The lance body/tube is the main structural component of an oxygen lance system. It houses and protects the internal oxygen delivery channels and cooling systems, providing mechanical strength and thermal resistance during steelmaking operations.
Common materials include low carbon steel, stainless steel, and copper alloys. The specific material grade, such as 20G carbon steel, is selected based on the application's temperature and pressure requirements.
Typical reference ranges are: outer diameter 89–219 mm, wall thickness 6–20 mm, and length 3000–12000 mm. These values must be confirmed for the specific model and furnace geometry.
Cooling water circulates through annular spaces within the tube. The flow rate is typically 30–80 m³/h, and the pressure drop is 0.2–0.5 MPa. Proper cooling prevents thermal damage and ensures safe operation.
