Description

Technical Field

[0001] This invention belongs to the field of silicon-calcium wire processing technology, specifically a seamless silicon-calcium wire continuous coating molding device. Background Technology

[0002] Calcium silicon silicon wire, also known as calcium silicon silicon cored wire, is an alloy cored wire used in metallurgical ladle refining. It uses a thin steel strip as the outer metal shell and is filled with calcium silicon silicon alloy powder. The steel strip is sealed with powder by a cored wire equipment. During steelmaking, it is fed into the molten steel with the help of a wire feeder to deoxidize, desulfurize, change the morphology of inclusions, improve the purity of molten steel, and improve the performance of steel.

[0003] A patent with publication number CN107245545B discloses a method for producing seamless pure calcium cored wire. The key technical points are as follows: A calcium metal rod is heated and extruded through an extruder to form a calcium metal wire with a diameter of 8.7-12.9 mm; the extruded calcium metal wire is then introduced into a vacuum coating treatment tank to uniformly coat its surface with a nano-ceramic coating; the coated calcium wire is then introduced into a curing processor and cured using a hot air device; after the coating on the surface of the calcium metal wire has cured, it is guided by guide wheels to a sizing machine for sizing; then, excess coating is cut off from the surface of the calcium wire, and it is rewound to form a seamless pure calcium cored wire with a diameter of 9-13 mm. This invention effectively ensures the steel treatment effect of the obtained cored wire, has a low scrap rate, and its production system has a simple structure, high production efficiency, low cost, and is easy to promote and use.

[0004] However, the above technologies often have the following drawbacks: existing seamless cored wire preparation mostly adopts the process of first extruding to prepare metal core wire and then coating, which cannot realize the integrated continuous forming of progressive rolling of steel strip, synchronous powder filling and circumferential extrusion closure. It is difficult to dynamically compensate for the springback and temperature rise deformation of steel strip during the forming process, resulting in poor consistency of the outer diameter of the finished product, and low equipment changeover efficiency when changing product specifications.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Reference Figure 1 - Figure 10 This invention provides two technical solutions: Example 1

[0023] A seamless silicon-calcium wire continuous coating molding device includes a frame 1, a multi-stage extrusion mechanism is installed on one side of the upper surface of the frame 1, a coating mechanism is installed in the middle of the upper surface of the frame 1, a groove is opened on the upper surface of the frame 1, and the multi-stage extrusion mechanism is set in two symmetrical groups. The multi-stage extrusion mechanism includes a support rod 2, the bottom of which is fixedly installed on one side of the upper surface of the frame 1. Both ends of the support rod 2 are fixedly connected to A connecting plates 3. One end of the A connecting plate 3 is equipped with an A telescopic rod 4, and one end of the A telescopic rod 4 is fixedly connected to an A adjusting plate 5. An A drive motor 6 is mounted on the surface of the A adjusting plate 5. Two sets of A drive motors 6 are symmetrically arranged, and the output end of each A drive motor 6 is splinedly connected to an A turntable 7. The surface of the A turntable 7 has an A embedding groove 8. An extrusion shell 9 is installed inside the A embedding groove 8 on one set of A turntables 7. The A turntables 7 in the two sets of multi-stage extrusion mechanisms have different diameters. This differentially arranged arrangement of A turntables 7 allows for multiple passes of the flat steel strip. Progressive rolling gradually bends and rolls the flat steel strip into an open round tube blank, avoiding tearing damage caused by a single strong bending. The A telescopic rod 4 can drive the A adjusting plate 5 and the A turntable 7 to move radially, flexibly adjusting the extrusion gap of the extrusion shell 9 to adapt to the forming requirements of steel strips of different specifications. The spring assembly on the outside of the A connecting plate 3 can provide elastic buffering force, adaptively buffering the load fluctuations caused by the deformation of the steel strip during the rolling process. In addition, the extrusion shell 9 integrates a heating ring 10, which can control the temperature of the steel strip during forming, improve the plasticity of the steel strip, ensure the roundness of the tube blank, and provide a tube blank with a stable shape for the subsequent circumferential closing process of the coating mechanism, reducing forming defects from the source and ensuring continuous and stable steel strip conveying. Example 2

