Description

Technical Field

[0001] The utility model relates to material transportation of steelmaking equipment, in particular to a temperature-adjusting cold material transfer device of a converter argon blowing station. Background Art

[0002] In the continuous casting process of steel production, achieving stable casting at a constant temperature and speed is crucial to ensuring product quality and production efficiency. Achieving this goal relies on the converter's ability to provide a stable molten steel temperature. To improve the first pour rate and reduce various consumption indicators, such as steel material, the converter itself places high demands on operator precision. This requires precise control of the endpoint temperature and composition to meet the tapping requirements of the steel being produced. If the converter's endpoint temperature is too high, the molten steel temperature must be adjusted at the argon blowing station after tapping to ensure the appropriate temperature for continuous casting, thereby stabilizing the continuous casting process.

[0003] The traditional method of temperature control in argon blowing stations uses a simple temperature control silo, utilizing the short-length scrap steel produced during the steel rolling process as the temperature control cold material. Specifically, a steel bar cutting machine is used to manually cut the steel into steel bar heads less than 10 cm in length, which are then hoisted into the simple silo by an overhead crane for molten steel temperature control. However, this traditional method has many drawbacks. First, the scrap steel pool and the argon blowing station are usually not in the same span, which makes the transfer distance of the temperature control cold material longer, increasing the time and cost of material transportation. Second, the efficiency of manually transporting the temperature control cold material by the overhead crane is extremely low. It not only consumes a lot of manpower and time resources, but also, when the overhead crane is busy transporting the temperature control cold material, it affects other normal production operations in the workshop, reducing the efficiency and continuity of the entire production process, and failing to meet the requirements of modern steel production for an efficient and stable production rhythm.

[0029] In order to make the purpose, technical solution and beneficial effects of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0030] like Figure 1-7As shown in the specific embodiment, the converter argon blowing station temperature-controlled cold material transfer device includes a travel unit 1; each travel unit 1 is provided with a support frame 105 on top, which is used to support a hopper unit 3; the hopper unit includes a hopper 301 located between the two support frames 105, and the hopper 301 is rotatably connected to the support frames 105 on both sides. A conveyor line unit 2 is provided above the travel unit 1 and below the hopper 301. The conveyor line unit 2 includes a discharge belt line 201 hinged at the middle portion to the travel unit 1; the discharge belt line 201 is rotatably connected to the travel unit 1 via a conveyor line support shaft 204; it is used to receive and transport the material discharged from the hopper 301. A T-shaped bracket 202 is provided at the bottom of the discharge belt line 201, and an adjustable height foot cup 203 is fixedly connected to the lower end of the T-shaped bracket 202 for adjusting the angle of the discharge belt line to adapt to different work needs.

[0031] Example 1: The converter argon blowing station temperature-controlled cold material transfer device also includes a belt conveyor unit 4, which includes a belt conveyor body 401. A belt 403 is hinged to the top of the belt conveyor body 401. The hinged design allows the belt to adjust its working angle according to actual needs. The end of the belt 403 is hinged to the belt conveyor body 401 through an articulated seat, so that the belt can swing freely within a certain range, thereby adapting to different unloading or loading height requirements. In order to ensure that the belt 403 can maintain the correct inclination angle to facilitate the effective transportation of materials, a belt conveyor hydraulic cylinder 402 is also provided on the belt conveyor body 401 to assist in supporting the belt 403 so that the starting end of the belt 403 is higher than the end. The cylinder seat of the belt conveyor hydraulic cylinder 402 is hinged to the belt conveyor body 401, and the cylinder rod end of the belt conveyor hydraulic cylinder 402 is hinged to the bottom of the belt 403.

[0032] Example 2: The travel unit includes a travel chassis 101 with travel wheels 103 mounted on its bottom. These wheels are directly driven by an electric motor and equipped with an encoder to precisely monitor travel speed and position. This provides a solid mobile foundation for the converter argon blowing station's temperature-controlled cold material transfer device, ensuring the equipment can successfully complete material transfer tasks under various conditions.

