Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal smelting and rolling equipment, specifically to an anti-deformation iron plate structure suitable for the smelting and rolling process of ferrous metals, and is particularly suitable for iron plate components used for support, heat insulation, heat conduction or load bearing in high temperature and high load environments. Background Technology
[0002] In the smelting and rolling processes of ferrous metals (such as steel and cast iron), iron plate structures serve as important auxiliary components for purposes such as transmission, load bearing, heat insulation, and padding. They typically operate for extended periods in harsh environments involving high temperatures, heavy loads, and high-frequency impacts. To improve process stability and equipment safety, traditional production lines commonly incorporate metal iron plates in high-temperature zones to support or support hot metal products.
[0003] In existing technologies, the following methods are commonly used to improve the deformation resistance of iron plates: First, the iron plate body is thickened to increase rigidity, but this will lead to a significant increase in weight, which is not conducive to equipment load control and energy consumption optimization; Second, traditional straight reinforcing ribs are set, but under actual high-temperature operating conditions, the ribs are prone to warping, weld breakage, or uneven thermal expansion, resulting in overall instability of the iron plate; Third, a composite material coating is added to the surface of the iron plate to improve its thermal shock resistance, but this method has the problems of high cost, complex process, and easy coating peeling or failure in high-temperature environments.
[0004] Especially in continuous rolling production lines, the large temperature difference between the heated and cooled surfaces of the iron plate leads to a severe thermal stress gradient, which easily causes in-plane or localized stress concentration, resulting in phenomena such as bulging, warping, and fatigue cracks in the iron plate. These deformations not only affect product quality but may also cause malfunctions in upstream and downstream equipment, production interruptions, and in severe cases, even threaten operational safety.
[0005] In addition, since traditional iron plates mostly adopt simple flat plate structures or straight groove arrangements, they cannot effectively guide and absorb the multi-directional expansion stress caused by complex heat flow. Therefore, their fatigue resistance, service life and deformation suppression effect are significantly insufficient.
[0006] In summary, existing anti-deformation steel plate structures still have room for improvement in terms of thermal stress release resistance, bulging and warping prevention, structural stability, and material adaptability. There is an urgent need for an anti-deformation steel plate solution that is structurally sound, has strong thermal stress resistance, is simple to manufacture, and is highly adaptable to meet the safety and stability requirements of ferrous metal smelting and rolling processes. Summary of the Invention
[0007] To overcome the problems of thermal deformation and structural instability that easily occur in existing iron plate structures during high-temperature smelting and rolling, this utility model proposes a structurally sound, easy-to-manufacture, and highly adaptable anti-deformation iron plate structure. The following detailed description of the technical features of this utility model, combined with several possible implementation methods, aims to clearly demonstrate its technical advantages in mitigating thermal stress, improving structural rigidity, and adapting to complex working conditions.
[0008] In one embodiment of the present invention, a deformation-resistant iron plate structure for ferrous metal smelting and rolling is provided, comprising an iron plate body, wherein the iron plate body is a rectangular or approximately rectangular metal plate with a thickness of 8mm to 20mm; a plurality of Ω-shaped or wavy buffer grooves are provided on the heated surface of the iron plate body, the buffer grooves are evenly arranged along one direction or cross directions on the surface of the iron plate body, the groove width is 5 to 10mm, the depth is 1 to 3mm, and the groove spacing is 20 to 50mm; a plurality of reinforcing rib structures are provided on the back side of the iron plate body, the reinforcing rib structures are arranged in a cross shape, a star shape, or diagonally, and are fixedly connected to the iron plate body by spot welding, the reinforcing rib structures are made of rectangular flat steel with a cross section of 10mm × 20mm.
[0009] Furthermore, the buffer groove is a continuous wavy groove arranged laterally along the surface of the iron plate body to optimize the release path of thermal expansion stress.
[0010] Preferably, the iron plate body is made of medium carbon steel or chromium-molybdenum alloy steel to improve the mechanical strength and heat resistance of the iron plate in high-temperature environments.
[0011] Furthermore, the heated surface of the iron plate body is coated with a high-temperature resistant ceramic coating to enhance the iron plate's resistance to heat radiation and surface oxidation.
[0012] Alternatively, the buffer groove can be formed by mechanical milling, stamping or laser etching to meet the production needs of different manufacturing processes.
[0013] Furthermore, the anti-deformation iron plate structure is suitable for use as a base for rolling equipment, a heat transfer guide plate, or a smelting support plate.
[0014] Optionally, limiting holes are provided at the intersection of the reinforcing ribs to reduce structural deformation caused by thermal stress during welding.