[0024] A heating ring 10 is installed inside the extrusion shell 9, and an A spring 11 is sleeved on the outside of the A telescopic rod 4. The two ends of the A spring 11 are respectively connected to the end joints of the A connecting plate 3 and the A adjusting plate 5. The heating ring 10 can uniformly heat the extrusion shell 9 and the contact steel strip, improve the plasticity of the steel strip, reduce the springback stress during roll forming, and reduce defects such as cracking and wrinkling of the steel strip. The A spring 11 can provide elastic buffering when the A telescopic rod 4 adjusts the extrusion position. It can adaptively absorb the load fluctuations generated during the roll forming process of the steel strip, buffer the impact load, maintain a stable roll forming pressure between the extrusion shell 9 and the steel strip, and at the same time, cooperate with the A telescopic rod 4 to realize flexible fine adjustment of the extrusion spacing, ensuring a smooth and continuous multi-pass progressive roll forming process.

[0025] The covering mechanism includes a B connecting plate 12, the bottom of which is mounted on the middle of the upper surface of the frame 1. A B telescopic rod 13 is mounted on one end of the B connecting plate 12, and a B adjusting plate 14 is fixedly connected to one end of the B telescopic rod 13. A B drive motor 15 is mounted on the surface of the B adjusting plate 14, and a B turntable 16 is splined to the output end of the B drive motor 15. The B turntables 16 are arranged in two symmetrical sets, and B embedding grooves 17 are opened on the surface of the B turntables 16. A B spring 18 is sleeved on the outside of the B telescopic rod 13, and the two ends of the B spring 18 are respectively connected to the end joints of the B connecting plate 12 and the B adjusting plate 14. The two symmetrically arranged B turntables 16 can perform circumferential pressure closure on the open round tube blank that has been conveyed to the position, thus covering the steel strip. The ends are directly extruded and bonded to form a metal shell without longitudinal overlap, simultaneously sealing the calcium silicate powder inside the tube. The B telescopic rod 13 can drive the B adjusting plate 14 and the B turntable 16 to move radially, flexibly adjusting the extrusion distance between the two sets of B turntables 16 to adapt to the coating molding requirements of calcium silicate wires with different diameters. The B spring 18 provides elastic buffering during the extrusion operation, which can adaptively offset the dimensional fluctuations and impact loads during tube blank transportation, ensuring that the B turntable 16 applies a continuous and stable closing extrusion force to the tube blank. The B embedded groove 17 facilitates quick disassembly and replacement of molding molds of different specifications, improves equipment changeover efficiency, realizes continuous seamless coating operation, and effectively solves the problems of joint cracking and core powder leakage that are prone to occur in traditional overlapping structures.

[0026] Both turntable A 7 and turntable B 16 are rotatably connected to a connecting rod 19 via bearings at their middle parts, and an adaptive elastic pre-tightening mechanism is installed at one end of the connecting rod 19.

