Description

Technical Field

[0001] The utility model relates to a device for sampling a steel-making converter, belonging to the technical field of steel-making converter sampling equipment. Background Art

[0002] Converter sampling is a crucial step in the steelmaking process, impacting molten steel quality and process stability. The primary purpose of sampling is to promptly and accurately understand the composition and temperature of the molten steel, enabling the identification and timely correction of production process problems, thereby ensuring the quality and market competitiveness of steel products.

[0003] When sampling, a sampling device is required. A Chinese patent (CN116004941A) discloses a sampling vehicle for converter steelmaking. This vehicle is equipped with wheels and a drive mechanism. A positioning seat is located in the middle of the upper end of the sampling vehicle's deck, with a main rod rotatably connected to its upper portion. The main rod's ends are located above the deck, one end of which is secured with a hydraulic rod, and the other end of which is secured with a partition. A vertical slot is defined in the center of the main rod. An extension rod is movably connected to the end of the main rod remote from the hydraulic rod, and the main rod or extension rod passes through the vertical slot. A sampling device is located at the other end of the extension rod. A support sleeve is provided at the junction of the extension rod and the main rod, with its ends fixedly connected to the extension rod and the main rod, respectively. This sampling vehicle is convenient and flexible to operate, does not occupy space around the converter, and boasts a high degree of automation, allowing for unmanned on-site operation and significantly improving the safety of molten steel sampling. However, a common disadvantage of this sampling vehicle and other currently widely used sampling vehicles is that, although these sampling vehicles can perform sampling operations, they are often only able to sample samples from a single area at a time and cannot simultaneously complete the sampling of multiple different types of samples. At the same time, the sampling range of the equipment is limited, which affects the overall performance of the equipment. In order to meet the needs of production development, it is very necessary to improve the existing sampling vehicles. Utility Model Content

[0036] When it is necessary to take samples of different depths of molten steel or to take samples of different types, the rotating sampling tube 8 is driven to rotate by the rotating motor 10, the driving ring gear 11, and the rotating ring gear 12. The bottom opening of the sample storage tube 9 in the other sampling circular hole 25 of the rotating sampling tube 8 is relative to the connecting head 29, and a new sampling can be carried out.

[0037] When the rotating motor 10 rotates, the rotating motor 10 can drive the wiping metal scraper 35 to rotate synchronously, continuously wiping the scale 31 on the outside of the sampling tube body 30, preventing the molten steel from adhering to the surface of the sampling tube body 30 and obscuring the scale 31, thereby ensuring the observation effect of the scale 31.

The outer wall of the sampling tube body (30) is connected to the connector (2 The upper end of the sampling tube body (30) is flush with the upper end of the cylindrical wall of the connector (29), and the upper end of the sampling tube body (30) is tightly connected to the lower end of the sample storage tube (9) of the rotary sampling cylinder (8). A heat expansion sealing ring (33) is placed between the inner wall of the cylindrical connector (29) and the outer wall of the sampling tube body (30). The inner wall of the upper end of the heat expansion sealing ring (33) surrounds the outer side of the lower end of the sample storage tube (9). A scale (31) is provided on the outer surface of the sampling tube body (30), and a filter tip (32) is installed at the lower end of the sampling tube body (30).

6. The steelmaking converter sampling device capable of completing sampling of different samples at one time according to claim 1, characterized in that: The lower end of the motor shaft of the rotating motor (10) is connected to a vertical rotating shaft (34), and a plurality of wiping metal scrapers (35) are fixedly installed on the outer surface of the rotating shaft (34). The wiping metal scrapers (35) are rectangular plates. The length direction of the wiping metal scrapers (35) is along the length direction of the rotating shaft (34). The thickness of the outer end of the wiping metal scraper (35) is greater than the thickness of the inner end. The outer end of the wiping metal scraper (35) is tightly slidably matched with the outer wall of the sampling tube body (30) of the sampling tube (13).
