Description

[0001] STEEL PRODUCT AND ITS PRODUCING METHOD THEREOF

[0002] TECHNICAL FIELD OF THE INVENTION

[0003] The embodiments of the present invention pertain to the broad technical domain of construction, with a specific focus on the development of steel products tailored for utilization in concrete and building construction. More precisely, the invention is directed towards a long steel product and its associated production method, characterized by elevated levels of yield strength, and ductility.

[0004] BACKGROUND OF THE INVENTION

[0005] In the realm of construction, the utilization of steel is indispensable, particularly when integrated with concrete to fortify or strengthen the structural framework of buildings. The quest for constructing sturdy and robust structures propels the necessity for high-strength steel, ensuring that the resultant structures can withstand diverse loads and stresses.

[0006] Traditionally, the enhancement of steel strength involves methods such as hot-rolling or heat treatment, notably the Tempcore process. While effective in producing high-strength steel bars, this approach introduces a host of intricacies. The Tempcore process requires sophisticated machinery, intricate mechanisms, and a series of procedures including pre-heating treatment, rapid cooling, re-heating, and others, all of which contribute to elevated production costs. The resulting quenched and tempered structure, while enhancing strength, adds layers of complexity to the manufacturing process.

[0007] Another prevalent method involves the introduction of expensive alloying elements such as Ti, V, Nb, and others into the steel matrix, augmenting its properties. However, the reliance on alloying elements comes at a significant cost, as these materials are often expensive. Consequently, the production costs surge, leading to higher prices for the final steel product. Additionally, this approach typically being carried at steel making process akin to the Tempcore process, which belongs to upstream steel manufacturing processes.

[0008] Despite the effectiveness of these conventional methods in creating high-strength steel, they fall short in addressing a critical concern, i.e., low ductility. Ductility, or the ability of a material to withstand plastic deformation, is paramount in regions prone to seismic activity. Conventional high-strength steel, while robust, tends to exhibit low ductility, making it susceptible to sudden and brittle fractures during earthquakes. This inherent brittleness poses a significant risk, as it can lead to the rapid collapse of structures, endangering lives and property.

[0009] Conventionally, the manufacturing of steel product as disclosed in US 4923528, CN 1061550 and ASHRAFI, H„ et al. (2015) involve heat treatment followed by cold deformation or cold deformation with lower- temperature recovery annealing. However, the present invention eliminates the need for initial heat treatment by starting with a cold reduction process at room temperature and subsequently undergoes high-temperature annealing, which leads to a balanced micro structure of ferrite and pearlite. Additionally, the present invention offers a more simplified and cost- effective production method by bypassing the hot rolling and quenching steps.

[0010] In response to these challenges, the present invention aims to reshape the conventional approach by introducing a novel steel product and an innovative production method. The objective is to offer a solution that combines high yield strength, and ductility without the complexities and drawbacks associated with conventional methods. This advancement not only ensures improved structural resilience but also assures economic feasibility, meeting the dual requirements of safety and cost-effectiveness in construction procedures, especially in areas susceptible to earthquakes.

[0011] SUMMARY OF THE INVENTION

[0012] The present invention revolutionizes construction practices by introducing a groundbreaking long steel product and an innovative production method. This novel approach addresses the critical need for high-strength steel in building construction, particularly when integrated with concrete. Unlike traditional methods involving hot-rolling or costly alloying elements, our invention offers a unique combination of high yield strength, and ductility without the associated complexities and drawbacks.

[0013] Accordingly, it is the primary objective of the present invention to provide an enhanced structural solution for building construction that combines high yield strength, and ductility. This unique combination prolongs the time before structural failure, offering increased safety and evacuation opportunities during seismic events.

[0014] It is yet another objective of the present invention to streamline the manufacturing process, eliminating the need for elaborate machinery and intricate procedures. This results in a more economically viable solution for high-strength steel production, reducing overall construction costs without compromising on performance.

[0015] It is yet another objective of the present invention to overcome the limitations of conventional methods by maintaining excellent ductility in the high-strength steel product. This characteristic is crucial in earthquake- prone regions, as it prevents brittle fractures and enhances the overall seismic resilience of structures.

[0016] It is yet another objective of the present invention to eliminate the reliance on costly alloying elements, providing a cost-effective alternative for the production of high-strength steel. By doing so, the invention not only reduces the economic burden on construction projects but also broadens the accessibility of advanced structural materials.

