Description

Technical Field

[0001] This utility model relates to the field of steel ingot cooling technology in the metallurgical industry, and in particular to a uniform heat dissipation device for steel ingots. Background Technology

[0002] As a crucial intermediate product in the metallurgical industry, the cooling process of steel ingots has a decisive impact on the quality of the final product. Traditional steel ingot cooling processes suffer from numerous technical bottlenecks: while natural air cooling is simple to operate, its cooling efficiency is low and uniformity is difficult to guarantee, leading to coarsening of the grain structure within the ingot due to uneven cooling; forced air cooling devices, although increasing the cooling rate, result in a significant temperature gradient on the ingot surface due to uneven airflow distribution, easily causing stress concentration problems in subsequent processing. Especially for large-section steel ingots, the heat in the core is difficult to effectively dissipate, often resulting in a "cold outside, hot inside" condition, severely affecting the consistency of material properties.

[0003] Existing heat dissipation devices also have significant structural design flaws: fixed heat dissipation devices cannot adapt to the needs of steel ingots of different specifications, resulting in low equipment utilization; while modular heat dissipation structures generally suffer from insufficient connection stability, easily leading to structural loosening under thermal cycling conditions and affecting the sustainability of heat dissipation. More importantly, existing devices struggle to achieve uniform heat dissipation from multiple angles and in all directions, and the arrangement of heat dissipation holes lacks scientific design, failing to form effective heat convection channels. These problems severely restrict the production efficiency and quality control of high-quality steel ingots. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a uniform heat dissipation device for steel ingots that can achieve uniform heat dissipation, improve heat dissipation uniformity, and adapt to the needs of steel ingots of different specifications.

[0005] This utility model is implemented using the following method: a uniform heat dissipation device for steel ingots, including a first arc-shaped plate and a second arc-shaped plate. Multiple first heat dissipation holes are equally spaced on the first arc-shaped plate and the second arc-shaped plate. Arc-shaped connecting plates are provided on the upper and lower surfaces of the first arc-shaped plate and the second arc-shaped plate. Extension blocks extend downward from the front and rear surfaces of the upper arc-shaped connecting plate. The extension blocks at the left and right ends are connected by connecting bolts. Limiting slots are provided at the front and rear ends of the upper surface of the upper arc-shaped connecting plate. Engaging protrusions corresponding to the limiting slots are provided at the front and rear ends of the lower surface of the lower arc-shaped connecting plate.

[0006] Furthermore, the first arc-shaped plate and the second arc-shaped plate are connected to form a heat dissipation cylinder.

[0007] Furthermore, the limiting slot and engaging protrusion enable the connection and stacking of two heat dissipation cylinders to achieve the nesting of steel ingots.

[0008] Furthermore, the upper left and right ends of the heat dissipation cylinder are connected to arc-shaped cover plates, and the arc-shaped cover plates are provided with second heat dissipation holes at equal intervals. The lower surface of the arc-shaped cover plates is provided with connecting protrusions at both the front and rear ends, which correspond to the limiting slots.

[0009] The beneficial effects of this utility model are as follows: This utility model, by setting an arc-shaped plate combination structure with heat dissipation holes and a modular connection mechanism, utilizes the cooperation of the limiting slot and the engaging protrusion to achieve multi-level stacking, which solves the problems of uneven heat dissipation and poor structural stability of traditional devices, and has the advantages of improving heat dissipation efficiency, ensuring cooling uniformity and enhancing equipment adaptability. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model.

[0011] Figure 2 This is a schematic diagram of the usage state of this utility model. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] Please see Figure 1 and Figure 2 As shown, this utility model provides an embodiment: a uniform heat dissipation device for steel ingots, including a first arc plate 1 and a second arc plate 2. The first arc plate 1 and the second arc plate 2 are provided with a plurality of first heat dissipation holes 3 at equal intervals. The upper and lower surfaces of the first arc plate 1 and the second arc plate 2 are provided with arc connecting plates 4. The front and rear surfaces of the upper arc connecting plate 4 are provided with extension blocks 41 extending downward. The extension blocks 41 at the left and right ends are connected by connecting bolts. The front and rear ends of the upper surface of the upper arc connecting plate 4 are provided with limiting slots 42. The front and rear ends of the lower surface of the lower arc connecting plate 4 are provided with engaging protrusions 43 corresponding to the limiting slots 42.

[0014] Among them, the first arc plate and the second arc plate refer to metal plates with specific curvatures, which can be made of high-temperature resistant alloy materials, and their curvature can match the outer surface of the steel ingot.

[0015] The first heat dissipation hole refers to a hole that is evenly distributed along the length of the arc plate. Specifically, it can be a circular or elliptical through hole to promote air circulation.