[0027] The adaptive elastic preload mechanism includes a dual-axis electric push rod 20. Both ends of the dual-axis electric push rod 20 are equipped with fixed plates 21. The adaptive elastic preload mechanism is configured in multiple groups, with one group located inside the support rod 2. The side ends of the fixed plates 21 are installed inside the support rod 2. The dual-axis electric push rod 20 has sleeve rods 22 on both sides, with guide rods 23 inserted into both ends of each sleeve rod 22. One end of each guide rod 23 is fixedly connected to a rotating component A 24. Two symmetrical groups of rotating components A 24 are distributed on both sides of the dual-axis electric push rod 20. One end of each rotating component A 24 is fixedly connected to a spring C 25, and one end of each spring C 25 is fixedly connected to a rotating component B 26. One end of each rotating component B 26 is fixedly connected to the surface of the fixed plate 21. A movable plate 27 is fixedly connected to the side end of each rotating component A 24. The surface of the movable plate 27 is connected to the connecting rod. The end face of 19 is fixedly connected. The dual-axis electric push rod 20 is driven by the outer diameter signal of the wire fed back by the control sensor 30, which pushes the fixed plate 21 and the guide assembly to move precisely along the sleeve rod 22. Then, through the A rotating part 24, B rotating part 26 and C spring 25, the moving plate 27 is driven to adjust the connecting rod 19 in linkage, and the roller gap of A turntable 7 and B turntable 16 is finely adjusted in real time. The guiding cooperation between the sleeve rod 22 and the guide rod 23 ensures stable linear movement in the transmission direction. The C spring 25 provides continuous elastic preload during the adjustment process, adaptively compensating for the dimensional deviation caused by the cold working springback of the steel strip and the temperature rise of continuous forming. It eliminates the need for frequent machine stops to manually calibrate the roller gap, accurately locks the outer diameter tolerance of the finished silicon calcium wire, avoids feeding jamming and wire breakage caused by uneven wire thickness, and ensures the consistency of outer diameter dimensions in long-line continuous production.

[0028] Both sides of the frame 1 are hinged with upright plates 28 by angle steel. One end of the upright plate 28 is fixedly connected to the top plate 29, and one set of adaptive elastic pre-tightening mechanisms is installed at the bottom of the top plate 29.

[0029] Control sensors 30 are installed on the top of both the A connecting plate 3 and the top plate 29, and the control sensors 30 are electrically connected to the adaptive elastic pre-tightening mechanism. A frame 31 is fixedly connected to the edge of the upper surface of the top plate 29, and an A storage box 32 is installed inside the frame 31. A B storage box 33 is fixedly connected to the side of the A connecting plate 3. Both the A storage box 32 and the B storage box 33 have drain pipes 34 installed at their bottoms. The control sensors 30 collect real-time parameters such as the outer diameter and forming deformation of the silicon-calcium wire tube blank online and convert them into electrical signals, which are then transmitted to the adaptive elastic pre-tightening mechanism. The mechanism enables closed-loop dynamic adjustment of the roller gap; the frame 31 provides reliable positioning for the A storage box 32, reducing positional deviation caused by continuous equipment vibration; the A storage box 32 and the B storage box 33 are arranged separately, enabling continuous graded feeding of silicon-calcium powder; the drain pipe 34 can accurately guide the alloy powder into the internal cavity formed by the rolling of the steel strip, matching the process rhythm of the progressive forming of the steel strip, ensuring that the filler inside the pipe is filled and uniform, effectively preventing material shortage and core eccentricity, improving the stability of the finished silicon-calcium wire filler, and ensuring stable deoxidation and desulfurization effects during steelmaking wire feeding operations.

[0030] Shrink rings 35 are installed on the upper surface of the frame 1 near the coating mechanism. There are two sets of shrink rings 35, which are arranged sequentially along the conveying direction of the calcium silicate wire. They can perform radial shrinking and shaping of the tube body after it has been closed by turntable B 16, further compacting the steel strip joint and eliminating local bulges and contour distortion of the tube blank after coating. The inner hole of the shrink ring 35 is matched with the outer diameter of the finished wire, which plays a role in radial limiting and rounding correction of the tube body, helping the steel strip to maintain a round shape, suppressing the rebound and expansion of the tube after forming, consolidating the seamless closure effect, and preventing the coating joint from reopening and leaking powder. The two sets of sequentially arranged structures can achieve smooth and gradual shrinkage, preventing the wire from being crushed and uneven in wall thickness caused by a single large deformation, improving the outer circle accuracy and structural integrity of the finished calcium silicate wire, and ensuring smooth subsequent traction and conveying without jamming.

