Description

Technical Field

[0001] This utility model relates to the field of steel plate technology, and in particular to a stainless steel clad steel plate. Background Technology

[0002] Stainless steel clad steel sheet is a bimetallic sheet made by composite rolling of a thicker base material, such as carbon steel or low alloy steel, and a thinner stainless steel cladding through a special process. The cladding thickness usually accounts for 10%-20% of the total thickness. It combines the corrosion resistance of stainless steel with the mechanical properties and economy of the base material. Stainless steel clad steel sheet is a high-performance composite material.

[0003] A search revealed that Chinese patent CN203937248U discloses a stainless steel composite plate. This patent addresses the issue that in existing stainless steel composite plates, where carbon steel and stainless steel are directly bonded, carbon can easily seep into the stainless steel or nickel-based alloy coating on the other side, causing pitting corrosion on the stainless steel coating surface. This results in poor corrosion resistance of the coating material, affecting its performance and lifespan. Furthermore, in industries such as papermaking, food processing, and liquid transportation, once pitting corrosion occurs in the coating, the composite plate cannot be used, leading to production disruptions and high production costs. Therefore, by adding a transitional protective layer, an intermetallic atomic bond is formed, increasing the bonding strength and preventing carbon steel from penetrating into the stainless steel coating and causing pitting corrosion on the stainless steel coating surface.

[0004] In the existing technology, when stainless steel cladding is connected to a steel plate base layer to form a composite plate, the anti-slip ability at the interlayer connection between the steel plate base layer and the stainless steel cladding is relatively weak. It is easy for the interlayer to slip due to vibration of the environment where the steel plate is located and the corrosion of air dust. This can easily cause the stainless steel cladding to fall off under long-term small displacement, thus exposing the surface of the steel plate base layer and reducing the structural strength of the composite steel plate. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stainless steel clad steel plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stainless steel clad steel plate, comprising a steel plate base layer, a clad plate fixedly connected to the upper surface of the steel plate base layer, a plurality of first reinforcing ribs and second reinforcing ribs fixedly connected to the upper surface of the clad plate, the plurality of second reinforcing ribs being disposed inside the plurality of first reinforcing ribs, and an anti-slip component being disposed on the lower surface of the clad plate.

[0007] The anti-slip assembly includes multiple locking blocks, which are fixedly connected to the lower surface of the cladding plate, and multiple locking grooves are provided on the upper surface of the steel plate base.

[0008] As a further description of the above technical solution:

[0009] The lock groove and lock block have a square cross-section. The upper surface of the steel plate base layer is provided with two sets of corrugated strips, and the number of corrugated strips is multiple. The lower surface of the cladding plate is provided with two sets of corrugated grooves.

[0010] As a further description of the above technical solution:

[0011] The lengths of the corrugated strips and corrugated grooves decrease sequentially from one side to the other, and the corrugated strips and corrugated grooves are arranged in a triangular pattern.

[0012] As a further description of the above technical solution:

[0013] The radius of the transition fillet between the crest and trough of the corrugated strip and the corrugated groove is ≥0.1mm, the wave pitch of multiple corrugated strips and corrugated grooves is ≤0.5mm, the wave height of the corrugated strip and the corrugated groove is ≥0.3mm, the locking groove engages with the locking block, and the corrugated strip engages with the corrugated groove.

[0014] As a further description of the above technical solution:

[0015] The steel plate base layer is provided with a sound-absorbing component, which includes multiple sound-absorbing grooves. The multiple sound-absorbing grooves are formed inside the steel plate base layer, and the cross-section of the sound-absorbing grooves is hexagonal.

[0016] As a further description of the above technical solution:

[0017] The silencing groove is provided with a bottom silencing pad, the upper surface of the bottom silencing pad is provided with a middle silencing pad, and the upper surface of the middle silencing pad is provided with a top silencing pad.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model, through the setting of anti-slip components, utilizes the locking block and locking groove to help position the steel plate base and the cladding plate. The cooperation of corrugated strips and corrugated grooves helps to increase the friction of the cladding plate under the action of corrugation, thereby limiting the front-back and left-right directions of the cladding plate. This makes it difficult for the composite plate to move on the surface of the steel plate base and detach from the surface of the steel plate base even under long-term vibration. This helps to improve the durability of the composite plate and enhance its structural strength.