[0015] Preferably, the angle between the reinforcing rib and the edge of the iron plate is 30 to 60 degrees to achieve a more reasonable thermal stress transmission path.
[0016] Furthermore, the thickness of the ceramic coating is 0.2 to 0.5 mm, and the coating material is alumina or zirconia ceramic, in order to balance heat reflectivity and adhesion.
[0017] Optionally, the four edges of the iron plate body are provided with a bending structure or a chamfer structure to alleviate the problem of thermal stress concentration at the corners.
[0018] Based on the above technical solution, the anti-deformation iron plate structure for ferrous metal smelting and rolling products of this utility model effectively disperses and buffers the thermal expansion and contraction stress caused by the temperature difference by setting Ω-shaped or wave-shaped buffer grooves on the heated surface of the iron plate body and setting cross-shaped, star-shaped or obliquely arranged reinforcing ribs on the back side, thereby significantly reducing the risk of deformation such as bulging, warping and fatigue cracking of traditional iron plates during heating.
[0019] Specifically, the non-linear design of the buffer groove (such as Ω-shaped or wavy) breaks the thermal stress concentration path that is easily caused by traditional straight ribs, allowing heat to diffuse in a non-linear direction, which helps to achieve stress redistribution and mitigate local expansion. Combined with the multi-directional reinforcing ribs arranged on the back, it not only improves the load-bearing rigidity, but also allows the structure to undergo slight elastic deformation with temperature difference rather than rigid fracture, which greatly extends the fatigue life of the iron plate.
[0020] Furthermore, by using medium carbon steel or chromium-molybdenum alloy steel, oxidation resistance and heat deformation resistance can be further improved while ensuring sufficient structural strength, making it particularly suitable for the high-temperature thermal shock environment in ferrous metal smelting. High-temperature resistant ceramic coatings such as alumina or zirconium oxide applied to the surface not only increase the reflectivity of heat radiation but also slow down the rate of temperature rise on the iron plate surface, delaying the formation of hot cracks.
[0021] In terms of manufacturing process, the buffer groove can be processed by conventional laser etching, stamping, milling and other methods. The structure is simple and clear and suitable for CNC mass production. The spot welding connection of the reinforcing ribs greatly reduces the residual stress in the welding area, and the limiting holes can be set at the key intersections to reduce the risk of thermal deformation.
[0022] This utility model's structure has excellent adaptability and expandability, and can be widely applied to various types of equipment such as rolling mill bases, metallurgical heating platforms, heat treatment trays, and cooling bed insulation panels. For different application scenarios, the arrangement density of the buffer grooves, the angle of the reinforcing ribs, the material selection, and the surface treatment method can be flexibly adjusted to form a series of modular product solutions, improving the standardization level and maintenance efficiency of metallurgical equipment manufacturing.
[0023] Therefore, this utility model not only effectively solves the problem of easy deformation and fatigue damage of existing iron plate structures under high temperature and heavy load environment, but also has the advantages of simple process implementation, reasonable cost control and wide applicability, and has significant industrial application prospects and promotion value.

[0029] To make the technical solution, structural features and beneficial effects of this utility model clearer, the following describes the specific structure, functional implementation and applicable scenarios of this utility model in further detail with reference to the accompanying drawings and specific embodiments.
[0030] It should be understood that the following embodiments are only used to illustrate the basic principles of this utility model and do not constitute a limitation on the scope of protection of this utility model. Unless otherwise specified, various structural modifications, combination optimizations, or material substitutions made by those skilled in the art based on the prior art should fall within the scope of protection of this utility model.
[0031] Please see Figure 1 This utility model discloses a deformation-resistant iron plate structure for ferrous metal smelting and rolling, which includes an iron plate body 1, a plurality of buffer grooves 2 disposed on the heated surface of the iron plate body 1, and reinforcing ribs 3 arranged on the back side of the iron plate body 1.
[0032] The iron plate body 1 is preferably a rectangular or nearly rectangular metal plate with a thickness ranging from 8mm to 20mm. It is used to support high-temperature rolled workpieces or to provide heat insulation and support. Its heated surface faces the smelting or rolling heat source and is the main surface for heat radiation and heat conduction, which easily generates thermal expansion and contraction stress.
[0033] To alleviate in-plane stress concentration caused by high temperature, multiple Ω-shaped or wavy buffer grooves 2 are provided on the heated surface of the iron plate body 1. The buffer grooves 2 are arranged at equal intervals along the length direction, width direction, or the intersection of both of the iron plate, forming a multi-directional flexible stress release structure, which helps to guide stress diffusion when the iron plate expands due to heat and prevents bulging or warping deformation.
