Hydraulic Power Unit Solution for CNPT’s High-Precision Rolling Mill Equipment

China Nonferrous Processing Technology Co., Ltd. (CNPT), a subsidiary of Aluminum Corporation of China (Chinalco), is one of China’s leading engineering companies specializing in nonferrous metal processing technology, rolling mill equipment, industrial furnaces, and turnkey metallurgical engineering solutions.

Originally established as the Luoyang Engineering & Research Institute for Nonferrous Metals Processing, CNPT has played a significant role in the development of China’s aluminum and nonferrous metals industries for more than six decades. The company provides engineering design, equipment manufacturing, research and development, and EPC services for advanced rolling mills and metallurgical production lines.

To support the demanding hydraulic requirements of its next-generation rolling mill equipment, CNPT selected custom hydraulic power units (HPUs) engineered by Beijing Generalway as a critical component of its high-precision production systems.

The Challenge

Modern aluminum and nonferrous rolling mills rely heavily on hydraulic systems to deliver precise, reliable motion control under continuous heavy-duty operating conditions.

Applications such as Automatic Gauge Control (AGC), coilers, edge rollers, and other precision actuators require hydraulic systems capable of maintaining stable pressure, rapid response times, and exceptional operational reliability.

For CNPT, the hydraulic solution needed to:

* Deliver stable hydraulic pressure during continuous production

* Provide rapid response for precision rolling control

* Support high-load industrial applications

* Minimize system noise and energy consumption

* Improve equipment accuracy and operational stability

* Integrate seamlessly with advanced rolling mill automation systems

The project required a hydraulic power solution capable of supporting demanding metallurgical manufacturing processes while maintaining long-term reliability.

Our Solution

To meet these requirements, Beijing Generalway supplied custom hydraulic power units specifically engineered for heavy-duty rolling mill applications.

Each hydraulic power unit features an integrated modular design that combines hydraulic pumps, reservoirs, filtration systems, pressure control components, cooling systems, and intelligent monitoring into a compact, standardized package.

The systems provide highly stable hydraulic pressure with fast response characteristics, enabling precise motion control for critical rolling mill equipment, including AGC servo systems, coilers, edge rolling mechanisms, and other hydraulic actuators operating under continuous heavy loads.

Energy-efficient hydraulic circuit design helps reduce overall power consumption while maintaining consistent operating performance throughout extended production cycles. Low-noise operation further improves the working environment while contributing to reduced operating costs.

Designed for industrial reliability, the hydraulic power units integrate seamlessly with CNPT’s advanced metallurgical equipment, improving machine accuracy, production stability, and overall equipment performance.
