Description

Technical Field

[0001] This utility model relates to the field of steel measurement technology, and specifically discloses an automatic lifting temperature and oxygen determination device for a furnace post-blowing argon station. Background Technology

[0002] The argon blowing station after the furnace in Jinsteel's No. 2 steelmaking plant plays a crucial role in steel production. It homogenizes the composition and temperature of molten steel, removes gases and inclusions, promotes slag reaction, and optimizes steel fluidity, creating favorable conditions for subsequent refining processes. This reduces refining time and the amount of refining agents used, improves refining efficiency, and lowers production costs. During steel smelting, temperature and oxygen levels in the molten steel must be measured using temperature and oxygen lances.

[0003] Currently, the measurement of molten steel is mostly done manually using handheld temperature guns and oxygen lances. During the measurement process, molten steel splashes can easily cause injuries to personnel, posing a safety hazard. At the same time, manual measurement can easily damage the temperature guns and oxygen lances due to human error, leading to increased maintenance costs. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-3 An automatic lifting temperature measuring and oxygen determination device for a furnace post-arc blowing station includes two horizontal bars 1 distributed front to back, and two mounting rods 2 distributed left to right are fixedly connected between the two horizontal bars 1. The outer walls of the two mounting rods 2 are rotatably connected to two guide wheels 3 distributed front to back. The multiple guide wheels 3 are grouped in pairs, and a first steel wire rope 4 and a second steel wire rope 5 are respectively arranged between each group of guide wheels 3. The first steel wire rope 4 and the second steel wire rope 5 pass around the two groups of guide wheels 3 respectively. The right end of the first steel wire rope 4 and the second steel wire rope 5 is provided with a placement box 6 with an open structure on the right end. The left end of the first steel wire rope 4 and the second steel wire rope 5 is respectively provided with a temperature measuring gun 7 and an oxygen determining gun 8.

[0022] The first wire rope 4 and the second wire rope 5 are both provided with fixing mechanisms between them and the two placement boxes 6, the temperature measuring gun 7 and the oxygen-fixing gun 8. The outer walls of the first wire rope 4 and the second wire rope 5 are provided with limiting mechanisms located above the two placement boxes 6, the temperature measuring gun 7 and the oxygen-fixing gun 8, respectively.

[0023] In this embodiment: During use, the device is first moved to a suitable position so that the temperature measuring gun 7 and the oxygen-fixing gun 8 are positioned above the molten steel pool. Then, the counterweights 18 are removed from the two placement boxes 6 and placed in the storage box 17, ensuring that the weight of the two placement boxes 6 is less than the weight of the temperature measuring gun 7 and the oxygen-fixing gun 8. The weight of the temperature measuring gun 7 and the oxygen-fixing gun 8 then pulls the first steel wire rope 4 and the second steel wire rope 5 respectively. Simultaneously, two sets of guide wheels 3 guide the first steel wire rope 4 and the second steel wire rope 5, causing the temperature measuring gun 7 and the oxygen-fixing gun 8 to move downwards into the molten steel. The temperature measuring gun 7 and the oxygen-fixing gun 8 then irradiate the molten steel. The temperature and oxygen determination guns can be used to measure temperature and determine oxygen levels, avoiding the safety hazards caused by manual temperature measurement and preventing equipment damage due to human error, thus reducing maintenance costs. After the measurement is completed, the counterweight 18 in the storage box 17 can be placed into the two placement boxes 6 respectively, so that the weight of the two placement boxes 6 is greater than the weight of the temperature measuring gun 7 and the oxygen determining gun 8. Then, the temperature measuring gun 7 and the oxygen determining gun 8 are pulled upward to the reset position by the first steel wire rope 4 and the second steel wire rope 5. During the movement of the temperature measuring gun 7 and the oxygen determining gun 8, the movement distance of the temperature measuring gun 7 and the oxygen determining gun 8 can be limited by the limiting mechanism to prevent the temperature measuring gun 7 and the oxygen determining gun 8 from moving too far.

[0024] When the two placement boxes 6, the temperature measuring gun 7, and the oxygen-fixing gun 8 are damaged and need to be replaced, they can be quickly disassembled through the fixing mechanism, making them convenient to use.