[0022] 2. This utility model, through the setting of the sound-absorbing component, utilizes the sound-absorbing groove with a hexagonal cross-section to form a honeycomb structure, which facilitates the reflection and refraction of sound waves within the sound-absorbing groove, thereby helping to reduce noise. At the same time, under the action of the porous materials of the bottom sound-absorbing pad, middle sound-absorbing pad and top sound-absorbing pad, the sound energy is converted into heat energy through the friction and adhesion of a large number of internal micropores, which helps to further improve the sound absorption effect on the basis of the sound-absorbing groove.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] As attached Figure 1-6As shown, one embodiment of the present invention is provided: a stainless steel clad steel plate, including a steel plate base 1, a clad plate 2 fixedly connected to the upper surface of the steel plate base 1, and a plurality of first reinforcing ribs 3 and second reinforcing ribs 4 fixedly connected to the upper surface of the clad plate 2 to improve the structural strength of the stainless steel cladding. The plurality of second reinforcing ribs 4 are arranged inside the plurality of first reinforcing ribs 3 and interpenetrate with each other. An anti-slip component is provided on the lower surface of the clad plate 2.

[0033] The anti-slip assembly includes multiple locking blocks 5, which are fixedly connected to the lower surface of the cladding plate 2. Multiple locking grooves 6 are provided on the upper surface of the steel plate base 1 to improve the anti-slip capability and play a limiting role.

[0034] As attached Figure 3 As shown, the lock groove 6 and the lock block 5 have square cross sections, which facilitates their connection and engagement. The upper surface of the steel plate base 1 is provided with two sets of corrugated strips 7, and there are multiple corrugated strips 7 in a corrugated shape.

[0035] As attached Figure 2 As shown, the lower surface of the cladding plate 2 is provided with two sets of corrugated grooves 8, wherein the length of multiple corrugated strips 7 and corrugated grooves 8 decreases from one side to the other, and the multiple corrugated strips 7 and corrugated grooves 8 are arranged in a triangle. The radius of the transition radius between the crest and trough of the corrugated strips 7 and corrugated grooves 8 is ≥0.1mm, the wave pitch of the multiple corrugated strips 7 and corrugated grooves 8 is ≤0.5mm, and the wave height of the corrugated strips 7 and corrugated grooves 8 is ≥0.3mm. The locking groove 6 engages with the locking block 5, and the corrugated strips 7 engage with the corrugated grooves 8, which facilitates the improvement of the anti-slip ability of the cladding plate 2 on the front, back, left and right sides of the steel plate base 1.

[0036] As attached Figure 4 As shown, a sound-absorbing component is installed inside the steel plate base 1. The sound-absorbing component includes multiple sound-absorbing grooves 9, which are formed inside the steel plate base 1. The cross-section of the sound-absorbing grooves 9 is hexagonal, and the multiple sound-absorbing grooves 9 form a honeycomb structure. A bottom sound-absorbing pad 10 is installed inside the sound-absorbing grooves 9. A middle sound-absorbing pad 11 is installed on the upper surface of the bottom sound-absorbing pad 10, and a top sound-absorbing pad 12 is installed on the upper surface of the middle sound-absorbing pad 11. The bottom sound-absorbing pad 10 is made of glass fiber cotton, the middle sound-absorbing pad 11 is made of polyester fiber cotton, and the top sound-absorbing pad 12 is made of melamine foam. These are different porous materials that absorb sound through tiny gaps, which helps to improve the sound absorption effect.

[0037] Working principle: In use, the cladding plate 2 is placed on the surface of the steel plate base 1, and the locking block 5 is inserted into the locking groove 6. Simultaneously, the corrugated groove 8 and the corrugated strip 7 are aligned and engaged. Then, the cladding plate 2 is connected and fixed to the steel plate base 1. When the cladding plate 2 is subjected to vibration and attempts to move horizontally, it is blocked by the collision of the corrugated strip 7 within the corrugated groove 8. The corrugated strip 7, being corrugated in shape, not only limits movement horizontally but also horizontally. Combined with the engaging connection between the locking block 5 and the locking groove 6, this further enhances the anti-displacement capability of the cladding plate 2, limiting its movement horizontally, vertically, and vertically. The cladding plate 2 can be stably held on the upper surface of the steel plate base 1. When the steel plate base 1 is used for sound absorption, the sound absorption groove 9 is composed of hexagonal units, each unit forming an independent micro resonant cavity. When the sound wave enters the honeycomb structure, it will be reflected and refracted between the honeycomb walls. The sound wave energy gradually decays in repeated collisions. At the same time, the bottom sound absorption pad 10, the middle sound absorption pad 11 and the top sound absorption pad 12 made of porous material convert sound energy into heat energy through the friction and adhesion of a large number of micro pores inside, absorbing mid-to-high frequency noise, which facilitates the absorption of sound waves and thus plays a role in sound absorption.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
