A new high-performance boron nitride ceramic tube is now available for use in basic oxygen furnaces during steelmaking. This advanced component is designed specifically for high-temperature gas injection lances. It offers exceptional thermal stability and resistance to molten slag and metal corrosion.

Basic oxygen furnaces operate under extreme conditions. Temperatures often exceed 1,700°C. Standard materials degrade quickly in this harsh environment. The boron nitride ceramic tube maintains its structural integrity even at these intense heat levels. It also resists chemical attack from aggressive furnace atmospheres.
Steel producers face constant pressure to improve efficiency and reduce downtime. Wear on gas injection lances has been a persistent issue. Frequent replacements slow production and raise costs. The new boron nitride solution significantly extends service life. This leads to fewer interruptions and more consistent operations.
The material’s low thermal expansion helps prevent cracking during rapid heating and cooling cycles. Its smooth surface reduces buildup of residues. That makes cleaning easier and improves gas flow consistency. These features support stable oxygen injection, which is critical for precise control of the steelmaking process.
Manufacturers tested the tubes in real-world furnace conditions. Results showed marked improvements in durability compared to traditional alumina or magnesia-based ceramics. Operators reported less maintenance and longer intervals between lance changes.
This innovation comes at a time when the steel industry seeks reliable ways to cut energy use and emissions. Better-performing components like the boron nitride tube contribute directly to those goals. They allow furnaces to run hotter and cleaner without sacrificing equipment life.