[0017] It is yet another objective of the present invention to enhance the safety and structural integrity of buildings without compromising on the economic feasibility of construction projects. This unique combination of advantages positions the invention as a transformative solution for the construction industry, particularly in earthquake-prone regions.

[0033] DETAILED DESCRIPTION OF THE DRAWINGS In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by the person having ordinary skill in the art that the invention may be practised without these specific details. In other instances, well known methods, procedures and / or components have not been described in detail so as not to obscure the invention.

[0034] The invention will be more clearly understood from the following description of the embodiments thereof, given by way of example only with reference to the accompanying drawings, which are not drawn to scale. As used in this disclosure and the appended claims herein, the singular forms "a", "an", and "the" include plural referents unless the context clearly dictates or denotes otherwise.

[0035] Throughout the disclosure and claims of this specification, the word "comprise" and variations of the word, such as "comprising" and "comprises," means "including but not limited to," and is not intended to exclude, for example, other components, integers or steps. "Exemplary" means "an example of" and is not intended to convey an indication of a preferred or ideal embodiment, "such as" is not used in a restrictive sense, but for explanatory purposes. The embodiments of the present invention center around a method for producing a steel product, specifically designed for reinforcing concrete in various building constructions, with a particular emphasis on earthquake-resistant structures. This innovation introduces an improved structural element suitable for beams, columns, and other load-bearing components. The steel product seamlessly integrates into established construction methods and is adaptable to different concrete formulations. Consequently, the invention provides a distinctive and inventive response to the challenges presented by seismic events in construction, enhancing the ability of buildings to resist collapse during earthquakes and, in turn, ensuring the safety of occupants.

[0036] This invention can be made into welded mesh product or any form of fence, or steel products which is used in critical application such as mining industry, underground working environment, prevention soil movement at hilly or slope area and etc.

[0037] Within this document, the term "steel product" or "steel component" encompasses various forms, including but not limited to, long steel, steel bars, rods, wire rods, rebars, or other variants or counterparts. The definition specifically targets products characterized by an elongated form relative to their cross-sectional dimensions, tailored for extended lengths suitable for construction purposes where elongated steel sections are essential, such as in beams, columns, or structural elements of buildings. This terminology emphasizes the elongated quality of these steel components, distinguishing them from shorter, more compact forms like sheets or plates.

[0038] Depicted in FIG. 1 is an exemplary method flow (100) illustrating the production of a steel product designed for reinforcing concrete. The process initiates with the step for selection of raw materials (110), emphasizing the careful design of the material's chemical composition as a foundation for subsequent steps. In one embodiment, the present invention opts for raw materials whose chemical composition and mechanical properties align with the specifications outlined in Standard AS / NZS 4671:2019, as detailed in TABLE 1 and TABLE 2:

[0039] Table 1

[0040]

[0041] Table 2

[0042] Ideally, the chosen raw material is a steel rod, with a preference for readymade hot-rolled carbon steel rods featuring an iron (Fe) content ranging between 98% and 99%. The major elements outlined in contractual agreements, specifications, or technical protocols typically include Carbon (C), Silicon (Si), Manganese (Mn), Phosphorus (P), and Sulphur (S). The preferred embodiment of the present invention targets a reinforced steel product conforming to the 500E Standard. Hence, in order to enhance the mechanical properties of the final steel product or meet the required mechanical properties of the Standard, the present method has further executed controls over the chemical composition of the standard, wherein the controls over the chemical composition lies in the mass percentage of each material. This involves specific controls, such as maintaining Carbon within the range of 0.17% to 0.22%, Silicon between 0.05% and 0.3%, and Manganese between 0.80% and 1.2%. This innovative chemical combination is anticipated to elevate the mechanical properties of the final steel product in terms of material strength, total elongation at maximum force (AGT) or ductility. Therefore, the stringent selection and control of raw materials stand as pivotal criteria to ensure that the mechanical properties of the final product align with the specifications outlined in the 500E standard.

