What Are Outer Nozzles in BOF?
Outer nozzles in a BOF are used to direct gas flow from the tuyeres into the molten bath. They are exposed to extreme temperatures, chemical corrosion from slag and molten metal, and mechanical stress during blowing operations. These harsh conditions demand advanced refractory materials that can maintain performance without rapid wear or failure.
Why Refractory Quality Matters
Using the right refractory composition for BOF outer nozzles ensures:
- High thermal shock resistance – to withstand rapid temperature changes.
- Superior erosion resistance – for longer service intervals.
- Consistent gas flow – maintaining optimal steel refining conditions.
- Operational safety – reducing the risk of nozzle damage or failure.
At Pennekamp Middle East, we supply outer nozzles made from carefully selected raw materials like high-purity alumina, magnesia, and carbon blends to offer optimal performance and durability.
