Description

Technical Field

[0001] This utility model relates to the technical field of converter production equipment, and in particular to a converter molten steel sampler sample block extraction and waste collection system. Background Technology

[0002] In traditional steelmaking, converter steelmaking involves pouring molten iron into a converter, inserting an oxygen lance through the furnace opening, and blowing oxygen into the converter to induce an oxidation-reduction reaction in the molten iron. After smelting for a period of time, the oxygen lance is lifted, and the converter is rotated 90°. Temperature is measured manually, and samples are taken for analysis to determine the composition of the molten steel. The oxygen lance is then inserted again to blow oxygen, and various alloys and other steelmaking raw materials are added simultaneously to adjust the steel composition. This process is repeated until the steel composition meets the required standards.

[0003] The new process allows for automatic temperature measurement and sampling of the auxiliary lance without tilting the furnace (the auxiliary lance is inserted into the furnace through the furnace opening, just like the oxygen lance). After sampling by the auxiliary lance, the sample is manually removed from the sampler and then analyzed. This process achieves automatic temperature measurement and sampling without tilting the furnace, saving production time.

[0004] In the converter's auxiliary lance automatic temperature measurement and sampling system, after the sampler has taken a sample of the molten steel, it automatically detaches from the auxiliary lance, and a new sampler is automatically inserted into the auxiliary lance, moving it to the preparatory position for the next sampling operation. At this point, the sampler needs to be manually removed from the sampler. Because the sampler is inserted into the molten steel of the converter, some steel slag adheres to the sampler body, and because it is inserted into molten steel at over 1000 degrees Celsius, the sampler body temperature is also very high. In the traditional process, after the sampler has taken a sample, it slides through a pipe to the floor where the workers are located. Then, the workers manually open the pipe door, take out the sampler by hand, and then use hammers, shovels, or other tools to break the sampler open, take out the sample, and conduct tests. Finally, the used sampler is thrown into the slag bin. This process is entirely manual, so the manual labor intensity is very high, and there are also certain safety risks. Utility Model Content

[0018] Appendix Figure 1 The image shows the current processing technology after the sampler has taken the sample.

[0019] See Figure 2This invention relates to a system for extracting sample blocks and collecting waste from a converter steel sampler. It includes a pipe chute 8 located on the working floor, which receives the sampler 2. A first cylinder 15 is located on the outer side of the pipe chute near the bottom outlet. The first cylinder is horizontally arranged, and its output end is connected to a tray 17. Driven by the first cylinder, the tray passes horizontally through one side wall of the pipe chute and enters its interior. Furthermore, an infrared limit sensor 16 is installed on the side wall of the pipe chute above the tray. This infrared limit sensor detects whether waste from the sampler remains in the pipe chute. Above the first cylinder, a second cylinder 14 and a third cylinder 10 are arranged horizontally. The piston ends of the second and third cylinders pass through… The sidewall of the pipe chute enters the interior of the pipe chute. The piston ends of the second and third cylinders are equipped with grippers 9. A fourth cylinder 13 is arranged laterally between the second and third cylinders. The piston rod of the fourth cylinder passes through the sidewall of the pipe chute and enters the interior of the pipe chute. A sampling shovel 12 is also provided at the front end of the piston rod of the fourth cylinder. The sampling shovel is inserted into or withdrawn from the pipe chute by the fourth cylinder. Furthermore, the sampling shovel in this invention has a flat plate in the middle and a wedge-shaped tip at its front end. A slag bucket 18 is also provided at the lower end of the pipe chute, which is used to receive waste from the sampler. Furthermore, one sidewall of the slag bucket in this invention is an inclined surface, which is located directly below the lower end of the pipe chute. Furthermore, the gripper in this invention adopts a semi-circular arc structure. The piston end of the corresponding second or third cylinder is connected to the middle position of the outer arc of the semi-circular arc structure, and the inner arc surface of the semi-circular arc structure clamps the sampler by pressing against the outer wall. Furthermore, the cylinder bodies of the first, second, third, and fourth cylinders in this invention are all arranged horizontally and parallel to each other.

[0020] The overall working principle of this utility model is as follows:

[0021] After the sampler completes its sampling, it slides down the pipe chute to the working floor, landing on a tray near the bottom of the chute. At this point, the operator simply presses the start button. The second and third cylinders activate first, clamping the sampler with the front grippers. After a 5-second delay, the fourth cylinder activates. The head of the fourth cylinder is connected to a sampling shovel, which uses the force applied by the cylinder to break open the sampler, pulling out the sample block 11. The operator can then take the sample block for testing. After clicking the standby position, the first, second, third, and fourth cylinders retract, and the used sampler 19 falls into the slag bin below. Once the infrared limit sensor on the upper part of the first cylinder detects that there is nothing in the pipe chute, the first cylinder closes (controlled by a button) and opens (ensuring the pipe chute is closed). The action of the first cylinder here is controlled by the infrared limit sensor's associated signal. The first cylinder automatically opens, sealing the bottom of the pipe and preparing for the next sampler reception.

[0022] In this embodiment, the height of the sampling shovel is set in advance based on the height of the sampler and the fixed height of the sampling block each time. This ensures that the sampling shovel accurately pierces the sampler wall and removes the sampling block each time.

[0023] This utility model system realizes the automatic extraction of sample blocks and collection of waste samplers, which greatly improves production efficiency, reduces the labor intensity of manual sampling, and the entire sample extraction process is carried out in a closed space, which can effectively avoid the occurrence of problems such as burns to staff, and the safety is also effectively guaranteed.
