The purpose of this project is to design a microwave based positioning system for use on an oxygen lance in an electrical arc furnace. The focus of this project is to determine the distance between the lance tip and the molten steel bath. This is to be accomplished using the lance as the waveguide, and developing hardware and software that will translate the reflected microwave signal into a distance from the steel bath. This distance measurement will allow optimization of the oxygen lance, which will speed the melting process and reduce the risk of costly lance damage. Keystone Steel and Wire funded this project.