[0034] Multiple reinforcing ribs 3 are welded to the back of the iron plate body 1. The reinforcing ribs 3 are arranged in a cross shape, a star shape, or diagonally, and are fixedly connected to the iron plate body 1 by spot welding to enhance the overall structural rigidity and support stability. The reinforcing ribs 3 and the buffer groove 2 cooperate to form a two-way adjustment mechanism between the surface and the back, which releases thermal stress on the one hand and supports structural deformation on the other.
[0035] The above structure can be widely used in hot bearing platforms of smelting equipment, intermediate conveying structures of rolling production lines, or high-temperature support base plates, and has the advantages of strong thermal shock resistance, long fatigue life, and high structural stability.
[0036] Example 1: Detailed Explanation of Buffer Tank Structure
[0037] Please see Figure 2 In this embodiment of the utility model, the buffer groove 2 is provided on the heated surface of the iron plate body 1 to alleviate the in-plane stress concentration caused by thermal expansion and contraction at high temperature, and to prevent the iron plate from bulging, warping or cracking.
[0038] The cross-section of the buffer groove 2 is preferably Ω-shaped or wavy, and it is arranged at equal intervals along the surface of the iron plate. The arrangement direction can be the length direction, the width direction, or a cross arrangement at a certain angle to achieve multi-directional stress release function. Compared with the traditional straight groove, this non-linear structure groove has a higher flexible deformation capacity under heat, which can effectively guide and diffuse thermal expansion force, thereby decomposing local thermal stress.
[0039] Preferably, the structural parameters of the buffer groove 2 are as follows:
[0040] The groove depth is 1–3 mm;
[0041] The groove width is 5-10mm;
[0042] The groove spacing is 20-50mm.
[0043] The above parameters can be flexibly adjusted according to the heat flux density and heated area of the iron plate in the actual use scenario, so as to achieve a balance between thermal stress control and structural strength.
[0044] In terms of manufacturing process, the buffer groove 2 can be formed by various methods, including but not limited to mechanical milling, stamping, or laser etching. If laser etching technology is used, it can ensure processing accuracy while avoiding an excessively large heat-affected zone on the iron plate substrate, thus reducing the risk of residual thermal stress. If stamping is used, it is suitable for mass production and has high economic efficiency.
[0045] Furthermore, the buffer groove 2 can be designed as a continuous wavy groove, arranged horizontally along the iron plate, so that the stress diffusion path is more uniform and suitable for high-frequency thermal cycling environment.
[0046] By setting this type of buffer groove structure, this utility model effectively improves the adaptability of iron plate to thermal deformation, extends its service life, and ensures its stable operation in high-temperature smelting and rolling production without significantly increasing the material thickness or weight.
[0047] Example 2: Detailed Explanation of the Reinforcing Rib Structure
[0048] Please see Figure 3 In this embodiment of the utility model, in order to further improve the structural rigidity and fatigue resistance of the iron plate body 1 under high temperature and high load environment, a number of reinforcing ribs 3 are provided on its back side.
[0049] The reinforcing ribs 3 are preferably arranged in a cross shape, a star shape, or diagonally, which enhances the overall bending stiffness and compressive strength of the iron plate through multi-directional structural support. This staggered structural arrangement is superior to the traditional parallel rib arrangement and can effectively counteract the bulging or twisting of the plate surface caused by local thermal expansion.
[0050] Each reinforcing rib 3 is preferably made of rectangular flat steel with a cross-sectional dimension of 10mm×20mm. It has good linear stiffness and resistance to thermal fatigue, while controlling the increase in the overall weight of the iron plate, thus meeting the balance requirements of structural strength and lightweight.
[0051] The reinforcing rib 3 is fixedly connected to the back of the iron plate body 1 by spot welding. Compared with continuous welding, spot welding can reduce the welding heat input, reduce the thermal stress concentration in the weld area, and help improve the fatigue life of the welded joint. In addition, the spot welding layout can be optimized according to the arrangement density of the reinforcing ribs to improve welding efficiency.
[0052] Furthermore, a limiting hole is provided at the intersection of the reinforcing ribs 3. This limiting hole is used to release local thermal stress during welding, suppress plate warping, and play a role in thermal expansion buffering during use, thereby improving the thermal stability of the overall structure.
[0053] Preferably, the angle between the reinforcing rib and the edge of the iron plate is 30° to 60°. This angle arrangement helps to guide the thermal stress transmitted along the plate surface to the boundary area along the direction of the reinforcing rib, reducing the accumulation of thermal stress in the central area, thereby further improving the resistance to deformation.
