The HR slitting line is a critical component of our manufacturing process, designed to enhance the precision and quality of our products. This advanced equipment cuts the rough edges of the hot-rolled (HR) coils, meticulously slitting them into narrower widths to meet the specific requirements of our diverse customer base.
Our HR slitting line is equipped with the latest technology, ensuring high accuracy and efficiency. It can handle a wide range of coil thicknesses and widths, allowing us to cater to various industrial applications. The process involves passing the HR coils through a series of rotary knives, which are precisely aligned to deliver clean, burr-free edges. This not only improves the aesthetic appeal of the final product but also enhances its performance and usability in subsequent manufacturing processes.
The pickling line at Hero Steels is an essential part of our production process, designed to enhance the quality and surface finish of our hot-rolled (HR) coils. This line effectively removes ferrous scale from the surface of the HR coils, ensuring that the final product is clean, smooth, and ready for further processing.
Our state-of-the-art pickling line utilizes a series of three acid tanks, where the coils are immersed in a carefully controlled acidic solution that dissolves the oxide layers and other impurities. This thorough cleaning process is crucial for preparing the steel surface for subsequent treatments, such as galvanizing or painting, ensuring optimal adhesion and performance.
At Hero Steels, our pickled HR coils are cold rolled to the required thickness using advanced 6-Hi and 4-Hi mills. The 6-Hi mill features automatic gauge control (AGC), pass schedule storage, and Auto Slow Down (ASD), ensuring consistent thickness, optimized rolling sequences, and smooth finishes. Our 4-Hi mill complements this with robust performance and excellent control over thickness and shape.
Both mills deliver flat strips with minimized edge drops and achieve thinner gauges with high accuracy. Operated by skilled professionals, our mills ensure each coil meets stringent quality standards. Advanced automation and control systems enhance productivity and consistency, allowing us to meet diverse customer requirements with precision and efficiency.
In summary, our cold rolling process exemplifies our dedication to precision, quality, and high-performance products, reinforcing Hero Steels as an industry leader.
At Hero Steels, our annealing process enhances the properties of our steel products through heating, soaking, and controlled cooling in a non-oxidizing, 100% hydrogen atmosphere. This ensures a clean, bright surface finish and prevents oxidation.
The process begins with heating the coils to a specific temperature to reach the recrystallization point. The coils are then soaked uniformly to stabilize the internal structure. After soaking, controlled cooling prevents stress or distortion, achieving the desired balance of hardness and flexibility.
Our advanced monitoring systems ensure consistent treatment, resulting in high-quality steel products that meet our rigorous standards. In summary, our precise annealing process guarantees enhanced mechanical properties and superior surface quality.
At Hero Steels, our skin passing process is essential for refining the quality of our steel strips. This process removes stretcher strain or Luder lines, ensuring a smooth and uniform surface. By lightly cold rolling the strip, we achieve the desired finishes, such as matte or bright, to meet specific customer requirements.
Skin passing also imparts flatness to the strip, correcting minor shape defects and ensuring consistent thickness. This step is crucial for achieving the high standards of flatness required for many industrial applications.
In summary, our skin passing process eliminates surface imperfections, provides specific finishes, and ensures flatness, resulting in high-quality steel products suitable for a wide range of uses.
Our cold rolled slitters are essential for customizing strip widths to meet customer demands. Equipped with an advanced electrostatic oiling spray system from ECT, USA, they ensure precise and uniform lubrication during the slitting process.
These machines enable us to tailor strip widths accurately, catering to a range of customer requirements. The electrostatic oiling system enhances quality by minimizing friction and surface defects, guaranteeing high-quality steel strips that exceed industry standards.
Operated by skilled technicians, our cold rolled slitters deliver precision and consistency, meeting even the most demanding specifications. With this capability and technology, Hero Steels stands as a reliable partner for fulfilling diverse customer needs.
Our cut-to-length process is instrumental in transforming cold rolled steel strips into sheets of the precise length and width required by our customers. This critical step ensures that the steel sheets are tailored to fit seamlessly into their intended applications, whether for construction, manufacturing, or other industrial uses.
At Hero Steels, we employ advanced cutting equipment and techniques to achieve accurate and consistent results. Our state-of-the-art machinery is capable of cutting steel strips with precision, allowing us to meet the exact specifications provided by our customers.
