Yirui New Materials Installs Mill Housing for 720kt Project

June 20, 2026 – Yirui New Materials achieved a critical construction milestone at its 720,000-ton intelligent aluminum project: the roughing mill housing – the core load‑bearing unit of the hot rolling line – was successfully hoisted and precisely positioned in a single, high‑accuracy lift. This operation marks the transition from civil works to intensive equipment assembly, setting the stage for full‑scale commissioning.

At a Glance: Project & Milestone

- Total capacity: 720,000 tons per year of advanced aluminum sheet and strip  

- Key equipment installed: Roughing mill housing (weight > 200 tons)  

- Installation date: June 20, 2026  

- Significance: Enables subsequent assembly of auxiliary components, line integration, and trial production  

- Strategic goal: Expand high‑precision, wide‑width aluminum capacity for automotive, rail, and smart equipment sectors

Precision Installation: Why It Matters

The roughing mill housing is not just a heavy steel structure – it is the structural heart of the hot tandem rolling line. It bears the entire rolling force during deformation, directly dictating:

- Rolling accuracy (thickness and flatness tolerances)  

- Operational stability (vibration damping and alignment)  

- Final surface quality (defect‑free coils for high‑end applications)

Among all installation tasks, this step ranks highest in technical difficulty. The team had to manage extreme weight, confined workspace, and micron‑level alignment tolerances. Through real‑time laser tracking and precision rigging, they achieved a one‑time, drift‑free placement – no repositioning was needed, saving critical schedule time.

Overcoming Technical Hurdles

Three major challenges were successfully addressed during the hoisting operation:

1. Heavy‑load maneuvering – The housing weighed over 200 tons. Specialized cranes and custom spreader beams were used to navigate a tight plant layout without compromising safety.

2. Micron‑level alignment – The base plates required flatness within 0.05 mm/m. Laser interferometry and continuous monitoring ensured every bolt hole matched the pre‑embedded anchors.

3. Single‑lift execution – Any rework would have delayed downstream tasks. The team pre‑simulated the lift using 3D modeling, eliminating uncertainties and achieving pinpoint accuracy on the first attempt.

With these hurdles cleared, the foundation is now solid for assembling the remaining mill components, running full‑line no‑load tests, and eventually rolling the first coils.

The 1+4 Hot Tandem Line – A Strategic Asset

This line is the flagship of Yirui’s transformation toward intelligent, green manufacturing. It incorporates:

- Advanced process control – Dynamic adjustment of rolling parameters (speed, force, lubrication) for consistent mechanical properties across coils.  

- Automation & data integration – Real‑time sensors feed back to a central MES, enabling predictive maintenance and quality traceability.  

- Energy efficiency – Regenerative drives and optimized cooling reduce power consumption per ton by approximately 15% compared to conventional lines.

Once operational, the new line will significantly boost Yirui’s ability to produce wide‑format (up to 2,800 mm) aluminum plates with tight gauge tolerances – a product segment currently in high demand yet under‑supplied in both domestic and export markets.

Driving Lightweight Industries with High‑Performance Aluminum

The new capacity directly serves the global trend toward lightweighting – reducing vehicle and equipment weight to cut emissions and improve efficiency. Key downstream sectors include:

- New Energy Vehicles (NEVs)  

  Battery enclosures, body panels, and crash‑management systems that require high strength‑to‑weight ratios and excellent formability.

- Rail Transit  

  High‑speed train car bodies and subway structural components, where fatigue resistance and corrosion protection are paramount.

- Smart Equipment & Robotics  

  Precision machined parts for automation arms, CNC frames, and semiconductor manufacturing tools – all demanding superior flatness and dimensional stability.

By aligning production with these growing markets, Yirui positions itself as a reliable partner for customers seeking consistent quality, shorter lead times, and sustainable sourcing.

Future Outlook: Growth and Global Competitiveness

Beyond capacity expansion, this project represents a strategic leap in new quality productive forces – leveraging digitalization, big‑data analytics, and intelligent decision‑making to optimize every stage from melting to finishing. The benefits are tangible:

> “With this line, we are not just adding tons – we are adding intelligence. Every coil will carry a digital footprint, ensuring full traceability and performance predictability.” – Project Lead

The successful installation of the roughing mill housing is more than a construction feat; it signals Yirui’s commitment to technological leadership and customer‑centric innovation. As the project moves toward hot‑test and ramp‑up in the coming months, the company is poised to strengthen its competitive moat in the global aluminum market, delivering high‑value solutions that meet the most stringent quality and environmental standards.
