Description

Technical Field

[0001] This invention relates to the field of steel plate forming technology, and more specifically, to a high-performance steel plate precision forming equipment and its intelligent full-process processing technology. Background Technology

[0002] Steel sheet forming technology is a fundamental processing step in fields such as machinery manufacturing, automotive industry, aerospace, and construction. With the increasing demand from modern industry for lightweight, high-strength, and complex structures, precision forming technology for high-performance steel sheets has become a research hotspot. Precision forming equipment must not only ensure the geometrical accuracy and surface quality of the steel sheet, but also consider forming efficiency, material utilization, and the stability of the finished product's mechanical properties.

[0003] Currently, existing precision forming equipment and processing technology for steel plates, especially in processes involving the flow of liquid metal such as steel plate casting or hot forming, still have the following technical problems: First, during the casting or fluid filling stage, the flow channel design of traditional equipment often has structural dead corners, sharp corners or steps. This makes it easy for liquid metal (such as molten steel) to cause flow separation, eddy stagnation or even air entrapment during the flow process. The accumulation of fluid in dead corners not only increases the risk of oxide inclusions, but may also form internal defects such as cold shuts and shrinkage porosity after solidification, which seriously affects the density and mechanical properties of steel plates. Secondly, existing equipment is insufficient in controlling inclusions in molten steel (such as steel slag and non-metallic impurities). Most designs rely on static filter screens or simple baffle structures. Although these can intercept impurities, the filter elements are prone to clogging and cannot adaptively adjust the flow channel opening according to changes in the incoming flow rate and pressure. When the flow rate increases, the fixed opening of the filter structure will create a significant throttling effect, resulting in excessively high local flow velocity, high liquid level, or turbulence, which further deteriorates the filling stability. When the flow rate is low, an excessively large flow channel opening may reduce the filtration efficiency. This contradiction between filtration effect and smooth flow limits the improvement of molding quality. For example, patent application number 202110180972.3 discloses a production system and process for metal-based composite ceramic steel plates, which details the complete process flow and supporting equipment for steel plate forming. The casting pipe is an indispensable core component in this prior art. However, in practical applications, this casting pipe exposes the aforementioned typical defects: the slag removal device inside is essentially a slag removal rod with a fixed opening, which can only statically intercept the molten slag floating on the molten steel. It cannot adaptively adjust according to the instantaneous changes in the inflow rate and pressure. When the molten steel flow rate is small, in order to maintain the necessary slag interception effect, the bottom end of the slag removal rod has to extend further into the rectangular chute, which has significantly reduced the effective flow cross-section. Once the flow rate increases, the slag removal rod with a fixed depth immediately becomes a strong throttling element. According to the principles of fluid mechanics, the flow channel cross-section... The sudden contraction of the flow path leads to a sharp increase in local flow velocity and significant pressure loss, which in turn causes the liquid level to rise and violent turbulence to occur. During this process, air and oxide film are easily drawn into the molten steel, which seriously deteriorates the stability of the filling process. What is even more unfavorable is that the chute has a rectangular cross-section, and its right-angled edges form typical dead flow corners and geometric sharp corner areas. When the molten steel flows through these areas, boundary layer separation and eddy current retention are likely to occur. The liquid metal retained in the dead corners cannot be effectively replaced for a long time, which not only aggravates the formation of oxide inclusions, but also greatly increases the risk of internal defects such as cold shuts and shrinkage porosity after solidification. It can be seen that the existing technology fully embodies the inherent contradiction between filtration effect and smooth flow in traditional equipment with fixed baffle filter structure and rectangular flow channel design, making it extremely inconvenient to use and difficult to meet the stringent requirements of precision forming of high-purity and high-density steel plates. Summary of the Invention

[0014] To achieve the above objectives, the present invention provides an intelligent full-process processing technology for high-performance steel plate precision forming equipment, comprising the following steps: S1. Steel smelting and transfer: Steel billets are added to the steel smelting furnace to produce molten steel at 1450-1700℃, and the molten steel is transferred to the casting ladle through the intermediate ladle; S2.

