Background Art

[0002] In the operation site of the torpedo ladle area in the iron and steel metallurgy industry, there are multiple large overhead cranes, a tipping station and its supporting equipment, a rotary car track, a locomotive transportation track, etc. The overhead crane is responsible for lifting heavy objects such as the molten iron ladle and the hot metal pouring trough, and it spans across the entire area above the workshop. The rotary car and the locomotive are respectively responsible for the steering, transfer and hauling of the molten iron ladle. Due to frequent cross-operation of processes and a complex environment where personnel are located, the safety risk is extremely high.

[0003] Existing safety measures often cannot effectively ensure the complete isolation of personnel from lifting equipment and hazardous substances, resulting in frequent accidents, posing a serious threat to the lives of employees and the normal production of enterprises. In terms of molten iron sampling, the traditional side sampling method is prone to unqualified samples such as empty samples and slag samples, which affects the accurate judgment of the molten iron composition, and further affects the operation stability and product quality of the subsequent converter process, increasing the production cost. The existing maintenance platform for the dust hood of the tipping station has limited space and poor environment, which is not conducive to the maintenance and repair of equipment.

Summary of the Invention

[0004] The purpose of the present invention is to provide an operation system for the torpedo ladle area in the iron and steel metallurgy industry to solve the problems of poor work safety and inconvenient sampling in the existing torpedo ladle area.

[0013] Among them, the lifting baffle is used to lower and give guidance for the parking position of the tank car; the slider is used to move to the best sampling area according to the scale; the sampling rod is vertically inserted downward into the hot metal ladle of the tank car through the central through hole of the slider for sampling.

[0014] Furthermore, there are two tracks, and two sampling tanks are arranged above the sampling platform, and the two sampling tanks are respectively located directly above the two tracks.

Detailed Embodiment

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The present invention provides an operating system for the torpedo ladle area in the iron and steel metallurgy industry, as Figure 1 shown. Based on a torpedo ladle operating workshop, the inner side thereof is a torpedo ladle operating area 11, in which a track 1 leading to the torpedo ladle operating area 11 is provided, and a tank car 2 is used for traveling on the track 1. A crane is provided above it.

[0024] The operating system includes an overhead corridor 3 and a sampling platform 4. The overhead corridor 3 is a mutually connected walking passage arranged along the three side wall surfaces of the torpedo ladle operating workshop, and the height of the overhead corridor 3 from the ground is at least 6 meters; a walking passage is not provided on the side wall surface of the torpedo ladle operating workshop close to the torpedo ladle operating area 11. The sampling platform 4 is extended outward from the overhead corridor 3 and is located directly above the track 1. Workers enter the sampling platform 4 through the overhead corridor 3, which can make the working process safer.

[0025] As Figure 2 shown, a lifting baffle 10 is arranged at one side edge of the sampling platform 4 and at the front end in the oncoming direction of the tank car 2, and is used to block the advancement of the tank car 2 when sampling is required, and give a reference for the parking position. The lifting baffle 10 is arranged in a lifting manner, so that it can be lowered when sampling is required to lift the tank car 2 to stop at the corresponding position, and when the tank car 2 needs to travel, the lifting baffle 10 can be raised. The realization of the lifting method, for example, the lifting baffle 10 is arranged in the form of a gate at the entrance and exit of a parking lot.

[0026] The sampling groove 12 is a strip-shaped long groove opened on the sampling platform 4 along the extension direction of the track 1, and scales are arranged along the extension direction of the edge of the sampling groove 12; tracks are arranged at both edges of the sampling groove 12.

[0027] The slider 13 is a block structure with a through hole in the center, which is arranged across the sampling groove 12, and two convex blocks are arranged at the bottom thereof, and the two convex blocks are used for sliding in the two tracks correspondingly.

[0028] The sampling rod 14 is a long rod structure, and its end is a sampling head. During use, the rod 14 is used to vertically insert into the molten iron tank of the tank car 2 through the central through hole of the slider 13, which can ensure vertical insertion into the molten iron. After sampling, the sampling head can be removed for subsequent detection.

[0029] Among them, the lifting baffle 10 is used to lower to give a guide for the parking position of the tank car 2; the slider 13 is used to move to the best sampling area according to the scale; the sampling rod 14 is used to vertically insert into the molten iron tank of the tank car 2 through the central through hole of the slider 13 for sampling.

