Description
Application:
- The water-cooled oxygen lance / supersonic oxygen jet lance is an important tool used during the Basic Oxygen Steelmaking process. It is used to blow pure oxygen at supersonic speeds over hot metal in a furnace, which ignites the carbon dissolved in steel, and converts it into carbon dioxide and carbon monoxide, which in turn raises the temperature of the furnace to 1700°C. This helps in melting the steel, and reducing the carbon content and impurities resulting in better quality steel.
- Copper tuyeres are a critical component in basic oxygen furnace (BOF) sidérurgie, where they are used to inject high-purity oxygen into the molten steel bath.
- The oxygen injection through the copper tuyeres promotes the rapid oxidation and removal of impurities such as carbon, silicon, and other elements, enabling the efficient refining of the steel composition.
- Copper tuyeres are widely employed in modern integrated steel mills and mini-mills, as they are an essential technology for achieving high-productivity and high-quality steel production.
Performance:
- The high thermal conductivity of copper allows the tuyeres to effectively transfer heat from the hot oxygen stream to the surrounding refractory materials, protecting the furnace structure.
- Careful design of the copper tuyere geometry, such as the nozzle shape and orientation, optimizes the oxygen injection patterns to maximize the efficiency of the steelmaking process.
- Copper tuyeres demonstrate excellent resistance to the extreme temperatures and corrosive environments encountered in BOF steelmaking, ensuring reliable and consistent performance over extended periods.