[0015] Beneficial effects This invention provides a high-performance steel plate precision forming equipment and its intelligent full-process processing technology, which has the following beneficial effects: This high-performance steel plate precision forming equipment and its intelligent full-process processing technology, through the setting of the semi-circular continuous curved surface configuration of the casting concave plate, can eliminate the structural dead corners and geometric sharp corners of traditional rectangular flow channels, guide the molten steel to spread smoothly along the wall surface, and effectively suppress flow separation, eddy stagnation and air entrapment. Through the coordinated setting of the first blocking vertical plate, the second blocking vertical plate and the telescopic blocking component, steel slag and non-metallic inclusions can be forcibly intercepted under the mechanical filtration action of the blocking column. With the help of the fluid dynamic pressure effect, the opening of the baffle can be adaptively adjusted to increase the flow cross-sectional area at high flow rates to ensure smooth flow and avoid throttling and turbulent air entrapment. At low flow rates, effective interception is maintained, thus taking into account both filtration efficiency and filling stability.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 In existing technology, the slag removal device installed inside the casting pipe is essentially a slag removal rod with a fixed opening. It can only statically intercept the molten slag floating on the surface of the molten steel and cannot adaptively adjust according to instantaneous changes in the inflow rate and pressure. When the molten steel flow rate is low, in order to maintain the necessary slag-blocking effect, the bottom end of the slag removal rod has to extend further into the rectangular chute, which significantly reduces the effective flow cross-section. Once the flow rate increases, the slag removal rod at this fixed depth immediately becomes a strong throttling element. According to the principles of fluid mechanics, the sudden contraction of the flow channel cross-section will lead to a sharp increase in local velocity and a significant pressure loss, which in turn causes the liquid level to rise and violent turbulence to occur. During this process, air and oxide film are easily entrained into the molten steel, making... The filling stability is severely deteriorated. Even more disadvantageous is that the chute has a rectangular cross-section, and its right-angled edges form typical flow dead corners and geometric sharp corner areas. When molten steel flows through these areas, boundary layer separation and eddy current retention are likely to occur. The liquid metal retained in the dead corners cannot be effectively replaced for a long time, which not only aggravates the formation of oxide inclusions, but also greatly increases the risk of internal defects such as cold shuts and shrinkage porosity after solidification. It can be seen that the existing technology fully embodies the inherent contradiction between filtration effect and flow smoothness in traditional equipment with fixed baffle filter structure and rectangular flow channel design. This makes it extremely inconvenient to use and difficult to meet the stringent requirements of precision forming of high-purity and high-density steel plates. This embodiment is invented to solve the above problems.

