3000KVA-9000KVA Ferroalloy Refining Furnace for High Carbon Ferrochrome Production with 2750-5300mm Hearth Diameter
This high-performance electric arc refining furnace is engineered for large-scale production of various ferroalloys and non-metallic materials. Designed to enhance main metal content in ferroalloys, it serves as critical equipment for refining products from submerged arc furnaces.
This furnace efficiently processes multiple ferroalloy types including:
- High titanium slag and ferronickel
- Ferrochromium and ferromanganese
- Ferrosilicon and tungsten slag
- Low to medium carbon ferroalloys
- Multiple structural configurations: fixed, tilting, or rotating furnace body
- Water wall hanging slag capability for varying smelting quality requirements
- Advanced power supply options: conductive cross arm or electrode holder
- PLC automatic control technology for precise operation
- High-accuracy furnace top charging with weighing sensors
- Water-cooled copper tube secondary bus and large section water-cooled cables for reduced system impedance
The furnace system includes: furnace cover, furnace body, tilting mechanism, electrode lifting mechanism, water cooling cable, short network, water cooling system, hydraulic system, high voltage system, transformer, and voltage electric control with automation system.