[0043] Following the selection of raw materials (110), the subsequent step involves subjecting the raw material to a cold working or cold reduction process (120), specifically conducted at room temperature, a departure from conventional heat treatment methods. It is crucial to underscore that this process occurs at room temperature, eliminating the need for heating, cooling, or any complex apparatus. The cold working process (120) aims to deform and reduce the size of the steel rod, particularly its diameter, with observable grain elongation and size reduction. This process significantly alters the mechanical properties, for both strength and ductility. As indicated in TABLE 3 below, the tensile strength increases from the range of 600-700 N / mm2to the range of 800-1000 N / mm2after cold working. However, despite the augmented material strength, ductility (AGT) experiences a substantial reduction from the range of 10.0-16.0% to the range of 1.0-3.0%. It is important to note that the raw material, steel rod is transformed into cold-deformed wire after the cold working or cold reduction process.

[0044] Table 3

[0045] At this stage, while the cold-deformed wire exhibits increased strength, its low ductility makes it prone to breakage under maximum loads, as it lacks the capacity for elongation. In addition to material strength, the consideration of ductility becomes paramount, particularly in applications involving concrete, particularly in seismic -prone areas. While cold working has been demonstrated to elevate material strength, the methodology of the present invention extends beyond this point. It is imperative not to compromise on ductility while enhancing material strength, given its critical role in ensuring the structural integrity and safety of constructions, particularly in regions susceptible to earthquakes. Therefore, the present method places a strong emphasis on concurrently enhancing both material strength and ductility, acknowledging their complementary importance in construction applications, particularly those exposed to seismic risks. Recognizing the significance of ductility, especially in seismic regions, the method does not conclude with cold working alone, aiming to enhance material strength without compromising ductility.

[0046] The cold working process can manifest in two forms: cold drawing or cold rolling. Cold drawing entails pulling the raw material through a die apparatus with an adjustable diameter, aiming to reduce the diameter of the raw steel rod, as illustrated in FIG. 2-A. Conversely, the cold rolling process involves the utilization of at least two rollers to roll the raw material, mirroring the principles of cold drawing, as illustrated in FIG. 2-B. In the cold rolling process, specific marks may be imprinted on the rollers. Consequently, when the raw steel rod is rolled through, these marks can be transferred onto the steel wire, serving as a means of product differentiation. This imprinting not only facilitates identification but also acts as a distinguishing feature, exemplified in FIG. 3.

[0047] Following the cold working process, the cold-deformed wire undergoes a subsequent annealing process (130), strategically designed to restore the wire from the earlier cold deformation, aiming to enhance ductility or AGT performance without compromising material strength excessively. This annealing process (130) takes place within a furnace, where the cold-deformed wire is drawn into an annealing furnace. The temperature control and duration of the annealing process are crucial for effective material recovery. The temperature is preferably maintained within the continuous range of 700-850°C for a duration of 40-120 seconds. This ensures a balanced annealing of each part of the wire, from head to tail, in accordance with the run speed. The combination of the annealing duration and controlled temperature results in material recovery with a slight decrease in material strength and a significant increase in ductility.

[0048] Table 4

[0049] As depicted in TABLE 4, the annealed wire exhibits notable changes, with tensile strength decreasing from the range of 800-1000 N / mm2f0600-750 N / mm2anc| yield strength dropping from the range of 700-950 N / mmzf0500-600 N / mm2. Conversely, ductility (AGT) experiences a substantial increase from the range of 1.0-3.0% to at least 10.0%. The final steel product maintains a ferrite + pearlite structure, indicative of partial recrystallization occurring in the material during annealing. This annealed material showcases a controlled partial grains recovery, facilitating recovery from cold deformation. In this unique process, material strength experiences a reduction, while ductility improves to the targeted level, termed as the "hybrid-recrystallization process." This process balances and addresses both material strength and ductility throughout the cold deformation and annealing stages.

[0050] As illustrated in FIG. 4, in a particular embodiment, the final steel product undergoes an ageing process (150), preferably conducted at room temperature. Subsequently, the steel product is ready for subsequent processes or applications. In a specific embodiment depicted in FIG. 5- A, the method (100) may include an additional step of galvanizing the annealed wire (140), performed after the annealing process (130) illustrated in FIG. 1. In cases where the finished product necessitates ageing process (150), as shown in FIG. 4, the galvanization of the annealed wire (140) takes place after the annealing step (130) but before the ageing step (150), as demonstrated in FIG. 5-B. Further elaborating on the galvanization process, as depicted in FIG. 5-C, it involves a series of sub-steps. Initially, the annealed wire undergoes acid pickling (141), followed by fluxing (42), immersing (143), quenching (144), waxing (145), culminating in the production of a galvanized wire. This comprehensive galvanization sequence ensures the protective coating of the annealed wire, enhancing its resistance to corrosion and contributing to its overall durability and longevity.

