Description

Technical Field

[0001] This utility model relates to the field of metal detection technology, specifically a spectral sampling mold for detecting the composition of silicon-manganese alloy melt. Background Technology

[0002] As a core auxiliary raw material in the steel industry, silicon-manganese alloy requires precise control of its composition (14%-22% silicon, 65%-75% manganese, and less than 0.3% phosphorus and sulfur impurities) to ensure steel quality. To monitor the smelting process in real time, the industry uses spectral analysis technology to detect the composition of the melt. This technology requires converting the 1400-1600℃ high-temperature melt into a solid sample with a smooth surface and no internal defects. Therefore, spectral sampling molds for silicon-manganese alloy melt composition detection have emerged. These molds are mostly made of heat-resistant cast iron or high-alumina refractory materials. They receive the melt through a disc-shaped cavity with a diameter of 18-25mm and a thickness of 6-8mm. The melt is cooled and solidified within 5-10 minutes by its own heat dissipation. This mold becomes a key carrier connecting the "melt" and "spectral detection". Without a qualified mold, spectral analysis cannot be implemented and the smelting process is difficult to adjust dynamically.

[0003] However, the current mainstream molds have obvious efficiency shortcomings and cannot meet the real-time requirement of steelmaking production that "one batch of component data is needed every 15 minutes". On the one hand, most molds are single-cavity designs, which can only pour one sample at a time, and it is necessary to wait 8-12 minutes for the sample to cool completely before demolding. During this period, it is impossible to take another sample, and the sampling interval of a single batch far exceeds the requirements.

[0004] To address this issue, the present invention provides a spectral sampling mold for detecting the composition of silicon-manganese alloy melt, thereby solving the aforementioned problems. Utility Model Content

[0014] This invention provides a spectral sampling mold for detecting the composition of silicon-manganese alloy melt. Compared with the prior art, it has the following advantages: (1) The silicon-manganese alloy melt composition detection spectral sampling mold, through the setting of the rotating table and its matching positioning components in the rotating cooling structure, can simultaneously assemble multiple mold structures on the rotating table work surface. With the help of the rotating power of the rotating table and the precise locking of the positioning components, the orderly alternation of different mold structures between the melt sampling station, cooling station, demolding and detection station can be realized, which completely solves the efficiency defects of the existing single cavity mold, meets the real-time requirements of steelmaking production, and greatly improves the continuity and overall efficiency of sampling operations.

[0015] (2) The silicon-manganese alloy melt composition detection spectral sampling mold, through the coordinated arrangement of the lower water tank, pusher plate, hydraulic top in the rotary cooling structure, and the heat exchange plate integrated in the lower mold in the mold structure, the hydraulic top can drive the pusher plate to squeeze the cooling liquid in the lower water tank upward, so that the cooling liquid can quickly and fully contact the heat exchange plate, and the heat of the melt inside the lower mold cavity can be efficiently transferred to the cooling liquid through the heat exchange plate, which significantly shortens the melting solidification time.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 A spectral sampling mold for detecting the composition of silicon-manganese alloy melt, comprising: The rotary cooling structure 1 has the ability to rotate continuously, and multiple mounting positions are equidistantly arranged along the axis at the edge of the upper surface; Mold structure 2 is assembled and positioned on the upper surface of the rotary cooling structure 1. The rotary cooling structure 1 includes a rotary table 11, which includes a base for support, a power device for driving rotation, a worktable for carrying objects, and a transmission mechanism and positioning components for achieving smooth transmission and precise positioning. The worktable of the rotary table 11 is open downward at the assembly position of the mold structure 2, and a C-shaped upward-opening lower water tank 12 is sealed and moved relative to the lower end of the open end. The lower water tank 12 is connected to the base of the rotary table 11 for support and positioning with a support rod. The notch of the lower water tank 12 corresponds to the melt sampling station. The internal shape of the lower water tank 12 is matched with a water pusher 13 that moves up and down. The lower surface of the water pusher 13 is fixed to the output end of a plurality of hydraulic tops 14 that are bolted to the lower surface of the lower water tank 12, thereby driving the up and down movement of the water pusher 13. The mold structure 2 includes a lower mold 21, which is positioned at a pre-set assembly position on the worktable surface of the rotary table 11. A heat exchange plate 211, which contacts the cooling liquid, extends integrally from the lower surface of the lower mold 21 into the assembly position. At the upper end of the lower mold 21, a hinge assembly is used to rotate it with the first upper mold 22 and the second upper mold 23 near the axis of the rotating cooling structure 1 and on an adjacent side. This allows the first upper mold 22 and the second upper mold 23 to perform a mold closing operation on the lower mold 21. The hinge ends of the hinges connected to the first upper mold 22 and the second upper mold 23 extend and transition to form a first closing mechanism. The first hinge shaft 242 and the second hinge shaft 244 are configured such that the shaft end of the first hinge shaft 242 is engaged with the toothed belt pulley set 241 and the shaft of the drive motor 24 for transmission, and the shaft end of the second hinge shaft 244 is engaged with the bevel gear set 243 and the shaft of the drive motor 24 for transmission. Thus, under the drive of the drive motor 24, and with the transmission of the toothed belt pulley set 241 and the transmission reversal of the bevel gear set 243, the first hinge shaft 242 and the second hinge shaft 244 can alternately close the lower mold 21. The drive motor 24 is bolted to the worktable surface of the rotary table 11.

