Efficient Metal Processing with Continuous Annealing Lines for Superior Surface Finish and Material Performance Our advanced continuous
annealing line delivers precision heat treatment solutions tailored for high-quality metal processing, particularly in stainless steel manufacturing. Designed to maintain surface integrity while enhancing mechanical properties, this system is ideal for industries demanding corrosion resistance, uniform hardness, and aesthetic polish. By utilizing a
bright annealing furnace environment—free from oxygen exposure—the process prevents oxidation and preserves the original luster of the material, making it perfect for applications where appearance and durability are critical. Key Features: - Oxygen-free annealing chamber ensures no oxide layer formation on metal surfaces - Integrated paper collector system with automatic stop function upon break detection - High-torque unwinder providing consistent tension control throughout the strip - Modular ABB ACS880 drive system for reliable multi-motor AC operation - Coil trolley supporting coils ranging from 610mm to 1800mm outer diameter - Common DC bus configuration for efficient energy sharing across motors Detailed Description: This continuous annealing line integrates cutting-edge engineering to optimize both productivity and product quality. The bright
annealing furnace operates under controlled atmospheres such as hydrogen or nitrogen, enabling non-oxidizing heat treatment that not only softens stainless steel but also maintains its reflective finish—a crucial advantage in consumer goods, automotive trim, and architectural components. The unwinding unit supplies precise tension to ensure smooth strip movement through the heating zone, while the coil handling trolley facilitates seamless transitions between coiling and storage positions. With a robust main drive system based on ABB’s modular technology, the line offers flexibility, scalability, and minimal downtime. The paper collector automatically halts operations if liner paper breaks during unwinding, reducing waste and preventing damage to downstream equipment. Ideal Applications: Manufacturers of cold-rolled stainless steel strips, including those producing kitchen appliances, medical devices, and industrial machinery parts, benefit significantly from this system. It supports continuous production lines requiring consistent metallurgical outcomes without compromising surface aesthetics. Whether used in flat rolling mills or integrated into broader metal finishing systems, the continuous annealing line enhances operational efficiency while meeting global standards for surface quality and mechanical consistency. User Feedback: Operators report improved yield rates due to reduced surface defects and fewer rework cycles. Maintenance teams appreciate the intuitive design of the paper detection mechanism and the reliability of the ABB-driven motor controls, which contribute to extended uptime and lower total cost of ownership over time. Frequently Asked Questions: What makes bright annealing different from conventional annealing? Bright annealing avoids atmospheric oxidation by using inert gases like hydrogen or nitrogen, preserving the metal's natural shine and preventing scale formation—unlike standard annealing, which may result in discoloration or surface degradation. Can this system handle various coil sizes? Yes, the coil trolley accommodates coils from a minimum outer diameter of 610mm up to 1800mm, offering versatility for multiple production setups. Is the drive system suitable for harsh environments? The ABB ACS880 modular drive system is engineered for industrial conditions, featuring dust-proof enclosures, thermal protection, and redundancy options for uninterrupted performance in demanding settings. This comprehensive solution combines technical excellence with practical usability, positioning your facility at the forefront of modern metalworking innovation.