[0051] Acid pickling (141) refers to a metal surface treatment process that involves immersing the annealed wire, in an acid solution to remove oxides, scales, rust, and other impurities from its surface. The acid used in the pickling process reacts with the metal oxides, dissolving them and leaving behind a clean metal surface. Common acids used in the pickling process include hydrochloric acid (HC1) or sulfuric acid (H2SO4), depending on the specific requirements of the metal and the desired outcome of the treatment.

[0052] In the galvanization process, after acid pickling, fluxing (142) is the next step. Fluxing (142) involves applying a flux solution to the surface of the annealed wire, typically after it has been cleaned and pickled. The primary purposes of fluxing are neutralization and protection. It neutralizes any remaining acidic residues on the surface from the pickling process. This is important because acidic residues can adversely affect the effectiveness of the subsequent steps in the galvanization process. It also forms a protective layer on the surface to prevent reoxidation. This protective layer helps maintain the cleanliness of the annealed wire before it is immersed in the molten zinc during galvanization. Common flux solutions include zinc ammonium chloride or zinc ammonium chloride hydroxide. These solutions not only neutralize the surface but also provide a layer of protection to prevent the formation of oxides on the metal before it undergoes the galvanization bath or the hot dip galvanizing process.

[0053] Subsequently, the annealed wire undergoes the hot-dip galvanizing process (143), a process for coating the annealed wire with a layer of zinc to provide corrosion protection. The process involves immersing the annealed wire into a bath of molten zinc typically at a high temperature, preferably at least 450°C, thereby ensuring a uniform and complete coating, covering all surfaces of the annealed wire. The high temperature of the bath allows the zinc to metallurgically bond with the metal surface, forming a series of zinciron layers. The hot-dip galvanized coatings act as a sacrificial anode, corroding preferentially to protect the underlying metal, and they are known for their durability and longevity, providing robust protection even in harsh environments. After the annealed wire is withdrawn from the process of hot-dip galvanizing, it may undergo a quenching process (144). Quenching (144) involves rapidly cooling the annealed wire to solidify the zinc coating. This is typically achieved by immersing the annealed wire in water or other quenching solutions. The rapid cooling solidifies the zinc coating, ensuring its adherence to the metal surface. Quenching contributes to the uniformity and adhesion of the zinc coating, reducing the risk of coating imperfections and influence the micro structure of the zinc coating, contributing to its overall quality and corrosion resistance.

[0054] The final step involves the application of a specialized wax coating to the galvanized steel (145). This wax serves as an additional protective layer, helps to seal any microscopic pores or imperfections in the galvanized coating, providing enhanced protection against corrosive elements, minimize the formation of wet storage stains during transportation and storage, particularly in humid conditions, contribute to a smoother and more aesthetically pleasing appearance, which is desirable in architectural and decorative applications, and acts as an extra barrier against moisture, chemicals, and other environmental factors, further extending the corrosion protection of the galvanized steel.

[0055] In an alternative embodiment of the present invention, the final steel product derived from all preceding embodiments undergoes a subsequent process known as mesh making(160), as further elucidated in FIG. 6. This mesh making process (160) entails a series of steps, beginning with wire straightening (161) to ensure uniformity and precision. Following straightening step (161), the straightened annealed wire is precisely cut to a pre-determined length (163), adhering to specific dimensional requirements for the intended application. Subsequently, the process involves wired mesh welding (165), where the individual wires are seamlessly welded together, culminating in the creation of a welded mesh ready for subsequent processes or applications. This comprehensive mesh making procedure (160) adds versatility to the final steel product, facilitating its tailored use in various construction applications.

[0056] Table 5

[0057] In an alternative embodiment of the present invention, the selection of raw material adheres to the chemical composition specifications outlined in Standard MS146:2014, as illustrated in TABLE 5. Standard MS146:2014 is the Malaysian Standard that specifies the requirement and criteria for construction material. This standard contains provisions for three steel grades, all of 500 MPa characteristic yield strength, but with different ductility characteristics. The three grades are B500A, B500B and B500C. Despite this distinct raw material choice, the subsequent manufacturing / producing process remains consistent with the methods detailed in all preceding embodiments. Ideally, the preferred raw material is a steel rod, with a preference for ready-made hot-rolled carbon steel rods containing an iron (Fe) content ranging between 98% and 99%. The major elements, including Carbon (C), Silicon (Si), Manganese (Mn), Phosphorus (P), Nitrogen (N), Copper (Cu), and Sulphur (S), are governed by contractual agreements, specifications, or technical protocols.

