1. Power saving: The series-connected thyristor equipment is low power consumption. It can save20% power compared with ordinary equipment.

2. Environmental advantage: The silicon-controlled rectifier series-connected medium frequency power cabinet is robust and durable. It need not special using environment. Meantime, it is safety performance by incorporating protection measurement. Such as water pressure detection and temperature detection.

3. Quickly melting: The melting process is fast and power consumption is low.

4. Prime quality: It can work five year without fault. Maintenance is easy and repairs is simple.

5. Technique advantage: The technique is mature. Without high-order harmonics. High power factor, no need reactive power compensation devices and harmonic suppression devices.
