Background and Challenges

The metallurgical industry is characterized by high energy consumption and continuous production processes. Power systems are required to operate reliably under harsh conditions, including high temperatures, heavy dust, and strong electromagnetic interference, while also withstanding large current impacts caused by frequent load startups. The key challenges include:

High Risk of Power Interruptions

Even a momentary power disturbance in critical processes such as continuous casting and rolling can lead to production line shutdowns or product scrap.
Severe Current Surges

Equipment such as electric arc furnaces and rolling mills experience intense current fluctuations during startup, placing extremely high demands on the impact withstand capability of power equipment.
Complex Operating Environments

Harsh workshop conditions involving high temperature, dust, and vibration pose significant challenges to the long-term stability and reliability of electrical equipment.

Overview

Leveraging our leading technological strengths in the power automation and secondary equipment industry—including over 80% market share in synchronization systems and a mainstream supplier position in fast transfer solutions—we provide the metallurgical industry with an integrated “Fast Transfer + Inrush Suppression + Smart Phase Control” power system solution.

This solution is widely applicable to typical scenarios such as blast furnace power supply, continuous casting drives, and rolling mill production lines, delivering high reliability, low electrical impact, and long service life across the entire power supply process.

Key Technologies

Fast Power Supply Switching

By coordinating fast seamless power transfer devices with high-speed vacuum circuit breakers, the solution achieves a switching time of ≤20 ms, ensuring uninterrupted power supply for continuous processes such as continuous casting and rolling mills.
Strong Inrush Current Suppression Capability

Our intelligent phase-control devices utilize a "residual flux and bias flux mutual cancellation" technology to precisely control the breaker closing phase angle, significantly suppressing switching inrush currents, reducing system losses, and effectively protecting electrical equipment.
Adaptability to Harsh Operating Conditions

The circuit breakers and associated devices are certified to GB 1984 and IEC 62271-100 standards, offering strong resistance to high temperature, heavy dust, and vibration, making them well suited for the demanding environments of metallurgical plants.
Smart Diagnostics and Remote O&M

The supporting system provides event recording, waveform capture, real-time monitoring, and abnormal alarm functions, significantly improving maintenance efficiency and fault response speed.

Application Results and Cases

After deployment across key projects in steelmaking, copper, and aluminum processing, our solution has delivered significant results, including a reduction of over 95% in power outage incidents on continuous casting lines, an average decrease of 35% in electrical failure rates, and a 20% reduction in annual operation and maintenance costs. The solution is now widely applied by leading industry players such as Baowu Steel and Aluminum Corporation of China (CHALCO), supporting the safe, stable, and efficient operation of power systems throughout the metallurgical industry.
