Slag splashing in electric arc furnaces (EAF) and basic oxygen furnaces (BOF) utilizes high-pressure nitrogen jets to blow molten slag against refractory wall linings, forming a protective sacrificial layer.
1. Multi-Phase Supersonic CFD Simulation
MacProtec modeled supersonic nitrogen gas jets interacting with high-temperature molten slag:
- Predicting slag droplet ejection trajectories, velocity vectors, and wall impingement angles.
- Calculating slag solidifying rates as a function of MgO saturation and furnace wall thermal boundary conditions.
2. Furnace Campaign Extension Results
- Achieved uniform slag coating thickness of 25-40mm across high-wear furnace knuckle zones.
- Doubled refractory campaign duration, significantly decreasing specific gunning mix consumption.