[0020] Please see Figures 1 to 8 This invention provides a technical solution: a high-performance steel plate precision forming equipment, including a casting pipe 1, a driven plate 5 capable of moving left and right inside the casting pipe 1, and a casting concave plate 25 fixedly connected to the inner bottom surface of the casting pipe 1. The right-view cross-sectional shape of the casting concave plate 25 is precisely designed as a semi-circle. When liquid metal enters the casting pipe 1, it will naturally fall onto the inner circumferential surface of the casting concave plate 25 under the action of gravity. Thus, the semi-circular curved surface allows the fluid to spread smoothly along the wall, avoiding flow separation or local eddy stagnation areas. At the same time, because the casting concave plate 25 adopts this continuous curved surface configuration without sharp corners or steps, there are no structural dead corners on the entire inner circumferential surface, thereby effectively preventing the fluid from accumulating in the casting concave plate 25. 5. An internal accumulation, oxidation, or solidification cold shut is formed. A mounting plate 10 is provided directly below the driven plate 5, which can move and rotate synchronously with it. Multiple first blocking vertical plates 11 are fixedly connected to the lower surface of the mounting plate 10, with one end of each plate abutting against the inner wall of the casting concave plate 25. A second blocking vertical plate 12 is provided on the right side of each of the multiple first blocking vertical plates 11. The bottom end of the second blocking vertical plate 12 also abuts against the inner wall of the casting concave plate 25. The bottom ends of the first blocking vertical plates 11 and the second blocking vertical plates 12 are slidably connected to the casting concave plate 25. Multiple telescopic blocking components are passed through the front and rear ends of the right side of the multiple first blocking vertical plates 11, with one end of each plate fixedly connected to the corresponding second blocking vertical plate 12. An insulation layer 6 is filled between the inner side of the pouring pipe 1 and the pouring concave plate 25, and a number of stable support columns 7 with one end set on the pouring concave plate 25 are fixedly connected to the inner bottom surface of the pouring pipe 1. The insulation layer 6 can greatly reduce the heat loss from the pouring pipe 1 to the external environment. A support frame 2 is fixedly connected to the lower surface of the pouring pipe 1. Two chains that can rotate synchronously are installed inside the support frame 2, and a drive plate 4 is fixedly connected to the chains. Both ends of the drive plate 4 are fixedly connected to the active plate 3, and the top of the active plate 3 is fixedly connected to the driven plate 5. The chain drive mechanism configured in the support frame 2 is a mature technology in this field. It relies on the precise meshing of chain links and sprocket teeth to achieve power transmission. Its transmission mechanism will not be described in detail. During operation, the chain is driven to rotate on the support frame 2, thereby ensuring that the motion transmission has strict synchronization and positioning accuracy. As the chain runs, the drive plate 4 fixed on the chain is driven to move smoothly along the preset trajectory. During the movement, the drive plate 4 synchronously drags the active plates 3 at its front and rear ends. The active plates 3 then transmit the displacement upward, causing the driven plate 5 to move left and right accordingly. The top of both the front and rear sides of the pouring pipe 1 is provided with slide rails 18, and the front and rear ends of the driven plate 5 are connected through the corresponding slide rails 18, and the driven plate 5 and the slide rails 18 are slidably connected. A first support plate 8 and a second support plate 14 are fixedly connected to each other along the axial direction of the pouring pipe 1 on the inner top surface of the driven plate 5. A limiting support column 9 that can move synchronously with the first support plate 8 and the second support plate 14 is provided between them. A limiting ring plate 15 is fixedly connected to the middle of the limiting support column 9. The center of the upper surface of the mounting plate 10 is fixedly connected to the limiting ring plate 15. Therefore, when the driven plate 5 is displaced along the slide 18, it will simultaneously drive the first support plate 8 and the second support plate 14 to move synchronously through the rigid connection structure. Since the two ends of the limiting support column 9 are reliably clamped and limited by the first support plate 8 and the second support plate 14, the two will drag the limiting support column 9 to move synchronously when they move. Subsequently, the movement of the limiting support column 9 is transmitted downward through the limiting ring plate 15 fixed in the middle, driving the mounting plate 10 to follow the movement at the same speed and direction, thereby ensuring that the mounting plate 10 and the driven plate 5 always maintain a precise following relationship. Then, the mounting plate 10 drives the multiple first blocking vertical plates 11 fixed to its lower surface to move synchronously. The first blocking vertical plate 11 transmits the traction force to the corresponding second blocking vertical plate 12 through the telescopic blocking components penetrating its right front and rear ends, so that each second blocking vertical plate 12 can move synchronously together.

[0021] The telescopic blocking component includes a blocking barrel 13 with one end penetrating through the first blocking vertical plate 11. A blocking post 19 with one end fixedly connected to the corresponding second blocking vertical plate 12 is slidably connected inside the blocking barrel 13. A tension spring 20 with one end fixedly connected to the blocking post 19 is installed inside the blocking barrel 13. During the casting process, when the molten steel enters the casting concave plate 25 and spreads along its semi-circular inner wall, the liquid metal first passes through the flow channel between the first blocking vertical plate 11 and the second blocking vertical plate 12. At this time, multiple arrayed blocking columns 19 perform forced filtration of the flowing molten steel based on the principle of mechanical filtration, effectively trapping steel slag and non-metallic inclusions in the melt using the gaps between the columns, thus allowing the purified molten steel to continue flowing forward. According to the hydrodynamic effect, when the flow rate of the molten steel entering the casting pipe 1 increases, the flow velocity in the channel increases accordingly. The dynamic pressure acting on the front surface of the second blocking vertical plate 12 increases accordingly, pushing the second blocking vertical plate 12 to move away from the first blocking vertical plate 11. The second blocking vertical plate 12 drives the multiple blocking columns 19 fixed to it to slide synchronously in the corresponding blocking barrel 13. At the same time, the movement of the blocking columns 19 forces the tension spring 20 installed in the blocking barrel 13 to be gradually stretched. According to the basic characteristic that the force and deformation of the elastic element are positively correlated, the amount of stretching deformation of the tension spring 20 increases with the increase of the fluid dynamic pressure, thereby realizing the adaptive adjustment of the baffle opening. In this way, the cross-sectional area of ​​the flow between the first blocking vertical plate 11 and the second blocking vertical plate 12 increases, which meets the need to reduce flow resistance under high flow conditions, ensures the smooth flow of molten steel, and avoids the liquid level from rising or turbulent air entrapment caused by excessive throttling. However, no matter how the opening changes, the multiple blocking columns 19 in the telescopic blocking component always maintain the function of intercepting slag. The filter gap between the columns is still smaller than the critical passage size of the slag. Therefore, the slag will still be reliably intercepted on the upstream side of the blocking column 19 and will not enter the subsequent steps with the molten steel.