[0021] During operation, the rotary cooling structure 1's rotary table 11 is first activated, driving the worktable to rotate smoothly and rotate one mold structure 2 to the melt sampling station. The positioning component locks to ensure precise alignment. Then, the drive motor 24 on the rotary table 11 is activated, driving the first and second hinge shafts to rotate through the toothed belt pulley group 241 and the bevel gear group 243 respectively. This causes the first upper mold 22 to flip downwards and the second upper mold 23 to flip upwards, forming a closed cavity. Then, 1400-1600℃ silicon-manganese alloy melt is injected through the injection hole. After the melt is injected, the positioning component is unlocked, and the rotary table 11 rotates the mold to the area of ​​the lower water tank 12, ensuring that the heat exchange plate 211 at the bottom of the lower mold 21 is within the cooling range. Then, the hydraulic top 14 of the lower water tank 12 pushes the pusher plate 13 upwards, allowing the coolant to contact the heat exchange plate 211 to accelerate the cooling of the melt. After the second mold is injected, the hydraulic top 14 drives the pusher plate 13 to reset, and the mold rotates to the cooling area to repeat the cooling operation to achieve circulating heat exchange. After the sample has cooled to the required standard, the drive motor 24 rotates in reverse, causing the first upper mold 22 to flip upward and the second upper mold 23 downward to open the mold. The rotary table 11 moves the mold containing the solidified sample to the demolding and testing station, while the empty mold is moved to the sampling station. The process of mold closing, liquid injection, displacement, and cooling is repeated to achieve continuous operation. Finally, the staff demolds the sample at the demolding and testing station and sends it for spectral analysis.

