Description

Technical Field

[0001] This utility model relates to the field of metal material processing and manufacturing technology, and in particular to a SUS304 hard-state high-strength corrosion-resistant steel strip for beer. Background Technology

[0002] Metal processing and manufacturing technology is a technical field that studies how to modify the form and properties of metallic materials through processes such as plastic deformation, heat treatment, and surface treatment to meet specific application requirements. It encompasses processing methods such as rolling, forging, and stamping, and optimizes properties such as strength, hardness, and corrosion resistance by controlling the material's microstructure, providing qualified metal products for various industries.

[0003] SUS304 beer-specific steel strip is a concrete application of this technological field. Using SUS304 stainless steel as the base material, it achieves a hardened state through cold rolling and other processing techniques. It is also suitable for the lids of beverage cans that come into contact with liquids and operate at low temperatures in beer production, making it a typical example of metal processing technology specifically serving a particular industry.

[0004] However, in the existing technology, the steel strip structure of some beer can lids is mostly solid and lacks a honeycomb structure with multi-directional force dispersion paths. When the can is accidentally dropped or impacted, causing the beer to tumble and expand due to bubbles, it is impossible to evenly distribute the concentrated extrusion force. Furthermore, there is no suitable hemispherical notch to fit and fill the bottom of the deformable steel strip, making it difficult to effectively buffer energy. This can easily lead to excessive local stress, resulting in a higher risk of the beer can exploding due to a sudden increase in internal pressure.

[0005] Therefore, a SUS304 hard-state high-strength corrosion-resistant steel strip for beer production is proposed to address the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a SUS304 hard-state high-strength corrosion-resistant steel strip for beer, aiming to improve the problem that the steel strip structure of some beer can lids in the prior art is solid, which makes it difficult to disperse and buffer the extrusion pressure, and easily increases the risk of explosion due to excessive local stress.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A SUS304 hard-state high-strength corrosion-resistant beer-specific steel strip includes a steel body, an inner groove is formed inside the steel body, a plurality of soft blocks are adapted to be installed in the inner groove, and a notch is formed at the bottom of the soft blocks; As a further description of the above technical solution: The steel body is composed of multiple layers of materials, including, from bottom to top, a buffer layer, a high-strength layer, a corrosion-resistant layer, and a base layer; As a further description of the above technical solution: The embedded groove is interference-fitted with multiple soft blocks to ensure that the soft blocks are securely installed on the steel body; As a further description of the above technical solution: The soft block has a honeycomb structure with multi-directional force dispersion paths, and the notch has a hemispherical structure. When the bottom end of the steel strip is squeezed and deformed, it can be adapted to fill the notch to form a buffer protection. As a further description of the above technical solution: The buffer layer is a shape memory polymer foam buffer layer that has a preliminary buffering effect against external impacts. As a further description of the above technical solution: The high-strength layer is a cold-rolled high-strength low-alloy steel high-strength layer that has high strength but does not affect the local deformation effect of the steel strip; As a further description of the above technical solution: The corrosion-resistant layer is a graphene-modified stainless steel corrosion-resistant layer that has the effect of hindering the penetration of corrosive media and promoting the repair of passivation film. As a further description of the above technical solution: The base layer is a low-carbon steel base layer that provides stable foundation support.

[0008] This utility model has the following beneficial effects: 1. In this utility model, the honeycomb structure of the soft block has a multi-directional force dispersion path. When the beer can is accidentally dropped or impacted, causing the beer to roll and expand due to bubbles, the concentrated extrusion force can be evenly distributed to each honeycomb unit. With the matching filling of the hemispherical notch and the bottom end of the deformable steel strip, the energy can be effectively buffered and the excessive local stress can be avoided, thereby significantly reducing the risk of the beer can exploding due to the sudden increase in internal pressure.

[0009] 2. In this utility model, the steel strip adopts a multi-layer composite material structure. The shape memory polymer foam of the buffer layer can initially absorb the expansion and extrusion pressure. The cold-rolled high-strength low-alloy steel of the high-strength layer ensures the overall high strength without hindering local deformation. The graphene-modified stainless steel of the corrosion-resistant layer can resist corrosion to extend the service life. The low-carbon steel of the base layer can provide stable support. With the synergistic effect of multiple materials, the impact resistance, deformation adaptability, corrosion resistance and structural stability of the steel strip are greatly improved, meeting the long-term use requirements of beer can tops.