[0054] The reinforcing rib 3 works in conjunction with the aforementioned buffer groove 2. The former provides overall support and structural stability, while the latter provides an in-plane thermal stress release channel, achieving a combined effect of "structural reinforcement + stress relief". This significantly improves the durability and shape retention of the iron plate during multiple thermal cycles, mechanical impacts, and long-term service.
[0055] Example 3: Materials and Coating Description
[0056] In this embodiment, to further improve the performance of the iron plate structure under high-temperature conditions in ferrous metal smelting and rolling, the iron plate body 1 is preferably made of medium carbon steel or chromium-molybdenum alloy steel.
[0057] Medium carbon steel possesses excellent comprehensive mechanical properties and high wear resistance, making it suitable for structural components subjected to repeated thermal shocks. Chromium-molybdenum alloy steel, on the other hand, exhibits superior oxidation resistance, thermal strength, and ductility at high temperatures, making it suitable for work platforms subjected to frequent thermal expansion and contraction cycles. Users can flexibly select materials based on their application scenarios (such as temperature range, stress level, and service life) to adapt to different working conditions.
[0058] To further improve the heat radiation resistance and surface durability of the heated surface, a high-temperature resistant ceramic coating can be optionally sprayed onto the heated surface of the iron plate body 1. The coating material is preferably alumina (Al2O3) or zirconium oxide (ZrO2) ceramic, both of which possess the following properties:
[0059] High melting point and excellent thermal stability;
[0060] It has low thermal conductivity and provides some insulation.
[0061] High hardness and good thermal shock resistance;
[0062] Good adhesion and anti-peeling properties.
[0063] Preferably, the thickness of the ceramic coating is 0.2 to 0.5 mm, which ensures the heat radiation resistance effect while avoiding excessive coverage of the overall structure and affecting the heat conduction efficiency.
[0064] Ceramic coatings can be formed through plasma spraying, flame spraying, or sol-gel methods. The spraying process requires pretreatment of the iron plate surface (such as sandblasting to roughen it) to improve adhesion, and the appropriate coating thickness and density should be selected based on the working conditions.
[0065] The selection of the above materials and the surface ceramic treatment scheme, combined with the buffer groove structure and the reinforcing rib structure, further enhance the service capability of this utility model under harsh conditions such as high temperature, high stress, and cyclic thermal load, effectively extend the service life of the iron plate, and reduce equipment maintenance costs and downtime risks.
[0066] Example 4: Edge Structure and Application Scenarios Expansion
[0067] In this embodiment, to further improve the stability and adaptability of the iron plate structure in practical applications, the four edges of the iron plate body 1 may be provided with a bending structure or a chamfer structure to optimize the stress distribution in the edge area and avoid edge cracks, peeling or deformation caused by thermal stress concentration or mechanical interference.
[0068] Specifically, the edge bending structure can adopt a downward or inward fixed-angle folding form to strengthen the edge rigidity and absorb some boundary stress during thermal expansion and contraction; the chamfering structure can reduce the risk of crack initiation by removing sharp corners and forming a transition area at a certain angle. This type of structure not only improves the overall fatigue resistance of the iron plate, but also facilitates fitting, positioning, or sliding connection with other equipment components.
[0069] Furthermore, the structure of this utility model has good versatility and expandability, and can be widely applied to various high-temperature and heavy-load scenarios, including but not limited to:
[0070] The base of the rolling equipment in a ferrous metal hot rolling production line;
[0071] High-temperature support plates or heat-insulating guide plates in smelting equipment;
[0072] Intermediate transfer receiving plate on continuous casting platform or cooling bed;
[0073] High-temperature zone workpiece turnover trays or heat treatment fixture base plates, etc.
[0074] Depending on the usage environment and process requirements, users can flexibly adjust the type, spacing, and arrangement of the buffer groove, as well as the number, angle, and welding position of the reinforcing ribs. Furthermore, by changing the material of the iron plate itself or the type and thickness of the ceramic coating, a series of product combinations can be created to meet different temperature ranges, mechanical loads, and thermal stress levels.
[0075] In summary, this utility model not only has a reasonable structure, is easy to manufacture and maintain, but also has broad industrial adaptability and extensibility. It can effectively solve the technical problems of easy deformation and damage of iron plates under high-temperature working conditions, and has significant engineering practical value and promotion prospects.
[0076] The above-described embodiments are merely preferred embodiments of the present invention and are intended to help understand the structural and functional features of the present invention. They are not intended to limit the scope of protection of the present invention.
[0077] It should be understood that all equivalent substitutions, improvements, modifications, or combinations made by those skilled in the art based on this specification without departing from the basic concept of this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the contents defined in the claims.