[0016] Among them, the arc-shaped connecting plate refers to the strip-shaped structure fixed to the upper and lower edges of the arc plate. It can be fixed by welding or bolts to provide a connecting support surface.

[0017] The extension block refers to the protrusion extending downward from the upper arc-shaped connecting plate. Specifically, it can be a metal block integrally formed with the connecting plate, used to bear the tightening force of the connecting bolts.

[0018] The limiting groove refers to the groove opened on the surface of the upper arc-shaped connecting plate. Specifically, it can be rectangular or trapezoidal in cross-section and is used to engage and position with the engaging protrusion of the adjacent heat sink.

[0019] Specifically, the first and second arc-shaped plates are combined via an arc-shaped connecting plate to form an annular heat dissipation cylinder, which wraps around the outer surface of the steel ingot. Extension blocks and connecting bolts engage to achieve lateral fastening between adjacent heat dissipation cylinders, while limiting slots and engaging protrusions provide positioning constraints when stacked longitudinally. Heat dissipation holes create multi-directional airflow channels, allowing for continuous heat exchange with the outside air. Multiple heat dissipation cylinders are stacked and combined using connecting bolts and limiting structures, allowing for flexible adjustment of the number of wrapping layers to accommodate steel ingots of different sizes.

[0020] Compared to existing technologies, natural air cooling relies on passive heat dissipation, resulting in low efficiency. This device, however, uses a ring-shaped heat dissipation cylinder to create a wraparound heat dissipation path, achieving uniform cooling in a circular manner. Compared to the unidirectional airflow of forced air cooling devices, multiple rows of heat dissipation holes promote multidirectional airflow across the steel ingot surface. Existing modular structures are prone to creating heat dissipation dead zones due to unstable connections. This solution ensures a tight fit between modules through the rigid connection of extension blocks and bolts, as well as the interlocking design of limiting slots.

[0021] Through the above technical solutions, this application achieves a uniform distribution of heat dissipation paths on the surface of the steel ingot, reducing thermal stress caused by local temperature differences. The modular structure allows for adjustment of the number of combined layers according to the size of the steel ingot, avoiding the problem of limited specifications in traditional devices. The cooperation between the limiting slot and the engaging protrusion prevents misalignment during stacking, ensuring continuous heat dissipation between the heat dissipation cylinders. The extension block and bolt connection structure enhance overall stability and prevent loosening of connections due to vibration during long-term use.

[0022] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the first arc-shaped plate 1 and the second arc-shaped plate 2 are connected to form a heat dissipation cylinder.

[0023] The first and second arc-shaped plates refer to metal sheets with curved curvatures, specifically aluminum alloy or copper alloy sheets with high thermal conductivity. The curvatures of these plates create a fitting wrapping surface to the outer contour of the steel ingot. The heat dissipation cylinder is a cylindrical or elliptical hollow structure formed by the closure of two arc-shaped plates. It can be connected by bolts or welding, and its inner diameter can be adapted to the outer diameter of steel ingots of different specifications, forming a surrounding heat dissipation space.

[0024] Specifically, the first and second arc-shaped plates are assembled in a closed manner through a connecting structure at their edges, forming an annular heat dissipation channel inside the closed heat dissipation cylinder that is in close contact with the outer surface of the steel ingot. When the steel ingot is encased inside the heat dissipation cylinder, its surface heat diffuses outward through the thermal conduction of the arc-shaped plates. Simultaneously, the airflow channel formed by the first heat dissipation hole causes air convection inside the cylinder, accelerating the transfer of heat from the surface of the steel ingot to the external environment. The closed structure of the heat dissipation cylinder avoids the problem of gaps between the contact surface of traditional flat plate heat dissipation devices and the steel ingot, ensuring the continuity of the heat transfer path.

[0025] Compared to existing technologies, current forced air cooling devices use a single-sided blowing method, resulting in uneven heat dissipation of the steel ingot. This solution, however, achieves circumferential full-coverage heat dissipation of the steel ingot through a closed heat dissipation cylinder structure. Traditional modular heat dissipation structures create heat dissipation dead zones due to air leakage at the joints, while the closed cylinder structure of this solution eliminates airflow escape at the joints, ensuring consistent heat dissipation efficiency across all areas of the steel ingot surface.

[0026] Through the above technical solution, this application solves the problem of uneven circumferential heat dissipation in columnar steel ingots, significantly reducing the surface temperature gradient and avoiding structural stress caused by local overheating or undercooling. The closed structure of the heat dissipation cylinder can adapt to steel ingots of different diameters; universal installation can be achieved simply by adjusting the curvature of the arc plate, reducing the variety of tooling required in the factory. When the steel ingot is enclosed inside the heat dissipation cylinder, its surface airflow path is constrained to flow axially along the cylinder, forming a stable directional heat dissipation environment.