[0022] Example 2 In the above embodiments, although by setting a second blocking vertical plate 12 that can move left and right, and by utilizing the mechanism that the distance between it and the first blocking vertical plate 11 can be adaptively adjusted according to the steel flow rate, it is possible to effectively intercept steel slag while meeting the need for smooth flow under different flow conditions, thus solving the core contradiction that the traditional fixed-opening slag-removing rod cannot simultaneously achieve the filtration effect and flow stability, in the actual continuous casting process, the steel flowing through the casting concave plate 25 will still inevitably leave discrete high-temperature viscous droplets on its semi-circular inner circumferential surface. Because the casting concave plate 25 is always in a high-temperature condition during continuous casting operations, and its own temperature is maintained above the solidification point of the molten steel, these residual droplets do not solidify rapidly and instantly solidify into a hard shell. Instead, under the combined effect of surface tension and interfacial adhesion, they adhere to the inner circumferential surface of the semicircle in a viscous liquid or semi-molten state. If they are not cleaned in time, as the number of continuous casting cycles increases, new droplets will continue to accumulate and thicken with the existing viscous droplets as the core when the molten steel is repeatedly covered. When exposed to air for a long time, they will gradually oxidize and form a rough oxide layer. This will not only change the original geometric contour of the semicircular surface and destroy its smooth flow characteristics, but also cause flow separation and eddy current retention zones when the molten steel flows through again due to the increased wall roughness. This embodiment is invented to solve the above problems.

[0023] Please see Figures 1 to 8 Based on the above embodiments, the technical solution adopted includes a limiting support column 9 having one end rotatably and slidably inserted into the second support plate 14, the limiting support column 9 having one end rotatably and slidably inserted into the first support plate 8, and a spring 16 being provided between the limiting ring plate 15 and the first support plate 8, and the spring 16 being sleeved on the limiting support column 9 without contact. A driven ring plate 17 is rotatably connected to the side of the first support plate 8 near the second support plate 14. The end of the limiting support column 9 away from the second support plate 14 passes through the driven ring plate 17, and the limiting support column 9 can rotate and slide on the driven ring plate 17. The two ends of the spring 16 are fixedly connected to the limiting ring plate 15 and the driven ring plate 17 respectively. A spiral groove is opened at the end of the limiting support column 9 inserted into the first support plate 8, and a limiting slider with one end slidably connected in the spiral groove is fixedly connected to the inner wall of the first support plate 8. Therefore, when the limiting ring plate 15 is subjected to an external driving force and produces an axial displacement toward the first support plate 8, the limiting ring plate 15 will drive the limiting support column 9 fixedly connected to it to move axially synchronously. Since the end of the limiting support column 9 inserted into the first support plate 8 has a spiral groove, and the inner wall of the first support plate 8 is fixedly connected to a limiting slider with one end slidably connected in the spiral groove, according to the basic principle of the spiral transmission mechanism to convert linear motion into rotational motion, while the limiting support column 9 is axially translated, the spiral groove is guided and constrained by the limiting slider, forcing the limiting support column 9 to rotate synchronously around its own axis, thereby realizing the composite motion of translation and rotation. The rotational motion of the limiting support column 9 is further transmitted to the limiting ring plate 15 fixed in its middle, so that the limiting ring plate 15 and the mounting plate 10 connected to it rotate together. At the same time, one end of the spring 16 rotates synchronously with the limiting ring plate 15, while the other end rotates freely through the rotating pair formed between the driven ring plate 17 and the first support plate 8. The driven ring plate 17 absorbs the torsional angular displacement of the spring 16, thereby ensuring that the spring 16 will not generate additional torsional deformation stress due to inconsistent torsional constraints at both ends while it is normally compressed and storing energy, thus ensuring the reliability and service life of the elastic element.