[0031] A support plate 36 is installed on the other side of the upper surface of the frame 1. A C-drive motor 37 is installed at one end of the support plate 36. The output end of the C-drive motor 37 is splined to a ring frame 38. The support plate 36 provides a stable support base for the C-drive motor 37 and the ring frame 38. The C-drive motor 37 can drive the ring frame 38 to rotate at a uniform speed. The ring frame 38 is used to store the finished silicon-calcium wire, realize the continuous winding of the finished silicon-calcium wire, and the winding speed can match the line speed of the front-end forming conveyor. It maintains the stable tension of the wire in the entire production line and prevents the silicon-calcium wire from stretching and thinning, loosening and messing up during the winding process. It ensures that the finished wire roll is neat and tidy, which is convenient for subsequent transfer and wire feeding.

[0032] The inner wall of the frame 1 has a sliding groove for a sliding block 39. A collection box 40 is installed inside the slider 39, and a pulley 41 is installed at the bottom of the collection box 40. The slider 39 and the inner groove of the frame 1 cooperate with each other and work together with the bottom pulley 41 to reduce the resistance of the pull-out movement, so that the collection box 40 can be easily pulled out along the groove of the frame 1 for regular cleaning and material dumping. The collection box 40 is arranged below the forming conveyor path and can catch the excess silicon calcium powder spilled from the sluice tube 34 during the forming process and the metal debris falling off during the shaping process, preventing powder from scattering and accumulating inside the frame 1, preventing dust from jamming the rotating and sliding parts, reducing equipment wear and jamming failures. The pull-out structure does not require the overall disassembly of the frame 1, making powder cleaning operations convenient and efficient, improving the working environment of the equipment, and reducing material waste.

[0033] Working Principle: Silicon-calcium alloy powder is stored in storage boxes A (32) and B (33). The powder is continuously conveyed downwards through the bottom drain pipe 34 to the steel strip forming channel. The flat steel strip is fed into the multi-stage extrusion mechanism and coating mechanism on the frame 1. The steel strip enters the multi-stage extrusion mechanism on one side of the frame 1. Drive motor A (6) drives turntable A (7) to rotate. Multiple turntables A (7) of different diameters, in conjunction with extrusion shell 9, progressively roll the steel strip. Telescopic rod A (4) and spring A (11) adjust the radial position of extrusion shell 9, gradually bending and rolling the flat steel strip into an open cylindrical tube blank. The heating ring 10 inside extrusion shell 9 helps regulate the steel strip forming temperature. The rolled open cylindrical tube blank is conveyed to the coating mechanism in the middle of the frame 1. Drive motor B (15) drives turntable B (16) to rotate. Telescopic rod B (13) and spring B (18) control the radial pressing of turntable B (16), extruding the tube blank from circumference to all sides, closing the ends of the steel strip, forming a seamless cylindrical tube without longitudinal overlap, and simultaneously sealing the silicon-calcium powder. Inside the tube, the A turntable 7 and B turntable 16 are connected to an adaptive elastic pre-tightening mechanism via a connecting rod 19. The control sensor 30 collects the outer diameter signal of the calcium silicate wire in real time, and the electrical signal is transmitted to the dual-axis electric push rod 20, sleeve rod 22, and guide rod 23 for guidance. The C spring 25 provides elastic pre-tightening force, which drives the moving plate 27 to finely adjust the gap between the connecting rod 19 and the turntable rollers, automatically compensating for the dimensional deviation caused by the cold working springback of the steel strip and the thermal expansion caused by the forming temperature rise, locking the outer diameter tolerance of the finished product. The seamless calcium silicate wire after forming continues to be conveyed forward, passing through two sets of shrink rings 35 on the frame 1 near the coating mechanism, which further refine the outer contour of the wire to ensure roundness. The C drive motor 37 drives the ring frame 38 to rotate, pulling the calcium silicate wire to be continuously conveyed forward, realizing continuous and uninterrupted material output. The powder and steel strip edge debris that fall during the forming process fall into the collection box 40 on the slider 39 in the inner slide groove of the frame 1. The collection box 40 has a pulley 41 at the bottom, which can be pulled out and the waste can be cleaned periodically.
