AISCO TMT rebars are produced using the innovative "ore to core" concept within an integrated steel plant, enabling comprehensive quality control throughout the manufacturing process. The foundation of these rebars lies in sponge iron, celebrated for its low sulphur and phosphorus content, high metallic value, and uniform composition. This high-quality sponge iron is melted in furnaces that operate under stringent supervision. To uphold chemical accuracy, samples from each heating batch are meticulously analyzed, with alloys introduced to achieve the specified composition. The molten steel is then transformed into billets through a continuous casting billet machine (CCBM) and is subsequently rolled into TMT bars in cutting-edge facilities. These facilities utilize advanced quenching technology to create a ferrite-pearlite core, which guarantees optimal quality and performance of the final product.

Rebar's Ferrite-Pearlite Core

AISCO TMT rebars are produced using the innovative "ore to core" concept within an integrated steel plant, enabling comprehensive quality control throughout the manufacturing process.

Thermomechanical Treatment Process for AISCO TMT Bars

Aisco is at the forefront of reinforcement engineering, producing high-quality TMT reinforcement bars that leverage advanced technology and cutting-edge manufacturing processes. Utilizing a fully automated, high-speed rolling mill, Aisco employs the innovative quenching and tempering process, which significantly enhances the properties of its reinforcement bars. This specialized treatment not only improves yield strength and ductility but also ensures superior weldability, bendability, and resistance to corrosion and heat. As a result, Aisco's TMT bars are transforming construction practices, providing engineers and builders with reliable materials that meet the highest standards of performance and durability. Through its commitment to excellence, Aisco continues to set new benchmarks in the industry, making a substantial impact on structural integrity and safety.

Quenching: The process of quenching rebar immediately after rolling is crucial for enhancing its mechanical properties. This computerized method involves a rapid application of water sprays that cool the surface of the rebar almost instantaneously. As a result, a hardened outer layer composed of martensite is formed, providing improved strength and wear resistance. Meanwhile, the core of the rebar remains hot and in an austenitic state, ensuring that the material retains some ductility. This combination of a tough exterior and a malleable interior allows for a balance of strength and flexibility, making the rebar suitable for various construction applications. The precision of this computerized quenching process significantly contributes to the overall performance of the rebar in structural integrity and durability.

Iron Ore

Aisco places a strong emphasis on achieving top quality in its sponge iron production right from the start. The company meticulously sources premium raw materials, including high-grade iron ore, non-coking coal, and dolomite. Understanding that the quality of sponge iron is heavily influenced by the characteristics of its raw materials, Aisco implements rigorous quality checks to assess both chemical and physical properties. They prioritize selecting iron ore with high iron content and low gangue to maximize the efficiency of steelmaking. In addition to standard assessments, Aisco conducts comprehensive tests on shatter, tumbler, abrasion indices, and reducibility to ensure consistency and reliability in their products. By sourcing raw materials exclusively from reputable, high-quality mines, Aisco is able to achieve the superior results that its customers expect.

Sponge Iron

In the production of sponge iron, special care is taken to uphold several critical qualities that ensure its effectiveness and usability in various applications. Firstly, the process is designed to maintain low levels of sulphur and phosphorus, which are essential for enhancing the iron's quality. Furthermore, a uniform quality is consistently achieved, guaranteeing reliability in performance. The sponge iron produced boasts a high iron content coupled with an elevated degree of metallisation, making it highly desirable for industrial purposes. Additionally, the manufacturing process minimizes dust generation, contributing to a safer and cleaner work environment. Lastly, efforts are made to keep tramp elements negligible and gangue contents low, ensuring a superior end product that meets stringent industry standards. This meticulous attention to detail underscores the commitment to producing high-quality sponge iron.

Billets

At our fully integrated mill, we take pride in the production of high-quality sponge iron, which is efficiently cast into billets. To guarantee excellence, strict quality checks are performed at every stage of the manufacturing process, meticulously ensuring that each charge contains the required chemical composition. Samples are rigorously analyzed for every heat produced, allowing us to maintain our high standards. Once the steel billets are ready, they undergo a series of rolling stands that progressively reduce them to the desired size. Following this critical step, we initiate the three-stage process of quenching and tempering, further enhancing the steel's properties. Through this meticulous process, we ensure that our final products meet both industry standards and customer expectations.

We ensure excellence in every step of our integrated steel production process, transforming iron ore into blasted, oxygenated, refined, and tempered, sustainable, deformed steel rebar

Self-Tempering: As the bar emerges from the quenching box, the intense heat radiating from its austenitic core plays a crucial role in transforming its surface. This exposure seamlessly tempers the martensite, resulting in the formation of a resilient and robust outer layer of tempered martensite. This process not only enhances the bar's strength but also imparts toughness, making it well-suited for demanding applications. The careful interplay between temperature and phase transformation ensures that the structural integrity of the material is significantly optimized, leading to a superior end product. By harnessing the properties of both austenite and martensite, manufacturers can achieve a balance of hardness and ductility, essential for high-performance engine

Atmospheric Cooling: The advanced cooling process employed by AISCO transforms the rebar's austenitic core into a ductile ferrite-pearlite structure uniformly on an automated cooling bed. This innovative method results in rebar that features a robust outer layer combined with a flexible core, effectively balancing strength and ductility. Unlike conventionally cooled TMT bars, AISCO's process ensures a consistent circular rim along the entire length of the bar. This uniformity not only enhances the mechanical properties of the rebar but also contributes to its reliability in construction applications. As a result, AISCO's rebar stands out in the market, offering superior performance and durability that meet the demands of modern engineering standards.
