550mm 4Hi Precision Cold Rolling Mill Success Case: Pioneering a New Era in High-Precision Metal Processing
We are pleased to announce the successful commissioning of the 550mm 4Hi Precision Cold Rolling Mill (CRM), a milestone achievement that not only highlights the profound foundation of our strategic cooperation but also sets a new benchmark for precision in the metal processing industry. This advanced equipment enables our clients to achieve an exceptional tolerance control of ±0.003mm in the production of metal strips for high-end fields such as aerospace and precision instruments, ushering in a brand-new chapter of high-precision manufacturing.
Project Excellence Highlights
Ultra-Precision and Ultra-Thin Strip Manufacturing Capability
This cold rolling mill is specifically designed for demanding 0.03 - 1.0mm titanium alloy strips (TC4/TA15 grades) and high-temperature alloy strips (GH4169), achieving industry-leading thickness consistency of ±0.003mm, meeting the extreme precision requirements of high-end fields.
The integrated servo AGC system combined with X-ray thickness monitoring ensures a profile deviation of less than 0.2% across the entire coil length, maintaining stable quality for every inch of the strip.
The multi-segment roll cooling system can real-time adjust the temperature distribution on the roll surface, effectively controlling the dimensional fluctuations of the strip caused by temperature changes.
Smart Factory Automation System
Adopting the Fanuc 30i - B CNC control system, which has strong computing power and can preset rolling parameters for more than 150 types of materials, enabling flexible and efficient production switching.
The big data - based equipment health management system can predict potential faults by analyzing data such as current and pressure during equipment operation, reducing unplanned downtime by 30%.
The independently developed intelligent connection service platform provides 7×24 hours remote monitoring and diagnostic services, with an emergency response time of no more than 20 minutes.
Efficient Global Deployment
The 6 - week Factory Acceptance Test (FAT) was carried out in strict accordance with the ISO 14001 environmental management system standards, and a 100 - hour continuous operation test was completed to ensure stable equipment performance.
Special transport containers with constant temperature and humidity control systems were used to maintain humidity ≤45% throughout the transportation process, providing a good storage environment for the equipment.
The equipment installation and commissioning were completed in 12 days, and 20 technicians were comprehensively trained on operation and troubleshooting through the AR - assisted training system.
Significant Production Transformation
With the help of the advanced tension control system, the equipment operating speed has increased by 40% to 560 m/min, which is significantly higher than the 400 m/min of traditional equipment, greatly improving production efficiency.
The high - precision optical inspection system can accurately identify tiny defects below 5μm, reducing the scrap rate from 4.5% to 1.2%, significantly reducing production costs.
Successfully acquired the capability to produce 6μm ultra - thin strips and obtained relevant certifications in the aerospace field, laying the foundation for customers to expand into new markets.
Strategic Cooperation Advantages
✔ Joint R&D Innovation: The two parties jointly developed a customized roll bearing seat structure, which perfectly adapts to the customer's existing production line, reducing equipment transformation costs.
✔ Green and Energy - Saving Operation: Adopting high - efficiency variable frequency motor drive, reducing power consumption by 22%, which can save about 320 MWh of electricity annually.
