 and the connecting rod 12, causes the positioning block 6 to move down. The moving positioning block 6 causes the barrel cover 2 to move towards the sampling barrel 1. When the insertion tube 14 moves into the annular groove 13, the sampling barrel 1 and the barrel cover 2 are connected. At this time, the molten steel inside the sampling barrel 1 cannot be discharged. Through the barrel cover 2, it is not necessary to use any other means. The threaded rod structure prevents molten steel from spilling during sampling, improving the practicality of the sampling device for testing molten steel in ladle refining. Furthermore, according to the above operation, after molten steel sampling is completed, the sampling bucket 1 is moved to a suitable position using the handle 5. The sampling bucket 1 is then tilted. When the outlet nozzle 21 is above the designated container, the operator manually pulls the handle 18. The handle 18, through the slide rod 16, moves the push plate 15 and the fixing plate 19. The fixing plate 19 and the limiting plate 17 compress the telescopic spring 20. When the push plate 15 moves above the outlet nozzle 21... After tilting the sampling bucket 1, the molten steel inside can be removed through the outlet nozzle 21 and finally fall into the designated container. When the sampling bucket is finished, the operator releases the handle 18. The telescopic spring 20, under its own elastic force, can push the fixed orifice plate 19, so that the fixed orifice plate 19 drives the slide rod 16 to reset. The slide rod 16 can drive the push plate 15 to reset, ready for the next use. The push plate 15 and the outlet nozzle 21 have an auxiliary structure that can ensure that the poured molten steel is accurately poured into the designated container, thus ensuring the accurate pouring of the sampling device for testing molten steel in ladle refining.