[0027] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the limiting slot 42 and the engaging protrusion 43 can realize the connection and stacking of two heat dissipation cylinders to achieve the nesting of steel ingots.

[0028] The limiting slot refers to a recessed structure on the surface of the arc-shaped connecting plate, which can be implemented using a rectangular or dovetail-shaped groove, used to mechanically engage with the protrusions of adjacent heat sinks. The engaging protrusion refers to a raised structure on the surface of the arc-shaped connecting plate, which can be implemented using a metal block matching the shape of the limiting slot, achieving axial positioning of the heat sink by embedding it into the slot. The engagement of these two components restricts the lateral displacement of the heat sinks in a stacked state while maintaining the continuity of the longitudinal heat dissipation channels.

[0029] Specifically, when two heat sinks need to be stacked, the limiting groove at the upper end of the lower heat sink and the engaging protrusion at the lower end of the upper heat sink engage with each other to form a stable vertical stacking structure. Multiple heat sinks can extend along the axial direction of the steel ingot through this connection method, forming a fitting space that matches the outer contour of the steel ingot. After stacking, the heat dissipation holes form a continuous heat dissipation path, and heat is evenly discharged through the gaps between adjacent heat sinks and the through holes.

[0030] Compared to existing technologies, current modular heat dissipation devices only use bolts or clips for planar connections, which cannot achieve multi-level vertical stacking, resulting in a discontinuous axial heat dissipation path for the steel ingots. This solution, through the three-dimensional cooperation of limiting slots and engaging protrusions, ensures that the heat dissipation cylinders maintain axial alignment and can adapt to the stacking requirements of steel ingots of different diameters, avoiding heat dissipation blind spots caused by misalignment of module connections.

[0031] Through the above technical solution, this application solves the positioning deviation problem when multi-stage heat dissipation cylinders are stacked vertically, ensuring that the heat dissipation holes form a continuous and unobstructed airflow channel in the axial direction, so that all areas of the steel ingot surface obtain uniform heat dissipation conditions. At the same time, this connection structure can flexibly adjust the number of stacking layers according to the length of the steel ingot, so as to adapt to steel ingots of different specifications.

[0032] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the upper left and right ends of the heat dissipation cylinder are connected to arc-shaped cover plates 5. The arc-shaped cover plates 5 are provided with second heat dissipation holes 51 at equal intervals. The lower surface of the arc-shaped cover plates 5 is provided with connecting protrusions 52 corresponding to the limiting slots 42 at both the front and rear ends.

[0033] The arc-shaped cover plate refers to the arc-shaped plate-like structure covering the opening at the top of the heat sink cylinder. It can be made by stamping metal sheets, and its curvature matches the arc shape of the heat sink cylinder to form a closed structure. The second heat dissipation hole refers to the through holes evenly distributed along the length of the arc-shaped cover plate. These holes can be circular or elliptical in shape and are used to promote airflow and enhance heat dissipation efficiency. The connecting protrusion refers to the raised structure on the lower surface of the arc-shaped cover plate. It can be made by welding or integral molding, and its shape complements the limiting groove to achieve a positioning connection.

[0034] Specifically, when the upper end of the heat sink needs to be sealed, the arc-shaped cover plate is inserted into the limiting groove of the lower heat sink through the connecting protrusion, so that the two arc-shaped cover plates form a continuous cover on the top of the heat sink. The second heat dissipation hole and the first heat dissipation hole together form a multi-directional heat dissipation channel, and the airflow can flow simultaneously along the axial and radial directions of the heat sink. The cooperation between the connecting protrusion and the limiting groove can limit the horizontal displacement of the arc-shaped cover plate, while allowing multiple heat sinks to be stacked vertically.

[0035] Compared to existing technologies, current modular heat dissipation structures lack a dedicated cover in the top area, obstructing the heat dissipation path at the top of the steel ingot. This solution, however, uses an arc-shaped cover to create a complete heat dissipation surface, preventing heat dissipation blind spots in the top area. In existing technologies, module connections rely solely on bolts, which are prone to thermal deformation and seal failure under high temperatures. The embedded fit between the connecting protrusion and the limiting slot compensates for dimensional changes caused by thermal expansion, maintaining connection stability.

[0036] Through the above technical solution, this application solves the problem of low heat dissipation efficiency in the top area of ​​the steel ingot and realizes a multi-dimensional heat dissipation path in both the axial and radial directions of the heat dissipation cylinder. The cooperation between the connecting protrusion and the limiting slot effectively prevents module misalignment during stacking and ensures the alignment of the axes of the multi-layer heat dissipation cylinder. The closed structure of the arc-shaped cover plate can block external impurities from entering the heat dissipation channel, while avoiding uneven heat loss caused by direct exposure of the high-temperature steel ingot.

[0037] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
