BOF Oxygen Lance Tip Laser Scanning and 3D Modeling for Wear Evaluation (Room 409)

The BOF oxygen lance tip is a critical piece of equipment that controls the oxygen steelmaking process and plays an important role in the life of the vessel refractory. Lance tip life varies greatly from shop to shop and understanding and reducing lance failures is important for production, quality and safety. To better measure lance tip wear, an experimental laser scanning method was developed that creates 3D models of lance tips. Used lance tips were scanned and modeled using the experimental method, and lance tip wear was compared to the original surface and correlated against process data.