[0033] Example 3: The hopper 301 is mounted on the support frame 105 via the hopper tilting shaft 305, allowing the hopper to rotate relative to the traveling unit to adjust the hopper angle, facilitate the loading and dumping of scrap steel, and adapt to different operational requirements. Specifically, in order to achieve precise angle adjustment, a gear 2 306 is provided on the outer surface of the hopper tilting shaft 305 on one side of the hopper 301, and a key connection is used to ensure that the two rotate synchronously. A hydraulic motor 104 is fixedly mounted on the support frame 105, and a gear 1 107 is mounted on the output shaft of the hydraulic motor 104 via a key. The gear 1 107 is meshed and connected with the gear 2 306, forming a set of efficient transmission systems. When the hydraulic motor 104 is started, the gear 1 107 is driven to rotate, thereby driving the meshed gear 2 306 to rotate, ultimately achieving precise control of the hopper angle. This design not only simplifies the structure, but also improves the response speed and reliability of the system.

[0034] In addition, a rotating shaft pressure cover 106 is installed on the hopper turning shaft 305 to fix the hopper turning shaft to prevent the turning of the hopper turning shaft from being separated. The rotating shaft pressure cover 106 fastener is installed on the support frame to achieve split setting and convenient disassembly and replacement.

[0035] Example 4: To facilitate loading and unloading, a spacious loading port 302 is located at the top of the hopper 301, ensuring smooth entry of scrap steel. A discharge port 303, located at one side of the hopper's bottom, provides a convenient unloading channel for the scrap steel. Of particular note is a vibrator 304 located at the bottom of the hopper 301. This vibrator produces a gentle vibration during operation, helping the scrap steel to slide smoothly out of the discharge port 303, preventing blockage and significantly improving unloading efficiency.

[0036] Example 5, purpose of the belt conveyor unit 4:

[0037] Unloading state: The end of the discharging belt line 201 of the conveyor line unit 2 is connected to the belt conveyor unit 4, so that the scrap steel can be lifted and transported to the converter through the belt 403 to complete the molten steel temperature control work.

[0038] Loading state: The belt conveyor unit 4 is used for loading, and the scrap steel is lifted and loaded into the hopper through the belt conveyor unit 4 until the hopper is full.

[0039] The following describes the use of the present invention in conjunction with the accompanying drawings and technical solutions:

[0040] S1. When the converter argon blowing station needs scrap steel for molten steel temperature adjustment, the transfer device is manually pulled to the scrap steel storage location and fixed.

[0041] S2. Manually transfer the belt conveyor to its position, control the belt head of the belt conveyor to correspond to the loading port of the transfer device, and rotate the driving gear 2 by controlling the hydraulic motor of the hopper so that the hopper can rotate a certain angle along the hopper turning axis to facilitate the docking of the loading port and the belt conveyor head.

[0042] S3. Manually load the belt conveyor unit with a forklift or overhead crane, and lift the scrap steel into the hopper through the belt conveyor unit until the hopper is full.

[0043] S4. Manually pull the transfer device to the converter argon blowing station. By controlling the hydraulic motor to rotate the driving gear 2, the hopper can be rotated along the hopper turning axis by a certain angle, so that the hopper discharge port is tilted downward, and the angle of the scrap steel in the hopper can be poured out.

[0044] S5. Scrap steel continuously flows out of the hopper outlet onto the conveyor line unit. A vibrator is installed at the bottom of the hopper to facilitate the smooth flow of scrap steel out of the outlet and onto the conveyor line unit. A belt conveyor is installed at the end of the conveyor line unit to connect the scrap steel. The belt conveyor lifts the scrap steel output from the conveyor line unit to a certain height (directly conveying the scrap steel to the converter argon blowing station) and then transports the scrap steel into the converter. This completes the temperature control of the molten steel at the converter argon blowing station.

[0045] The utility model completes the material transfer between the argon blowing station behind the furnace and the scrap steel pool. A movable silo is required. The crushed material is transported to the argon blowing station for temperature adjustment through the transfer device, which meets the temperature adjustment requirements of the converter, provides accurate molten steel temperature for continuous casting, stabilizes the continuous casting production rhythm, and realizes constant temperature and constant speed casting.