[0012] 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.

[0013] Reference Figures 1 to 4 This utility model provides an embodiment of a SUS304 hard-state high-strength corrosion-resistant beer-specific steel strip, comprising a steel body 1. An embedded groove 2 is provided inside the steel body 1 to provide installation space for soft blocks 3. Multiple soft blocks 3 are fitted into the embedded groove 2, with an interference fit between the embedded groove 2 and the multiple soft blocks 3 to ensure that the soft blocks 3 are securely installed on the steel body 1. This allows the soft blocks 3 to stably exert a multi-directional force dispersion effect when the steel strip is compressed. The soft blocks 3 have a honeycomb structure with a multi-directional force dispersion path, which can evenly disperse the concentrated extrusion force caused by the expansion of bubbles generated by beer tumbling to each honeycomb unit. A notch 4 is provided at the bottom end of the soft blocks 3. The notch 4 is a hemispherical structure that can be fitted and filled to the bottom end of the compressed steel strip. When the bottom end of the steel strip is compressed and deformed, it can be fitted and filled to form a buffer protection, further buffering energy and avoiding excessive local stress.

[0014] The steel body 1 is composed of multiple layers of materials, from bottom to top including a buffer layer 5, a high-strength layer 6, a corrosion-resistant layer 7, and a base layer 8. The buffer layer 5 is a shape memory polymer foam buffer layer that initially buffers external impacts. It absorbs the compressive force of bubble expansion through its own deformation, reducing the energy transmitted to the interior of the steel body 1 and forming the first layer of protection. The high-strength layer 6 is a cold-rolled high-strength low-alloy steel high-strength layer that has high strength but does not affect the local deformation effect of the steel strip. While ensuring the overall high strength of the steel strip, its good ductility does not hinder local deformation, ensuring that the buffer structure can function properly. The corrosion-resistant layer 7 is a graphene-modified stainless steel corrosion-resistant layer that hinders the penetration of corrosive media and promotes the repair of passivation films. It can resist corrosive factors in the beer storage environment and extend the service life of the steel strip. The base layer 8 is a low-carbon steel base layer that provides stable basic support and ensures the stability of the collaborative work of each layer.

[0015] Working principle: When a beer can is accidentally dropped or impacted by an external force, causing the beer inside to churn and further expand, the buffer layer 5 at the bottom of the steel strap lid first comes into contact with the expanding bubbles caused by the churning beer and then takes effect. The shape memory polymer foam material initially absorbs the compressive force of the expanding bubbles through its own deformation, reducing the energy transmitted to the interior of the steel body 1, forming the first layer of protection.

[0016] If the extrusion pressure continues to be transmitted, the bottom end of the steel strip will deform under the pressure. At this time, multiple soft blocks 3, which are interference-fitted in the groove 2 inside the steel body 1, begin to intervene. The honeycomb structure of the soft blocks 3, with its multi-directional force dispersion path, evenly distributes the concentrated impact force to each honeycomb unit. At the same time, the hemispherical notch 4 fits and fills the deformed bottom end of the steel strip, further buffering the energy through structural fit and avoiding excessive local stress that could cause the beer can to explode.

[0017] In terms of overall performance support for the steel strip, multiple layers of materials work synergistically from bottom to top: the high-strength layer 6 above the buffer layer 5 is made of cold-rolled high-strength low-alloy steel, which ensures the overall high strength of the steel strip while its good ductility does not hinder local deformation, ensuring that the buffer structure can function properly; the corrosion-resistant layer 7 above the high-strength layer 6 is made of graphene-modified stainless steel, which resists corrosive factors in the beer storage environment by hindering the penetration of corrosive media and promoting the repair of passivation film, thus extending the service life of the steel strip; the topmost base layer 8 is made of low-carbon steel, which provides stable structural support and ensures the stability of the synergistic work of each layer of materials.

[0018] 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.