[0024] The inner circumferential surface of the blocking barrel 13 is provided with a groove 22, wherein the groove 22 is annular in shape and the diameter of the groove 22 is larger than the diameter of the inner circumferential surface of the blocking barrel 13. A slider 21 is slidably connected in the groove 22, so the slider 21 can only slide in the groove 22. The end of the tension spring 20 away from the blocking post 19 is fixedly connected to the slider 21. The front and rear ends of the first blocking vertical plate 11 near the second blocking vertical plate 12 are provided with hidden grooves 23. The bottom right side of the first blocking vertical plate 11 and the second blocking vertical plate 12 are both fixedly connected with arc-shaped toothed plates 24. During the filtration process, when the flow rate of molten steel increases and pushes the blocking column 19 to move away from the blocking barrel 13, the blocking column 19 will stretch the tension spring 20, and at the same time the slider 21 has slid along the slide groove 22 to the right limit position. In the initial assembly state, even if the tension spring 20 is not stretched, a pre-set gap is maintained between the first blocking vertical plate 11 and the second blocking vertical plate 12 to meet the basic flow and slag interception requirements. When it is necessary to clean the high-temperature viscous droplets remaining on the inner circumferential surface of the casting concave plate 25, the driven plate 5 drives the mounting plate 10 to move to the right. Since the bottom end of the second blocking vertical plate 12 is always in close contact with the inner wall of the casting concave plate 25, under the combined action of contact pressure and high-temperature adhesion effect, sufficient static friction is generated between the two interfaces, so that the second blocking vertical plate 12 is temporarily kept in a limited position relative to the casting concave plate 25. As the first blocking vertical plate 11 continues to move to the right, the blocking barrel 13 and the blocking column 19 slide relative to each other, and the slider 21 also slides accordingly in the groove 22 until the front and rear ends of the second blocking vertical plate 12 are completely inserted into the corresponding hidden groove 23. At this time, the first blocking vertical plate 11 and the second blocking vertical plate 12 achieve structural interlocking. The first blocking vertical plate 11 begins to push the second blocking vertical plate 12 to move to the right synchronously. In this state, multiple first blocking vertical plates 11 and second blocking vertical plates 12 are combined to form a complete semi-circular scraper, and each arc-shaped toothed plate 24 is also spliced ​​together to form a continuous arc-shaped sawtooth structure. When the semi-circular scraper moves along the inner wall of the casting concave plate 25, it can effectively mechanically scrape off the attached droplets. If it encounters abnormally tightly adhered droplets or a semi-oxide layer, the scraper's movement is obstructed. The resulting axial reaction force is transmitted to the limiting support column 9 through the mounting plate 10 and the limiting ring plate 15, forcing the limiting support column 9 to move axially into the first support plate 8. Through the helical transmission cooperation between its helical groove at one end and the limiting slider, the axial linear motion is converted into rotational motion, thus superimposing circumferential rotation on the semi-circular scraper while it is translating. This axial scraping force and... The composite force field formed by the circumferential torsional shear force can generate a peeling and shearing synergistic effect at the adhesion interface, effectively reducing the removal resistance and significantly improving the droplet scraping efficiency. At the same time, it avoids the scratches caused to the inner wall of the casting concave plate 25 by a single axial strong scraping. If the casting concave plate 25 is scraped by pure axial thrust, scratches and micro-damage are easily generated on the semi-circular inner circumferential surface of the casting concave plate 25, destroying its smooth flow guiding surface. This leads to boundary layer separation and eddy current retention during subsequent steel flow, which in turn aggravates new droplet residues and oxide inclusions, seriously affecting the forming quality and surface finish of the steel plate. Furthermore, after multiple arc-shaped toothed plates 24 are spliced ​​together to form a continuous arc-shaped sawtooth structure, as they rotate synchronously with the semi-circular scraper, the wedge-shaped tips of the sawtooth can embed into the interface between the viscous droplet and the inner circumferential surface of the casting concave plate 25. Under the combined action of circumferential shear force and axial thrust, local stress concentration is generated, which effectively peels the droplet off from the adhesion surface, rather than simply relying on thrust to remove it. This ensures cleaning efficiency while protecting the surface integrity of the semi-circular inner wall of the casting concave plate 25. Meanwhile, when it is necessary to clean the steel slag and non-metallic inclusions that have been intercepted and accumulated in the pouring pipe 1 by multiple blocking columns 19, the operator can control the drive plate 4 to move to the left through the external controller, so that the driven plate 5 moves away from the impurity accumulation area. Then, the baffle on the left side of the pouring pipe 1 can be opened to smoothly discharge the intercepted impurities. Similarly, when it is necessary to clean the oxide scale and solidified liquid droplet residue scraped and collected from the inner circumference of the pouring concave plate 25 by the semi-circular scraper, the operator can open the cover plate at the right end of the upper surface of the pouring pipe 1 to facilitate the removal of such impurities from the pouring pipe 1, thereby keeping the inside of the flow channel clean and ensuring the stability of the subsequent pouring process and the quality of steel plate forming.