[0022] In summary, by setting up the rotary table 11 and its matching positioning components in the rotary cooling structure 1, multiple sets of mold structures 2 can be assembled simultaneously on the worktable surface of the rotary table 11. With the rotational power of the rotary table 11 and the precise locking of the positioning components, different mold structures 2 can be switched in an orderly manner between the melt sampling station, cooling station, demolding station, and inspection station. This completely solves the efficiency defects of existing single-cavity molds, meets the real-time requirements of steelmaking production, and significantly improves the continuity and overall efficiency of sampling operations. Through the coordinated arrangement of the lower water tank 12, water pusher 13, hydraulic jack 14 in the rotary cooling structure 1, and the heat exchange plate 211 integrated into the lower mold 21 in the mold structure 2, the hydraulic jack 14 can drive the water pusher 13 to push the cooling liquid in the lower water tank 12 upwards, thus... The coolant quickly and fully contacts the heat exchange plate 211, efficiently transferring the heat of the melt inside the cavity of the lower mold 21 to the coolant, significantly shortening the melt cooling and solidification time. Through the transmission structure of the drive motor 24, toothed belt pulley group 241, bevel gear group 243, and first hinge shaft 242 and second hinge shaft 244 in the mold structure 2, when the drive motor 24 is running, it can drive the first hinge shaft 242 to rotate through the toothed belt pulley group 241, and drive the second hinge shaft 244 to rotate in the opposite direction through the bevel gear group 243. This achieves the reverse alternating mold closing and opening operations of the first upper mold 22 downward and the second upper mold 23 upward. With the cooperation of the staff, after the mold is quickly removed, the mold structure 2 can quickly enter the next liquid injection and sampling operation.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0024] Working Principle: During operation, the rotary table 11 in the rotary cooling structure 1 is first started. Its power unit drives the worktable to rotate smoothly around the axis as the origin, rotating the mold structure 2 on one of the assembly positions to the melt sampling position. At this time, the positioning component of the rotary table 11 locks the equipment to ensure that the mold structure 2 is accurately aligned. Subsequently, the drive motor 24, which is bolted to the worktable of the rotary table 11, is started. Its shaft drives the first hinge shaft 242 to rotate through the toothed belt pulley set 241, driving the first upper mold 22 to flip downward around the hinge assembly. At the same time, the shaft drives the second hinge shaft 244 to rotate in the opposite direction through the bevel gear set 243, causing the second upper mold 23 to flip upward around the hinge assembly. Through the downward movement of the first upper mold 22 and the upward movement of the second upper mold 23, the rotation is complete. The alternating actions work together to complete the opening and closing of the lower mold 21, forming a closed and suitable cavity. Then, using the injection holes on the upper surface of the first upper mold 22 or the second upper mold 23, molten silicon-manganese alloy at 1400-1600℃ is injected into the closed cavity. After injection, the positioning components of the rotary table 11 are unlocked, and the power unit drives the worktable to rotate, moving the lower mold 21 containing the injected molten material to the area corresponding to the lower water tank 12. This ensures that the heat exchange plate 211 at the bottom of the lower mold 21 is completely within the cooling range of the lower water tank 12. Then, the hydraulic pusher 14 in the lower water tank 12 is activated, pushing the pusher plate 13 to slide upward along the inner wall of the lower water tank 12, squeezing the cooling liquid in the tank, so that the cooling liquid quickly spreads to the bottom of the lower mold 21 and the heat exchange plate 211. 11. Contact is made (the heat exchange plate 211 extends into the through-assembly position of the rotary table 11, making full contact with the coolant). The heat of the melt inside the cavity of the lower mold 21 is efficiently transferred to the coolant through the heat exchange plate 211, which greatly accelerates the cooling and solidification of the melt, ensuring that the melt forms a solid sample with a smooth surface and no internal defects. After the second mold structure 2 completes the liquid injection, the hydraulic top 14 drives the pusher plate 13 to reset downwards. Then, the second mold structure 2 moves to the area corresponding to the lower water tank 12 under the drive of the rotary table 11, and then the above cooling operation is performed again to form a circulating contact heat exchange of the coolant. When the sample is cooled to meet the requirements of spectral detection, the drive motor 24 rotates in reverse, driving the first hinge shaft 242 to rotate in reverse through the toothed belt pulley group 241. The rotation causes the first upper mold 22 to flip upward around the hinge assembly. Simultaneously, the machine shaft drives the second hinge shaft 244 to rotate in the opposite direction via the bevel gear set 243, driving the second upper mold 23 to flip downward around the hinge assembly. Through the alternating upward movement of the first upper mold 22 and the downward movement of the second upper mold 23, the mold opening operation is completed. At this time, the rotary table 11 continues to drive the worktable to rotate, moving the mold structure 2 containing the solidified sample to the demolding and testing station. At the same time, the next empty mold structure 2 is moved to the sampling station. The above mold closing, liquid injection, rotation and displacement, and cooling processes are repeated to achieve continuous and uninterrupted sampling operations. At the demolding and testing station, the operator demolds the cooled sample, and then the sample can be sent to the spectroscopic detection equipment for component analysis.