[0025] As a technical optimization of this utility model, the fixing mechanism includes a slot 9 fixedly connected to the end of the wire rope and having an open structure at the lower end. Threaded holes 10 are opened through the left and right side walls of the slot 9. The two threaded holes 10 are connected to a first bolt 11 by a common thread. The upper surfaces of the two placement boxes 6, the temperature measuring gun 7 and the oxygen-fixing gun 8 are fixedly connected to pins 12 that are respectively matched with multiple slots 9. A through hole 13 is opened through the left side wall of the pin 12, and the first bolt 11 passes through the through hole 13.

[0026] In this embodiment: when disassembling the two placement boxes 6, the temperature measuring gun 7 and the oxygen-fixing gun 8, the first bolt 11 is unscrewed from the two threaded holes 10, so that the first bolt 11 releases the limiting and fixing state of the pin 12. Then, the pin 12 is pulled out from the slot 9 through the two placement boxes 6, the temperature measuring gun 7 and the oxygen-fixing gun 8, thereby completing the disassembly of the two placement boxes 6, the temperature measuring gun 7 and the oxygen-fixing gun 8.

[0027] When installing the two placement boxes 6, the temperature measuring gun 7, and the oxygen-fixing gun 8, the pin 12 is inserted into the slot 9 through the two placement boxes 6, the temperature measuring gun 7, and the oxygen-fixing gun 8, and the first bolt 11 is screwed into the two threaded holes 10, thereby installing and fixing the two placement boxes 6, the temperature measuring gun 7, and the oxygen-fixing gun 8. Since the cross-section of the slot 9 and the pin 12 are both rectangular, it is easy to align the through hole 13 with the two threaded holes 10, thereby making it easy for the first bolt 11 to pass through the through hole 13.

[0028] As a technical optimization of this utility model, the limiting mechanism includes a sliding sleeve 14 sleeved on the outer wall of the wire rope, and a second bolt 15 is threadedly connected to the outer wall of the sliding sleeve 14, with one end of the second bolt 15 abutting against the outer wall of the wire rope.

[0029] In this embodiment: the sliding sleeve 14 can limit the movement distance of the temperature measuring gun 7 and the oxygen-fixing gun 8; the second bolt 15 can fix the sliding sleeve 14; and by loosening the second bolt 15, the position of the sliding sleeve 14 can be adjusted, thereby adjusting the movement distance of the temperature measuring gun 7 and the oxygen-fixing gun 8.

[0030] As a technical optimization of this utility model, two left and right distributed support legs 16 are fixedly connected to the lower end face of the two horizontal bars 1, and a storage box 17 is fixedly connected between the two support legs 16 on the right side, and a counterweight block 18 is placed inside the storage box 17.

[0031] In this embodiment, the storage box 17 facilitates the storage of the counterweight 18.

[0032] As a technical optimization of this utility model, the lower ends of the multiple support legs 16 are all equipped with universal wheels 19 with brakes.

[0033] In this embodiment, multiple casters 19 facilitate the movement of the device.

[0034] As a technical optimization of this utility model, a fixing rod 20 located between two mounting rods 2 is fixedly connected between the two horizontal bars 1.

[0035] In this embodiment, the rigidity of the device can be enhanced by two fixing rods 20, making the device more stable.

[0036] As a technical optimization of this utility model, the cross-sections of both the slot 9 and the pin 12 are rectangular.

[0037] In this embodiment, the cross-sections of the slot 9 and the pin 12 are both rectangular, which makes it easy to align the through hole 13 with the two threaded holes 10, and thus makes it easy for the first bolt 11 to pass through the through hole 13.

[0038] The working principle and usage process of this utility model are as follows: In use, first move the device to a suitable position so that the temperature measuring gun 7 and the oxygen measuring gun 8 are above the molten steel pool. Then, take out the counterweights 18 from the two placement boxes 6 and place them in the storage box 17 so that the weight of the two placement boxes 6 is less than the weight of the temperature measuring gun 7 and the oxygen measuring gun 8. Then, the weight of the temperature measuring gun 7 and the oxygen measuring gun 8 pulls the first steel wire rope 4 and the second steel wire rope 5 respectively. At the same time, the first steel wire rope 4 and the second steel wire rope 5 are guided by two sets of guide wheels 3, so that the temperature measuring gun 7 and the oxygen measuring gun 8 move downward into the molten steel. Then, the temperature measuring gun 7 and the oxygen measuring gun 8 measure the temperature and determine the oxygen in the molten steel.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