[0030] During the sampling operation, it is required that sampling is prohibited at the edge or near the wall of the hot metal ladle because the hot metal near the ladle wall may cause composition segregation due to rapid heat dissipation (such as low carbon and silicon contents). Therefore, the recommended sampling area is at a distance of ≥1 / 3 of the radius from the ladle wall inside the hot metal ladle, where the temperature and composition of the hot metal are more uniform. During use, the lifting baffle 10 gives the parking position for the tank car 2 to stop for inspection; by setting the lifting baffle 10 at the edge of the sampling platform and cooperating with the scale on the sampling groove 12, the sampling area at a distance of ≥1 / 3 of the radius from the ladle wall inside the hot metal ladle can be quickly found; the translation slider 13 is moved to any position within the sampling area, and the adjustment and positioning of the sampling position are very convenient; then the sampling rod 14 is inserted through the through hole on the slider 13, which can ensure that the sampling rod 14 is vertically inserted into the hot metal and avoid tilting insertion along the ladle wall, resulting in the mixing of surface slag or ladle wall attachments.

[0031] In some embodiments, two tracks 1 can also be provided, and two sampling grooves 12 are arranged above the sampling platform 4, and the two sampling grooves 12 are respectively located directly above the two tracks 1. Setting multiple sampling grooves 2 corresponding to the number of tracks 1 can greatly improve the sampling efficiency.

[0032] In some embodiments, there is also a tilting track 5 parallel to the track 1, and the tilting track 5 is used for the tilting car 6 to travel; above one end of the tilting track 5 close to the hot metal mixer operation area, a dust-proof cover 9 is provided, and an exhaust pipe 7 leading to the outside of the factory building is communicated with the top of the dust-proof cover 9. The dust generated during the tilting process can be collected and treated.

[0033] In some embodiments, a maintenance platform 8 is arranged on one side of the elevated corridor 3 close to the dust-proof cover 9. The staff can enter the maintenance platform 8 through the elevated corridor 3, which can make the working process safer.

[0034] The usage method of an operation system for the hot metal mixer area in the iron and steel metallurgy industry according to the present invention is as follows:

[0035] The hot metal is poured into the hot metal ladle from the blast furnace tapping hole, and the tank car 2 travels along the track 1 towards the hot metal mixer operation area 11;

[0036] The staff enters the sampling platform 4 through the elevated corridor 3;

[0037] When sampling is required, the lifting baffle 10 is lowered;

[0038] The tank car 2 is driven to a position close to the lifting baffle 10;

[0039] According to the radius of the hot metal ladle, the optimal sampling position in the hot metal ladle is calculated, and referring to the position of the scale, the slider 13 is moved along the sampling groove 12 to a position near the optimal sampling position;

[0040] Insert the sampling rod 14 vertically downward from the central through-hole of the slider 13 into the molten iron ladle of the tank car 2 for sampling;

[0041] After sampling, take out the sampling rod 14 and conduct subsequent detection work;

[0042] Raise the lifting baffle 12, and the tank car 2 continues to move forward. After reaching the hot metal mixer operation area 11, the molten iron ladle is tilted, and the molten iron flows into the hot metal mixer for storage, and the temperature in the furnace is maintained by the combustion system.

[0043] In the lifting environment of the metallurgical industry, due to the inability of the existing technology to effectively ensure personnel safety, the accuracy of molten iron sampling, and the convenience of maintenance, the present invention realizes an absolute separation in the spatial dimension between personnel and risk factors by designing a safety corridor surrounding the workshop. This separation not only effectively avoids the direct contact between personnel and equipment such as overhead cranes, locomotives, and transfer vehicles, greatly reduces the possibility of accidents, and ensures the life safety of employees. Moreover, the elevated design of the safety corridor provides a new position and method for sampling the molten iron in the molten iron ladle. In the past, side sampling was easily interfered by many factors, resulting in inaccurate sampling results. However, sampling above the safety corridor can reduce the occurrence of unqualified samples such as empty samples and slag samples. This provides a more representative sample for the next process, which can accurately reflect the true composition of the molten iron, ensures the stability of the converter process operation, effectively reduces production costs, and improves production efficiency and product quality. In addition, the corridor is connected to the hot metal mixer operation platform, the control room platform, and the repair platform of the dust removal hood of the pouring station, expanding the repair platform space, improving the repair environment, and making the repair work more stable, safe, and smooth.
