Medium & High Voltage VFD Solutions for Metallurgy Industry
Heavy-duty anti-corrosion inverters for smelting, casting and metal rolling full production line
- Smelting workshops sustain persistent high temperature, corrosive smoke and heavy dust, ordinary inverters are easy to fail
- Smelting furnaces, rolling equipment bear frequent impact loads, requiring strong instant overload performance
- Multiple high-power equipment operates simultaneously, causing severe grid harmonic distortion and voltage fluctuation
- Furnace fans & cooling pumps run 24/7 with variable load, fixed-speed motors generate huge idle power waste
- Frequent start-stop of casting and conveying machinery creates violent mechanical shock, shortening equipment service life
Core Advantages
Metallurgy customized high temperature & anti-corrosion heavy-duty VFD strengths
High Temperature & Anti-Corrosion Sealed Cabinet
Independent air-cooled heat dissipation, anti-corrosion coating, dust-proof sealed design, long-term stable operation under high-temperature corrosive metallurgy environment.
Ultra-Low Harmonic Three-Level Topology
Effectively suppress grid distortion, meet metallurgy plant power access standards, avoid interference to precision smelting & casting control instruments.
Super Heavy-Load Overload Capacity
200% overload capacity for 60s, perfectly cope with shock loads of metal rolling, stirring and material conveying equipment.
Comprehensive Energy Saving & Soft Start Control
Smooth S-curve start eliminates mechanical impact; dynamic speed adjustment matches actual production load, cutting auxiliary power consumption by 22%~36%.
