Introduction: A Historic Partnership for Innovation
Danieli & C. Officine Meccaniche S.p.A. continues its legacy of pioneering technologies in the metals industry with the announcement of a new stainless steel bar-in-coil line for Fagersta Stainless. As part of the Marcegaglia Group since 2023, Fagersta Stainless, a historically significant Swedish producer, has chosen Danieli’s advanced technologies to revitalize its operations and expand its product range. This latest collaboration underscores the shared commitment to innovation, sustainability, and industry leadership.
The new line is designed to offer exceptional flexibility in product types while optimizing production processes and reducing carbon emissions. The implementation of this line demonstrates Danieli’s continued role as a reliable and innovative partner in the global steel market.
The New Stainless Steel Bar-in-Coil Line: A Technological Leap
The bar-in-coil line represents a significant advancement in the manufacturing process at the Fagersta mill. The system will not only produce round bars but also squares and hexagons, expanding the mill’s product portfolio and providing greater versatility for Fagersta’s clients.
Key Features of the Bar-in-Coil Line:
1. Product Range Expansion:
The new system will be capable of producing a variety of shapes, including rounds, squares, and hexagons. This allows Fagersta to diversify its offerings and meet the growing demand for various stainless steel profiles across different industries.
2. High Productivity and Efficiency:
Initially designed to produce 1-ton coils at a rate of 35 metric tons per hour (tph), the line’s layout has been carefully planned for future productivity increases. The line can eventually ramp up to 50 tph, and its capacity to handle double coil-weight will further increase output and efficiency.
3. Energy-Saving and Sustainability:
One of the most exciting aspects of the new line is its energy-efficient design. Danieli’s innovative process will minimize energy consumption while enhancing the microstructure uniformity of the coils. This will be achieved through a fast-transfer system, where hot coils will be quickly delivered to a water tank for solubilization, ensuring an even microstructure and improved material quality.
Moreover, the new process significantly lowers carbon emissions, positioning Fagersta as an industry leader in environmentally-friendly manufacturing.
4. Advanced Finishing Technology:
The line will utilize Morgardshammar housingless stands, ensuring a smooth and high-quality finish for the final product. These stands are already in operation in the existing rolling mill, ensuring compatibility with existing systems and streamlining the production process.
5. Future-Proofing for Growth:
Designed with scalability in mind, the line’s layout allows for future upgrades, which will enable the facility to achieve even higher productivity in line with growing market demand.
Operational Synergy with Existing Infrastructure
This new bar-in-coil line will be integrated seamlessly with Fagersta’s existing infrastructure. The hot-rolled bars produced in the same rolling mill that feeds the wirerod line will be utilized for compacting and tying operations. Leveraging the existing system helps reduce the complexity of implementation while maximizing production flexibility.
Key Integration Points:
• Compatibility with Existing Equipment:
The system will make use of the same spares and cartridges from the wirerod mill, which will reduce operational downtime and improve efficiency.
• Coil Compacting and Tying Operations:
The finishing services of the wirerod mill will be integrated into the new line, ensuring smooth and efficient coil compacting and tying.
Sustainability at the Core: Energy Savings and Reduced Carbon Footprint
Sustainability has been a key focus throughout the design and implementation of this new line. Danieli’s energy-saving process aims to optimize power consumption during production. This innovation aligns with global efforts to reduce industrial energy consumption and carbon emissions, particularly within the steel industry, which is known for its energy-intensive processes.
The rapid delivery of hot coils into the water tank ensures a uniform microstructure while minimizing energy waste. The improved process control allows Fagersta to optimize energy use, making the mill more economical and eco-friendly.
Production Flexibility and Cost-Effectiveness
The new line’s ability to produce a diverse range of stainless steel products, including rounds, squares, and hexagons, offers Fagersta increased production flexibility. This is crucial in meeting the specific demands of customers from various industries, including automotive, construction, and appliances.
In addition, the investment in the new bar-in-coil line will allow Fagersta to achieve the highest quality while maintaining competitive production costs. By using advanced technologies, Danieli has helped the mill achieve both cost savings and product quality improvements.
Future Outlook: A High-Quality, High-Output Facility
The new bar-in-coil line at Fagersta Stainless is expected to commence its hot startup in Q1 2026, marking a major milestone in the company’s growth. Once operational, the facility will be equipped to produce higher-quality products at an accelerated pace while simultaneously advancing sustainability goals.
By expanding its product range and improving operational efficiency, Fagersta will strengthen its position as a leading stainless steel producer in the global market. The successful implementation of this innovative technology is set to pave the way for further investments and upgrades at Fagersta’s mill.
