30T Industrial Electric Ladle Refining Furnace with Three Electrode Arc Heating System
30T Electric Ladle Refining Furnace with Three Electrode Arc Heating System
The 30T Electric Ladle Refining Furnace (LF) uses a three-electrode arc heating system for precise temperature control, desulfurization and alloy composition adjustment. It is a compact and efficient solution for small and medium steelmaking plants.
Key Selling Points
- Three-Electrode Arc Heating: Stable arc power keeps the molten steel temperature uniform and controllable.
- Precise Temperature Control: PLC automatic electrode regulation maintains the set tapping temperature.
- Desulfurization and Refining: Reducing slag operation lowers sulfur and inclusion content.
- Compact Design: 30-ton capacity suits small and medium batch production with lower investment.
- Easy Operation: HMI touch screen with real-time monitoring and fault alarms.
Working Principle
The ladle with molten steel is placed under the furnace roof. Three graphite electrodes heat the slag and steel by arc, while slag and alloy additions refine the steel and adjust its composition.