[0025] Please see Figure 1 This invention provides a technical solution: an intelligent full-process processing technology completed by high-performance steel plate precision forming equipment, comprising the following steps: S1. Steel smelting and transfer: Steel billets are added to the steel smelting furnace to produce molten steel at 1450-1700℃, and the molten steel is transferred to the casting ladle through the intermediate ladle; S2. Preheating treatment of ceramic particles: Start the heating furnace to heat the ceramic particles to 500-1400℃; S3, Steel-Ceramic Mixed Casting and Distribution: Molten steel from the ladle and ceramic particles from the heating furnace are poured together into the homogenizer through the casting pipe 1. The ceramic particles are evenly dispersed on the upper layer of the molten steel in the homogenizer. S4. Horizontal continuous casting composite molding: Ceramic particles and molten steel flow from the guide channel of the uniform feeder into the feed chute of the horizontal continuous casting machine, and are continuously cast by the horizontal continuous casting machine to obtain metal-based composite ceramic steel plates.

[0026] The intelligent full-process processing technology completed by the high-performance steel plate precision forming device is the same as the production system and process of a metal-based composite ceramic steel plate disclosed in the patent application number 202110180972.3. Therefore, its specific process steps and parameters will not be repeated here.

[0027] In summary, when this high-performance steel plate precision forming equipment and its intelligent full-process processing technology are used, the semi-circular continuous curved surface configuration of the casting concave plate 25 is first used to eliminate the structural dead corners and geometric sharp corners of the traditional rectangular flow channel, guiding the molten steel to spread smoothly along the wall surface, effectively suppressing flow separation, eddy retention and air entrapment. During the casting process, the liquid metal passes through the flow channel between the first blocking vertical plate 11 and the second blocking vertical plate 12. The arrayed blocking columns 19 forcibly intercept steel slag and non-metallic inclusions based on the mechanical filtration principle. At the same time, according to the changes in the flow rate and velocity of the molten steel, the second blocking vertical plate 12 is driven by the hydrodynamic pressure effect to move the blocking columns 19 within the blocking barrel 13 and stretch the tension spring 20, thereby achieving adaptive adjustment of the baffle opening, thus taking into account both interception efficiency and filling stability. When it is necessary to clean the high-temperature viscous liquid droplets remaining on the semi-circular inner circumferential surface of the casting concave plate 25, the driven plate 5 drives the mounting plate 10 to move to the right under the chain drive of the support frame 2. The second blocking vertical plate 12 is temporarily limited under the action of static friction at the bottom end and high-temperature adhesion effect until its front and rear end faces are completely inserted into the corresponding hidden groove 23, and interlocked with the first blocking vertical plate 11 to form a complete semi-circular scraper. Each arc-shaped toothed plate 24 is synchronously spliced ​​into a continuous arc-shaped sawtooth structure. The semi-circular scraper moves along the inner wall of the casting concave plate 25 and embeds itself into the droplet interface with the help of the sawtooth wedge-shaped tooth tip. When it encounters a tightly adhered droplet or semi-oxide skin, the axial reaction force generated by the scraper being obstructed is transmitted to the limiting support column 9 through the mounting plate 10 and the limiting ring plate 15, causing it to move axially and be converted into circumferential rotation through the cooperation of the limiting slider in the first support plate 8 with the spiral groove. This gives the scraper a composite force field of axial pushing and circumferential shearing, thereby efficiently peeling off the droplets and avoiding scratching the smooth curved surface of the casting concave plate 25. Impurities such as steel slag that are filtered and intercepted can be discharged by controlling the drive plate 4 to move to the left and opening the left side baffle of the pouring pipe 1 through the external controller. The scraped oxide scale and residue can be cleaned by opening the right end cover plate on the upper surface of the pouring pipe 1 to keep the inside of the flow channel clean.