[0058] This particular embodiment targets a reinforced steel product conforming to the 500B and / or 500C Standard. To align with the mechanical properties required for this standard, the method incorporates controls over the chemical composition, specifying mass percentages for each material. This involves precise controls, such as maintaining Carbon within the range of 0.17% to 0.22%, Silicon between 0.05% and 0.2%, and Manganese between 0.60% and 1.0%.

[0059] In contrast to the earthquake-resistant application emphasized in the first embodiment, this composition is intended for use in the general construction industry. Consequently, the mechanical properties of the final product differ from the initial embodiment. Additionally, the identification method varies, with distinctive patterns or styles applied through the cold rolling process, as showcased in FIG. 7. Another point of differentiation lies in the annealing time during the annealing process, which ranges between 20-100 seconds in this embodiment. These nuances highlight the adaptability of the present invention to cater to specific industry requirements and standards.

[0060] The mechanical properties mandated for the final annealed wire, in compliance with the 500B and / or 500C Standard, necessitate a minimum yield strength of 500 N / mm2. Furthermore, the final annealed wire of 500B should exhibit a minimum 5.0% AGT, while the final annealed wire in the 500C category must achieve at least 7.5% AGT. The present invention's methods effortlessly fulfill these requirements, ensuring that the final annealed wire easily meets the specified criteria. A final annealed wire surpassing 7.5% AGT can be designated as 500C grade or labelled as 500C steel wire, while an AGT ranging from 5% to 7.5% qualifies it as 500B steel wire.

[0061] It is crucial to emphasize that in the current market landscape, producing a steel wire meeting the 500A standard, which demands only a 2.5% AGT, is relatively straightforward. However, the noteworthy achievement lies in the fact that there is currently no entity capable of manufacturing a steel product that conforms to the more stringent standards of 500B and 500C. The present invention takes pride in the capability, using its innovative methods, to label the final steel wire as 500B or 500C steel wire. The mechanical properties for a steel product to conform with the standard is shown in TABLE 6. . .

[0062] Table 6

[0063] However, it is crucial to acknowledge that the Standard AS / NZS 4671:2019 or Standard MS146:2014 is subject to periodic revisions by the relevant authority, potentially involving changes in chemical composition or mechanical properties. Nonetheless, the methods employed by the present invention remain adaptable and capable of producing a steel wire that aligns with any revisions introduced in the standards. A crucial aspect of the present invention lies in its deliberate exclusion of expensive alloying elements to augment mechanical properties. Furthermore, it is noteworthy that the methodology does not necessitate any initial heat treatment or involve multiple treatment steps to achieve the final product. This distinctive approach underscores the efficiency and simplicity of the invention, as it prioritizes a streamlined process that achieves enhanced mechanical properties without relying on expensive alloying elements or intricate heat treatment procedures.

[0064] Furthermore, it is particularly remarkable that the final annealed wire yielded from the present method (100) can be tightly coiled into a compact configuration, unlike the loosely wound configuration typically found in wires manufactured through conventional methods. This distinction is illustrated in FIG. 8, depicting the compact coil configuration, and FIG. 9, depicting the loose coil configuration. These compact coils not only save space but also allow for the production of heavier coil weights while maintaining a similar coil size. This aspect is advantageous for continuous production, as larger coil weights can be accommodated, and it is also beneficial for logistics, especially in terms of export or transportation. Conventional processes face challenges in achieving this outcome due to their reliance on hot rolling techniques. While the present invention has been shown and described herein in what are considered to be the preferred embodiments thereof, illustrating the results and advantages over the prior art obtained through the present invention, the invention is not limited to those specific embodiments. Thus, the forms of the invention shown and described herein are to be taken as illustrative only and other embodiments may be selected without departing from the scope of the present invention, as set forth in the claims appended hereto. The scope of the invention encompasses numerous alternatives, and modifications. Of necessity, there are many alternative ways of configuring and implementing the invention to suit particular installations and environments while providing biological outcomes of differing design.
